Quick Start
SQLite is an embedded database. It doesn't run as a background service; it is just a C library that reads and writes directly to an ordinary disk file.
sqlite3 mydatabase.db
Production Patterns
WAL Mode
By default, SQLite uses a rollback journal which blocks all readers during a write. For production web applications, you MUST execute PRAGMA journal_mode=WAL;. This enables Write-Ahead Logging, allowing concurrent readers and writers.
Architecture & Scaling
Edge Replication
Modern cloud-native platforms like Turso (libSQL) or Cloudflare D1 allow you to replicate SQLite files directly to edge nodes worldwide, enabling sub-millisecond local reads with global consistency.
Error Recovery
If you receive SQLITE_BUSY errors, increase the busy timeout (PRAGMA busy_timeout = 5000;). This tells SQLite to wait for 5 seconds for a lock to clear before throwing the exception.
Security Notes
SQLite files should never be placed in a public-facing web directory. Secure the file permissions to ensure only the application process owner can read or write the .db file.

Why use this skill
Use this when your agent works with sqlite — structured patterns beat pasted docs and prevent common hallucinations.
AI pitfalls
- Inventing column names or schema fields
- Using deprecated driver methods or wrong connection strings
- Omitting connection pooling or transaction boundaries
Production checklist
- Migrations version-controlled and applied via CI
- Connection limits and pooling configured
- Backups and restore procedure documented
