Nodejs - Redirect url

Question

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

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

You have to use the following code   response writeHead 302                 Location      view index html     This is your url which you want             response end

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

404 with Content Body  res writeHead 404    Content-Type    text plain                            lt - redirect res write  Looked everywhere  but couldn t find that page at all  n        lt - 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  -

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

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
