# webpack-dev-server
|
||
|
|
|
||
|
|
Use [webpack](https://webpack.js.org) with a development server that provides
|
||
|
|
live reloading. This should be used for **development only**.
|
||
|
|
|
||
|
|
It uses [webpack-dev-middleware][middleware-url] under the hood, which provides
|
||
|
|
fast in-memory access to the webpack assets.

## Getting Started
|
||
|
|
|
||
|
|
First things first, install the module:
|
||
|
|
|
||
|
|
```console
|
||
|
|
npm install webpack-dev-server --save-dev
|
||
|
|
```
|
||
|
|
|
||
|
|
_Note: While you can install and run webpack-dev-server globally, we recommend
|
||
|
|
installing it locally. webpack-dev-server will always use a local installation
|
||
|
|
over a global one._
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
There are two main, recommended methods of using the module:
|
||
|
|
|
||
|
|
### With the CLI
|
||
|
|
|
||
|
|
The easiest way to use it is with the CLI. In the directory where your
|
||
|
|
`webpack.config.js` is, run:
|
||
|
|
|
||
|
|
```console
|
||
|
|
node_modules/.bin/webpack-dev-server
|
||
|
|
```
|
||
|
|
|
||
|
|
_**Note**: Many CLI options are available with `webpack-dev-server`. Explore this [link](https://webpack.js.org/configuration/dev-server/)._
|
||
|
|
|
||
|
|
### With NPM Scripts
|
||
|
|
|
||
|
|
NPM package.json scripts are a convenient and useful means to run locally installed
|
||
|
|
binaries without having to be concerned about their full paths. Simply define a
|
||
|
|
script as such:
|
||
|
|
|
||
|
|
```json
|
||
|
|
"scripts": {
|
||
|
|
"start:dev": "webpack-dev-server"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And run the following in your terminal/console:
|
||
|
|
|
||
|
|
```console
|
||
|
|
npm run start:dev
|
||
|
|
```
|
||
|
|
|
||
|
|
NPM will automagically reference the binary in `node_modules` for you, and
|
||
|
|
execute the file or command.
|
||
|
|
|
||
|
|
### The Result
|
||
|
|
|
||
|
|
Either method will start a server instance and begin listening for connections
|
||
|
|
from `localhost` on port `8080`.
|
||
|
|
|
||
|
|
webpack-dev-server is configured by default to support live-reload of files as
|
||
|
|
you edit your assets while the server is running.
|
||
|
|
|
||
|
|
See [**the documentation**][docs-url] for more use cases and options.
|
||
|
|
|
||
|
|
## Browser Support
|
||
|
|
|
||
|
|
While `webpack-dev-server` transpiles the client (browser) scripts to an ES5
|
||
|
|
state, the project only officially supports the _last two versions of major
|
||
|
|
browsers_. We simply don't have the resources to support every whacky
|
||
|
|
browser out there.
|
||
|
|
|
||
|
|
If you find a bug with an obscure / old browser, we would actively welcome a
|
||
|
|
Pull Request to resolve the bug.
|
||
|
|
|
||
|
|
## Support
|
||
|
|
|
||
|
|
We do our best to keep Issues in the repository focused on bugs, features, and
|
||
|
|
needed modifications to the code for the module. Because of that, we ask users
|
||
|
|
with general support, "how-to", or "why isn't this working" questions to try one
|
||
|
|
of the other support channels that are available.
|
||
|
|
|
||
|
|
Your first-stop-shop for support for webpack-dev-server should by the excellent
|
||
|
|
[documentation][docs-url] for the module. If you see an opportunity for improvement
|
||
|
|
of those docs, please head over to the [webpack.js.org repo][wjo-url] and open a
|
||
|
|
pull request.
|
||
|
|
|
||
|
|
From there, we encourage users to visit the [webpack Gitter chat][chat-url] and
|
||
|
|
talk to the fine folks there. If your quest for answers comes up dry in chat,
|
||
|
|
head over to [StackOverflow][stack-url] and do a quick search or open a new
|
||
|
|
question. Remember; It's always much easier to answer questions that include your
|
||
|
|
`webpack.config.js` and relevant files!
|
||
|
|
|
||
|
|
If you're twitter-savvy you can tweet [#webpack][hash-url] with your question
|
||
|
|
and someone should be able to reach out and lend a hand.
|
||
|
|
|
||
|
|
If you have discovered a :bug:, have a feature suggestion, or would like to see
|
||
|
|
a modification, please feel free to create an issue on Github. _Note: The issue
|
||
|
|
template isn't optional, so please be sure not to remove it, and please fill it
|
||
|
|
out completely._
