The Origin Private File System (OPFS, part of the File System Access API) is augmented with a special surface that brings very performant access to data. Install the package from npm with the following command: npm install # The Origin Private File System # Using SQLite Wasm with the Origin Private File System persistence backend # Installing the library from npm Support for persistent client-side storage using available JavaScript APIs, including the Origin Private File System (OPFS).A Promise-based variant of the Worker API which entirely hides the cross-thread communication aspects from the user.This one is intended for use in the main thread, with the lower-level APIs installed in a Worker thread, and talking to them via Worker messages. A Worker-based API which speaks to the previous APIs via Worker messages.This API must be used from the same thread as the low-level API. A higher-level object-oriented API, more akin to sql.js and Node.js-style implementations, that speaks directly to the low-level API.Binding a low-level sqlite3 API which is as close to the C one as feasible in terms of usage.The concrete goals of this project include: The sqlite3 WASM/JS subproject is the first effort that is officially associated with the SQLite project making Wasm builds of the library established members of the family of supported SQLite deliverables. There are a number of unofficial SQLite versions based on Web Assembly (Wasm), allowing it to be used in web browsers, for example, sql.js. Instead, the database is stored in a single file on the user's device, making it easy to integrate into applications. One of the key features of SQLite is that it is a serverless database, which means that it does not require a separate server process to operate. Because of its small size and low memory requirements, SQLite is often leveraged as a database engine in mobile devices, desktop applications, and web browsers. Many developers use it to store data in a structured, easy-to-use manner. SQLite is a popular, open-source, lightweight, embedded relational database management system. The SQLite Wasm library with the Origin Private File System persistence backend is our fulfillment of this promise. Deleting data from a Python program: guides you on how to delete one or more rows in a table from a table using Python sqlite3 module API.In our blog post Deprecating and removing Web SQL, we promised a replacement for Web SQL based on SQLite.Selecting data: this tutorial shows you how to query data in an SQLite database from a Python program.Updating data in the SQLite database using Python: learns how to update existing data in the SQLite database using Python. ![]() Inserting data into the SQLite database in Python: walks you through the steps of inserting data into a table in SQLite database using Python.Create tables in SQLite database using Python: shows you step by step how to create tables in an SQLite database from a Python program.Creating an SQLite database from a Python program: shows you how to create a new SQLite database from a Python program using the sqlite3 module.We will use the PySQLite wrapper to demonstrate how to work with the SQLite database library using Python. It even allows you to write a virtual table implementation using Python. The APSW is designed to mimic the native SQLite C, therefore, whatever you can do in SQLite C API, you can do it also from Python.īesides covering the SQLite library, the APSW provides many low-level features including the ability to create user-defined aggregate, function, and collations from Python. The APSW provides the thinnest layer over the SQLite database library. If your application needs to support only the SQLite database, you should use the APSW module, which is known as Another Python SQLite Wrapper. PySQLite is a part of the Python standard library since Python version 2.5 APSW The PySQLite provides a standardized Python DBI API 2.0 compliant interface to the SQLite database. If your application needs to support not only the SQLite database but also other databases such as MySQL, PostgreSQL, and Oracle, the PySQLite is a good choice. Each interface targets a set of different needs. Python provides two popular interfaces for working with the SQLite database library: PySQLite and APSW. This section shows you step by step how to work with the SQLite database using Python programming language. ![]()
