By loading a `FileDescriptorSet` at runtime, gRab acts as a bridge between human-readable JSON and binary Protobuf wire format. + +It is heavily inspired by tools like `grpcurl` but built to leverage the safety and performance of the Rust ecosystem (Tonic + Prost). + +## 🚀 Features + +* **Dynamic Encoding/Decoding**: Transcodes JSON to Protobuf (and vice versa) on the fly using `prost-reflect`. +* **Smart Dispatch**: Automatically detects if a call is Unary, Server Streaming, Client Streaming, or Bidirectional based on the descriptor. +* **Fast Fail Validation**: Validates your JSON *before* hitting the network. +* **Zero Compilation Dependencies**: Does not require generating Rust code for your protos. Just point to a descriptor file. +* **Metadata Support**: Easily attach custom headers (authorization, tracing) to your requests. +* **Tonic 0.14**: Built on the latest stable Rust gRPC stack. + +## 📦 Installation + +### From Source + +Ensure you have Rust and Cargo installed. + +```bash +git clone https://github.com/JasterV/grab +cd grab +cargo install --path . +``` + +## 🛠️ Prerequisites: Generating Descriptors + +To use gRab, you currently need a binary **FileDescriptorSet** (`.bin` or `.pb`). This file contains the schema definitions for your services. + +You can generate this using the standard `protoc` compiler: + +```bash +# Generate descriptor.bin including all imports +protoc \ + --include_imports \ + --descriptor_set_out=descriptor.bin \ + --proto_path=. \ + my_service.proto + +``` + +> **Note**: The `--include_imports` flag is crucial. It ensures that types defined in imported files (like `google/protobuf/timestamp.proto`) are available for reflection. + +## 📖 Usage + +**Syntax:** + +```bash +grab [OPTIONS] + +``` + +### Arguments + +| Argument | Description | Required | +| --- | --- | --- | +| `` | Server address (e.g., `http://[::1]:50051`). | **Yes** | +| `` | Fully qualified method name (e.g., `my.package.Service/Method`). | **Yes** | + +### Options + +| Flag | Short | Description | Required | +| --- | --- | --- | --- | +| `--proto-set` | | Path to the binary FileDescriptorSet (`.bin`). | **Yes** | +| `--body` | | The request body in JSON format. | **Yes** | +| `--header` | `-H` | Custom header `key:value`. Can be used multiple times. | No | + +### JSON Body Format + +* **Unary / Server Streaming**: Provide a single JSON object `{ ... }`. +* **Client / Bidirectional Streaming**: Provide a JSON array of objects `[ { ... }, { ... } ]`. + +### Examples + +**1. Unary Call** + +```bash +grab \ + --proto-set ./descriptor.bin \ + --body '{"name": "Ferris"}' \ + http://localhost:50051 \ + helloworld.Greeter/SayHello +``` + +**2. Bidirectional Streaming (Chat)** + +```bash +grab \ + --proto-set ./descriptor.bin \ + --body '[{"text": "Hello"}, {"text": "How are you?"}]' \ + -H "authorization: Bearer token123" \ + http://localhost:50051 \ + chat.ChatService/StreamMessages +``` + +## 🔮 Roadmap + +* **Automatic Server Reflection**: We are working on removing the requirement for the `--proto-set` file. Future versions will support fetching the schema directly from servers that have the [gRPC Server Reflection Protocol](https://github.com/grpc/grpc/blob/master/doc/server-reflection.md) enabled. +* **Interactive Mode**: A REPL for streaming requests interactively. +* **Pretty Printing**: Enhanced colored output for JSON responses. + +## ⚠️ Common Errors + +**1. `Service 'x' not found**` + +* **Cause:** The service name in the command does not match the package defined in your proto file. +* **Fix:** Check your `.proto` file. If it has `package my.app;` and `service API {}`, the full name is `my.app.API`. + +**2. `Method 'y' not found in service 'x'**` + +* **Cause:** Typo in the method name or the method doesn't exist. +* **Fix:** Ensure case sensitivity matches (e.g., `GetUser` vs `getUser`). + +**3. `h2 protocol error**` + +* **Cause:** This often occurs when the JSON payload fails to encode *after* the connection has already been established, or the server rejected the stream structure. +* **Fix:** Double-check your JSON payload against the Protobuf schema. + +## 🤝 Contributing + +Contributions are welcome!
