Welcome to the world of Triplit! This open-source database empowers developers to sync data seamlessly between servers and browsers in real time. If you’re looking to integrate a robust database solution into your application, this guide will help you step by step, providing easy-to-follow instructions and troubleshooting tips.

What is Triplit?

Triplit is a revolutionary “full stack database” which allows you to interact with your data both on the server-side and client-side, effectively syncing everything in real-time. It excels in:

• Real-time sync with incremental updates
• Local caching using a full-fledged client-side database
• Durable server-side storage with an admin dashboard
• Pluggable storage providers like SQLite and IndexedDB
• Optimistic updates for fast user interactions
• Offline mode with automatic reconnections
• Collaboration features using CRDTs (Conflict-free Replicated Data Types)

Setting Up Your Triplit Application

Here’s a user-friendly walkthrough to set up your application using Triplit:

1. Starting a New Project

Run the following command in your terminal:

npm create triplit-app@latest my-app

2. Adding Dependencies to an Existing Project

You can add Triplit to an existing project with:

npm install --save-dev @triplit/client

npm run triplit init

3. Define a Schema

Use the following TypeScript code to define a schema for your app:

import Schema as S, ClientSchema from @triplit/client;
export const schema = {
  todos: {
    schema: S.Schema({
      id: S.Id(),
      text: S.String(),
      completed: S.Boolean({ default: false }),
    }),
  },
} satisfies ClientSchema;

4. Starting the Triplit Development Sync Server

Run the command below to start the server:

npm run triplit dev

This command will output some important environmental variables needed for syncing. Make sure to add them to your .env file, like so:

VITE_TRIPLIT_SERVER_URL=http://localhost:6543
VITE_TRIPLIT_TOKEN=copied-in-from-triplit-dev

5. Defining a Query

Now let’s set up a query in your React app:

import TriplitClient from @triplit/client;
import useQuery from @triplit/react;
import schema from '../triplit/schema';

const client = new TriplitClient(schema, {
  serverUrl: import.meta.env.VITE_TRIPLIT_SERVER_URL,
  token: import.meta.env.VITE_TRIPLIT_TOKEN,
});

function App() {
  const results: todos = useQuery(client.query(todos));
  return (
    

      {Array.from(todos.values()).map((todo) => (
        

          
              client.update(todos, todo.id, (todo) => {
                todo.completed = !todo.completed;
              })
            }
          />
          {todo.text}
        
      ))}
    
  );
}

6. Sync Up in Real-Time

Run your app, open another browser tab, and watch the data sync in real-time!

Troubleshooting

If you encounter any issues along the way, here are some troubleshooting steps:

• Ensure that all commands are run from the correct project directory.
• Check your environmental variables for typos and proper formatting.
• Make sure the Triplit development server is running before launching the app.
• Consult the Triplit documentation for in-depth guidance.
