Worker

This is the worker service that runs background jobs for the app.

Stack

• nodejs >= 20.5
• graphile-worker - background jobs runner for postgres

• nodemailer - email sending
• exifr - exif data parsing
• @react-email - email templating with react

Architecture

Each task is implemented as a separate worker.

All the tasks are located in src/tasks directory.

• convert-image - converts image to multiple sizes and formats, extracts exif data, uploads to s3, triggered by postgres trigger
• delete-image - deletes image from s3, triggered by postgres trigger
• notify-user - sends email notification to user, triggered by postgres trigger

TODO:

• add tests
• split convert-image task into subtasks
