# Babylonia



A zero-dependency package which vendors _all_ [@babel] modules for security and

simplicity. It follows the same versioning scheme as babel:

e.g. `[email protected]` includes `@babel/[email protected]`.



## Usage



Simply require `babylonia` instead of `@babel/core`. All modules typically

residing under `@babel/` will resolve with `babylonia/` as a prefix.



``` js

const fs = require('fs');

const path = require('path');

const babel = require('babylonia');

const filename = path.resolve(process.argv[2]);



const options = {

  presets: [

    ['babylonia/preset-env', {

      targets: {

        browsers: ['last 2 versions']

      },

      useBuiltIns: 'usage',

      loose: true

    }]

  ],

  filename,

  code: true,

  ast: false

};



const config = babel.loadPartialConfig(options);

const code = fs.readFileSync(filename, 'utf8');



babel.transform(code, config.options, (err, result) => {

  if (err)

    throw err;



  console.log(result.code);

});

```



As an extra bonus, babylonia users never have to consider which @babel modules

to add to their package.json.



## CLI Usage



This module will provide `babel`, `babel-external-helpers`, `babel-node`, and

`babel-parser` commands. This will conflict with the regular `@babel/cli`,

`@babel/node`, and `@babel/parser`.



``` bash

$ babel -h

```



## Disclaimer & Reasoning



Although its snappy name may make it look like one, Babylonia is _not_ an

official @babel module. It's simply a snapshot of all @babel NPM packages. It

was specifically created for the [bcoin] development cycle. Bcoin is a

cryptocurrency project whose devs and users are particularly target-able for

certain kinds of package attacks like the one seen on the `event-stream`

package. As such, we seek to minimize the NPM attack surface.



### Why not use shrinkwrap?



Bundling the dependencies directly allows one to clone directly from github

without having to run `npm install`. We are aiming to minimize reliance on NPM

altogether.



### Why not use babel-standalone?



`babel-standalone` by itself does not provide a complete solution. Several

plugins and presets would still need to be included. Furthermore, as of

[email protected] `babel-preset-env-standalone` is broken and throws an error when

required.



### Why not bundle it?



Babel is a massive codebase and it is non-trivial to compile it into a single

file (as evidenced by the official babel-preset-env-standalone package not even

working!), especially when its baked-in behavior assumes dynamic requires for

things like presets and plugins.
