If you're using @edx/frontend-build, then you'll get this package for free. Otherwise, you can install it via:
npx install-peerdeps --dev @edx/eslint-configThis will install the package and all of its peer dependencies.
Then, once it's installed, create an .eslintrc.js file in the top-level directory of your project with the following contents:
module.exports = {
extends: "@edx/eslint-config",
}If @edx/eslint-config detects a tsconfig.json file in the root folder of your project, it will optionally configure ESLint to add support for TypeScript. If a tsconfig.json file exists, the ESLint config will:
- Extend
airbnb-typescript(source). - Configure
parserOptions.projectto point to thetsconfig.jsonfile in the root folder of your project.
airbnb-typescript may only be extended if a tsconfig.json file exists in your project.
If your tsconfig.json file is defined somewhere other than the root folder of your project, you may override the default ESLint configuration by extending airbnb-typescript and including the path to your tsconfig.json file in the parserOptions.project ESLint configuration.
