# Adding New Proto Files
## Step-by-Step Guide
### 1. Create the new .proto file
Create `platform_shared/myfeature.proto`:
```protobuf
syntax = "proto3";
package socket_message;
message MyFeatureRequest {
string name = 1;
}
message MyFeatureResponse {
bool success = 1;
string error = 2;
}
```
### 2. Create the .options file (for nanopb size constraints)
Create `platform_shared/myfeature.options`:
```
socket_message.MyFeatureRequest.name max_size:64
socket_message.MyFeatureResponse.error max_size:128
```
### 3. Import in message.proto
Add the import at the top of `platform_shared/message.proto`:
```protobuf
import "myfeature.proto";
```
### 4. Add to Message oneof (if needed for streaming/pub-sub)
If your message needs to be sent directly (not via correlation request/response), add it to the `Message` oneof in `message.proto`:
```protobuf
message Message {
oneof message {
// ... existing fields ...
MyFeatureRequest my_feature_request = 300; // Pick unused tag number
MyFeatureResponse my_feature_response = 301;
}
}
```
### 5. Add to CorrelationRequest/Response (if using request/response pattern)
For request/response messages, add to the correlation oneofs in `message.proto`:
```protobuf
message CorrelationRequest {
oneof request {
// ... existing fields ...
MyFeatureRequest my_feature_request = 200; // Pick unused tag number
}
}
message CorrelationResponse {
oneof response {
// ... existing fields ...
MyFeatureResponse my_feature_response = 200;
}
}
```
### 6. Update compile scripts
**ESP32 (esp32/scripts/compile_protos.py):**
```python
proto_files = [proto_dir / "filesystem.proto", proto_dir / "myfeature.proto", proto_dir / "message.proto"]
```
**TypeScript (app/scripts/compile_protos.js):**
```javascript
const protoFiles = ['filesystem.proto', 'myfeature.proto', 'message.proto']
```
### 7. Update socket.ts (for TypeScript - only if added to Message oneof)
If you added messages to the `Message` oneof, import the protoMetadata in `app/src/lib/stores/socket.ts`:
```typescript
import { protoMetadata as myfeatureProtoMetadata } from '$lib/platform_shared/myfeature'
// Add to combinedReferences
const combinedReferences: Record<string, MessageFns<unknown>> = {
...protoMetadata.references,
...filesystemProtoMetadata.references,
...myfeatureProtoMetadata.references // Add this
}
```
### 8. Add MessageTraits (for ESP32 - only if added to Message oneof)
If you added messages to the `Message` oneof, add traits in `esp32/include/communication/proto_helpers.h`:
```cpp
// Before #undef DEFINE_MESSAGE_TRAITS
DEFINE_MESSAGE_TRAITS(MyFeatureRequest, my_feature_request)
DEFINE_MESSAGE_TRAITS(MyFeatureResponse, my_feature_response)
```
### 9. Build and test
```bash
# ESP32
pio run
# TypeScript
cd app && pnpm proto
```
## Quick Reference
| File | Purpose |
|------|---------|
| `platform_shared/*.proto` | Protocol definitions |
| `platform_shared/*.options` | Nanopb size constraints |
| `esp32/scripts/compile_protos.py` | ESP32 proto compilation |
| `app/scripts/compile_protos.js` | TypeScript proto compilation |
| `app/src/lib/stores/socket.ts` | Tag mapping for socket.on/emit |
| `esp32/include/communication/proto_helpers.h` | MessageTraits for ESP32 emit |
## Notes
- Messages in `CorrelationRequest/Response` don't need MessageTraits or socket.ts updates
- Messages in `Message` oneof (for streaming/pub-sub) need both
- Always use the same `package socket_message;` in all proto files
- Tag numbers in oneofs must be unique across all fields
