Example

Given text.txt with the contents:

Hello, World!

the following JS:

let file = include("text.txt");

will be compiled to:

let file = "Hello, World!";

Information

• The file is included relative to the JS file the include is in unless a root is specified in the plugin options, in which case, the root is used. (See below for info on root)
• The default encoding is utf8 however that can be changed
• Special characters/unprintables are automatically escaped
• The include function takes a single string as argument. Any following arguments are ignored.

Options

babel-plugin-include allows you to change various settings by providing an options object by using the following instead:

{
    plugins: [
        ['include', { options }]
    ]
}

where { options } is the options object. The following options are available:

root

The root option specifies the root in which files are included from. e.g.:

{
    plugins: [
        ['include', {
            'root': 'proj/src'
        }]
    ]
}

encoding

The encoding option specifies which encoding to use when including files. Default is utf8

{
    plugins: [
        ['include', {
            'encoding': 'ucs2'
        }]
    ]
}

normalizeNewline

The normalize newline option specifies whether newlines should be normalized or not. This converts \r\n to \n and removes and trailing newlines. Disable this for binary files or other applicable locations.

{
    plugins: [
        ['include', {
            'encoding': 'ucs2'
        }]
    ]
}
