Nodejs - Redirect url

How do I get a node.js server to redirect users to a 404.html page when they enter an invalid url?

I did some searching, and it looks like most results are for Express, but I want to write my server in pure node.js.

use

res.redirect('/path/404.html');

or you can redirect to any defined URI as

res.redirect('/');

If you are using ExpressJS, it's possible to use:

res.redirect('your/404/path.html');

Use the following code this works fine in Native Nodejs 

http.createServer(function (req, res) {
var q = url.parse(req.url, true);
if (q.pathname === '/') {
  //Home page code
} else if (q.pathname === '/redirect-to-google') {
  res.writeHead(301, { "Location": "http://google.com/" });
  return res.end();
} else if (q.pathname === '/redirect-to-interal-page') {
  res.writeHead(301, { "Location": "/path/within/site" });
  return res.end();
} else {
    //404 page code
}
res.end();
}).listen(8080);

You have to use the following code:

response.writeHead(302 , {
           'Location' : '/view/index.html' // This is your url which you want
        });
response.end();

I used a switch statement, with the default as a 404:

var fs = require("fs");
var http = require("http");

function send404Response (response){
    response.writeHead(404, {"Content-Type": "text/html"});
    fs.createReadStream("./path/to/404.html").pipe(response);
}

function onRequest (request, response){
    switch (request.url){
        case "/page1":
            //statements
            break;
        case "/page2":
            //statements
            break;
        default:
        //if no 'match' is found
            send404Response(response);
            break;
    }
}

http.createServer(onRequest).listen(8080);

Try this:

this.statusCode = 302;
this.setHeader('Location', '/url/to/redirect');
this.end();

404 with Content/Body

res.writeHead(404, {'Content-Type': 'text/plain'});                    // <- redirect
res.write("Looked everywhere, but couldn't find that page at all!\n"); // <- content!
res.end();                                                             // that's all!

Redirect to Https

res.writeHead(302, {'Location': 'https://example.com' + req.url});
res.end();

Just consider where you use this (e.g. only for http request), so you don't get endless redirects ;-)

To indicate a missing file/resource and serve a 404 page, you need not redirect. In the same request you must generate the response with the status code set to 404 and the content of your 404 HTML page as response body. Here is the sample code to demonstrate this in Node.js.

var http = require('http'),
    fs = require('fs'),
    util = require('util'),
    url = require('url');

var server = http.createServer(function(req, res) {
    if(url.parse(req.url).pathname == '/') {
        res.writeHead(200, {'content-type': 'text/html'});
        var rs = fs.createReadStream('index.html');
        util.pump(rs, res);
    } else {
        res.writeHead(404, {'content-type': 'text/html'});
        var rs = fs.createReadStream('404.html');
        util.pump(rs, res);
    }
});

server.listen(8080);

The logic of determining a "wrong" url is specific to your application. It could be a simple file not found error or something else if you are doing a RESTful app. Once you've figured that out, sending a redirect is as simple as:

response.writeHead(302, {
  'Location': 'your/404/path.html'
  //add other headers here...
});
response.end();
