SQLite3 with vanilla JavaScript and OPFS – Hello world

In this post I will show you how to use SQLite3 directly in the web browser using the original C library through WebAssembly and OPFS to store the database. In this way we will have original SQLite3 on the web to work in the browser with JS on the client side.

We can do this with pure JavaScript or with any framework; but I will show you a basic and well explained example of SQLite3 with vanilla JavaScript. Then I’ll show you an example with Tailwind, Svelte and Progressive Web apps.
