Uploading files to amazon AWS S3 using Node js + limited; This tutorial will show you how to upload file to amazon s3 bucket using node js + express with express, aws-s3, multer packet.

This uploading files to AWS S3 with Node.js tutorial will create file upload to amazon s3 saucepan using node js + limited + REST API.

Upload File to Amazon s3 bucket using Node JS + Express

Follow the below-given steps to upload single or multiple file to amazon s3 saucepan using node js + express + rest api:

Stride ane – Create Node Express js App
Step ii – Install express, aws-s3, Multer dependencies
Step iii – Create Server.js File
- Import Installed Packages
- Configure AWS-S3 Packet with Multer
- Create Uploading Single File to AWS S3 with Node.js Residual API Route
- Create Uploading MultipleFile to AWS S3 with Node.js REST API Route
Footstep 4 – Start Node Express Js App Server
Pace 5 – Uploading Files to AWS S3 Bucket with Node.js REST API

Footstep 1 – Create Node Express js App

Execute the following command on terminal to create node js app:

mkdir my-app cd my-app npm init -y

Step two – Install express, aws-s3, Multer dependencies

Execute the following command on terminal to install express, aws-s3 and multer dependencies:

npm install express multer aws-sdk body-parser --save

Express — Express is a minimal and flexible Node.js web application framework that provides a robust prepare of features for web and mobile applications.

body-parser — Limited trunk-parser isan npm library used to process data sent through an HTTP request torso. It exposes four express middlewares for parsing text, JSON, url-encoded and raw information fix through an HTTP request body.

AWS-SDK — AWS s3 npm is used to upload or delete an image from the s3 bucket with the help of some keys.

Stride iii – Create Server.js File

Create server.js file; then visit your app root directory and create a new file name server.js.

Then follow the below steps:

Import Installed Packages
Configure AWS-S3 Parcel with Multer
Create Uploading Single File to AWS S3 with Node.js REST API Route
Create Uploading Unmarried File to AWS S3 with Node.js REST API Route

Import Installed Packages

Import above installed dependencies package in server.js file:

var aws = require('aws-sdk') var express = require('express') var multer = require('multer') var multerS3 = require('multer-s3')

Configure AWS-S3 Package with Multer

Then configure aws-s3 package with multer as shown below:

var s3 = new aws.S3({    accessKeyId: " ",    secretAccessKey: " ",    Bucket: " " }) var upload = multer({    storage: multerS3({        s3: s3,        saucepan:"",        metadata: function (req, file, cb) {            cb(null, { fieldName: file.fieldname });        },        cardinal: function (req, file, cb) {            cb(null, Date.now().toString())        }    }) })

Create Uploading Single File to AWS S3 with Node.js Balance API Route

The following node js residuum api route will be upload single file to amazon s3 saucepan:

//Uploading single File to aws s3 bucket app.post('/upload', upload.single('photos'), part (req, res, next) {    res.send({        data: req.files,        msg: 'Successfully uploaded ' + req.files + ' files!'    }) })

Create Uploading Multiple File to AWS S3 with Node.js REST API Road

The following node js residual api route will be upload multiple file to amazon s3 bucket:

//Uploading single File to aws s3 bucket app.mail('/upload', upload.unmarried('photos'), part (req, res, next) {    res.send({        data: req.files,        msg: 'Successfully uploaded ' + req.files + ' files!'    }) })

Open your server js file and add the following code into it:

var aws = require('aws-sdk') var limited = require('express') var multer = require('multer') var multerS3 = require('multer-s3') var app = express() var s3 = new aws.S3({    accessKeyId: " ",    secretAccessKey: " ",    Saucepan: " " }) var upload = multer({    storage: multerS3({        s3: s3,        bucket:"",        metadata: function (req, file, cb) {            cb(nada, { fieldName: file.fieldname });        },        key: role (req, file, cb) {            cb(null, Engagement.now().toString())        }    }) })  //Uploading single File to aws s3 bucket app.mail service('/upload', upload.single('photos'), function (req, res, next) {    res.send({        information: req.files,        msg: 'Successfully uploaded ' + req.files + ' files!'    }) })  //Uploading Multiple Files to aws s3 bucket app.post('/upload', upload.array('photos', 3), office (req, res, next) {    res.send({        data: req.files,        msg: 'Successfully uploaded ' + req.files.length + ' files!'    }) })  app.listen(4000, role () {    console.log('express is online'); })

Step 4 – Kickoff Node Express Js App Server

Execute the following control on last to commencement node express js server:

//run the below control  npm start

Pace 5 – Uploading Files to AWS S3 Bucket with Node.js Residuum API

To upload single or multiple files to aws s3 bucket using node js rest API; And so open postman for sending HTTPmultipart/form-data requests: equally shown below picture:

Conclusion

To upload files to AWS S3 using Node js + express + rest API; Through this tutorial, you lot will learn how to upload files to the amazon s3 bucket using node js + rest api+ express with the limited, aws-s3, multer bundle.
