I want to upload an image to the blob field in mysql using nodejs and use angular to display that blob as an image any ideas how to do it?

What I have tried:

Nodejs:-
const image = fs.readFileSync(file.path);
let base64data = image.toString('base64');
db.query(qr, (err, result) => {
if(err){
res.send({
err
})
}else{
res.send({
message: "data sent successfully"
})
}
})
Angular:-

ts file: -
 display(){
    const reader = new FileReader();
    this.http.get('http://localhost:5000/image').subscribe((res:any)=>{
      console.log(res);
      this.readData = res.response[0];
  })
