I will create HTTP DELETE Rest API to delete uploaded image from server.

Rest API to Delete Image

I am assuming you have configured my previous tutorial code, if not – not worries , You can also integrate this code with your existing nodejs app. I will demonstrate one by one steps to create delete image API.

Import Node.js file system module

We will import fs module into main nodejs entry file, I am adding below line into app.js file.

,fs = require('fs')

Nodejs API to Delete Image

Let’s create new rest end point to delete image, we will add below code into this file.

const DIR = 'uploads';
app.delete('/api/v1/delete/:imagename',function (req, res) {
  message : "Error! in image upload.";
    if (!req.params.imagename) {
        console.log("No file received");
        message = "Error! in image delete.";
        return res.status(500).json('error in delete');
    
      } else {
        console.log('file received');
        console.log(req.params.imagename);
        try {
            fs.unlinkSync(DIR+'/'+req.params.imagename+'.png');
            console.log('successfully deleted /tmp/hello');
            return res.status(200).send('Successfully! Image has been Deleted');
          } catch (err) {
            // handle the error
            return res.status(400).send(err);
          }
        
      }

});

Here, The imagename variable will have image name which you want to delete.The unlinkSync method of fs module help to delete image from the folder path.The DIR constant will have upload directory path.

If everything fine, You will get success message ‘Successfully! Image has been Deleted’ otherwise get ‘error in delete’ message.
