Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

PostCSS plugin to import CSS files

Downloads

Readme

  • Remove this rule: This plugin attempts to follow the CSS @import spec; @import statements must precede all other statements (besides @charset).

postcss-import

Unix Build status Windows Build status Version Greenkeeper badge

PostCSS plugin to transform @import rules by inlining content.

This plugin can consume local files, node modules or web_modules. To resolve path of an @import rule, it can look into root directory (by default process.cwd()), web_modules, node_modules or local modules. When importing a module, it will look for index.css or file referenced in package.json in the style or main fields. You can also provide manually multiples paths where to look at.

Notes:

  • This plugin should probably be used as the first plugin of your list. This way, other plugins will work on the AST as if there were only a single file to process, and will probably work as you can expect.
  • This plugin works great with postcss-url plugin, which will allow you to adjust assets url() (or even inline them) after inlining imported files.
  • In order to optimize output, this plugin will only import a file once on a given scope (root, media query...). Tests are made from the path & the content of imported files (using a hash table). If this behavior is not what you want, look at skipDuplicates option
  • If you are looking for glob, or sass like imports (prefixed partials), please look at postcss-easy-import (which use this plugin under the hood).
  • Imports which are not modified (by options.filter or because they are remote imports) are moved to the top of the output.

Installation

$ npm install postcss-import

Usage

Unless your stylesheet is in the same place where you run postcss (process.cwd()), you will need to use from option to make relative imports work.

// dependencies
var fs = require("fs")
var postcss = require("postcss")
var atImport = require("postcss-import")

// css to be processed
var css = fs.readFileSync("css/input.css", "utf8")

// process css
postcss()
  .use(atImport())
  .process(css, {
    // `from` option is needed here
    from: "css/input.css"
  })
  .then(function (result) {
    var output = result.css

    console.log(output)
  })

css/input.css:

/* can consume `node_modules`, `web_modules` or local modules */
@import "cssrecipes-defaults"; /* == @import "../node_modules/cssrecipes-defaults/index.css"; */
@import "normalize.css"; /* == @import "../node_modules/normalize.css/normalize.css"; */

@import "foo.css"; /* relative to css/ according to `from` option above */

@import "bar.css" (min-width: 25em);

body {
  background: black;
}

will give you:

/* ... content of ../node_modules/cssrecipes-defaults/index.css */
/* ... content of ../node_modules/normalize.css/normalize.css */

/* ... content of css/foo.css */

@media (min-width: 25em) {
/* ... content of css/bar.css */
}

body {
  background: black;
}

Checkout the tests for more examples.

Options

filter

Type: Function Default: () => true

Only transform imports for which the test function returns true. Imports for which the test function returns false will be left as is. The function gets the path to import as an argument and should return a boolean.

root

Type: String Default: process.cwd() or dirname of the postcss from

Define the root where to resolve path (eg: place where node_modules are). Should not be used that much. Note: nested @import will additionally benefit of the relative dirname of imported files.

path

Type: String|Array Default: []

A string or an array of paths in where to look for files.

plugins

Type: Array Default: undefined

An array of plugins to be applied on each imported files.

resolve

Type: Function Default: null

You can provide a custom path resolver with this option. This function gets (id, basedir, importOptions) arguments and should return a path, an array of paths or a promise resolving to the path(s). If you do not return an absolute path, your path will be resolved to an absolute path using the default resolver. You can use resolve for this.

load

Type: Function Default: null

You can overwrite the default loading way by setting this option. This function gets (filename, importOptions) arguments and returns content or promised content.

skipDuplicates

Type: Boolean Default: true

By default, similar files (based on the same content) are being skipped. It's to optimize output and skip similar files like normalize.css for example. If this behavior is not what you want, just set this option to false to disable it.

addModulesDirectories

Type: Array Default: []

An array of folder names to add to Node's resolver. Values will be appended to the default resolve directories: ["node_modules", "web_modules"].

This option is only for adding additional directories to default resolver. If you provide your own resolver via the resolve configuration option above, then this value will be ignored.

Example with some options

var postcss = require("postcss")
var atImport = require("postcss-import")

postcss()
  .use(atImport({
    path: ["src/css"],
  }))
  .process(cssString)
  .then(function (result) {
    var css = result.css
  })

dependency Message Support

postcss-import adds a message to result.messages for each @import. Messages are in the following format:

{
  type: 'dependency',
  file: absoluteFilePath,
  parent: fileContainingTheImport
}

This is mainly for use by postcss runners that implement file watching.
