How to Fix the eslint failed to load config 'react-app' Error in Your React Project

If you're working on a React project and come across the error message eslint failed to load config 'react-app', you're not alone. This issue typically arises from problems with the ESLint configuration in projects created with Create React App (CRA). In this guide, we'll explore why this error occurs and how you can fix it.

What Causes the Error?

The error usually occurs when ESLint is unable to find or properly load the "react-app" configuration that is meant to be extended from. This configuration is part of the Create React App setup and is supposed to help standardize the linting process across React projects.

Solutions to Fix the Error

Ensure Relevant Packages Are Installed

The first step is to make sure that all required packages are correctly installed in your project. Open your package.json file and verify that eslint-config-react-app, eslint, and eslint-plugin-react are listed among your dependencies or devDependencies:

If any of these packages are missing, you can install them using npm or yarn:

Verify .eslintrc Configuration

Open your .eslintrc file or ESLint configuration in your package.json and make sure that the configuration extends from "react-app":

This tells ESLint to use the rules and settings provided by Create React App.

Update Dependencies

Sometimes, the issue may stem from outdated dependencies. Running npm update or yarn upgrade will ensure all packages are at their latest versions:

Use Create React App to Eject (Optional)

If none of the above solutions work, an alternative approach is to eject the Create React App configuration. This will give you full control over the configuration files but also adds complexity to your project. Run the following command:
