1-5: Improve project metadata for better documentation.Consider making the following improvements to the project metadata:
- Update the
mainfield to point to the correct entry point (e.g., "dist/server.js" after compilation).- Add a meaningful
descriptionto provide context about the project.- Include relevant
keywordsto improve discoverability.- Specify the
authorinformation.Example:
{ "name": "unsubscribe-automation", "version": "1.0.0", "description": "A Playwright-based automation tool for email unsubscription processes", "main": "dist/server.js", "keywords": ["email", "unsubscribe", "automation", "playwright"], "author": "Your Name <your.email@example.com>", "license": "ISC" }Also applies to: 11-13
6-10: Enhance scripts section with additional development tools.The current scripts are a good start, but consider adding the following to improve the development workflow:
- Implement the
testscript with an appropriate testing framework.- Add a
lintscript for code linting (e.g., ESLint).- Add a
formatscript for code formatting (e.g., Prettier).- Add a
devscript for running the server in development mode with auto-restart.Example:
"scripts": { "start": "ts-node -r tsconfig-paths/register src/server.ts", "build": "tsc", "test": "jest", "lint": "eslint . --ext .ts", "format": "prettier --write \"src/**/*.ts\"", "dev": "nodemon --exec ts-node -r tsconfig-paths/register src/server.ts" }Don't forget to install the necessary dev dependencies for these scripts.
14-21: Enhance development dependencies for improved code quality and testing.Consider making the following improvements to the development dependencies:
- Add ESLint for code linting:
"eslint": "^8.0.0","@typescript-eslint/eslint-plugin": "^5.0.0","@typescript-eslint/parser": "^5.0.0"- Add Prettier for code formatting:
"prettier": "^2.0.0"- Add Jest for testing:
"jest": "^29.0.0","@types/jest": "^29.0.0","ts-jest": "^29.0.0"- Use a caret range for @types/node to allow minor and patch updates:
"@types/node": "^22.5.4"Example:
"devDependencies": { "@types/dotenv": "^8.2.0", "@types/jest": "^29.0.0", "@types/node": "^22.5.4", "@typescript-eslint/eslint-plugin": "^5.0.0", "@typescript-eslint/parser": "^5.0.0", "eslint": "^8.0.0", "jest": "^29.0.0", "playwright": "^1.47.2", "prettier": "^2.0.0", "ts-jest": "^29.0.0", "ts-node": "^10.9.2", "tsconfig-paths": "^4.2.0", "typescript": "^5.6.2" }unsubscribe-automation/src/server.ts (1)
47-47: Useserver.log.infoinstead ofconsole.logfor logging.For consistency and to leverage Fastify's logging system, replace
console.logwithserver.log.info.Apply this diff to update the logging method:

22-29: Clarify and adjust runtime dependencies.The current dependencies look good, but consider the following adjustments:
Move
playwrightfrom devDependencies to dependencies, as it's likely needed for runtime automation:"playwright": "^1.47.2"Clarify the purpose of the
aipackage. If it's not necessary, consider removing it.Consider adding
@playwright/testas a dev dependency if you plan to use Playwright's built-in test runner:"devDependencies": { "@playwright/test": "^1.47.2" }Ensure that the version of
@fastify/cors(^10.0.1) is compatible with the version offastify(^5.0.0) you're using. You might want to use a version that matches your Fastify major version.To verify the compatibility between Fastify and @fastify/cors, you can run:

Use import type for types-only imports to optimize module loading
The Page import is only used as a type in your code. By using import type, you ensure that the type is removed during transpilation, which can improve performance and avoid loading unnecessary modules.

