@nlib/esmify

A command line tool converts tsc output to ESM modules.

What does it do?

Assume you have file1.js and file2.js.

// 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.

// 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');
