# rollup-plugin-force-binding

Force all import bindings for a module to come from one absolute source.

Useful for bundles with [multiple entry points](https://github.com/rollup/rollup-plugin-multi-entry) that have shared dependencies at different absolute paths.

```js

// entry A

import SomeClass from 'some-dependency/src/SomeClass';

// resolved path: ~\path\to\A\node_modules\some-dependency\src\SomeClass

// entry B

import SomeClass from 'some-dependency/src/SomeClass';

// resolved path: ~\path\to\B\node_modules\some-dependency\src\SomeClass

// resulting in bundled duplicates

var SomeClass = (function () {})();

var EntryA = (function (_SomeClass) {})(SomeClass);

var SomeClass$2 = (function () {})();

var EntryB = (function (_SomeClass) {})(SomeClass$2);

```

## Install

```

$ npm i rollup-plugin-force-binding [--save-dev]

```

## Usage

If used in junction with [node-resolve](https://github.com/rollup/rollup-plugin-node-resolve), place force-binding BEFORE in the plugin array.

```js

import forceBinding from 'rollup-plugin-force-binding';

rollup.rollup({

  plugins: [

    forceBinding([

      // regular module

      'some-dependency',

      // pathed module (some-dependency/src/Asset.js)

      'Asset' // 'Asset.js' also valid

    ])

  ]

});

```

## Caveat

Rollup's plugin model does not expose the import names, only the paths.

```js

import { SomeClass, AnotherClass } from 'some-dependency';

```

As such, the above code cannot be deduped. This is why you must path to the source file. I have submitted a [feature request](https://github.com/rollup/rollup/issues/1301) to expose import names.
