    Benchmark

    Benchmark: Async vs Neo-Async

    How to check

    $ git clone git@github.com:suguru03/async-benchmark.git
    $ cd async-benchmark
    $ npm install
    $ node . // It might take more than one hour...
    

    Environment

    Result

    Neo-Async is 1.27 ~ 10.7 times faster than Async.

    The value is the ratio (Neo-Async/Async) of the average speed.

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

    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.
