The plugin Bundler is disabled by default so to enable it you have to import and use it in the _config.js file:

import bundler from "lume/plugins/bundler.ts";


This plugin load .js and .ts files and output a single JavaScript file including all dependencies of the input. Internally uses the bundle Deno tool.

You can configure the bundler plugin with the following options:

Typescript for the browser

When bundling .ts files to run in the browser, use a triple slash reference to include helpful libraries, like dom in your scripts. For example,

/// <reference lib="dom" />


This will help Deno and your code editor to Bundle into JS appropriately.
