# Specify Port Of CRA's Webpack Dev Server
|
|
|
|
[`create-react-app`](https://github.com/facebookincubator/create-react-app)
|
|
gives you a set of scripts, one of which allows you to start a development
|
|
server that bundles and serves your javascript. This is handled under the
|
|
hood via `webpack-dev-server`. By default it attempts to serve from port
|
|
`3000`. If port `3000` is taken it will attempt to connect to another
|
|
sequential port.
|
|
|
|
Alternatively, you can just specify the port when starting the development
|
|
server. This can be done with the `PORT` env var.
|
|
|
|
```bash
|
|
$ PORT=3333 yarn start
|
|
```
