Testing

This is awesome, especially for full-stack development! Leveraging JavaScript’s vast npm ecosystem makes this a really solid implementation. Looking forward to the official release! 🥳

Because I am really looking forward to the TypeScript bindings, I created a usability-enhancement plugin in my spare time to prepare for the future TypeScript version of spacetimedb. Experimental testing is already completed. If the TypeScript module bindings are further improved, I can continue to update this plugin.

before

import { registerReducer, registerType, type } from 'spacetimedb';

const Foo = registerType(
    'Foo',
    type.product({
        bar: type.f32,
        baz: type.string,
        count: type.i64
    })
);

registerReducer('beepboop', [type.array(type.f32), type.bool, Foo], (x, y, z) => {
    // z.bar;
});

after

import { useReducer, f32, bool, str, i64 } from 'spacetimedb/composable';

type Foo = {
    bar: f32,
    baz: str,
    count: i64,
}

useReducer('beepboop', (x: f32[], y: bool, z: Foo) => {
    // z.bar
});
