    PostCSS

    PostCSS

    A tool for transforming CSS with JavaScript

    PostCSS is a tool for transforming styles with JS plugins. These plugins can do a great number of things: transpile future CSS syntax, lint your CSS, support variables and mixins, and so much more. PostCSS works by taking a CSS file and providing an API to analyze and modify its rules (through its transformation into an Abstract Syntax Tree). The API can then be used by plugins to do a lot of useful things. With PostCSS, you can increase code readability by adding vendor prefixes to CSS rules; convert modern CSS so it's understood by more browsers; and avoid errors in your CSS via stylelint, a modern CSS linter. PostCSS currently has over 200 plugins, and is being used by industry leaders worldwide.

    browserify

    browserify

    browser-side require() the node.js way

    Browserify lets you require('modules') in the browser by bundling up all of your dependencies. Browsers don't have the require method defined, but Node.js does. With Browserify you can write code that uses require in the same way that you would use it in Node. Install the uniq module with npm. Now recursively bundle up all the required modules starting at main.js into a single file called bundle.js with the browserify command. Browserify parses the AST for require() calls to traverse the entire dependency graph of your project. Drop a single <script> tag into your html and you're done! browserify is a tool for compiling node-flavored commonjs modules for the browser. You can use browserify to organize your code and use third-party libraries even if you don't use node itself in any other capacity except for bundling and installing packages with npm.
