The Lune Climate shared ESLint configuration

Developing the shared configuration

• Follow https://eslint.org/docs/latest/extend/shareable-configs
• No need to publish to NPM, the configuration can be fetched via Git

Using the configuration in a project

1. Add the @lune-climate/eslint-config dependency to your project

yarn add --dev git+https://github.com/lune-climate/eslint-config.git#master

2. Make sure your package.json is in the right shape.

   • The dependencies that our eslint-config declares should not be present in your package.json.
   • You have to provide the peerDependencies that we expect.

3. Adapt your .eslintrc or equivalent:

   a. Remove configuration that is already provided by this shared configuration. b. One exception to the above is parser and parserOptions. You need to define them, for example:

   parser: "@typescript-eslint/parser",
   parserOptions: {
       ecmaVersion: 12,
       sourceType: "module",
   
       // These are needed for some of the typescript-eslint type-based linting rules like
       // no-unnecessary-condition.
       "tsconfigRootDir": __dirname,
       "project": ["./tsconfig.json"],
   },
   

   c. Add @lune-climate to extends, like:

   extends: ["@lune-climate"],
