nodejs http module - image upload

Question

I am pretty supcied there is not a stack question about this. How can i create a nodejs http module file upload?

I have a server, witch will reaceave a file + some form parameters, how can i get the image( i will need to resize the image, then upload to other server later ).

My current code:

 17 // Searches Elasticsearch and return's firebase references
 18 http.createServer(function(request, response) {
 19   var method = request.method;
 20   var url = request.url;
 21   var body = [];
 22 
 23   // Fetches body and pushes into array
 24   request.on('error', function(err) {
 25     console.error(err);
 26   }).on('data', function(chunk) {
 27     body.push(chunk);
 28   }).on('end', function() {
 29     body = Buffer.concat(body).toString();
 30     response.statusCode = 200;
 31     response.setHeader('Content-Type', 'application/json');
 32 
 33     // Mini router
 34     if(url == "/save_photo") {
 35       upload_photo.resizeAndSavePhoto(request);
 36       response.write("body");
 37       response.end();
 38     } else {
 39       search.searchElasticsearchForMaches(request, url, elasticsearchUrl, elasticsearchPort).then((data) => {
 40         response.write(data);
 41         response.end();
 42       });
 43     }
 44   });
 45 }).listen(8080);



  1 var http = require('http');
  2 
  3 module.exports = {
  4   resizeAndSavePhoto: function(body) {
  5     console.dir(body.files);
  6   }
  7 };

You can use either ImageMagick or GraphicsMagick i would prefer gm as it is more better in performance and stable for node.Graphic magick should be install on your server

you can install gm like this

npm install gm

For more details check this http://aheckmann.github.io/gm/docs.html
