Typescript Eslint Description
TypeScript ESLint is a tool, introduced in 2019 by the TypeScript team at Microsoft, that facilitates the seamless integration of ESLint, a popular static code analysis tool for identifying problematic patterns found in JavaScript code, with TypeScript, a statically typed superset of JavaScript.
By extending ESLint’s capacities to understand TypeScript syntax, this tool enables ESLint to enforce coding standards on TypeScript codebases through a specific set of standalone rules which is very useful for the consistency of the code. Each developer has their own way of writing code and, without consistent styling, the codebase can appear messy and more prone to errors.
TypeScript ESLint is a very active project with a large community of contributors, as we can see there are currently more than 500 contributors:
Additionally, it has regular commits, discussions and releases + 271 releases
TypeScript ESLint plays a very important role in TypeScript development workflows since it helps developers catch errors, enforce coding styles, and maintain code quality.
The typescript-eslint project exists to enable ESLint to work seamlessly with TypeScript code. Since ESLint's default JavaScript parser cannot understand TypeScript syntax, typescript-eslint bridges this gap by allowing ESLint to parse TypeScript code.
In summary, the typescript-eslint:
- Allows ESLint to parse TypeScript syntax
- Creates a set of tools for ESLint rules to be able to use TypeScript's type information
- Provides a large list of lint rules that are specific to TypeScript and/or use that type information
Based on the package.json file, the typescript-eslint project seems to utilize various technologies and tools. Here are some examples:
-
TypeScript: The project is primarily written in TypeScript;
-
ESLint: The project utilizes ESLint for linting JavaScript and TypeScript code;
-
Prettier: Prettier is used for code formatting;
-
Jest: Jest is the testing framework used;
-
NX: NX appears to be used for managing monorepos;
-
Husky and lint-staged: These are used for setting up pre-commit hooks;
-
cspell: Used for spellchecking;
-
Babel: Babel is utilized for transpilation.
These technologies collectively are mainly used for linting, formatting, testing, managing monorepos, spellchecking, and other development-related tasks within the typescript-eslint project.

The typescript-eslint project began in 2019 with the aim of enabling ESLint, a popular JavaScript linting tool, to also support TypeScript code. This initiative was driven by the increasing adoption of TypeScript.
Since its inception, the typescript-eslint project has evolved significantly, with regular updates, enhancements, and bug fixes to improve its compatibility, performance, and feature set.
Currently, the last release is v7.1.0 - latest.
The project is currently in active maintenance, characterized by a release process that occurs automatically from the latest commit on the main branch through GitHub Actions. Despite the absence of a predefined schedule for major releases, the project demonstrates a proactive approach to maintaining code quality and stability while prioritizing forward progression by refraining from back-porting releases to previously published version.
The TypeScript ESLint has a considerable number of open issues covering various aspects of the tool, including new feature requests, bug reports, documentation enhancements, and more. By utilizing the label option on the GitHub repository, users can see how many issues are open and categorized accordingly.
Currently, there are 404 open issues and 3,861 closed issues:
Additionally, the official TypeScript ESLint website provides guidelines for managing GitHub issues effectively within the TypeScript ESLint project. These guidelines aim to ensure clarity and foster engagement among contributors.
