How to Implement
1Use UUIDs in Databases
- 1.Generate a UUID v4 (random) for database primary keys.
- 2.In PostgreSQL: Use the uuid type and gen_random_uuid() for auto-generation.
- 3.In your schema: id UUID PRIMARY KEY DEFAULT gen_random_uuid()
- 4.In application code: Generate UUIDs client-side before inserting to avoid round-trips.
- 5.In JavaScript: crypto.randomUUID() (native, no library needed).
- 6.In Python: import uuid; str(uuid.uuid4())
- 7.UUIDs prevent ID enumeration attacks and simplify database merging across systems.
2Use UUIDs in API Design
- 1.Use UUIDs as resource identifiers in your REST API URLs: /api/users/550e8400-e29b-41d4-a716-446655440000
- 2.Generate UUIDs server-side when creating resources.
- 3.Return the UUID in the API response for the client to reference.
- 4.Store as native UUID type in PostgreSQL for optimal storage and indexing.
- 5.In MongoDB, you can use UUIDs instead of ObjectIds for cross-system compatibility.
