wordpress-playground VS Pentive

Sorry friend, WordPress already beat you to it: https://github.com/WordPress/wordpress-playground

> Is there a reason why using OPFS directly from SQLite doesn't work?

I'm guessing this means using SQLite WASM's built-in OPFS integration as described in these articles:

- sqlite3 WebAssembly documentation - Persistent Storage Options: OPFS - https://sqlite.org/wasm/doc/trunk/persistence.md#opfs

- SQLite Wasm in the browser backed by the Origin Private File System - https://developer.chrome.com/blog/sqlite-wasm-in-the-browser...

Within the Playground, SQLite interacts with the database file in MEMFS only, and the Playground coordinates the syncing from MEMFS to OPFS.

https://github.com/WordPress/wordpress-playground/tree/trunk...

The reason for this, I believe, is that the primary use case is/was to have the entire file system in memory, including SQLite's database file. This was the original implementation, and is still the default behavior. Persistence was later added as an optional feature.

The good news is that browser support for OPFS seems to be getting better. From the SQLite docs:

  As of March 2023 the following browsers are known to have the necessary APIs:

One of the most exciting things at WordCamp Europe 2023 for me was discovering how far along the WordPress Playground project is. If you haven’t heard of the playground before, it’s a full version of WordPress, running directly in your browser!

WordPress has an official WebAssembly build for the browser and Node.js: https://developer.wordpress.org/playground https://github.com/WordPress/wordpress-playground

(Disclosure: I'm the creator)

I love the work going on there at WasmLabs, especially enjoying the articles with in-depth technical explorations.

After the article about running WordPress in the browser was published, there's a new project called WordPress Playground which is gradually preparing NPM or Composer packages to make it easier for people to run it.

They've been doing very detailed work, like making some patches to PHP and SQLite for improved compatibility with Emscripten, etc. It seems there's a lot of overlap with what WasmLabs has achieved and probably have continued to develop further. Perhaps there's an opportunity for collaboration.

Shameless plug - I'm building https://github.com/AlexErrant/Pentive which is basically GitHub/Reddit for flashcards. Very much pre-product and a WIP, though the offline client proof of concept is done.

I also enjoyed the Treesitter talk from 5 years ago by Max Brunsfeld https://www.youtube.com/watch?v=Jes3bD6P0To

I'm currently building a query language whose grammar is very much inspired by Github's search syntax. I'm using Lezer, which is a GLR like Treesitter, so this talk learned me some parser generators (I've no formal CS education). Here's my grammar, a playground, and an example search query if anyone wants to play with it

Not really. There are options for sharing cards on Anki https://www.reddit.com/r/Anki/comments/14j2jfy/deck_sharing_... but their collaboration features are limited.

I myself am building an Anki clone https://github.com/AlexErrant/Pentive with collaboration built in as a first class citizen, though its far from primetime. Currently stewing on how to get the SR algorithm, FSRS, to compile to wasm.

A free, open source, local-first, spaced repetition system that works offline, has p2p syncing, plugins, and first class support for collaboration. It's GitHub/Reddit for flashcards.

I basically took Anki and turned it into a webapp >_>

I find Solid's model pretty damn close to "compiling down to nothing". I chose Solid for my project because I wanted to support plugins that used other UI frameworks. I recently got a Svelte plugin working with the SolidJS router. I could probably make it prettier... but it's literally a call to Solid's `createComponent` with the Router and an anchoring div to which the Svelte component is mounted. Ezpz.

I'm also building an Anki clone (sigh) that I'm calling "Github for flashcards".

Very much a WIP, completely unusable, but I recently made a video demoing the technical proof of concept.

Anki, imo, already has an open algorithm (that the user can change via plugins), universal interfaces, and is "self-hosted". My eyes perked up at REST api, but it doesn't look like there's a centralized server that hosts shared cards, which is where my mind went.

I'm building https://github.com/AlexErrant/Pentive/ which is basically Anki + Reddit - people can optionally upload their cards for others to download, and the most popular cards rise to the top. It's FLOSS, offline-first, supports plugins and p2p syncing, and is very much a WIP. My proof of concept is almost done though, which demos the critical technologies in a secure way.

I'm using cr-sqlite right now in my Anki clone: https://github.com/AlexErrant/Pentive

It's basically an offline-first flashcard webapp. CR-Sqlite allows for incremental syncing.

With Anki (the app from which I'm taking my inspiration), syncing is _not_ incremental - basically it just copies SQLite files around. So for example, the app could be on an iPhone with cards a card `A` reviewed, but the app on an iPad could make changes to the template on which card `A` is based, and that's enough to cause a conflict - you must take changes from only the iPad or only the iPhone. (To be clear - Anki does have some incremental syncing capabilities - I'm picking an intentionally pathological example.) CR-SQLite will mean that everything is incremental, however.

Basically makes 3 way merges a breeze (or n-way merges, really).

A FLOSS, offline-first, spaced repetition system that has first class support for collaboration, curation, and plugins. It's Reddit for flashcards.

I've been thinking about this for a stupid amount of time... thinking that someday someone's going to improve on Anki. Finally got tired of it and said that person's me.
