v4.0.0

Breaking changes

• Minimum support is now Node 10+, please use datauri 3 for previous versions.

• CSS

  • rename class config to className

  • rename background-size config to backgroundSize

  • Isolate getCSS in datauri/css submodule

    Before (getCSS function)

    const datauri = require('datauri');
     
    datauri('test/myfile.png', (err, content, meta) => {
     meta.getCSS({
        class: "myClass",
        'background-size': true,
        width: true,
        height: true
      }));
    });

    After (datauri/css)

    const datauriCSS = require('datauri/css');
    
    await datauriCSS('test/myfile.png', {
      className: "myClass",
      backgroundSize: true,
      width: true,
      height: true
    });

• CLI

  • fs promises instead of Sync function

  • background-size flag renamed to backgroundSize

  • class flag renamed to className

    Before

    datauri brand.png --css --class=MyNewClass --background-size

    After

    datauri brand.png --css --className=MyNewClass --backgroundSize

Dev experience

• Migrate TravisCI to Github actions
• create devcontainer file for Github Codespaces
• format code with prettier
• master branch renamed to main

Performance tweaks

• CSS parser runs a single fs read operation
• datauri parser by default do not use any external dependencies because image-size is now isolated in datauri/css submodule.
• uses Node.js fs native promises instead of factoring it with utils
