sqlite3-web

library0.2.1jsnpmunverified

Optimized SQLite and SQLite3 Multiple Ciphers builds for the web (WASM). Version 0.2.1 provides precompiled WebAssembly modules for running SQLite in browser environments. It is released on demand alongside the Dart package. Key differentiators: specifically designed for Flutter web / Dart web apps, supports SQLite3 Multiple Ciphers extension for encryption. Alternative to sql.js with less overhead for Dart projects.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

sqlite3InitModule

✓ import sqlite3InitModule from 'sqlite3-web';

✗ const sqlite3InitModule = require('sqlite3-web');

Package is ESM-only. No CommonJS support.

Sqlite3

✓ import { Sqlite3 } from 'sqlite3-web'; // or: import sqlite3InitModule, { Sqlite3 } from 'sqlite3-web';

Named export for the main class. Often used alongside the default init function.

default (sqlite3InitModule)

✓ import sqlite3InitModule from 'sqlite3-web'; const sqlite3 = await sqlite3InitModule();

✗ import { sqlite3InitModule } from 'sqlite3-web';

sqlite3InitModule is the default export, not a named export. Must be called as a function returning a promise.

Shows initializing the WebAssembly module, creating an in-memory database, executing a query, and closing the db.

import sqlite3InitModule from 'sqlite3-web'; async function main() { const sqlite3 = await sqlite3InitModule(); const db = new sqlite3.oo1.DB(':memory:'); const rows = db.exec('SELECT 1 AS result;'); console.log(rows[0].result); // 1 db.close(); } main().catch(console.error);

Debug

Known issues

gotchasqlite3InitModule must be awaited; it returns a promise.

fix

Use `const sqlite3 = await sqlite3InitModule();`

affects: >=0.0.0

gotchaPackage only works in web browsers (WASM). Not compatible with Node.js or React Native.

fix

Use a different SQLite library for non-web environments, like sql.js for Node.

affects: >=0.0.0

gotchaDefault export is the init function, not the Sqlite3 class. Named export Sqlite3 exists but may be undefined before init.

fix

Always use `import sqlite3InitModule from 'sqlite3-web';` and then call it.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: sqlite3InitModule is not a function

Using a named import instead of default import.

fix

Change to `import sqlite3InitModule from 'sqlite3-web';`

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'DB')

Trying to access sqlite3.oo1 before the module is initialized.

fix

Await the promise returned by sqlite3InitModule().

Error: This package is not supported in this environment

Running outside a web browser (e.g., Node.js).

fix

Use a different SQLite implementation for non-browser environments.