Potentially more robust solution provided by Claude:
import { Page, ElementHandle } from 'playwright';
async function performFallbackUnsubscribe(page: Page): Promise<boolean> {
const unsubscribeKeywords = [
'unsubscribe', // English
'désabonner', // French
'abbestellen', // German
'cancelar suscripción', // Spanish
'annulla iscrizione', // Italian
'退订', // Chinese (Simplified)
'退訂', // Chinese (Traditional)
'退会', // Japanese
'отписаться', // Russian
'se désabonner', // Alternative French
'désinscription', // Another French alternative
'abmelden', // Alternative German
'darse de baja', // Alternative Spanish
];
const generateSelectors = (keyword: string) => [
`button:has-text("${keyword}")`,
`a:has-text("${keyword}")`,
`input[type="submit"][value*="${keyword}" i]`,
`:text("${keyword}")`,
`[aria-label*="${keyword}" i]`,
`[title*="${keyword}" i]`,
];
const allSelectors = unsubscribeKeywords.flatMap(generateSelectors);
for (const selector of allSelectors) {
try {
const elements = await page.$$(selector);
if (elements.length > 0) {
// Filter visible elements
const visibleElements = await Promise.all(
elements.map(async (el) => (await el.isVisible()) ? el : null)
);
const element = visibleElements.find((el) => el !== null) as ElementHandle<Element> | undefined;
if (element) {
await element.click({ timeout: 5000 });
console.log(`Successfully clicked unsubscribe element: ${selector}`);
return true;
}
}
} catch (error) {
console.warn(`Error trying to click ${selector}:`, error);
}
}
console.log('No unsubscribe element found or clicked in fallback strategy');
return false;
}And it's explanation in case you disagree with its reasoning:
Here are the key improvements made to the function:
Return value: The function now returns a boolean indicating success or failure, which can be useful for error handling or flow control in the calling code.
Error handling: Each selector attempt is now wrapped in a try-catch block, allowing the function to continue trying other selectors if one fails.
Visibility check: The function now checks for element visibility before attempting to click, which can help avoid clicking on hidden elements.
Use of $$ instead of locator: This change allows for more precise element selection and easier handling of multiple matching elements.
Timeout handling: The click timeout is still set to 5000ms, but now it's handled more gracefully within the try-catch block.
TypeScript types: Added proper type annotations for better type safety and code clarity.
Flexibility: The selectors array is now easier to extend with additional selectors if needed.
These changes should make the function more robust and reliable for finding and clicking unsubscribe elements across various webpage structures. The function will try all selectors, handle errors gracefully, and only attempt to click visible elements.

apps/unsubscribe-automation/.env.example (4)
1-1: Add a comment explaining the GOOGLE_GENERATIVE_AI_API_KEY.While it's good practice to leave the API key value empty in the .env.example file, consider adding a comment explaining the purpose of this key and how developers can obtain it. This will help new contributors set up the project more easily.
Consider adding a comment like this:
+# Google Generative AI API key for LLM integration +# Obtain this key from the Google Cloud Console: https://console.cloud.google.com/ GOOGLE_GENERATIVE_AI_API_KEY=
2-3: LGTM! Consider adding a note about production settings.The CORS_ORIGIN variable is well-documented and appropriately set for development.
Consider expanding the comment to remind developers about production settings:
-# If required, set CORS_ORIGIN to allow requests from your frontend +# If required, set CORS_ORIGIN to allow requests from your frontend +# Note: Update this value for production environments CORS_ORIGIN="http://localhost:3000"
4-4: Add a comment explaining NODE_ENV and its possible values.While setting NODE_ENV to "development" is appropriate for a .env.example file, it would be helpful to add a comment explaining the significance of this variable and mentioning other possible values.
Consider adding a comment like this:
+# Node environment: development, test, or production +# This affects various behaviors in Node.js applications NODE_ENV="development"
1-4: Consider adding a header comment to the file.To improve the overall documentation of the project, consider adding a header comment to this .env.example file. This comment could explain the purpose of the file and provide instructions for developers on how to use it.
Here's a suggested header comment:
+# This is an example environment file for the unsubscribe-automation service. +# Copy this file to .env and fill in the appropriate values for your environment. +# Do not commit the actual .env file to version control.

1-5: Enhance project metadata for better documentation.Consider making the following improvements to the project metadata:
- Add a concise description of the project in the "description" field.
- Update the "main" field to "dist/server.js" to match the TypeScript output.
- Add relevant keywords to improve discoverability.
- Specify the author or organization responsible for the project.
These changes will provide better context and improve the project's documentation.
Also applies to: 11-13
6-10: Enhance scripts for development and production use.The current scripts are a good start, but consider the following improvements:
- Add a production start script that runs the compiled JavaScript:
"start:prod": "node dist/server.js"- Rename the current start script to emphasize its use in development:
"start:dev": "ts-node -r tsconfig-paths/register src/server.ts"- Update the test script to use a testing framework like Jest:
"test": "jest"- Add a lint script for code quality:
"lint": "eslint . --ext .ts"These changes will provide a more comprehensive set of scripts for development, testing, and production use.
14-21: Enhance devDependencies for improved development experience.Consider the following suggestions for the devDependencies:
- Use a caret range for @types/node to allow minor version updates:
"@types/node": "^22.5.4"- Add ESLint for code linting:
"eslint": "^8.0.0"- Add Jest for testing:
"jest": "^29.0.0"and"@types/jest": "^29.0.0"- Consider adding
prettierfor code formattingThese additions will improve code quality, enable testing, and enhance the overall development experience.

