What's CSS Linting and Style Enforcement?

CSS Linting and Style Enforcement tools help developers maintain consistent coding styles and catch potential errors in their stylesheets. These tools analyze CSS (Cascading Style Sheets) code for issues such as syntax errors, inefficient selectors, and violations of best practices. By integrating linting into the development workflow, teams can ensure that their stylesheets are clean, efficient, and adhere to predefined coding standards, ultimately improving code quality and maintainability. stylelint is a modern, flexible, and highly configurable linter for CSS, SCSS, and other style files, while sass-lint is specifically designed for linting SASS and SCSS files, focusing on SASS-specific syntax and best practices.

Feature Comparison: stylelint vs sass-lint

Language Support

  • stylelint:

    stylelint supports a broad range of CSS syntaxes, including traditional CSS, SASS, LESS, and Stylus. This makes it a more versatile choice for projects that may use multiple styling languages or preprocessors.

  • sass-lint:

    sass-lint is tailored for SASS and SCSS, providing rules and checks specifically for these syntaxes. It is best suited for projects that exclusively use SASS/SCSS and need focused linting on SASS-specific features.

Configurability

  • stylelint:

    stylelint is highly configurable and supports a wide range of customization options. It allows users to create their own rules, use community-contributed plugins, and configure the linter to suit various coding standards and team preferences.

  • sass-lint:

    sass-lint offers a decent level of configurability, allowing users to enable or disable specific rules and customize the configuration file. However, it is more limited compared to stylelint in terms of extensibility and adding custom rules.

Plugin Ecosystem

  • stylelint:

    stylelint boasts a rich ecosystem of plugins and integrations, allowing users to extend its functionality significantly. There are plugins available for various tasks, including accessibility checks, performance optimization, and more.

  • sass-lint:

    sass-lint has a smaller plugin ecosystem, primarily focused on SASS and SCSS. While it supports some level of customization, it does not have the same breadth of third-party plugins as stylelint.

Integration with Build Tools

  • stylelint:

    stylelint offers seamless integration with a wide range of build tools, CI/CD pipelines, and code editors. Its flexibility and extensive documentation make it easy to incorporate into any workflow.

  • sass-lint:

    sass-lint can be integrated into build processes using tools like Gulp, Grunt, and Webpack. However, its integration capabilities are more limited compared to stylelint, which has broader support across various tools and platforms.

Community and Maintenance

  • stylelint:

    stylelint has a large and active community, ensuring regular updates, bug fixes, and the introduction of new features. Its popularity and widespread use in the industry contribute to its reliability and longevity.

  • sass-lint:

    sass-lint is maintained by a smaller community, and while it receives updates, it is not as actively developed as stylelint. This may impact its long-term viability and support for new features.

Ease of Use: Code Examples

  • sass-lint:

    sass-lint Example

    {
  "files": ["**/*.scss"],
  "options": {
    "config": "sass-lint.yml"
  }
}

    stylelint Example

    {
  "extends": "stylelint-config-standard",
  "rules": {
    "color-no-invalid-hex": true
  }
}
How to Choose: stylelint vs sass-lint
  • stylelint:

    Choose stylelint if you need a versatile and highly configurable linter that supports a wide range of CSS preprocessors, including SASS, LESS, and Stylus. It is suitable for projects with diverse styling approaches and offers extensive plugin support for customization.

  • sass-lint:

    Choose sass-lint if you are working primarily with SASS or SCSS files and need a linter that focuses on SASS-specific syntax and conventions. It is ideal for projects that heavily utilize SASS features and require strict adherence to SASS coding standards.

Similar Npm Packages to stylelint

stylelint is a powerful, modern linter for CSS and its preprocessors, such as SCSS and Less. It helps developers maintain consistent coding styles and catch errors in their stylesheets before they become problematic. By enforcing coding standards and best practices, stylelint improves the quality of CSS code, making it easier to read and maintain. While stylelint is a robust tool for CSS linting, there are other alternatives in the ecosystem that serve different purposes. Here are a few notable alternatives:

  • eslint is a widely-used linter for JavaScript and JSX code. It helps developers identify and fix problems in their JavaScript code by enforcing coding standards and best practices. While eslint is primarily focused on JavaScript, it can be extended to lint other file types, including styles written in CSS-in-JS libraries. If you're looking for a comprehensive solution for linting both JavaScript and CSS-in-JS styles, eslint is a great choice.
  • prettier is an opinionated code formatter that supports multiple languages, including JavaScript, CSS, and HTML. Unlike traditional linters, which focus on identifying potential issues in the code, prettier automatically formats code according to a set of rules. This ensures a consistent code style across your project without requiring manual adjustments. While prettier doesn't replace stylelint, it can be used alongside it to ensure both linting and formatting of CSS and other code types.
  • sass-lint is a linter specifically designed for Sass (Syntactically Awesome Style Sheets). It helps enforce coding standards and best practices in Sass files, similar to what stylelint does for CSS. If your project primarily uses Sass and you want a linter tailored specifically for that preprocessor, sass-lint is a suitable alternative.

Similar Npm Packages to sass-lint

sass-lint is a powerful linting tool specifically designed for Sass (Syntactically Awesome Style Sheets) files. It helps developers maintain consistent coding styles and catch potential errors in their Sass code before it reaches production. By enforcing best practices and coding standards, sass-lint can improve the overall quality and maintainability of stylesheets in a project. It provides a range of configurable rules that can be tailored to fit the needs of different projects, making it a versatile choice for teams working with Sass.

One notable alternative to sass-lint is stylelint. While sass-lint is focused specifically on Sass, stylelint is a more general-purpose linter for CSS and its preprocessors, including Sass. It offers a comprehensive set of rules and plugins that can be customized to enforce coding standards across various stylesheets. stylelint is widely adopted in the web development community and is known for its flexibility and extensibility. If you are looking for a linter that can handle multiple CSS preprocessors and provide robust linting capabilities, stylelint is an excellent choice.

README for stylelint

Stylelint

npm version Build Status npm downloads

A mighty CSS linter that helps you avoid errors and enforce conventions.

Features

It's mighty as it:

  • has over 100 built-in rules for modern CSS syntax and features
  • supports plugins so you can create your own custom rules
  • automatically fixes problems where possible
  • supports shareable configs that you can create or extend
  • can be customized to your exact needs
  • has 15k unit tests making it robust
  • is trusted by companies worldwide like Google and GitHub

And it can be extended to:

  • extract embedded styles from HTML, Markdown and CSS-in-JS template literals
  • parse CSS-like languages like SCSS, Sass, Less and SugarSS

How it'll help you

It'll help you avoid errors, for example:

  • invalid things, e.g. malformed grid areas
  • valid things that are problematic, e.g. duplicate selectors
  • unknown things, e.g. misspelled property names

And enforce conventions, for example:

  • disallow things, e.g. specific units
  • enforce naming patterns, e.g. for custom properties
  • set limits, e.g. the number of ID selectors
  • specify notations, e.g. for modern color functions

We recommend using a pretty printer like Prettier alongside Stylelint. Linters and pretty printers are complementary tools that work together to help you write consistent and error-free code.
