Plural's Javascript Styleguide {

🎨 How plural paints its code;

Getting Started

Our default export contains all of our ESLint rules, including ECMAScript 6+ and React. It requires eslint, eslint-plugin-import, eslint-plugin-react, eslint-plugin-react-hooks, eslint-plugin-react-hooks-docs, eslint-plugin-jsx-a11y and eslint-plugin-react-perf. If you don't need React, see base entry point.

If using yarn, you can also use the shortcut described above if you have npm 5+ installed on your machine, as the command will detect that you are using yarn and will act accordingly. Otherwise, run npm info "eslint-config-plural@latest" peerDependencies to list the peer dependencies and versions, then run yarn add --dev @ for each listed peer dependency.

1. Install the correct versions of each package, which are listed by the command:

npm info "eslint-config-plural@latest" peerDependencies

If using npm 5+, use this shortcut

npx install-peerdeps --dev eslint-config-plural

If using npm < 5, Linux/OSX users can run

(
  export PKG=eslint-config-plural;
  npm info "$PKG@latest" peerDependencies --json | command sed 's/[\{\},]//g ; s/: /@/g' | xargs npm install --save-dev "$PKG@latest"
)

Which produces and runs a command like:

npm install --save-dev eslint-config-plural eslint@^#.#.# eslint-plugin-jsx-a11y@^#.#.# eslint-plugin-import@^#.#.# eslint-plugin-react@^#.#.#

If using npm < 5, Windows users can either install all the peer dependencies manually, or use the install-peerdeps cli tool.

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

The cli will produce and run a command like:

npm install --save-dev eslint-config-plural eslint@^#.#.# eslint-plugin-jsx-a11y@^#.#.# eslint-plugin-import@^#.#.# eslint-plugin-react@^#.#.#

2. Add "extends": "plural" to your .eslintrc

Base entry point

Our default export contains all of our ESLint rules, including ECMAScript 6+ without React. It requires eslint and eslint-plugin-import.

1. follow the steps above
2. Add "extends": "plural/base" to your .eslintrc

Typescript

To extend Typescript configuration you should extend the .tsconfig.json file in your tsconfig.json.

{
  "extends": "./node_modules/eslint-config-plural/tsconfig",
  "compilerOptions": {
    "strictNullChecks": false
  }
}

Parents:

eslint-config-plural extends eslint-config-airbnb or eslint-config-airbnb-base style guide, appending our rules.

Changelog

Check the changelog for version details.

Improving this config

Consider adding test cases if you're making complicated rules changes, like anything involving regexes. Perhaps in a distant future, we could use literate programming to structure our README as test cases for our .eslintrc?

You can run tests with npm test.

You can make sure this module lints with itself using npm run lint.
