    'extensions': ['.jsx'],
    'options': {
        'plugins': ['transform-import-cssm'],
        "presets": ["react"],
        "generatorOpts": {
            "jsescOption": {

You can customize by provide BABEL_TRANSPILING in your django settings, for example, custom babel preset:

BABEL_TRANSPILING = {
    'options': {
        "filename": "index.ts",
        "presets": ["typescript"]
    }
}

Babel API

You can control more by set setup option, for example, write custom plugin and register:

$ cat path/to/setup.js

// Simple plugin that converts every identifier to "LOL"
function lolizer() {
  return {
    visitor: {
      Identifier(path) {
        path.node.name = 'LOL';
      }
    }
  }
}
Babel.registerPlugin('lolizer', lolizer);

Then config options:

BABEL_TRANSPILING = {
    'options': {
        'plugins': ['lolizer']
    },
    'setup': ['path/to/setup.js']
}

Template Support

Sometimes transpiling in your template file is more make sense than static file, you can use transpiling tag to do that.

{% load babel_transpiling %}
...
<script>
    {% transpiling %}
      ReactDOM.render(<App/>, document.querySelector('#root'))
    {% endtranspiling %}
</script> 
...

Template tag also support use custom transpiling option, for example, in context there exists a ts option:

{% transpiling options=ts %}
  const anExampleVariable: string = "Hello World"
  console.log(anExampleVariable)
{% endtranspiling %}
