Better HTTP Handler (BHH) for node.js

Quickstart

const BHH = require("bhh-node");

var server = new BHH();
server.maxRequestBodySize = 500; //Bytes

server.register_handler(
    "/test/{test_arg}",
    async (request, response, argv)=>{
        console.log(`Received argument ${argv.test_arg}`)
        response.writeHead(
            200,
            {
                "Content-Type": "application/json"
            }
        );
        response.end(JSON.stringify({
            result: "success",
            args: argv
        }));
    }
);

server.register_handler(
    "/test",
    async (request, response, argv) => {
        try{
            var data = JSON.parse(request.body);
        } catch(e){
            server.errorHandler(request, response, {error:400, message:e.message}, 400);
            return;
        }
        response.writeHead(
            200,
            {
                "Content-Type": "application/json"
            }
        )
        response.end(JSON.stringify({
            result: "success",
            data: data
        }));
    },
    "POST"
)

console.log("Listening on port 8080");
server.listen(8080);

Reference

new BHH()

Constructor of the BHH class. No argument is needed.

BHH.listen()

The same as http.Server.listen()

BHH.register_handler(path, handler, method?, optional_trail_slash?)

Argument	Type	Description
path	string	URI format. Using the {} bracket means that the section is a variable. {} is suggested to be used between two slashes.
handler	async function (IncomingMessage, ServerResponse, Object)	The handler. Object in 3rd is the named variables sources from the URI.
method	string	Request method. Default: GET
optional_trail_slash	boolean	If the URI have optional / at the end. Default: true

Property defaultPages

Type	Array(string)
Default value	["index.html", "index.htm"]

A list of filenames that can be served as static file when requesting a directory.

Property errorHandler

Type	function (IncomingMessage, ServerResponse, Object, int)
Default value	BHH.prototype._error

Normalized error handling function.

Third argument is some basic information about the error.

Forth argument is the suggested HTTP status code to be sent.

When server built-in error is triggered (e.g. static file not found), this handler will be triggered like server.errorHandler(request, response, {error: 404, message:"Not found"}, 404)

Property maxRequestBodySize

Type	number
Default value	1000

The maximum allowed size for request body.

Property staticRoot

Type	string
Default value	""

Static file will be searched when no handler available for a path. staticRoot is a path that contains all static files.
