A _micro_ helper for `import.meta` data.

# Announcement

This module is currently redundant thanks to `import.meta.dirname` and `import.meta.filename` landed in NodeJS LTS.

In Bun those would be the equivalent of `import.meta.dir` and `import.meta.dir + '/' + import.meta.file`.

I think it'd be rather better to normalize Bun than keep parsing `import.meta.url` but basically all I am saying is that this module is dead for good.

### normalization for both NodeJS and Bun

```js

const {

  dirname = import.meta.dir,

  filename = `${import.meta.dir}/${import.meta.file}`,

} = import.meta;

console.log(dirname);

console.log(filename);

```

- - -

```js

import umeta from 'umeta';

const {dirName, fileName, require} = umeta(import.meta);

```

The `dirName` and `fileName` respectively represent `__dirname` and `__filename`, while the `require` utility helps importing conditionally, or on demand, CommonJS friendly modules.

### How to transform `import.meta` for CommonJS ?

There are at least two options:

  * [ascjs](https://github.com/WebReflection/ascjs/#readme), based on `@babel/parser`

  * [ucjs](https://github.com/WebReflection/ucjs/#readme), based on `@babel/core` and with minimal dependencies (compatible with dynamic `import(...)` too)
