## What it is
wa-sqlite is a WebAssembly build of SQLite with JavaScript-extensible virtual filesystem (VFS) support. It enables running SQLite in the browser with storage backends like IndexedDB and Origin Private File System, in synchronous or asynchronous builds.

## Use cases
- run sqlite in the browser
- persist app data client-side with indexeddb
- store structured data in opfs
- use a real sql database in a web app without a server
- write custom sqlite vfs in javascript
- offline-first web app with local database

## When to choose
- you need full SQL in a browser-based application
- you want client-side persistent storage with IndexedDB or OPFS backends
- you need to customize SQLite behavior via JavaScript VFS extensions

## When to avoid
- you need a server-side or native (non-browser) database
- you only need simple key-value storage without SQL
- your target browsers lack WebAssembly or OPFS support

## Facets
- artifact type: library
- maturity: active
- function: database, database-driver, file-system
- domain: databases, web-development, browser-extensions, developer-tools
- platform: browser, wasm, cross-platform
- tags: sqlite, webassembly, indexeddb, opfs, vfs, browser-storage, sql, javascript
