question.. web push notifications having trouble with modules
Dam that was a long 18 + hours trying to make my code function. Just when I was so close to finishing it there were just so many failures and the web push library from NPM I converted to Deno wouldn’t work without the crypto module.

question.. web push notifications having trouble with modules
Thank you I’m going to try that. I’m still learning Deno and coming from php it’s been a bit of a curve but one that I’m loving and happy to be moving to. I’m working on each area of a production level system so we are 100% Deno and increase performance.