85-99: Add a default case to handle unexpected action typesThe switch statement lacks a default case. Adding one can help catch and log any unexpected action types, improving robustness.
Here's the suggested addition:
switch (action.type) { case "click": case "submit": await locator.click({ timeout: 5000 }); break; case "fill": if (action.value) { await locator.fill(action.value, { timeout: 5000 }); } break; case "select": if (action.value) { await locator.selectOption(action.value, { timeout: 5000 }); } break; + default: + console.warn(`Unhandled action type: ${action.type}`); }

22-31: Review and optimize dependencies for consistency and stability.Consider the following suggestions for the dependencies:
- Evaluate the need for multiple AI-related packages (@ai-sdk/google, @ai-sdk/openai, @google/generative-ai, ai). Consider consolidating to reduce potential conflicts and simplify maintenance.
- Pin the fastify version to avoid potential breaking changes:
"fastify": "5.0.0"- Ensure that the versions of @ai-sdk/google and @ai-sdk/openai are compatible with each other and with the @google/generative-ai package.
- Consider adding a package for structured logging, such as pino, which integrates well with Fastify.
These changes will help maintain consistency and stability in your project dependencies.

Ensure compliance with data privacy when sending page content to AI services
The function analyzePageWithAI sends page content to an external AI service. If the page contains sensitive information, this could raise privacy concerns. Please verify compliance with data privacy regulations and consider sanitizing the content before transmission.
Would you like assistance in implementing content sanitization or establishing guidelines for handling sensitive data?

Simplify code by removing unnecessary 'else' clause
Since the if block at line 218 returns a value, the subsequent else clause is redundant and can be removed for cleaner code.
Here's the refactored code:
if (confirmationFound) {
console.log("Unsubscribe confirmation found.");
return true;
}
- else {
console.log("Unsubscribe action performed, but confirmation not found.");
// Only take screenshot if not in production
if (!isProduction) {
await page.screenshot({
path: "final-state-screenshot.png",
fullPage: true,
});
}
return false;
- }
+ console.log("Unsubscribe action performed, but confirmation not found.");
+ // Only take screenshot if not in production
+ if (!isProduction) {
+ await page.screenshot({
+ path: "final-state-screenshot.png",
+ fullPage: true,
+ });
+ }
+ return false;By removing the else clause, the code after the if condition executes only when confirmationFound is false, improving readability.

Add error handling for the AI service call
The call to generateText may fail due to network issues or API errors. Consider adding a try-catch block to handle potential exceptions from the AI service.
Here's a suggested modification:
+ let analysisText: string;
+ try {
const { text } = await generateText({
model: google("gemini-1.5-flash"),
prompt: prompt,
});
+ analysisText = text;
+ } catch (error) {
+ console.error("Error generating AI analysis:", error);
+ throw new Error("Failed to generate AI analysis");
+ }This ensures that any errors from the AI service are appropriately caught and handled.

Avoid reassigning function parameters; use a local variable instead
Reassigning the function parameter pageContent can lead to confusion and unintended side effects. It's better practice to assign the modified value to a new local variable.
Here's a suggested fix:
async function analyzePageWithAI(pageContent: string): Promise<PageAnalysis> {
const maxContentLength = 20000; // Adjust based on API limitations
+ let contentToAnalyze = pageContent;
- if (pageContent.length > maxContentLength) {
+ if (contentToAnalyze.length > maxContentLength) {
console.warn(
`Page content exceeds ${maxContentLength} characters. Truncating...`,
);
- pageContent = pageContent.substring(0, maxContentLength);
+ contentToAnalyze = contentToAnalyze.substring(0, maxContentLength);
}Then, replace instances of pageContent with contentToAnalyze where appropriate in the rest of the function.

