We can upload one or many files in a folder using Nodejs and We also can save its name into a Database. File Upload in Nodejs.
I am using Node framework EXPRESS and multer for file upload into a folder. You can install the express framework by using the below command
npm install express
Install multer using the below command
npm install –save multer file upload node
Now make a file in the Node folder with the named service.js
service.js
var express = require("express"); var multer = require('multer'); var app = express(); var storage = multer.diskStorage({ destination: function (req, file, callback) { callback(null, './uploads'); }, filename: function (req, file, callback) { callback(null, file.fieldname + '-' + Date.now()); } }); var upload = multer({ storage : storage}).single('userPhoto'); app.get('/',function(req,res){ res.sendFile(__dirname + "/index.html"); }); app.post('/api/photo',function(req,res){ upload(req,res,function(err) { if(err) { return res.end("Error uploading file."); } res.end("File is uploaded"); }); }); app.listen(3000,function(){ console.log("Working on port 3000"); });
Now I will use an HTML Form for File uploading,
<form id = "uploadForm" enctype = "multipart/form-data" action = "/api/photo" method = "post" > <input type="file" name="userPhoto" /> <input type="submit" value="Upload Image" name="submit"> </form>
Now Run the project using this command node service.js
This project will run on 3000 Port because I set 3000
