esi-include-plugin

General plugin logic for esi:include script or source injection

What is it?

This generic "plugin" is to handle esi:include injection based on configuration. There are two main "modes" in which this utility will replace tags in html.

• Production Mode: The plugin will replace the html tags with the correctly configured esi:include tag.
• Local or Dev Mode: Here lies the great strength of this plugin. When running in a local or dev mode the plugin will fetch the configured remote src and inject the contents in place of the tag, effectively emulating the esi:include logic.

How to use it?

Use a script like the following example and call it as part of an npm script. "start": ""

(async function esiIncludeScript(){
  const esiIncludeModule = require('@meltwater/esi-include-plugin');

await esiIncludeModule({
  files: ['dist/index.hmtl'],
  verbose: false,
  esi: [
    {name: 'includeThing', src: 'http://myincludeurl.com/asset', noStore: true, onError: 'continue', authorization: 'ImAFakeToken', maxwait: '500'},
  ]
});
})();

In your html place the following comment tag where you'd like the injection to take place

<!--esi-include-webpack-plugin name=includeThing-->

A more advanced example that can handle more fun stuff like specifying files and handling different source file urls based on a stage.

(async function esiIncludeScript(){
  const esiIncludeModule = require('@meltwater/esi-include-plugin');
  const argv = require('yargs').argv;

  let config = argv.stage === 'prod' ?
  {
    includeThing: 'https://mystagingurl.com/asset'
  } : {
    includeThing: 'https://myprodurl.com/asset'
  }

  if(argv.files) {
    config.files = argv.files.split(',')
  } else {
    config.files = ['./src/index.html']
  }

await esiIncludeModule({
  files: config.files,
  verbose: false,
  esi: [
    {name: 'includeThing', src: config.includeThing, noStore: true, onError: 'continue', authorization: 'ImAFakeToken', maxwait: '500'},
  ]
});
})();
