SQLite Client

SQLite Client is a wrapper for SQLite that uses the Origin Private File System (OPFS) to persist the SQLite database file.

This library supports the following backing mechanism:

• In Memory (Main Thread)
• In Memory (Worker)
• OPFS (Worker)
• OPFS SyncAccessHandles (Worker)

Installation using NPM

This library has two important files: sqlite-client.js and sqlite-client-worker.js. Behind the scenes, the SqliteClient communicates with a worker (if needed) to run the SQL statements and return you the results on the main thread. It also supports the Memory Main Thread mode.

1- Install the NPM package

npm install @sozoo-k5u/sqlite-client

1- Import the sqlite-client library in your code and use it as such:

Memory Main Thread

import {SqliteClient} from "@sozoo-k5u/sqlite-client";

const filename = "/test.sqlite3"; // This is the name of your database. It corresponds to the path in the OPFS.

const sqliteClient = new SqliteClient({
    type: SqliteClientTypeEnum.MemoryMainThread,
    filename,
    flags: "c", // See sqlite documentation for which flags to use    
})

Memory Worker

import {SqliteClient} from "@sozoo-k5u/sqlite-client";

const sqliteWorkerPath = "assets/js/sqlite-client-worker.js"; // Must correspond to the path in your final deployed build.
const filename = "/test.sqlite3"; // This is the name of your database. It corresponds to the path in the OPFS.

const sqliteClient = new SqliteClient({
    type: SqliteClientTypeEnum.MemoryWorker,
    filename,
    sqliteWorkerPath,
    flags: "c", // See sqlite documentation for which flags to use
})

OPFS Worker

import {SqliteClient} from "@sozoo-k5u/sqlite-client";

const sqliteWorkerPath = "assets/js/sqlite-client-worker.js"; // Must correspond to the path in your final deployed build.
const filename = "/test.sqlite3"; // This is the name of your database. It corresponds to the path in the OPFS.

const sqliteClient = new SqliteClient({
    type: SqliteClientTypeEnum.OpfsWorker,
    filename,
    sqliteWorkerPath,
    flags: "c", // See sqlite documentation for which flags to use
})

OPFS Sync Access Handle Worker

import {SqliteClient} from "@sozoo-k5u/sqlite-client";

const sqliteWorkerPath = "assets/js/sqlite-client-worker.js"; // Must correspond to the path in your final deployed build.
const filename = "/test.sqlite3"; // This is the name of your database. It corresponds to the path in the OPFS.

const sqliteClient = new SqliteClient({
    type: SqliteClientTypeEnum.OpfsSahWorker,
    filename,
    sqliteWorkerPath,
})

1- With the client instantiated, you need to initiate it and then you can execute SQL Queries

await sqliteClient.init();

await sqliteClient.executeSql("CREATE TABLE IF NOT EXISTS test(a,b)");
await sqliteClient.executeSql("INSERT INTO test VALUES(?, ?)", [6,7]);
const results = await sqliteClient.executeSql("SELECT * FROM test");

1- Copy the node_modules/@magieno/sqlite-client/dist/bundle/sqlite-client-worker.js to your final bundle This is dependent on the framework you are using but the idea is that this .js file should be copied and available in your build.

1- Copy the files node_modules/@sqlite.org/sqlite-wasm/sqlite-wasm/jswasm/* file to your final bundle next to sqlite-client-worker.js.

1- Warning Your server must set the following Http headers when serving your files

Cross-Origin-Opener-Policy: same-origin

Cross-Origin-Embedder-Policy: require-corp
