Let’s start

3. install express, body-parser, multer, mongoose

$ npm i express body-parser multer mongoose

4. Create new file name app.js and Import all things

5. Create Schema and model

6. Now create api for example “Hello world”

7. Now, let’s add storage option, where image will save. In here, ‘./uploads/’ means image will store in uploads folder and filename will be userPost + original filename.

8. add api for image upload. Here upload.single(‘image’) means we can upload only one file at a time. instead of single we can also use upload.any()

9. now sum all of this and your app is ready.
