I'm looking for the best way to send image files to my server using Apollo Express, and Node. Getting the information there doesn't seem to be an issue, I convert the object into a string but can't find out how to convert it back to a regular file object to store away.
What I have so far;
JS - let buffer = await toBase64(file);
Through Apollo server..
Node - let buffer = Buffer.from(args.image, 'base64');
This gives me a Buffer. I'm unsure how to proceed with NodeJS to convert this back to a file object.
Thanks
I hope this will be helpfull for you
const file = new File([
new Blob(["decoded_base64_String"])
], "output_file_name");
You can use one of the various write or writeFile methods which accept a Buffer.
const fs = require("fs");
let buffer = Buffer.from(
"iVBORw0KGgoAAAANSUhEUgAAAAgAAAAGCAIAAABxZ0isAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsMAAA7DAcdvqGQAAAAQSURBVBhXY/iPAwygxP//AAjcj3EdtT3BAAAAAElFTkSuQmCC",
"base64"
);
fs.writeFile("pic.png", buffer, (err) => {
if (err) throw err;
console.log("The file has been saved!");
});
