Consider the following project structure

    |-- .. 
    '-- src
       |-- ..
       |-- index.js
       '-- utils
           |-- ..
           |-- util1.js
           |-- util2.jsm
           '-- index.js


and plugin options

```json
{
  "extensions": [".js", ".jsm"],
  "alias": {
    "somelib": "./node_modules/other_lib/src/"
  }
}
```

### Resolve "index" file if import points to a directory

```js
// src/index.js

import * as utils from "./utils"; 
// resolved to ./utils/index.js
```

### Resolve extensions

```js
// src/utils/index.js

import util1 from "./util1"; 
// resolved to ./util1.js
import util2 from "./util2"; 
// resolved to ./util2.jsm

export {util1 as u1, util2 as u2};
```

### Resolve aliases

```js
// src/utils/util1.js

import somelib from "somelib";
// resolved to ./node_modules/other_lib/src/index.js

import component1 from "somelib/component1";
// resolved to ./node_modules/other_lib/src/component1.js
// OR if component1 is a folder ./node_modules/other_lib/src/component1/index.js
```
