CSS Modules in Go

With this library you can parse any CSS that you have and get some key-value pairs with your classes and the scoped classes

• Features:

• Class scoping per function call

• Global scoping trought the :global keyword

• Media query scoping support

• Another @ (at) declarations support: @import, @font-face, @keyframes, etc.

• Your ID (#), element (div, span, etc.) and universal (*) selectors are global scoped whether they are outside or not of a :global block

• Scoping of animations (@keyframes declarations)

• Installation:

1. Create a new directory and initialize a go project with the following commands:

$ mkdir my-directory
$ cd my-directory
$ go mod init my-directory
go: creating new go.mod: module my-directory

1. Execute this command in your terminal and you are ready to go with CSS Modules:

$ go get github.com/otaxhu/go-cssmodules

• Quick usage:

package main

import (
    "log"
    "os"
    "strings"

    "github.com/otaxhu/go-cssmodules"
)

func main() {
    myCSS := strings.NewReader(
`.my-class {color: red;}`,
)
    // Now you have your cssScoped and you can access your classes throught 
    // the scopedClasses variable
    cssProcessed, scopedClasses, err := cssmodules.ProcessCSSModules(myCSS)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Printf("your css processed: %s\nmy-class generated name: %s", cssProcessed, scopedClasses["my-class"])
    // Output in Stdout will be something like this:
    //
    // your css processed: .RANDOMCLASS{color: red;}
    // my-class generated name: RANDOMCLASS
}
