Introduction to Cloud State
JavaScript has long been a staple in web development, but the introduction of Cloud State marks a significant shift in how developers approach building applications. Cloud State is a new JavaScript runtime that allows developers to write their entire application in TypeScript. This approach eliminates the need to juggle between different languages and frameworks, streamlining the development process.
Many developers might assume they are already using TypeScript for their entire stack, but often, there are layers like REST, HTTP, or GraphQL that operate outside of JavaScript. Cloud State aims to bring these components natively into TypeScript, reducing friction and increasing team efficiency.
Unified TypeScript Environment
Cloud State introduces a TypeScript engine that allows code to run as regular TypeScript, even within the database. This change means that data typically stored in memory can be persisted behind the scenes, removing the need for translation layers like Superbase or SQL.
With Cloud State, developers can write backend functions and call them directly from the frontend. This seamless integration allows for a more efficient workflow, reducing the complexity associated with connecting different parts of an application.
Building Applications with Freestyle
Freestyle takes the capabilities of Cloud State further. By using Freestyle, developers can write applications like a to-do list in pure TypeScript and have the data persist without a separate SQL database. The data persistence is handled directly within the TypeScript environment.
This approach simplifies the development process, allowing classes to transition from in-memory to persistent states with minimal effort. Developers can connect the front end to the backend by simply using TypeScript functions, maintaining strong typing throughout.
Handling Data Synchronization
One of the challenges with traditional development is managing data synchronization between the frontend and backend. Cloud State addresses this by introducing the use of "use cloud query," inspired by TAM stack. This handles loading and syncing data automatically, eliminating the need for manual refetching.
When changes occur in the backend, such as adding an item to a to-do list, Cloud State ensures that all dependent components are updated. This keeps the data consistent and synchronized across the application.
Deployment and Persistence
Deploying applications built with Cloud State is straightforward. Developers can build and deploy their apps with simple commands, and the data persistence infrastructure is included, supporting real functionality.
Cloud State's unique approach combines V8, Deno core, and a custom database engine. This combination allows for fine-grained transactions, breaking down objects into individual fields for efficient storage and retrieval.
Enabling Feature Sharing
Cloud State opens up new possibilities for sharing features as packages. Traditional JavaScript packages provide utilities, but Cloud State allows for sharing complete features, including data infrastructure.
Developers can create packages that encapsulate both frontend and backend logic, making it easy to share and reuse complex features like chat UIs without external dependencies. This approach democratizes feature sharing, making it accessible and manageable for developers.
Conclusion
Cloud State represents a significant evolution in how applications are developed and deployed. By unifying the entire stack within TypeScript, it eliminates the complexities associated with multiple languages and frameworks. This unified approach not only increases efficiency but also opens new avenues for feature sharing and collaboration among developers. As JavaScript continues to evolve, Cloud State positions itself as a key player in shaping the future of application development.
