Each file could be a SQLSync database, enabling real-time local first collaboration and presence - Running SQLSync on the edge with high tolerance for unreliable network conditions - Enabling optimistic mutations on SQLite read replicas **SQLSync Demo** The best way to get a feel for how SQLSync behaves is to play with the [Todo list demo][todo-demo]. Clicking [this link][todo-demo] will create a unique to-do list and redirect you to its unique URL. You can then share that URL with friends or open it on multiple devices (or browsers) to see the power of offline-first collaborative SQLite. [todo-demo]: https://sqlsync-todo.pages.dev/ You can also learn more about SQLSync and it's goals by watching Carl's WasmCon 2023 talk. [The recording can be found here][wasmcon-talk]. [wasmcon-talk]: https://youtu.be/oLYda9jmNpk?si=7BBBdLxEj9ZQ4OvS **Features** - Eventually consistent SQLite - Optimistic reads and writes - Reactive query subscriptions - Real-time collaboration - Offline-first - Cross-tab sync - React library If you are interested in using or contributing to SQLSync, please [join the Discord community][discord] and let us know what you want to build. We are excited to collaborate with you! ## Installation & Getting started Please refer to [the guide](./GUIDE.md) to learn how to add SQLSync to your application. ## Tips & Tricks ### How to debug SQLSync in the browser By default SQLSync runs in a shared web worker. This allows the database to automatically be shared between different tabs, however results in making SQLSync a bit harder to debug. The easiest way is to use Google Chrome, and go to the special URL: [chrome://inspect/#workers](chrome://inspect/#workers). On that page you'll find a list of all the running shared workers in other tabs. Assuming another tab is running SQLSync, you'll see the shared worker listed. Click `inspect` to open up dev-tools for the worker. ### My table is missing, or multiple statements aren't executing SQLSync uses [rusqlite] under the hood to run and query SQLite. Unfortunately, the `execute` method only supports single statements and silently ignores trailing statements. Thus, if you are using `execute!(...)` in your reducer, make sure that each call only runs a single SQL statement. For example: ```rust // DON'T DO THIS: execute!("create table foo (id int); create table bar (id int);").await?; // DO THIS: execute!("create table foo (id int)").await?; execute!("create table bar (id int)").await?; ``` ## Community & Contributing If you are interested in contributing to SQLSync, please [join the Discord community][discord] and let us know what you want to build. All contributions will be held to a high standard, and are more likely to be accepted if they are tied to an existing task and agreed upon specification.
