eslint-plugin-typescript

LifeOmic config for typescript-eslint

Installation

Next, install @lifeomic/eslint-plugin-typescript:

yarn add -D @lifeomic/eslint-plugin-typescript --save-dev

Usage

Add typescript to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
  plugins: ['@lifeomic/typescript'];
}

Add the recommended config and rules to your extends:

{
    extends: ['plugin:@lifeomic/typescript/recommended']
}

There's an optional reactNative config which provides some helpers for reactNative.

NOTE: These make use of the @typescript-eslint/eslint-plugin-tslint plugin, which does not like to be run on non-typescript files, or files not included in a project. That means if you have js files, or ts files outside of a helper included in your lint config, you can do something like this:

const lifeomicTypescript = require('@lifeomic/eslint-plugin-typescript');
const reactNative = lifeomicTypescript.configs.reactNative;
