Estimated code review effort: 2 (Simple) | ~15 minutes Merge Risk: 🔵 Low · up to The import change restores React 16–18 webpack compatibility without changing the public API or intended runtime behavior. The integration build gate still allows CRA warnings to pass, so merge is reasonable with explicit owner follow-up to strengthen that check.

In @.github/workflows/integration.yml:
- Around line 75-78: Remove the CI: false override from the “Build CRA example
(production)” workflow step so react-scripts enforces strict warning handling;
first resolve the existing CRA build warnings or add a separate strict CI build
while preserving the production build command.
- Around line 72-73: Update the “Install local SDK into CRA example” workflow
step to remove --legacy-peer-deps so npm enforces peer-dependency compatibility;
alternatively, add a subsequent dependency-tree validation step using npm ls
that fails when react, react-dom, or `@auth0/auth0-react` has invalid
dependencies.

react-scripts 5.0.1 build.js process.env.CI warnings treated as errors
💡 Result:
In react-scripts 5.0.1, the build process treats linter warnings as errors whenever the environment variable CI is set to true [1][2][3]. This is a built-in behavior of the scripts/build.js file within react-scripts, designed to ensure that code quality issues are addressed before production deployment [1][4][5]. Because most CI/CD platforms (like GitHub Actions, Netlify, and GitLab) automatically set the CI environment variable to true, this often causes builds to fail unexpectedly when warnings are present [4][6][5][7]. To resolve this behavior, you can override the CI environment variable during your build command [6][5]. Recommended Solutions: 1. Modify package.json (Cross-Platform Compatible) Install the cross-env package to ensure the environment variable is set correctly across different operating systems [5]: npm install --save-dev cross-env Then, update your build script in package.json [5]: "scripts": { "build": "cross-env CI=false react-scripts build" } 2. Platform-Specific Overrides If you do not wish to use cross-env, you can use platform-specific syntax in your package.json [6][3]: - For Linux/macOS: "build": "CI=false react-scripts build" [3] - For Windows (Command Prompt): "build": "set CI=false && react-scripts build" [6][3] 3. Deployment Platform Settings Alternatively, you can configure your CI/CD platform directly to ignore this behavior by explicitly setting the CI environment variable to false in your platform's dashboard or configuration file (e.g.,.yml) [6][5]. Note: This behavior is intended to maintain high code quality [4][5]. The most robust long-term solution is to resolve the underlying linter warnings in your codebase rather than disabling the check [5].

Do not weaken the CRA build gate with CI: false.
react-scripts treats warnings as errors when CI is not false. Remove this override after fixing existing warnings, or add a separate strict CI build.

**Fixed** - fix: update import style in useAuth0Suspense for compatibility with React older version [\#1206](#1206) ([gyaneshgouraw-okta](https://github.com/gyaneshgouraw-okta))
3 participants
Summary
Fixes #1205. Restores React 16–18 compatibility for webpack-based consumers after 2.24.0 introduced a build-time error for React 19's
useexport.Root Cause
useAuth0SuspenseaccessedReact.usethrough a namespace import. Webpack statically validates namespace members and fails becauseuseis not exported by React 16–18, even when the hook is unused or runtime-guarded.Fix
Switch the React namespace import to a default import and use named imports for
useContextanduseMemo. This prevents webpack from statically resolvingReact.usewhile preserving existing React 19 behavior.No public API, runtime behavior, or peer dependency changes.
Testing
Verified with the repo's CRA 5 / React 18.3.1 example:
@auth0/auth0-react@2.24.0→ build fails withAttempted import error: 'use' is not exported from 'react'Summary by CodeRabbit
