SpacetimeDB TypeScript Quickstart Chat

This is a simple chat application that demonstrates how to use SpacetimeDB with TypeScript and React. The chat application is a simple chat room where users can send messages to each other. The chat application uses SpacetimeDB to store the chat messages.

It is based directly on the plain React + TypeScript + Vite template. You can follow the quickstart guide for how creating this project from scratch at SpacetimeDB TypeScript Quickstart.

You can follow the instructions for creating your own SpacetimeDB module here: SpacetimeDB Rust Module Quickstart. Place the module in the quickstart-chat/server directory for compability with this project.

In order to run this example, you need to:

• pnpm build in the root directory (spacetimedb-typescriptsdk)
• pnpm install in this directory
• pnpm build in this directory
• pnpm dev in this directory to run the example

Below is copied from the original template README:

React + TypeScript + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

• @vitejs/plugin-react uses Babel for Fast Refresh
• @vitejs/plugin-react-swc uses SWC for Fast Refresh

Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:

• Configure the top-level parserOptions property like this:

export default tseslint.config({
  languageOptions: {
    // other options...
    parserOptions: {
      project: ['./tsconfig.node.json', './tsconfig.app.json'],
      tsconfigRootDir: import.meta.dirname,
    },
  },
});

• Replace tseslint.configs.recommended to tseslint.configs.recommendedTypeChecked or tseslint.configs.strictTypeChecked
• Optionally add ...tseslint.configs.stylisticTypeChecked
• Install eslint-plugin-react and update the config:

// eslint.config.js
import react from 'eslint-plugin-react';

export default tseslint.config({
  // Set the react version
  settings: { react: { version: '18.3' } },
  plugins: {
    // Add the react plugin
    react,
  },
  rules: {
    // other rules...
    // Enable its recommended rules
    ...react.configs.recommended.rules,
    ...react.configs['jsx-runtime'].rules,
  },
});