🛠️ Refactor suggestion
Optimize visibility checks in the fallback strategy
In performFallbackUnsubscribe, using Promise.all for visibility checks can be resource-intensive. Consider using Playwright's locator.filter() method for more efficient element selection.
Refactored code:
for (const selector of allSelectors) {
try {
- const elements = await page.$$(selector);
- if (elements.length > 0) {
- // Filter visible elements
- const visibleElements = await Promise.all(
- elements.map(async (el) => ((await el.isVisible()) ? el : null)),
- );
- const element = visibleElements.find((el) => el !== null) as
- | ElementHandle<Element>
- | undefined;
+ const element = await page.locator(selector).filter({ hasText: /./ }).first();
if (element) {
await element.click({ timeout: 5000 });
console.log(`Successfully clicked unsubscribe element: ${selector}`);
return true;
}
} catch (error) {
console.warn(`Error trying to click ${selector}:`, error);
}
}This approach leverages Playwright's built-in methods for a more efficient and readable solution.

Refer to the [Playwright installation guide](https://playwright.dev/docs/intro#installation) for more information. - Check the console output for error messages or logs that might indicate the cause of any issues. - Common issues and solutions: 1. "API key invalid": Verify that your API keys in the .env file are correct and properly formatted. 2. "CORS error": Ensure the `CORS_ORIGIN` in your .env file matches your frontend application's URL. 3. "Timeout error": Check your internet connection and try increasing the timeout value in the configuration. - To enable verbose logging, set the `DEBUG` environment variable:DEBUG=* pnpm start

Potential PII Leakage by Sending Raw HTML Content to AI Model
The analyzePageWithAI function sends the raw HTML content of the page to the AI model for analysis. This content may include sensitive user information or PII.
Consider sanitizing the pageContent to remove or mask any sensitive information before including it in the AI prompt. This helps protect user privacy and complies with data protection regulations.

🧹 Outside diff range and nitpick comments (13)
apps/unsubscriber/tsconfig.json (1)
14-15: Include and exclude patterns look good, with a minor suggestion.The current include and exclude patterns are appropriate for most TypeScript projects:
- Including all files under the
srcdirectory is a common and good practice.- Excluding
node_modulesis necessary to prevent TypeScript from type-checking dependencies.Consider explicitly excluding test files and other non-production code if they exist in your project. This can help optimize the compilation process. For example:
"include": ["src/**/*"], -"exclude": ["node_modules"] +"exclude": ["node_modules", "**/*.test.ts", "**/*.spec.ts"]This change would exclude test files with
.test.tsor.spec.tsextensions from the production build.apps/unsubscriber/package.json (4)
1-6: Update the main entry pointThe
"main"field is set to"index.js", but the start and dev scripts use"src/server.ts". Consider updating the main entry point to match the actual entry file.Apply this change:
- "main": "index.js", + "main": "src/server.ts",
7-12: Implement actual testsThe test script is currently a placeholder. Consider implementing actual tests for the project to ensure code quality and prevent regressions.
Would you like assistance in setting up a testing framework and writing initial tests?
13-19: Use consistent versioning for dependenciesFor consistency with other dependencies, consider using a caret range for
@types/node.Apply this change:
- "@types/node": "22.5.4", + "@types/node": "^22.5.4",
20-29: Dependencies look good, consider adding explanatory commentsThe selected dependencies align well with the project's goals. To improve maintainability, consider adding comments to explain the purpose of less common dependencies like
@ai-sdk/google,@ai-sdk/openai, and@t3-oss/env-core.Example:
"dependencies": { // AI SDKs for Google and OpenAI integration "@ai-sdk/google": "^0.0.51", "@ai-sdk/openai": "^0.0.59", // ... // Type-safe environment variable handling "@t3-oss/env-core": "^0.11.1", // ... }apps/unsubscriber/src/env.ts (1)
5-11: LGTM: Environment configuration is well-structured and secure.The environment configuration is well-defined and uses appropriate validation:
- NODE_ENV is correctly restricted to specific values.
- GOOGLE_GENERATIVE_AI_API_KEY is required and must be non-empty, which is good for security.
- CORS_ORIGIN is optional, allowing for flexibility in deployment.
Consider adding a minimum value check for PORT to ensure it's a valid port number:
- PORT: z.number().default(5000), + PORT: z.number().min(1).max(65535).default(5000),apps/unsubscriber/README.md (5)
20-44: LGTM: Clear installation instructions with a minor suggestionThe installation section provides clear and comprehensive instructions. The inclusion of the Google AI API key link is particularly helpful.
Consider adding a note about the security implications of API keys in the
.envfile. For example:Note: Keep your `.env` file secure and never commit it to version control.🧰 Tools

