eslint-config-adjunct

eslint-config-adjunct

A mildly opinionated collection of the best lesser known esLint plugins to use alongside your main eslint configuration.

This config is designed to be used alongside any of the major esLint configs, such as airbnb or standard. It provides a range of extra rules to enhance the linting of your code.

Install

To run this config you will need to install it along with it's peerDependancies.

npx install-peerdeps --dev eslint-config-adjunct

If you have problems with the above command, then you will need to run install-peerdeps locally.

npm install -g install-peerdeps
install-peerdeps --dev eslint-config-adjunct

Configure

Extend your .eslintrc, with adjunct, which should be the last item in the extends array. For example if your using eslint-config-airbnb as your main rule set, your .eslintrc should look like this:

{
  "extends": ["airbnb", "adjunct"]
}

You can now include html and markdown in the list of files passed to esLint to have any contained JavaScript linted.

This configuration contains the following esLint plugins.

• eslint-plugin-array-func

Rules

Markdown

When linting code snippets in Markdown files, a few rules relating to globals and unused vars are disabled.

Switch-Case

Adds thes fallthrough: 'never' option to the the newlint-between-switch-case rule.

  case 1:
    something()
    break

  case 2:
