✅ Decision Checklist
Before designing an API:
- [ ] Asked user about API consumers?
- [ ] Chosen API style for THIS context? (REST/GraphQL/tRPC)
- [ ] Defined consistent response format?
- [ ] Planned versioning strategy?
- [ ] Considered authentication needs?
- [ ] Planned rate limiting?
- [ ] Documentation approach defined?
❌ Anti-Patterns
DON'T:
- Default to REST for everything
- Use verbs in REST endpoints (/getUsers)
- Return inconsistent response formats
- Expose internal errors to clients
- Skip rate limiting
DO:
- Choose API style based on context
- Ask about client requirements
- Document thoroughly
- Use appropriate status codes

datamonsterr/image-processing
development
VerifiedTrustedCommunity
Process images for web development — resize, crop, trim whitespace, convert formats (PNG/WebP/JPG), optimise file size, generate thumbnails, create OG card images. Uses Pillow (Python) — no ImageMagick needed. Trigger with 'resize image', 'convert to webp', 'trim logo', 'optimise images', 'make thumbnail', 'create OG image', 'crop whitespace', 'process image', or 'image too large'.
