##p4a
It is a simple nodejs server integrated with body, cookie parsing, file upload handler, cors connection etc.
####Create simple server:
import { Server } from "p4a";
let server = new Server();
server.listen({port:8080});
Serve static files
Serves static files from the given path
server.serveStatic(__dirname+'/public');
Create Api over http
Make get
and post
requests
let endpoint = server.Api().endpoint();
endpoint.get('/', (req: Request, res: Response)=>{
res.success({message: "Simple end point"}); // will send {status: true, data: {message: "Simple end point"}}
})
Access Express Request
and Response
you can access express req
and res
too using req.req
and res.res
in callback
let endpoint = server.Api().endpoint();
endpoint.get('/', (req: Request, res: Response)=>{
let expressRequest = req.req;
res.res.json({message: "Simple end point"}); // will send {status: true, data: {message: "Simple end point"}}
})
Access requested body, cookies, form with files from the request
You can access requested body, cookies, form with files from the request without mounting any middleware
let endpoint = server.Api().endpoint();
endpoint.post('/',(req: Request, res: Response)=>{
let body = req.body(); // Requested body
let cookie = req.cookies(); // Requested cookies
// Requested form with files
req.form((err, fields, files) => {
console.log("err: ", err);
console.log("fields: ", fields);
console.log("form: ", files);
});
console.log("body: ", body);
console.log("cookies: ", cookie);
res.cookie("hello", "Hello world"); // Set cookies
res.success(true); // will send {status:1, data: true}
//res.error(123, true); // will send {status:0, type: 123, message: true}
});
Endpoint chaining
let endpoint = server.Api().endpoint();
let college = new Endpoint();
let department = new Endpoint();
let library = new Endpoint();
college.hookup("library", library);
college.hookup("department", department);
endpoint.hookup("college", college)
Establish real time connection over socket
let socket = server.Api().socket();
socket.to('/chat', (connection: SocketConnection)=>{
console.log("Connected");
// Emit 'test' to the socket
connection.socket.emit("message", "new message from p4a server over socket");
// Handle when clients emits 'test'
connection.socket.on("message", (d:any)=>{
console.log(d);
});
});
Configure filesystem
Configure where to upload the file for more information see the documentation
server.fileSystem.Config({
uploadDir: 'upload' // File upload directory
});
Allow origins to access server
Allow all origins
server.allowOrigins("*")
Allow single origin
server.allowOrigins("http://localhost:4200")
Allow multiple origins
server.allowOrigins(["http://localhost:4200", "http://localhost:4300", "http://localhost:4400"])
Full example
import {Endpoint, SocketConnection, Response, Request, Server} from "p4a";
let server = new Server();
// Allow origin to access server
server.allowOrigins('http://localhost:4200');
// Configure file system
server.fileSystem.Config({
uploadDir: 'upload'
});
let endpoint = server.Api().endpoint(); // Handle http requests
// Static form
endpoint.serveStatic(__dirname+'/docs', {path:'/static'});
//http://localhost:8088/hi
endpoint.get('/hi', (req: Request, res: Response)=>{
res.success({data: "data"});
});
endpoint.post('/',(req: Request, res: Response)=>{
let body = req.body(); // Requested body
let cookie = req.cookies(); // Requested cookies
// Requested form
req.form((err, fields, files) => {
console.log("err: ", err);
console.log("fields: ", fields);
console.log("form: ", files);
});
console.log("body: ", body);
console.log("cookies: ", cookie);
res.cookie("hello", "Hello world"); // Set cookies
res.success(true); // will send {status:1, data: true}
//res.error(123, true); // will send {status:0, type: 123, message: true}
});
let socket = server.Api().socket(); // Handle sockets
//Connect socket.io on http://localhost:8088/namespace
socket.to('/namespace', (connection: SocketConnection)=>{
console.log("Connected");
// Emit 'test' to the socket
connection.socket.emit("test", "test done");
// Handle when clients emits 'test'
connection.socket.on("test", (d:any)=>{
console.log(d);
connection.socket.emit('test', d.toString()+": received")
});
});
// start server on port 8088
server.start({port:8088});
Simple static files serving with p4a
Serve static files
import {Server} from "p4a";
let server = new Server();
// Static form
server.serveStatic(__dirname+'/docs');
// start server on port 8088
server.start({port:8088});
