PubNub Functions 2.0

Core Workflow

1. Identify Function Type: Before Publish, After Publish, On Request, or On Interval
2. Design Logic: Plan the transformation, integration, or business logic
3. Implement Function: Write async/await code with proper error handling
4. Use Modules: Leverage kvstore, xhr, vault, pubnub, crypto modules
5. Validate Implementation: Verify no hardcoded secrets (use vault), confirm async/await usage (no .then() chains), check operation count stays within the 3-operation limit, and ensure proper try/catch wrapping
6. Handle Response: Return ok()/abort() or send() appropriately
7. Configure Channel Patterns: Set wildcard patterns ending with .*, max two literal segments before wildcard
8. Test in Staging: Test the function in PubNub Admin Portal with sample messages before enabling on production channels
9. Deploy to Production: Enable the function on live channel patterns and monitor logs
