Inspired by [koa-webpack](https://github.com/shellscape/koa-webpack) plugin.
Under the hood it sets up [webpack-dev-middleware](https://github.com/webpack/webpack-dev-middleware) and [webpack-hot-middleware](https://github.com/webpack-contrib/webpack-hot-middleware).
## Install
```
$ npm i --save-dev fastify-webpack-hmr
```
## Versions
The plugin supports the following `Fastify` and `Webpack` versions. Please refer to corresponding branch in PR and issues.

## Usage
For a more detailed exampe please check out the `example` directory.
The plugin accepts a configuration object, with a following properties:
### compiler
`{object}` `optional`
If you pass a custom `webpack compiler` instance to the plugin, it will pass that to the middlewares.
*Note:* if you pass a `compiler` option the plugin omits the `config` option.
```js
const fastify = require('fastify')()
const HMR = require('fastify-webpack-hmr')
const webpack = require('webpack')
const webpackConfig = require('path/to/your/webpack/config')
const compiler = webpack(webpackConfig)
fastify.register(HMR, { compiler })
fastify.listen(3000)
```
### config
`{string|object}` `optional`
If you pass this option instead of a `compiler`, the plugin tries to set up the webpack compiler and will pass that compiler instance to the middlewares. For the detailed configuration options please check the [`webpack documentation`](https://webpack.js.org/configuration/).
If config is a `string` it has to be a path to a valid webpack configuration file.
```js
const fastify = require('fastify')()
const HMR = require('fastify-webpack-hmr')
const { join } = require('path')
const config = join(__dirname, 'path.to.your.webpack.config')
fastify.register(HMR, { config })
fastify.listen(3000)
```
Or you can directly pass a valid webpack configuration `object`.
```js
const fastify = require('fastify')()
const HMR = require('fastify-webpack-hmr')
const { join } = require('path')
const hotConf = 'webpack-hot-middleware/client?path=/__webpack_hmr'
const config = {
mode: 'development', // Prevents webpack warning
// Add the webpack-hot-middleware to the entry point array.
entry: [join(__dirname, 'path.to.your.client.file'), hotConf],
output: {
publicPath: '/assets',
filename: 'main.js'
}
}
fastify.register(HMR, { config })
fastify.listen(3000)
```
### webpackDev
`{object}` `optional`
Additional configuration options which will be passed to [`webpack-dev-middleware`](https://github.com/webpack/webpack-dev-middleware#options).
### webpackHot
`{boolean|object}` `optional`
You can `disable` webpack-hot-middleware if you set this option `false`.
If it is an `object` it will be passed to [`webpack-hot-middleware`](https://github.com/webpack-contrib/webpack-hot-middleware#config).
## Multi compiler mode
In multi compiler mode you must pass the `webpackDev.publicPath` option to the plugin.
> *Tip:* Don't forget to set name parameter when you register `webpack-hot-middleware` in entry array. It makes sure that bundles don't process each other's updates.
```js
const fastify = require('fastify')()
const HMR = require('fastify-webpack-hmr')
const { join } = require('path')
const hotConf = 'webpack-hot-middleware/client?path=/__webpack_hmr'
const config = [
{
name: 'mobile',
mode: 'development',
entry: [
join(__dirname, 'example', 'mobile.js'),
`${hotConf}&name=mobile`
],
stats: false,
output: { filename: 'mobile.js', publicPath: '/assets' }
},
{
name: 'desktop',
mode: 'development',
entry: [
join(__dirname, 'example', 'desktop.js'),
`${hotConf}&name=desktop`
],
stats: false,
output: { filename: 'desktop.js', publicPath: '/assets' }
}
]
const webpackDev = { publicPath: '/assets' }
fastify.register(HMR, { config, webpackDev })
fastify.listen(3000)
```
## Reference
This plugin decorates the `fastify` instance with `webpack` object. The object has the following properties:
- `compiler` The [`webpack compiler` instance](https://webpack.js.org/api/node/).
- `dev` The [`webpack-dev-middleware` instance](https://github.com/webpack/webpack-dev-middleware#api).
- `hot` The [`webpack-hot-middleware` instance](https://github.com/webpack-contrib/webpack-hot-middleware).
