SQLite Advanced
SQLite is a lightweight, file-based SQL database used in mobile apps, embedded systems, and edge computing. Advanced skills include query optimization, replication (rqlite, Litestream), full-text search, JSON querying, and production deployments (Cloudflare D1, Vercel Postgres). Learnable in 4–6 weeks with SQL fundamentals. Increasingly critical for serverless, edge, and offline-first architectures. Sits alongside PostgreSQL, cloud databases, and Wasm.
What is SQLite Advanced
SQLite is a lightweight, file-based relational database used in mobile apps, embedded systems, edge computing, and serverless environments. Unlike PostgreSQL or MySQL, SQLite requires no server process, you call it as a library from your application. Advanced SQLite usage involves optimizing queries (indices, EXPLAIN QUERY PLAN), enabling extensions (full-text search FTS5, JSON support), tuning performance with pragmas (WAL mode, cache size), implementing replication (Litestream, rqlite), and deploying to edge networks (Cloudflare D1, Vercel Postgres serverless). SQLite is the most widely deployed database engine in the world, every iOS device, every Android phone, and most web browsers contain SQLite.
