## Synopsis
2017-07-07 20:25:59 +01:00
This package installs the `ws` command-line tool (take a look at the [usage guide](https://github.com/lwsjs/local-web-server/wiki/CLI-usage)).
2017-07-07 20:35:50 +01:00
### Static web site
2017-07-07 20:25:59 +01:00
The most simple use case is to run `ws` without any arguments - this will **host the current directory as a static web site**. Navigating to the server will render a directory listing or your `index.html`, if that file exists.
2017-06-26 18:36:56 +01:00
```sh
$ ws
Serving at http://mbp.local:8000, http://127.0.0.1:8000, http://192.168.0.100:8000
```
2017-07-07 20:35:50 +01:00
### Single Page Application
2017-07-07 20:25:59 +01:00
2017-07-08 11:16:49 +01:00
Serving a Single Page Application (an app with client-side routing, e.g. a React or Angular app) is as trivial as specifying the name of your single page:
2017-07-07 20:25:59 +01:00
```sh
$ ws --spa index.html
Serving at http://mbp.local:8000, http://127.0.0.1:8000, http://192.168.0.100:8000
```
2017-07-08 11:16:49 +01:00
By default, requests for typical SPA paths (e.g. `/user/1`, `/login`) return `404 Not Found` as a file at that location does not exist. By marking `index.html` as the SPA you create this rule:
2017-07-07 20:25:59 +01:00
2017-07-09 09:10:51 +01:00
*If a static file is requested (e.g. `/css/style.css`) then serve it, if not (e.g. `/login`) then serve the specified SPA and handle the route client-side.*

### URL rewriting and proxied requests
2017-07-07 20:25:59 +01:00
Another common use case is to **re-route certain requests to a remote server** if, for example, you'd like to use data from a different environment. The following command would proxy requests with a URL beginning with `http://127.0.0.1:8000/api/` to `https://internal-service.local/api/`:
2017-06-28 20:13:45 +01:00
2017-06-28 20:26:21 +01:00
```sh
2017-07-01 23:08:30 +01:00
$ ws --rewrite '/api/* -> https://internal-service.local/api/$1'
2017-06-28 20:26:21 +01:00
Serving at http://mbp.local:8000, http://127.0.0.1:8000, http://192.168.0.100:8000
```
2017-06-28 20:13:45 +01:00
2018-03-07 14:42:36 +00:00
### HTTPS
Launching a secure server is as simple as setting the `--https` flag. [See the wiki](https://github.com/lwsjs/local-web-server/wiki) for further configuration options and a guide on how to get the "green padlock" in your browser.
```sh
$ ws --https
Serving at https://mbp.local:8000, https://127.0.0.1:8000, https://192.168.0.100:8000
```
### HTTP2
Uses node's built-in HTTP2 support. HTTP2 servers are always secure using local-web-server's built-in SSL certificates (by default) or those supplied by `--cert`, `--key` or `--pfx`. [See the wiki](https://github.com/lwsjs/local-web-server/wiki) for further info about HTTPS options and a guide on how to get the "green padlock" in your browser.
```sh
$ ws --http2
Serving at https://mbp.local:8000, https://127.0.0.1:8000, https://192.168.0.100:8000
```
2017-07-07 20:35:50 +01:00
### Mock responses
2017-07-07 20:25:59 +01:00
2017-07-08 11:50:17 +01:00
Imagine the network is down or you're working offline, proxied requests to `https://internal-service.local/api/users/1` would fail. In this case, Mock Responses can fill the gap. Mocks are defined in a module which can be reused between projects.
Trivial example - respond to a request for `/rivers` with some JSON. Save the following Javascript in a file named `example-mocks.js`.
```js
module.exports = MockBase => class MockRivers extends MockBase {
mocks () {
return {
route: '/rivers',
responses: [
{
2017-07-08 12:04:28 +01:00
response: {
type: 'json',
body: [
{ name: 'Volga', drainsInto: 'Caspian Sea' },
{ name: 'Danube', drainsInto: 'Black Sea' },
{ name: 'Ural', drainsInto: 'Caspian Sea' },
{ name: 'Dnieper', drainsInto: 'Black Sea' }
]
}
2017-07-08 11:50:17 +01:00
}
]
}
}
}
```
Launch `ws` passing in your mocks module.
```sh
$ ws --mocks example-mocks.js
Serving at http://mbp.local:8000, http://127.0.0.1:8000, http://192.168.0.100:8000
```
GET your rivers.
```sh
$ curl http://127.0.0.1:8000/rivers
[
{
"name": "Volga",
"drainsInto": "Caspian Sea"
},
{
"name": "Danube",
"drainsInto": "Black Sea"
},
{
"name": "Ural",
"drainsInto": "Caspian Sea"
},
{
"name": "Dnieper",
"drainsInto": "Black Sea"
}
]
```
