# cordova-plugin-webserver
2017-07-11 23:35:59 +08:00
*A webserver plugin for cordova*
This plugin helps you to start a full webserver in JavaScript on Android and iOS.
## Why?
I started this project because I wanted a solution like [ExpressJS](http://expressjs.com/de/) but hybrid (for iOS and Android). I didn't want to build two native applications which each serve a backend (two codebases are just bah!). So this is the solution to create a Webserver which can receives HTTP Requests and responds with HTTP Responds.
## Installation
Just add the cordova plugin to your project
`cordova plugin add https://github.com/bykof/cordova-plugin-webserver`
## Use
Ok so it's pretty ez. There are 4 Methods which are available in the `webserver` variable:
- start(port) or start()
- stop()
- onRequest(request)
- sendResponse(responseId, responseObject, callbackSuccess, callbackError)
### start(port)
port (optional): Set a port of your webserver.
Default port: 8080
This method will start your webserver.
### stop()
This method will stop your webserver.
### onRequest(callback(request))
Ok now this is the interesting part...
Everytime a request will be received by the webserver your callback function will be called. In this case you are thinking right! You have to define onRequest BEFORE your start your server. I think it would work also after the start() but I didn't tested it yet.
The params will look like this:
```
{
requestId: '3jh4-ku34k-k3j4k-k3j42',
body: '',
headers: {
... some headers
},
method: 'POST',
path: '/hello/world',
query: 'bla=wer&blu=2'
}
```
### sendResponse(requestId, responseObject, callbackSuccess, callbackError)
If you received a request you will probably send a response "*cough*"...
We need to add a requestId param to map a response to a request, because internally the webserver will wait for the response. (Yes currently the webserver will wait until there aren't computers anymore on earth).
The params have to look like this (there are not default values for the params!):
```
{
status: 200,
body: '<html>Hello ... something</html>',
headers: {
'Content-Type': 'text/html' <--- this is important
}
}
```
## Example
```
webserver.onRequest(
function(request) {
console.log("O MA GAWD! This is the request: ", request);
webserver.sendResponse(
request.responseId,
{
status: 200,
body: '<html>Hello World</html>',
headers: {
'Content-Type': 'text/html'
}
}
);
}
);
webserver.start();
//... after a long long time
// stop the server
webserver.stop();
```
