Bun's raw HTTP throughput beats Node.js by 4x — until a real Postgres query collapses that gap to 3%. The 2026 data on speed, cold starts, and migration risk.
Just use Postgres for everything: in July 2026 one instance absorbs caching, queues, full-text search and vectors, erasing the tax of seven systems.
Drizzle vs Prisma in 2026: Drizzle ships a ~7.4 KB bundle while Prisma 7 swaps its Rust engine for WASM. Bundle size, edge cold starts and a decision table.
A downstream dependency slowed down for 90 seconds — our retry logic took it down completely. Here's what jittered backoff actually prevents, and why.
A list endpoint was firing 400 queries and taking 6 seconds to load. Here's how we detected the N+1 problem and cut it down to 2 queries with eager loading.
A payment request timed out, the mobile app retried automatically, and the customer got charged twice. Here's how idempotency keys and UPSERT prevent that.
Database indexing explained with real PostgreSQL 18 examples: how B-trees work, EXPLAIN ANALYZE proof, index types compared, and how skip scan changes the leftmost-prefix rule.
Most developers still treat REST vs GraphQL as a two-horse race. As of July 2026 that framing is stale. Here is the honest comparison, with tRPC and gRPC in the picture.
