Setup

1) Configure ESLint

Extend your .eslintrc, with react-moonstone.

{
  "extends": ["react-moonstone"]
}

Or if you have another config, you can set it like this,

{
  "extends": ["react-moonstone", "next/core-web-vitals"]
}

The order of the array items depends on your needs.

Read more about ESLint configuration file.

2) Configure the ESLint TypeScript parser

• Set parser to @typescript-eslint/parser.
• Set parserOptions.project to the path of your tsconfig.json or tsconfig.eslint.json (see FAQ below).

For example:

{
  "extends": ["react-moonstone"],
+ "parser": "@typescript-eslint/parser",
+ "parserOptions": {
+   "project": "./tsconfig.json"
+ }
}

FAQ

If you got this error when running ESLint: "The file must be included in at least one of the projects provided", this means you are attempting to lint a file that tsconfig.json doesn't include.

A common fix is to create a tsconfig.eslint.json file, which extends your tsconfig.json file and includes all files you are linting.

{
  "extends": "./tsconfig.json",
  "include": ["**/*.ts", "**/*.tsx", "**/*.js", ".eslintrc.js"]
}

Then update your ESLint config file:

"parserOptions": {
-  "project": "./tsconfig.json"
+  "project": "./tsconfig.eslint.json"
}
