node-sqlite3-compatible API for libSQL
npm install @rhildred/sqlite3sqlite3 wrapper for libSQLThis package is a drop-in replacement of the Node package sqlite3 for use with sqld (the libSQL server mode). Instead of opening a local SQLite database, this package connects to sqld using a WebSocket using the Hrana protocol.
You can get many applications that use the sqlite3 package work with sqld just by replacing require('sqlite3') with require('@libsql/sqlite3'), and using a libsql:// URL instead of a filename:
``javascript
const sqlite3 = require('@libsql/sqlite3').verbose();
const db = new sqlite3.Database('libsql://localhost:2023?tls=0');
db.serialize(() => {
db.run('CREATE TABLE lorem (info TEXT)');
const stmt = db.prepare('INSERT INTO lorem VALUES (?)');
for (let i = 0; i < 10; i++) {
stmt.run('Ipsum ' + i);
}
stmt.finalize();
db.each('SELECT rowid AS id, info FROM lorem', (err, row) => {
console.log(row.id + ': ' + row.info);
});
});
db.close();
`
The library accepts the same URL schemas as [@libsql/client][libsql-client-ts]:
- http:// and https:// connect to a libsql server over HTTP,ws://
- and wss:// connect to the server over WebSockets,libsql://
- connects to the server using the default protocol (which is now HTTP). libsql:// URLs use TLS by default, but you can use ?tls=0 to disable TLS (e.g. when you run your own instance of the server locally).
To use a JWT for authentication, you can use the authToken query parameter (for example,ws://localhost?authToken=).
You can also pass a file: URL to new sqlite3.Database() to use the original sqlite3 package. The returned database will be a Database from sqlite3, not the Database from @libsql/sqlite3. You will need to install sqlite3 yourself, this package does not depend on sqlite3.

You can use this package with Knex.js by replacing the sqlite3 package in the SQLite dialect.
#### JavaScript
`javascript
const Knex = require("knex");
const Client_SQLite3 = require("knex/lib/dialects/sqlite3");
class Client_Libsql extends Client_SQLite3 {
_driver() {
return require("@libsql/sqlite3");
}
}
const knex = Knex({
client: Client_Libsql,
connection: {
filename: url,
},
});
`
#### TypeScript
`typescript
import { Knex, knex } from "knex";
const Client_SQLite3 = require("knex/lib/dialects/sqlite3");
class Client_Libsql extends Client_SQLite3 {
_driver() {
return require("@libsql/sqlite3");
}
}
const db = knex({
client: Client_Libsql as any,
connection: {
filename: url,
},
});

Most APIs exposed by sqlite3 should work as expected, but the following features are not implemented:
- Flags passed to new Database() (they are ignored)Database.configure()
- Database.loadExtension()
- Database.interrupt()
