A Node.js library to handle custom URL protocols and route them to specific API paths.
To install the package, use npm:
npm install urlprotocol
The library allows you to define custom URL protocols and route them to specific API paths. Below is an example of how to use the package:
Create a file named test.js
and add the following code:
const CustomProtocolHandler = require('urlprotocol');
const protocolHandler = new CustomProtocolHandler('hello');
protocolHandler.register('/alertmessage', (req, res) => {
res.writeHead(200, { 'Content-Type': 'application/json' });
res.end(JSON.stringify({ message: 'This is an alert message!' }));
});
protocolHandler.start(3000);
In this example, when the URL hello://alertmessage
is called, it will respond with a JSON message: {"message":"This is an alert message!"}
.
-
constructor(protocol)
- Creates a new CustomProtocolHandler for the specified protocol.
-
register(path, handler)
- Registers a handler function for the specified path.
-
start(port)
- Starts the HTTP server on the specified port.
Here's a complete example of how to use the library:
const CustomProtocolHandler = require('urlprotocol');
const protocolHandler = new CustomProtocolHandler('hello');
protocolHandler.register('/alertmessage', (req, res) => {
res.writeHead(200, { 'Content-Type': 'application/json' });
res.end(JSON.stringify({ message: 'This is an alert message!' }));
});
protocolHandler.register('/greeting', (req, res) => {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end('Hello, world!');
});
protocolHandler.start(3000);
In this example, two paths are registered: /alertmessage
and /greeting
. The hello://alertmessage
URL will respond with a JSON message, and the hello://greeting
URL will respond with a plain text message.
