Create image file in nodeJs from blob

rated 0 times [ 169] [ 2] / answers: 1 / hits: 31529 / 6 Years ago, mon, august 6, 2018, 12:00:00

I am receiving BLOB data on nodeJs server which is converted from PNG image.

I need to create again png image on nodeJs server to be able to show it on pdf document.

I had tried to use FileSaver on nodeJs but it is not working.
FileSaver works well on reactJs app.

How can I save a new file to the local directory on the server?

There is a lot question pointing on problems with creating an image file
form blob but I was unable to use base64encode, so other questions were
not helpful.

In BLOB data of png image file there is buffer property.

So I used this solution to create image.

var imageBuffer = request.file.buffer;

var imageName = 'public/images/map.png';



fs.createWriteStream(imageName).write(imageBuffer);

This has solved my problem.
