Welcome, Developer! (A Simple Guide to Protobuf & TypeScript)

In the fast-paced world of modern software development, efficient communication between different parts of an application is crucial. Imagine your web browser (the "front-end") needing to talk to a powerful server (the "back-end"). They need to speak the same language. **Protocol Buffers (Protobuf)**, developed by Google, is a super-efficient language for defining the structure of your data. You write a simple "schema" in a `.proto` file, which acts as a universal blueprint. From this blueprint, you can generate code in any programming language, ensuring your back-end server and front-end application always agree on what the data looks like. It's like having a universal translator for your application's data.

On the front-end, we often use **TypeScript** to build robust and bug-free applications. A key feature of TypeScript is the **Interface**, which is like a "code contract" or a template for our data. It defines the exact shape an object should have, catching errors before they ever happen. When your back-end speaks Protobuf and your front-end speaks TypeScript, you need to make sure your TypeScript Interfaces perfectly match your Protobuf schema. Manually keeping these two in sync can be tedious, boring, and prone to human error. This tool is designed to be your expert translator, instantly and perfectly converting your `.proto` schema into clean, ready-to-use TypeScript interfaces. It's an essential utility for streamlining your workflow, preventing bugs, and maintaining perfect harmony between your client and server.

How to Use This Converter

1. Paste Your Protobuf Schema: In the "Protobuf Input" editor on the left, paste the contents of your `.proto` file. You can include multiple `message` and `enum` definitions. Your work is automatically saved in your browser!
2. See the Live Conversion: As you type, the "TypeScript Interface Output" panel on the right will instantly update with the generated interfaces. There's no "convert" button—it all happens in real-time.
3. Copy, Share, and Use: Once you're happy with the result, click the **"Copy Code"** button to copy the interfaces to your clipboard. If you want to save your schema or share it with a colleague, click the **"Copy Share Link"** button to generate a unique URL for your exact input.

Tips for Best Results

• Understands Common Types:** This tool correctly maps all standard Protobuf scalar types (`string`, `int32`, `bool`, `float`, etc.) to their corresponding TypeScript types (`string`, `number`, `boolean`). It also handles `bytes`, converting it to the standard `Uint8Array` type in TypeScript.
• Handles `repeated` Fields:** Fields marked as `repeated` in your Protobuf schema are the equivalent of lists or arrays. This tool will correctly convert them to array types in TypeScript. For example, `repeated string tags` becomes `tags: string[];`.
• Nested Messages and Enums:** The converter is smart enough to correctly handle `message` and `enum` definitions that are nested inside other messages. It will generate the appropriate structures, ensuring your complex data types are accurately represented.
• Client-Side and Secure:** For your security and privacy, this tool does all of its work directly in your web browser. Your schemas and code are never uploaded to any server, making the process instant and completely private. Your work is only saved to your own browser's local storage.
