You can see the Postman request as below. Next, open the Postman application then change the method to `POST` and the URL to ` Change the body to `form-data` then fill the key as file and pick an image file. To test this Express.js application, just run this command. Run and Test the Node.js, Express.js and Multer Image Uploader That REST API sends a response of Image file URL that accessible to Express.js web server. router.post('/upload',upload.single('file'),function(req, res, next) ) Next, create a new route for image upload. If there's no images folder exists, create one inside the public folder. var multer = require('multer') Ĭb(null, 'image-' + Date.now() + '.' + filetype) Īs you can see, we are saving the image file in `public/images` folder and give a name to the image file as `image-date`. Next, open and edit `routes/index.js` then add this required variables that implementing Multer for uploading the image to Express.js server storage . Open and edit `app.js` then change this line.
We will use an existing route for image upload endpoint. Implementing Image Upload in REST API Route Now, you are ready to create REST API service for image upload.
#NODEJS REST API INSTALL#
Next, install modules for uploading an image. We don't need it because we will create a REST API server. There's no view yet using the latest Express generator. Next, go to the newly created project folder then install node modules. Next, create an Express.js app using this command. First, install express-generator using this command. Open your terminal or node command line the go to your projects folder. We will start this tutorial by creating or generating web or REST API application using Express.js. STEP-1: Create a separate folder and with the help of a terminal or command prompt navigate to this folder: STEP-2: Create package.json by typing the following command in the terminal: npm init -y. Let's continue with the main steps.Ĭreate New Express.js Application and Required Modules It will show the installed version of NodeJs to our system as shown in the below screenshot. Next, check their version by type this commands in your terminal or command line. We assume that you have to install Node.js on your machine and can run `node`, `npm` or `yarn` command in your terminal or command line. The following tools, frameworks, and modules are required for this tutorial:
#NODEJS REST API HOW TO#
Now, we will show you how to use it from scratch. To make it simple we are using Multer Node.js library/module. We are using the form `multipart/form-data` `enctype` for upload image using REST API service. A short step by step tutorial on REST API for Image Uploader using Node.js, Express.js, and Multer.