45-66: LGTM: Clear usage instructions with a suggestion for improvementThe instructions for running the service and using the unsubscribe endpoint are clear and helpful. The curl example is a good addition.
Consider using a more realistic example for the unsubscribe URL in the curl command. For instance:
- "url": "https://example.com/unsubscribe" + "url": "https://newsletter.example.com/unsubscribe?user=johndoe@email.com&token=abc123"This would better illustrate a typical unsubscribe URL structure.

Consider expanding the endpoint descriptions to provide more context. For example:
- `GET /`: Health check endpoint. Returns a 200 OK status if the service is running. - `POST /unsubscribe`: Trigger the unsubscribe process. Accepts a JSON payload with a `url` field containing the unsubscribe link.This additional information would give users a clearer understanding of each endpoint's purpose and usage.

85-88: LGTM: Helpful troubleshooting section with suggestion for expansionThe troubleshooting section provides useful guidance for common issues, particularly related to Playwright.
Consider expanding the troubleshooting section with more specific tips related to this service. For example:
- If you encounter "Access Denied" errors, ensure that your Google AI API key is correctly set in the `.env` file and has the necessary permissions. - If the unsubscribe process fails, try running the service with increased verbosity (e.g., `DEBUG=* pnpm start`) to get more detailed logs for debugging. - Ensure that your machine's date and time are correctly set, as this can affect API authentication.These additional tips would help users troubleshoot issues specific to this unsubscribe automation service.

80-141: Well-implemented action performer with room for simplificationThe
performUnsubscribeActionsfunction is robust, with good practices like retry mechanisms and visibility checks. However, the retry logic could be simplified for better readability.Consider simplifying the retry logic:
for (const action of actions) { - let retries = 0; - while (retries < MAX_RETRIES) { + for (let retries = 0; retries < MAX_RETRIES; retries++) { try { // ... (existing action logic) break; // Success, exit retry loop } catch (error) { console.warn( `Failed to perform action: ${action.type} on ${action.selector}. Retry ${retries + 1}/${MAX_RETRIES}. Error: ${error}`, ); - retries++; - if (retries >= MAX_RETRIES) { + if (retries >= MAX_RETRIES - 1) { console.error( `Max retries reached for action: ${action.type} on ${action.selector}`, ); } } // ... (existing delay logic) } }This change simplifies the loop structure while maintaining the same functionality.
143-196: Robust fallback unsubscribe implementation with potential for enhancementThe
performFallbackUnsubscribefunction is well-implemented with a comprehensive list of multilingual keywords and various selector strategies. The visibility check before clicking is a good practice.Consider adding a retry mechanism for individual selector attempts to handle potential transient issues:
for (const selector of allSelectors) { + const MAX_RETRIES = 3; + for (let retry = 0; retry < MAX_RETRIES; retry++) { try { // ... (existing element finding and clicking logic) + break; // Success, exit retry loop } catch (error) { - console.warn(`Error trying to click ${selector}:`, error); + console.warn(`Error trying to click ${selector} (attempt ${retry + 1}/${MAX_RETRIES}):`, error); + if (retry < MAX_RETRIES - 1) { + await page.waitForTimeout(1000); // Wait before retrying + } } + } }This enhancement could improve the robustness of the fallback strategy by handling transient issues.

🛠️ Refactor suggestion
Consider updating TypeScript compiler options for better compatibility and features.
The current configuration is good, but there are a few suggestions for improvement:
- Update the
targetandmoduleto more recent versions (e.g., ES2020 or ES2022) for better performance and features, if your deployment environment supports it. - The
"moduleResolution": "bundler"is a newer option and might not be supported by all tools. Consider using"node"if you encounter any compatibility issues. - Be cautious with
"skipLibCheck": trueas it can hide issues in declaration files. Consider setting it tofalseif you want stricter type checking.
Here's a suggested update to the compiler options:
"compilerOptions": {
- "target": "es2018",
- "module": "es2015",
+ "target": "es2020",
+ "module": "es2020",
"moduleResolution": "bundler",
- "lib": ["es2018", "dom"],
+ "lib": ["es2020", "dom"],
"strict": true,
"esModuleInterop": true,
- "skipLibCheck": true,
+ "skipLibCheck": false,
"forceConsistentCasingInFileNames": true,
"outDir": "./dist",
"rootDir": "./src"
},These changes will enable more recent JavaScript features and stricter type checking.

