stylelint-webpack-plugin - A webpack plugin to lint your CSS/Sass code using stylelint

•    Javascript

---

This module requires a minimum of Node v6.9.0 and webpack v4.0.0. Both stylelint-loader and this module have their uses. stylelint-loader lints the files you require (or the ones you define as an entry in your webpack config). However, @imports in files are not followed, meaning only the main file for each require/entry is linted.

esprint - Fast eslint runner

•    Javascript

---

esprint (pronounced E-S-sprint) speeds up eslint by running the linting engine across multiple threads. esprint sets up a server daemon to cache the lint status of each file in memory. It uses a watcher to determine when files change, to only lint files as necessary. It also has a CI mode where it does not set up a daemon and just lints in parallel. esprint will find the root of your project automatically and lint the whole project. In default mode, esprint will start a background server to watch source files and cache lint results in memory.

stylelint-scss - A collection of SCSS specific linting rules for stylelint

•    Javascript

---

A collection of SCSS specific linting rules for stylelint (in a form of a plugin). stylelint by itself supports SCSS syntax very well (as well as other preprocessors' syntaxes). Moreover, it introduces some specific rules that can be used to lint SCSS, e.g. to limit nesting, control the way @-rules are written. Yet stylelint is in general focused on standard CSS.

---

"reviewdog" provides a way to post review comments to code hosting service, such as GitHub, automatically by integrating with any linter tools with ease.

puppet-lint - Check that your Puppet manifests conform to the style guide

•    Ruby

---

Puppet Lint tests Puppet code against the recommended Puppet language style guide. Puppet Lint validates only code style; it does not validate syntax. To test syntax, use Puppet's puppet parser validate command. Puppet Lint version 2 is the last planned version with support for Puppet 3 and Ruby 1.8.7. The next major version of Puppet Lint will drop support for these versions.

hadolint - Dockerfile linter, validate inline bash, written in Haskell

•    Haskell

---

A smarter Dockerfile linter that helps you build best practice Docker images. The linter is parsing the Dockerfile into an AST and performs rules on top of the AST. It is standing on the shoulders of ShellCheck to lint the Bash code inside RUN instructions. You can run hadolint locally to lint your Dockerfile.

eslint_d.js - Makes eslint the fastest linter on the planet

•    Javascript

---

Makes eslint the fastest linter on the planet.Yes, it's actually super fast. But the node.js startup time and loading all the required modules slows down linting times for a single file to ~700 milliseconds. eslint_d reduces this overhead by running a server in the background. It brings the linting time down to ~160 milliseconds. If you want to lint from within your editor whenever you save a file, eslint_d is for you.

JSXHint - Wrapper around JSHint for linting JSX files

•    Javascript

---

JSXHint is, and always was, a bad hack to make JSX lintable in the early days of React. It will always be inferior to proper linters like ESLint because it is not able to lint JSX or ES6 syntax, it instead compiles to ES5 then lints. You may get weird linter errors, especially with more involved transforms. Don't use JSXHint anymore if you can switch to ESLint.

prettier-eslint-cli - CLI for prettier-eslint

•    Javascript

---

You have a bunch of files that you want to format using prettier-eslint. But prettier-eslint can only operate on strings. This is a CLI that allows you to use prettier-eslint on one or multiple files. prettier-eslint-cli forwards on the filePath and other relevant options to prettier-eslint which identifies the applicable ESLint config for each file and uses that to determine the options for prettier and eslint --fix.
