Transform external imports into global variables like Rollup's `output.globals` option. See [rollup/rollup#2374](https://github.com/rollup/rollup/issues/2374)
Installation
------------
```
npm install -D rollup-plugin-external-globals
```
Usage
-----
```js
import externalGlobals from "rollup-plugin-external-globals";
export default {
input: ["entry.js"],
output: {
dir: "dist",
format: "es"
},
plugins: [
externalGlobals({
jquery: "$"
})
]
};
```
The above config transforms
```js
import jq from "jquery";
console.log(jq(".test"));
```
into
```js
console.log($(".test"));
```
It also transforms dynamic import:
```js
import("jquery")
.then($ => {
$ = $.default || $;
console.log($(".test"));
});
// transformed
Promise.resolve($)
.then($ => {
$ = $.default || $;
console.log($(".test"));
});
```
> **Note:** when using dynamic import, you should notice that in ES module, the resolved object is aways a module namespace, but the global variable might be not.
> **Note:** this plugin only works with import/export syntax. If you are using a module loader transformer e.g. `rollup-plugin-commonjs`, you have to put this plugin *after* the transformer plugin.
API
----
This module exports a single function.
### createPlugin
```js
const plugin = createPlugin(
globals: Object | Function,
{
include?: ReadonlyArray | string | RegExp | null,
exclude?: ReadonlyArray | string | RegExp | null,
dynamicWrapper?: Function,
constBindings?: Boolean
} = {}
);
```
`globals` is a `moduleId`/`variableName` map. For example, to map `jquery` module to `$`:
```js
const globals = {
jquery: "$"
}
```
or provide a function that takes the `moduleId` and returns the `variableName`.
```js
const globals = (id) => {
if (id === "jquery") {
return "$";
}
}
```
`include` is a valid `picomatch` glob pattern, or array of patterns. If defined, only matched files would be transformed.
`exclude` is a valid `picomatch` glob pattern, or array of patterns. Matched files would not be transformed.
`dynamicWrapper` is used to specify dynamic imports. Below is the default.
```js
const dynamicWrapper = (id) => {
return `Promise.resolve(${id})`;
}
```
Virtual modules are always transformed.
`constBindings` is a boolean. If true, the plugin will use `const` instead of `var` to declare the variable. This usually happens when you try to re-export the global variable. Default is false.