Clarify OpenAI API key requirement
The prerequisites section mentions an OpenAI API key, but it's not included in the .env setup instructions later in the README. This might confuse users.
Consider one of the following actions:
- If the OpenAI API key is required, add it to the
.envsetup instructions. - If it's not required, remove it from the prerequisites list.
- If it's optional, clarify this in the prerequisites section.

Well-implemented AI analysis function with room for improvement
The analyzePageWithAI function is well-structured and includes good practices such as content truncation and timeout handling. However, there's a potential issue with logging the raw AI response.
To address the potential PII leakage, consider removing or sanitizing the logging of the raw AI response:
console.error("Error parsing AI response:", error);
-console.error("Raw AI response:", analysisText);
+// Log a sanitized version or remove this lineThis change will help prevent potential exposure of sensitive information that may be included in the AI's output.

Well-structured main function with areas for improvement
The autoUnsubscribe function is well-implemented, covering URL validation, AI-driven unsubscription, fallback strategies, and error handling. However, there are two areas that could be improved:
- Confirmation detection logic
- Secure handling of screenshots
Enhance the confirmation detection logic to avoid potential false positives:
const confirmationFound = analysis.confirmationIndicator
? await page.$(analysis.confirmationIndicator).then(Boolean)
- : finalContent.toLowerCase().includes("unsubscribed") ||
- finalContent.toLowerCase().includes("successfully");
+ : /unsubscribed|you have been removed|successfully unsubscribed/i.test(finalContent);This change uses a more specific regex pattern to detect unsubscription confirmation, reducing the chance of false positives.
Handle screenshots more securely to protect potentially sensitive information:
if (!isProduction) {
+ // Implement a function to mask sensitive areas before capturing screenshots
+ await maskSensitiveAreas(page);
await page.screenshot({
path: "final-state-screenshot.png",
fullPage: true,
});
}Implement a maskSensitiveAreas function that hides or blurs areas of the page that might contain sensitive information before taking screenshots. This helps prevent accidental capture of personal data in error reports.

