How to use on server-side? #19

Open ChrisRobston opened 6 years ago

ChrisRobston commented 6 years ago

Hello. Is there an option to use this package on Node backend? It is not available on npm, right? If so, why?

This project relies on the 2D Canvas API that is primarily found in browsers. There might be some nodejs module that implements Canvas, but I have never tried that. If you find a compatible server-side Canvas implementation, you might be able to run this code server-side. I would package it for NPM then.

Thanks for response @ondras I will search this topic next few days. Really hope there's the chance to use this beauty to generate previews of images on server-side. It's incredible.

For now Google show me this https://github.com/Automattic/node-canvas Seems legit.

It's possible and I've done this before using node-canvas and jsdom. Essentially I created a small piece of html to mimic the html page the library uses, loaded that with jsdom, then used node-canvas in place of the browsers Canvas. I was even able to stream the results from a AWS Lambda to a browser via websockets which was kind of neat since multiple people could 'watch' the generation occur in real time.

Though I don't have any code to demonstrate this with unfortunately as I did it quite a while ago.

I've automated it with Puppeteer. Might be overkill.
