Fastify Babel plugin for development servers

### Never load this plugin on production servers

The purpose of this module is for running a test HTTP server directly from

sources.  Babel transformations are not async and all additional requests are

blocked while transformation is in process.

You should always use a build step to install pre-transformed files to production

servers.

### Install fastify-babel

This module requires node.js 10 or above.  It is should normally be used

with `fastify-static >= 0.12.0`.  This module requires the local filename

to be in `payload.filename`.

```sh

npm i --save-dev fastify-babel @babel/core

```

## Usage

```js

'use strict';

const path = require('path');

const fastify = require('fastify')();

const fastifyStatic = require('fastify-static');

const fastifyBabel = require('fastify-babel');

fastify

	.register(fastifyStatic, {

		root: path.join(__dirname, 'html/myapp'),

		prefix: '/myapp',

	})

	.register(fastifyStatic, {

		root: path.join(__dirname, 'node_modules'),

		prefix: '/node_modules',

		decorateReply: false,

	})

	.register(fastifyBabel, {

		babelrc: {

			plugins: ['bare-import-rewrite'],

		},

	})

	.listen(3000, '127.0.0.1', err => {

		if (err) {

			throw err;

		}

		console.log(`server listening at http://127.0.0.1:${fastify.server.address().port}/`);

	});

```

In addition to `fastify-babel` this example requires `fastify-static` and

`babel-plugin-bare-import-rewrite`.

## Options

### `babelrc`

An object provided directly to babel for each request that is processed.

Default is empty.

### `babelTypes`

A `RegExp` object used to match the `Content-Type` header.  Only replies with

matching header will be processed by babel.  Default `/(java|ecma)script/`.

### `maskError`

Setting this to `false` will allow the full error message to be displayed.  By

default errors are masked to prevent disclosure of server details.

### `cache`

A Map-like object for caching transform results.  This object must have support

for both `get` and `set` methods.

### `cacheHashSalt`

A string used to salt the hash of source content.
