sqflite_common_ffi_web 0.2.0+1

Sqflite web implementation using sqlite3 ffi and sqlite3 wasm.

sqflite_common_ffi_web

sqlite Web implementation (experimental). Features:

• Persistency (in indexeddb)
• Cross-tab safe (runs in web worker)

Thanks Simon Binder for the excellent sqlite3 lib.

Setup

Add the dependency:

  dependencies:
    sqflite_common_ffi_web: '>=0.1.0-dev.1'

Setup binaries

Implementation requires sqlite3.wasm binaries into your web folder as well as a sqflite specific shared worker.

You can install binaries using the command:

$ dart run sqflite_common_ffi_web:setup

It should create the following files in your web folder:

• sqflite3.wasm
• sqflite_sw.js

that you can put in source control or not (personally I don't)

Use the proper factory.

// Use the ffi web factory in web apps (flutter or dart)
var factory = databaseFactoryFfiWeb;
var db = await factory.openDatabase(inMemoryDatabasePath);
var sqliteVersion = (await db.rawQuery('select sqlite_version()')).first.values.first;
print(sqliteVersion); // should print 3.39.3

Status

This is still experimental:

• slow
• not fully tested
• bugs
