Chapter 2: Your First SpaceTimeDB Project: Setup and Workflow

Welcome back, aspiring real-time architect! In Chapter 1, we explored the “why” behind SpaceTimeDB, understanding its unique approach to unifying database, backend logic, and real-time synchronization. Now, it’s time to roll up our sleeves and dive into the “how.”

This chapter is your hands-on initiation into the SpaceTimeDB universe. We’ll guide you through setting up your development environment, creating your very first SpaceTimeDB project, defining a simple database schema, and writing server-side logic that modifies your data. By the end, you’ll have a running SpaceTimeDB instance on your local machine, ready to power real-time applications. Get ready to build, learn, and have some fun!

Chapter 4: Querying Your Data: Retrieving and Filtering Information

Sat, 14 Mar 2026 00:00:00 +0000

Introduction

Welcome back, future SpaceTimeDB master! In the previous chapter, you learned how to define your database schema and create tables to store your application’s shared state. You even got a taste of how to add data to these tables using reducers. But what good is storing data if you can’t get it back out?

This chapter is all about querying your data. We’ll dive into how clients can ask SpaceTimeDB for specific pieces of information and how that information is kept up-to-date in real-time. We’ll explore the unique subscription model that makes SpaceTimeDB so powerful for real-time applications, and also touch upon how server-side logic (like your reducers) can access and filter data. By the end of this chapter, you’ll be able to retrieve exactly the data you need, when you need it, and react to changes instantly.

Chapter 5: Bringing Logic to Life: Reducers and Server-Side Operations

Sat, 14 Mar 2026 00:00:00 +0000

Introduction: Where the Magic Happens – Server-Side Logic

Welcome back, intrepid SpaceTimeDB explorer! In our previous chapters, we laid the groundwork by understanding SpaceTimeDB’s unique architecture, setting up our environment, and defining our database schema with tables. You now know how to structure your data, but what about changing it? How do you update a player’s score, add a new chat message, or move a character in a game?

This is where server-side logic comes into play, and in SpaceTimeDB, it’s handled by a powerful concept called Reducers. Reducers are the heart of your application’s state changes, ensuring that all modifications to your shared database are consistent, deterministic, and immediately propagated to all connected clients.

Chapter 6: Real-time Magic: Client Synchronization and Event Propagation

Chapter 6: Real-time Magic: Client Synchronization and Event Propagation

Welcome back, intrepid developer! In our previous chapters, we’ve explored the foundational concepts of SpaceTimeDB, from setting up your development environment to designing schemas and writing server-side logic using reducers. We’ve seen how SpaceTimeDB acts as a unified backend, combining a database with application logic.

Now, it’s time to unveil the “magic” that makes SpaceTimeDB truly shine: its real-time capabilities. This chapter will pull back the curtain on how client applications stay perfectly synchronized with your SpaceTimeDB instance, receiving instant updates as data changes. We’ll explore the core mechanisms of client synchronization, event propagation, and how to build responsive, collaborative experiences.

Chapter 7: Building Collaborative Features: Patterns for Shared State

Chapter 7: Building Collaborative Features: Patterns for Shared State

Welcome back, intrepid developer! In our journey through SpaceTimeDB, we’ve covered the basics of setting up your database, defining schemas, and even writing server-side logic with reducers. But where SpaceTimeDB truly shines is in its ability to power real-time, collaborative applications. This is where the magic of shared state and instant synchronization comes alive!

In this chapter, we’re going to dive deep into building collaborative features. We’ll explore the patterns and techniques that allow multiple users to interact with the same data simultaneously, seeing updates happen in real-time across all connected clients. Think multiplayer games, shared whiteboards, collaborative document editors, or live dashboards – SpaceTimeDB makes these complex scenarios surprisingly approachable. Get ready to build applications that feel alive and responsive!

Chapter 9: Ensuring Consistency: Concurrency, Transactions, and Determinism

Chapter 9: Ensuring Consistency: Concurrency, Transactions, and Determinism

Welcome to Chapter 9! So far, we’ve explored how SpaceTimeDB combines database, backend logic, and real-time synchronization. We’ve built schemas, written reducers, and seen how clients react to state changes. But as applications grow and multiple users interact simultaneously, a critical question arises: How does SpaceTimeDB keep everything consistent and reliable?

In this chapter, we’re going to pull back the curtain on some of SpaceTimeDB’s most powerful, yet often invisible, features: concurrency control, transactional integrity, and deterministic execution. These are the bedrock upon which SpaceTimeDB builds its promise of “multiplayer at the speed of light.” Understanding these concepts is vital for designing robust, bug-free real-time systems that behave predictably, no matter how many users are interacting at once. Get ready to explore the “why” and “how” behind SpaceTimeDB’s impressive consistency guarantees!

Chapter 16: Schema Evolution, Migrations, and Advanced Design Patterns

Sat, 14 Mar 2026 00:00:00 +0000

Introduction

Welcome to Chapter 16! So far, we’ve explored the core concepts of SpaceTimeDB, built real-time applications, and even delved into performance and security. But what happens when your application grows, and your initial data model no longer fits your evolving needs? This is where schema evolution and data migrations come into play.

In this chapter, we’ll tackle the crucial, yet often overlooked, aspects of managing change in your SpaceTimeDB projects. We’ll learn how to gracefully adapt your database schema over time without disrupting existing data or live applications. We’ll also explore different strategies for migrating data when your schema changes require transforming existing information. Finally, we’ll dive into advanced design patterns like Event Sourcing and CQRS, showing how SpaceTimeDB’s unique architecture naturally supports them, helping you build even more robust and scalable systems.
