rollup-plugin-iife
==================


Currently (rollup@0.65), rollup doesn't support code splitting with IIFE output. This plugin would transform ES module output into IIFEs.

Installation
------------

``
npm install -D rollup-plugin-iife
`

Usage
-----

`js
import iife from "rollup-plugin-iife";

export default {
input: ["entry.js", "entry2.js"],
output: {
dir: "dist",
format: "es",
globals: {
vue: "Vue"
}
},
externals: ["vue"],
plugins: [iife()]
};
`

Define global variables for external imports
--------------------------------------------

You can define global variables with output.globals just like before. You can also specify them with the plugin option names.

The plugin would first lookup names option then output.globals.

API
----

This module exports a single function.



$3



`js
iife({
names?: Function|Object,
sourcemap?: Boolean,
prefix?: String,
strict?: Boolean
}) => PluginInstance
`

Create the plugin instance.

If names is a function, the signature is:

`js
(moduleId: String) => globalVariableName: String
`

If names is an object, it is a moduleId/globalVariableName map. moduleId can be relative to the output folder (e.g. ./entry.js), the plugin would resolve it to the absolute path.

If the plugin can't find a proper variable name, it would generate one according to its filename with camelcase.

If sourcemap is false then don't generate the sourcemap. Default: true.

When prefix is defined, it will be used to prefix auto-generated variable names. It doesn't prefix names defined in the names option. It doesn't prefix external imports.

If strict is true then add 'use strict'; directive to the IIFE. Default: true.
