# @nlib/esmify

[![Test](https://github.com/nlibjs/esmify/actions/workflows/test.yml/badge.svg)](https://github.com/nlibjs/esmify/actions/workflows/test.yml)

A command line tool converts tsc output to ESM modules.

## What does it do?

Assume you have file1.js and file2.js.

```javascript

// file1.js

import {v2} from './file2';

const f2 = import('./file2');

// file2.js

import {external} from '../extenal/file';

import {v1} from './file1';

const f1 = import('./file1');

```

esmify disambiguates import sources in the code.

```javascript

// file1.js

import {v2} from './file2.js';

const f2 = import('./file2.js');

// file2.js

import {external} from '../extenal/file.js';

import {v1} from './file1.js';

const f1 = import('./file1.js');

```
