The end of 1.0 is nigh! 🤩

v1.12 will be the last minor version before we drop SpacetimeDB 2.0! SpacetimeDB 2.0 will come with code breaking changes (you may need to change your modules and clients), but it will not require a migration of the existing data directory, and include backwards compatibility with existing clients and modules, so all existing databases and modules will continue working on both Standalone deploys and Maincloud.

If you're not subscribed to our YouTube channel, you should be. Trust me on that one.

We've got some great updates today in v1.12!

Typed Query Builder

• Added a typed query builder for the TypeScript client. (#4021)
• Added a Rust client query builder. (#4003)
• Added a typed query builder for the C# client, plus additional regression coverage. (#3982, #4123)

You can now subscribe to your server's data with type safe queries from clients:

TypeScript

import { queries } from "./module_bindings";
conn.subscriptionBuilder().subscribe([queries.user.build()]);

C#

conn.SubscriptionBuilder().AddQuery(ctx => ctx.From.User().Build()).Subscribe();

Rust

conn.subscription_builder().add_query(|ctx| ctx.from.user().build()).subscribe();

NOTE: We would like to remove the .build() for 2.0, but you can try it out with the existing API.
