Any JavaScript resource file can be transpiled to another JavaScript version using `resources.Babel` which takes for argument the resource object and an optional dict of options listed below. Babel uses the [babel cli](https://babeljs.io/docs/en/babel-cli).
|

{{% note %}}
|
|
Hugo Pipe's Babel requires the `@babel/cli` and `@babel/core` JavaScript packages to be installed in the project or globally (`npm install -g @babel/cli @babel/core`) along with any Babel plugin(s) or preset(s) used (e.g., `npm install @babel/preset-env --save-dev`).
|
|
|
|
If you are using the Hugo Snap package, Babel and plugin(s) need to be installed locally within your Hugo site directory, e.g., `npm install @babel/cli @babel/core --save-dev` without the `-g` flag.

### Config
|
|
|
|
{{< new-in "v0.75.0" >}}
|
|
|
|
In Hugo `v0.75` we improved the way we resolve JS configuration and dependencies. One of them is that we now add the main project's `node_modules` to `NODE_PATH` when running Babel and similar tools. There are some known [issues](https://github.com/babel/babel/issues/5618) with Babel in this area, so if you have a `babel.config.js` living in a Hugo Module (and not in the project itself), we recommend using `require` to load the presets/plugins, e.g.:
|
|
|
|
|
|
```js
|
|
module.exports = {
|
|
presets: [
|
|
[
|
|
require('@babel/preset-env'),
|
|
{
|
|
useBuiltIns: 'entry',
|
|
corejs: 3
|
|
}
|
|
]
|
|
]
|
|
};
|
|
```
|
|
|
|
|
|
|
|
### Options
|
|
|
|
config [string]
|
|
: Path to the Babel configuration file. Hugo will, by default, look for a `babel.config.js` in your project. More information on these configuration files can be found here: [babel configuration](https://babeljs.io/docs/en/configuration).
|
|
|
|
minified [bool]
|
|
: Save as much bytes as possible when printing
|
|
|
|
noComments [bool]
|
|
: Write comments to generated output (true by default)
|
|
|
|
compact [bool]
|
|
: Do not include superfluous whitespace characters and line terminators. Defaults to `auto` if not set.
|
|
|
|
verbose [bool]
|
|
: Log everything
|
|
|
|
### Examples
|
|
|
|
```go-html-template
|
|
{{- $transpiled := resources.Get "scripts/main.js" | babel -}}
|
|
```
|
|
|
|
Or with options:
|
|
|
|
```go-html-template
|
|
{{ $opts := dict "noComments" true }}
|
|
{{- $transpiled := resources.Get "scripts/main.js" | babel $opts -}}
|
|
```
