npm add --save-dev @iadvize-oss/eslint-config eslint

Usage

Create a .eslintrc file in your project root with this content

{
  "extends": [
    "@iadvize-oss/eslint-config",
    // or
    "@iadvize-oss/eslint-config/one-config"
  ]
}

Which config ?

The package provide multiple configs whether you need simple javascript linting of full typescript + javascript + react linting with type-aware rules.

The details are here:

config	javascript	react	typescript	with types
@iadvize-oss/eslint-config/javascript	✔️
@iadvize-oss/eslint-config/javascript-react	✔️	✔️
@iadvize-oss/eslint-config/light-typescript	✔️		✔️
@iadvize-oss/eslint-config/light-typescript-react	✔️	✔️	✔️
@iadvize-oss/eslint-config/typescript	✔️		✔️	✔️
@iadvize-oss/eslint-config/typescript-react	✔️	✔️	✔️	✔️

The @iadvize-oss/eslint-config links to @iadvize-oss/eslint-config/typescript-react.

Note that all configs can be used on JSON files too.

Typescript

You will need to install a peer-dependency @typescript-eslint/parser as it is required by eslint-plugin-import internally.

We lint typescript files with @typescript-eslint/eslint-plugin that provide rules that replace default eslint ones.

Some of these rules are type-aware and use tsc under the hood to compile each file before lint.

As this can drastically affect performance for big code base, we provide light-typescript configs that do not use type-aware rules.

If you decide to give @iadvize-oss/eslint-config/typescript or @iadvize-oss/eslint-config/typescript-react a try, you will need a tsconfig.json file at the root of your project for type-aware rules to work.

Because we also lint JSON files, you need to include them like so:

  "include": [
    "**/*",
    "**/*.json"
  ],
  "exclude": ["node_modules"]

It's probably better for you to define one special .eslint.tsconfig.json like so:

{
  "extends": "./tsconfig.json",
  "compilerOptions": {
    "noEmit": true
  },
  "include": [
    "**/*",
    "**/*.json"
  ]
}

Then, in you .eslintrc

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

Special eslint patch

The lib also provide a workaround for https://github.com/eslint/eslint/issues/3458

When needed, start by requiring the patch in your config entry point.

require('@iadvize-oss/eslint-config/patch');

module.exports = {
  extends: [
    'eslint-config-airbnb-base',
    ...
