 : When enabled, a file named `hugo_stats.json` will be written to your project root with some aggregated data about the build, e.g. list of HTML entities published to be used to do [CSS pruning](/hugo-pipes/postprocess/#css-purging-with-postcss). If you're only using this for the production build, you should consider placing it below [config/production](/getting-started/configuration/#configuration-directory). It's also worth mentioning that, due to the nature of the partial server builds, new HTML entities will be added when you add or change them while the server is running, but the old values will not be removed until you restart the server or run a regular `hugo` build.

+{{< new-in "0.78.0" >}}
+
+Since Hugo `v0.78.0` `js.Build` has full support for the virtual union file system in [Hugo Modules](/hugo-modules/). You can see some simple examples in this [test project](https://github.com/gohugoio/hugoTestProjectJSModImports), but in short this means that you can do this:
+
+```js
+import { hello } from 'my/module';
+```
+
+And it will respolve to the top-most `index.{js,ts,tsx,jsx}` inside `assets/my/module` in the layered file system.
+
+```js
+import { hello3 } from 'my/module/hello3';
+```
+
+Wil resolve to `hello3.{js,ts,tsx,jsx}` inside `assets/my/module`.
+
+Any imports starting with `.` is resolved relative to the current file:
+
+```js
+import { hello4 } from './lib';
+```
+
+For other files (e.g. `JSON`, `CSS`) you need to use the relative path including any extension, e.g:
+
+```js
+import * as data from 'my/module/data.json';
+```
+
+Also note the new `params` option that can be passed from template to your JS files, e.g.:
+
+```go-html-template
+{{ $js := resources.Get "js/main.js" | js.Build (dict "params" (dict "api" "https://example.org/api" ) }}
+```
+And then in your JS file: 
+
+```js
+import * as params from '@params';
+```
+
+Hugo will, by default, generate a `assets/jsconfig.js` file that maps the imports. This is useful for navigation/intellisense help inside code editors, but if you don't need/want it, you can [turn it off](/getting-started/configuration/#configure-build).

-#### Shimming a JS library
+#### Shimming a JS library 
+
 It's a very common practice to load external libraries using CDN rather than importing all packages in a single JS file, making it bulky. To do the same with Hugo, you'll need to shim the libraries as follows. In this example, `algoliasearch` and `instantsearch.js` will be shimmed.
 
 Firstly, add the following to your project's `package.json`:
