opine-scripts

This module compiles javascript through browserify.

Installation:

yarn add gulp gulp-opine opine-scripts

Configuration:

Reminder: with opine you can run gulp config-defaults to print out the current values of all configuration values that haven't been explicitly defined.

• opine.scripts.source: the directory containing the entry file. Any file being changed in this directory or its children will trigger a rebuild.
• opine.scripts.entry: the name of the entry file.
• opine.scripts.dest: the directory to save the output .js file
• opine.scripts.target: the filename of the compiled .js file in the destination directory

Note that the filesystem watch functionality just monitors for any modification of any file in the source tree rather than intelligently monitoring files that have been required. Originally this module was written to use watchify but we encountered issues with linux incompatibility and decided to switch this module over to use the same watch as the rest of the opine ecosystem.

Multiple entry points and targets

The basic setup above accounts for a single entry point that bundles down to a single script. If you need multiple entry points, the following configuration will override the entry and target configuration values.

opine: {
    scripts: {
        multibundle: [ 
            { entry: 'form-entry.js', target: 'forms.js' },
            'main.js'   // equivalent to { entry: 'main.js', target: 'main.js' }
        ]
    }
}

Babelify

If you want to apply Babelify transforms, configure opine.scripts.transforms to be an array of the names of the presets you want to apply.

opine: {
    scripts: {
        transforms: ['es2015']
    }
}

Note that Babelify and its presets are NOT included as dependencies of opine-scripts; you will need to install them yourself (for the example above, you'd need to add the babelify and babel-preset-es2015 packages to your project).
