how to save images with angular nodejs

 There are two ways to save images.

1) store image in database by converting it to binary format.
2) copy image in your project folder then save image path in table.

------- 1st way with front end angular------

pass uploaded file in "handleFileInput" function. 

saveImage(files: FileList) {

  var file:File = files.item(0);

  var myReader:FileReader = new FileReader();

  myReader.onloadend = (e) => {
    this.image = myReader.result;

  }
  myReader.readAsDataURL(file);
  //convert to base64 ends
}

now you will get  binary format image in this.image variable. save this converted image directly to database through API.

------2nd way with api nodejs------

we can use "multer" to copy file in project folder.

const multer = require('multer');

var storage = multer.diskStorage({
  destination: './images',
  filename: (req, file, cb) => {
      cb(null, Date.now() + '-' + file.originalname)
  }
});

const upload = multer({ storage })

//send your image with post request

app.post('/upload', upload.single('image'), (req, res) => {
  
  if (req.file) 
{     
            console.log("Done"); // Success 
            res.send({result:'success'})
}
  else
{
      res.status("409").json("No Files to Upload.");
}
 
});
