How do I upload a base64 encoded image (string) directly to a Google Cloud Storage bucket using Node.js?

Question

Currently, I am using the @google-cloud/storage NPM package to upload a file directly to a Google Cloud Storage bucket. This requires some trickery as I only have the image\

Answer 1

I was able to get the base64 string over to my Cloud Storage bucket with just one line of code.

var decodedImage = new Buffer(poster64, 'base64');
        

// Store Poster to storage
let posterFile = await client.file(decodedImage, `poster_${path}.jpeg`, { path: 'submissions/dev/', isBuffer: true, raw: true });
let posterUpload = await client.upload(posterFile, { metadata: { cacheControl: 'max-age=604800' }, public: true, overwrite: true });
let permalink = posterUpload.permalink

Something to be aware of is that if you are inside of a Nodejs environment you wont be able to use atob().