8-19: Overall implementation looks good, with some suggestions for improvement.The
getModelfunction is well-structured and correctly implements the multi-provider support. However, consider the following improvements:
- Add a default case to the switch statement to handle potential invalid providers:
default: throw new Error(`Unsupported provider: ${provider}`);
- Consider using environment variables for model identifiers to make updates easier:
case "google": return google(process.env.GOOGLE_MODEL_ID || "gemini-1.5-flash");
- Add error handling for provider-specific function calls:
try { return google(modelId); } catch (error) { console.error(`Error initializing Google model: ${error.message}`); throw error; }These changes will improve the robustness and maintainability of the function.
apps/unsubscriber/src/main.ts (3)
1-16: LGTM! Consider grouping related imports and constants.The imports and constants are well-defined and appropriate for the functionality. To improve readability, consider grouping related imports and constants together.
You could group the imports like this:
import { chromium } from "playwright"; import type { Page, ElementHandle, Locator } from "playwright"; import { z } from "zod"; + import { generateText } from "ai"; -import { env } from "./env"; import { getModel } from "./llm"; +import { env } from "./env"; const MAX_CONTENT_LENGTH = 20_000; // Adjust based on API limitations const AI_TIMEOUT = 30_000; +// Playwright-related constants const NETWORK_IDLE_TIMEOUT = 10_000; const MAX_RETRIES = 3; // Limit retries to 3 to avoid infinite loops const RETRY_DELAY = 1_000; // Delay between retries in milliseconds const ACTION_TIMEOUT = 5_000; // Timeout for each action in milliseconds const ACTION_DELAY = 2_000; // Delay between actions in milliseconds
76-149: Well-structured action execution with room for optimizationThe
performUnsubscribeActionsandperformActionfunctions are well-implemented with good error handling and logging. The separation of concerns between these functions improves readability.Consider simplifying the retry logic in
performUnsubscribeActionsfor better readability:- for (const action of actions) { - let retries = 0; - while (retries < MAX_RETRIES) { + for (const action of actions) { + for (let retries = 0; retries < MAX_RETRIES; retries++) { try { // ... (existing code) break; // Success, exit retry loop } catch (error) { // ... (existing code) - retries++; - if (retries >= MAX_RETRIES) { + if (retries === MAX_RETRIES - 1) { console.error( `Max retries reached for action: ${action.type} on ${action.selector}`, ); } else { await page.waitForTimeout(RETRY_DELAY); } } } // ... (existing code) }This change simplifies the loop structure and makes the retry logic more straightforward.
151-204: Robust fallback strategy with potential for optimizationThe
performFallbackUnsubscribefunction is well-implemented with a comprehensive multilingual approach. The error handling and visibility checking are appropriately handled.Consider optimizing the selector generation logic for better maintainability:
- const generateSelectors = (keyword: string) => [ - `button:has-text("${keyword}")`, - `a:has-text("${keyword}")`, - `input[type="submit"][value*="${keyword}" i]`, - `:text("${keyword}")`, - `[aria-label*="${keyword}" i]`, - `[title*="${keyword}" i]`, - ]; + const selectorTemplates = [ + (keyword: string) => `button:has-text("${keyword}")`, + (keyword: string) => `a:has-text("${keyword}")`, + (keyword: string) => `input[type="submit"][value*="${keyword}" i]`, + (keyword: string) => `:text("${keyword}")`, + (keyword: string) => `[aria-label*="${keyword}" i]`, + (keyword: string) => `[title*="${keyword}" i]`, + ]; + + const generateSelectors = (keyword: string) => selectorTemplates.map(template => template(keyword));This change separates the selector templates from the generation logic, making it easier to maintain and extend in the future.

17-28: Well-structured schema and type definition.The Zod schema for page analysis results is well-defined, covering all necessary fields for unsubscribe actions. Deriving the TypeScript type from the Zod schema ensures consistency between runtime validation and static typing.
206-259:⚠️ Potential issueWell-structured main function with areas for improvement
The
autoUnsubscribefunction is well-implemented, covering URL validation, AI-driven unsubscription, fallback strategies, and error handling. However, there's an area that could be improved:Enhance the confirmation detection logic to avoid potential false positives:
const confirmationFound = analysis.confirmationIndicator ? await page.$(analysis.confirmationIndicator).then(Boolean) - : finalContent.toLowerCase().includes("unsubscribed") || - finalContent.toLowerCase().includes("successfully"); + : /unsubscribed|you have been removed|successfully unsubscribed/i.test(finalContent);This change uses a more specific regex pattern to detect unsubscription confirmation, reducing the chance of false positives.

Improve security measures for error screenshots
The error handling and logging in the autoUnsubscribe function are comprehensive. However, there's a potential security risk with capturing screenshots that may contain sensitive information.
Consider implementing a function to mask sensitive areas before capturing screenshots:
if (!isProduction) {
+ await maskSensitiveAreas(page);
await page.screenshot({
path: "final-state-screenshot.png",
fullPage: true,
});
}Implement a maskSensitiveAreas function that hides or blurs areas of the page that might contain sensitive information before taking screenshots. This helps prevent accidental capture of personal data in error reports.
Would you like assistance in implementing the maskSensitiveAreas function?

Well-implemented AI analysis function with room for improvement
The analyzePageWithAI function is well-structured and includes good practices such as content truncation and timeout handling. However, there's a potential issue with logging the raw AI response.
To address the potential PII leakage, consider removing or sanitizing the logging of the raw AI response:
console.error("Error in AI analysis:", error);
-console.error(
- "Raw AI response:",
- error instanceof Error ? error.message : String(error),
-);
+console.error("AI analysis error details:", error instanceof Error ? error.message : String(error));This change will help prevent potential exposure of sensitive information that may be included in the AI's output.

@madhav-relish thanks for the PR! Most of the changes I made were just Cursor going over each section of code. One potentially big improvement would be to try click the button without using AI at all, with something like this: await page.getByText('Unsubscribe').click()And then for the different variations of this for different text that's common in unsub flows / different languages. The next step for this would be to integrate it with the core app. |
