ReadFile in Base64 Nodejs

Question

I'm trying to read an image from client side encoded in base64. How to read with nodejs?

My code:

// add to buffer base64 image var encondedImage = new Buffer(image.name, 'base64');  fs.readFile(encondedImage, "base64", function(err, buffer){     if ( err ) {         console.log('In read file')         console.log(err)     } else {         // check err         lwip.open(buffer, 'jpg', function(err, image){             console.log('in open')             if ( err ) console.log(err)              if ( image ) console.log(image)             // check 'err'. use 'image'.             // image.resize(...), etc.         });     } }) 

But, I got this error:

In read file [Error: Path must be a string without null bytes.]

Latest and greatest way to do this:

Node supports file and buffer operations with the base64 encoding:

const fs = require('fs'); const contents = fs.readFileSync('/path/to/file.jpg', {encoding: 'base64'}); 

Or using the new promises API:

const fs = require('fs').promises; const contents = await fs.readFile('/path/to/file.jpg', {encoding: 'base64'});
