Migrating background jobs to Elixir is easy with Oban because everything lives in your PostgreSQL database. Oban relies on a structured oban_jobs table as its job queue, and purposefully uses portable data structures (JSON) for serialization. That makes it enqueueing jobs into Oban simple for any language with a PostgreSQL adapter, no Oban client necessary.

As a demonstration, let's explore inserting Oban jobs from a Rails application.

To start, define a skeletal ActiveRecord model with a few conveniences for scheduling jobs:

Upload a file with $.ajax to AWS S3 with a pre-signed url

When you read about how to create and consume a pre-signed url on this guide, everything is really easy. You get your Postman and it works like a charm in the first run.

Then you open your browser, try your usual $.ajax() and send your PUT operation, and you hit the cold iced wall of AWS error message, a simple <Code>SignatureDoesNotMatch</Code> that will steal hours from your productivity.

So here I come to save you and give you a free working example of how to upload a file directly to AWS S3 from your browser. You are wellcome :).
