This package provides pro!vision's ESLint configuration as an extensible shared config.

Inspired by Airbnb

Versions

This is version >= 2.0.0 of eslint-config-pv, which is compatible with eslint >= 4.0.0. I you are using eslint 3, use eslint-config-pv 1.0.10

Installation

npm install --save-dev eslint-config-pv eslint-plugin-import
# for the eslint 3 compatible version
npm install --save-dev eslint-config-pv@1.0.10 eslint-plugin-import

Usage

We export four ESLint configurations for usage in projects.

eslint-config-pv

Our default export contains all of our ESLint rules, including ECMAScript 6 / ES2015. Add "extends": "pv" to your .eslintrc:

{
  "extends": "pv",
  "rules": {
    // additional rules here
  },
  "env": {
    // ... add more environments
  }
}

eslint-config-pv/legacy

Use the legacy sub package if you only want to lint ES5 and below.

{
  "extends": "pv/legacy",
  "rules": {
    // additional rules here
  }
}

eslint-config-pv/prettier

You need to install additional plugins:

npm install --save-dev eslint-config-prettier eslint-plugin-prettier prettier

This allows you to use prettier with eslint integration

{
  "extends": "pv/prettier"
}

See the ESlint config docs for more information.

eslint-config-pv/typescript

You need to install additional @typescript-eslint plugins (>=v2.19):

npm install --save-dev @typescript-eslint/parser  @typescript-eslint/eslint-plugin

This allows you to eslint your tylescript files

{
  "extends": [
    "pv/typescript",
    // "pv/prettier" // in case you are using prettier as well
  ]
}

pv/prettier assumes your tsconfig.json file is in the same directory as where you call eslint. For example your projects root directory. But you can also specify this with:

{
  "extends": [
    "pv/typescript",
  ]
  parserOptions: {
    project: "./my-tsconfig.json",
    tsconfigRootDir: "my-configs/",
  },
}

WebStorm Integration

Ensure you are using node >= 4.5 and you have installed eslint and eslint-plugin-import globally:

# node version should be at least 4.5
node -v

# install necessary modules globally
npm install -g eslint eslint-plugin-import

Now you can follow the instructions here

Keep in mind that WebStorm pass all JavaScript files (starting from project root) to eslint. To prevent directories from being linted, mark them as Excluded. Go to project structure and right click on the directory to be excluded -> Mark Directory as -> Excluded. Special directories, such as node_modules are marked automatically as library root and will be excluded by default.

Alternatively, you can define .eslintignore as described here.
