Usage

See configuring Bundles for how to configure Bundles and bundlers.

Configuration

The following properties are available in bundler.options:

• include {String[]|Function} (['.js', '.css']) Determines whether filepath should include a banner. If String Array matches the file extension, or if a Function returns true, a banner is added.
• prefix {String} ('/*! ') Banner prefix.
• suffix {String} (' */') Banner suffix.
• metadata {String[]|Array[]|Function|Function[]} (['author', 'reference']) Metadata to add to banner. Each item in the Array represents a parameter name, and the value of the parameter. Each item can be a String, an Array where item[0] is the parameter's name and item[1] is the value, or a Function which returns a String or Array. See example below.
• joinWith {String} (' | ') Character(s) to join metadata with.
• paramNameChar {String} ('@') Character(s) to prepend parameter name with.

Example

const bundle = {
    input: [...],
    bundlers: [{
        run: '@bundles/bundles-banner',
        include: ['.js'],
        // Metadata can be String, Array, or Function.
        metadata: ['author', ['my-param', 'This is my param.'], (file) => {
            if (file.data.myProp) return ['custom-param', 'Value is ' + file.data.myProp]
            return false
        }],
        joinWith: ' - '
    }]
}

Assuming the following data:

author: Snoopy
myProp: true

the above example will return:

/*! @author Snoopy - @my-param This is my param. - @custom-param Value is true */
