Build Status

Home (Web Framework) for Ruff



rap install home


Here's a simple example (code available here):


'use strict';

var Path = require('path');
var Server = require('home').Server;

var server = new Server();

server.use('/', Server.static('static'));

server.get('/', function (req) {
    return {



<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <title>Device Information</title>
    <link rel="stylesheet" href="style.css">
    <h1>Device Information</h1>
        <li>SN: {sn}</li>
        <li>Time: {time}</li>


body {
    font-family: sans-serif;
    color: #666;

h1 {
    font-weight: normal;
    color: #333;

API References

Home provides a simple middleware mechanism based on promise:

// Matches all request with path `/*`.
server.use('/', function (req) {
    // ...

    // If `req` (or a promise with it as value) is returned,
    // otherwise the request stops here.
    return req;

Hosting Static Files

Just like Express, Home provides a built-in (but tiny) static middleware for hosting static files:

server.use('/', Server.static('static'));

The first '/' means that we will try to find a static file for request that matches /*, and 'static' means we are going to find that file under static folder (it could also be an absolute path).

Handling Requests

By returning an object or a promise with an object as its value, Home will response with the correspondent JSON.

// Matches GET requests with path `/`.
server.get('/', function (req) {
    return {
        value: 123

But if a view file is found for the request path, Home will render the view instead:

  • For /foo/bar, it will look for ${viewsDir}/foo/bar.html.
  • For /, it will look for ${viewsDir}/index.html.

Home also provides an ExpectedError class with a statusCode property. When an error of this class is thrown, Home will update the response status code according to the error.

Error views should be named after the status code and put into ${viewsDir}/${errorViewsFolder}.


If you want to handle the response yourself, you can either process the res object directly (following req parameter) or create a concrete class of Response and implement method applyTo(res: ServerResponse): void. If you are going to handle res object directly, make sure headers get sent before the function returns.
