absurd-sql is a backend for sql.js (SQLite compiled to WebAssembly) that persists the database in IndexedDB by reading and writing it in small blocks instead of whole-file dumps. It lets web apps run a fully persistent SQLite database entirely in the browser, inside a web worker.

Use cases

• persist a sqlite database in the browser
• run sql queries offline in a web app
• store structured app data client-side without a server
• replace localStorage with a real sql database
• build an offline-first web app with sqlite
• query large datasets in the browser with sql

When to choose

• you want full SQL and SQLite semantics entirely client-side
• your app must work offline with persistent structured data
• you want incremental block-level persistence instead of rewriting a whole database file
• you're building a browser app like a budgeting tool that needs a real database

When to avoid

• you need a server-side or shared multi-user database
• your data is small and simple enough for localStorage or IndexedDB directly
• you can't set COOP/COEP headers or run code in a web worker
• you need broad Safari support or nested workers
• you need a library under active development
