Babel Inline Import Data URI

Babel plugin to add the opportunity to use import file content as DataURI.

Examples

// server.js
import logo from './logo.svg';

// Will print "data:image/svg+xml;base64,PD94bWwgdmVyc2lv...4KPC9zdmc+';"
console.log(logo);

Install

npm install babel-plugin-inline-import-data-uri --save-dev

Use

Add a .babelrc file and write:

{
  "plugins": [
    "inline-import-data-uri"
  ]
}

or pass the plugin with the plugins-flag on CLI

babel-node myfile.js --plugins inline-import-data-uri

By default, Babel-Inline-Import is compatible with the following file extensions:

• .svg
• .png

Customize

If you want to enable different file extensions, you can define them in your .babelrc file

{
  "plugins": [
    ["babel-plugin-inline-import", {
      "extensions": [
        ".html",
        ".jpg"
      ]
    }]
  ]
}

How it works

It inserts the content of the imported file directly into the importing file encoded as Data URI, assigning it to a variable with the same identifier of the import statement, thus replacing the import statement and the file path by its resulting content.

Caveats

Babel does not track dependency between imported and importing files after the transformation is made. Therefore, you need to change the importing file in order to see your changes in the imported file spread. To overcome this:

• If you are using babel-node or babel-register, you can disable babel cache (BABEL_DISABLE_CACHE=1).
• If you are using webpack with babel-loader, you can use babel-inline-import-loader.

Also make sure that your task runner is watching for changes in the imported file as well. You can see it working here.
