Babel

Hugo Pipes can process JS files with Babel.

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.

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

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 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.:

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.
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

{{- $transpiled := resources.Get "scripts/main.js" | babel  -}}

Or with options:

{{ $opts := dict "noComments" true }}
{{- $transpiled := resources.Get "scripts/main.js" | babel $opts -}}
