Build Status JavaScript Style Guide npm

An ESLint shareable config for TypeScript that is based on eslint-config-standard and has TypeScript specific rules from @typescript-eslint/eslint-plugin.

Peer dependencies

This package specifies the following peerDependencies:

Yes, this is a large number of peerDependencies. This is due to a known limitation in ESLint.

@typescript-eslint dependencies

This package has @typescript-eslint/parser in dependencies.
And it has @typescript-eslint/eslint-plugin in peerDependencies.
Both are specified as ranges. It's probably safest for the installed versions of these packages to be the same. This can be achieved by:

  1. Pin (exact version) the @typescript-eslint/eslint-plugin in package.json.
  2. Have a package-lock.json which locks the version of the @typescript-eslint/parser sub-dependency.

And both pin/lock to the same version.


Yarn does not automatically install peerDependencies, so if that's what you're using, install them manually. Here is an example, but use it only for reference, because your decisions regarding version ranges and range specifiers may vary.

yarn add --dev \
  typescript@\* \
  eslint@^8.0.1 \
  eslint-plugin-promise@^6.0.0 \
  eslint-plugin-import@^2.25.2 \
  eslint-plugin-n@^15.0.0 \
  @typescript-eslint/eslint-plugin@^6.4.0 \

Example config

Here is an example .eslintrc.js. Pay close attention to the files property, because it determines which files are linted.

module.exports = {
  overrides: [
      files: ['*.js', '*.jsx', '*.ts', '*.tsx'],
      extends: 'standard-with-typescript'

Note: the config exported by this package sets parserOptions.project = true. Read about the project option here.

There are some more parserOptions you may care about.

Example command line usage:

$ npx eslint .
