Flightpath Protocol Definitions

Protocol Buffer definitions for the Flightpath drone control platform.

Overview

This repository contains the API contract definitions for Flightpath, a protocol-agnostic, multi-drone ground control system. The generated code is published as:

• Go module: github.com/flightpath-dev/flightpath-proto - importable by Go projects
• npm package: @flightpath/flightpath-proto - importable by TypeScript/JavaScript projects

Services

ConnectionService

Manages drone connection lifecycle and health monitoring.

ControlService

Flight control commands (arm, takeoff, land, navigation).

TelemetryService

Real-time telemetry streaming (position, attitude, battery, etc.).

MissionService

Autonomous mission planning and execution.

FileStorageService

Server-side configuration and mission storage.

Using the Go Module

This repository publishes generated Go code as a Go module that can be imported by other Go projects.

Installation

Add the module to your Go project:

go get github.com/flightpath-dev/flightpath-proto@latest

Or specify a specific version:

go get github.com/flightpath-dev/flightpath-proto@v1.0.0

Importing

Import the generated code in your Go files:

import (
    "github.com/flightpath-dev/flightpath-proto/gen/go/drone/v1"
    "github.com/flightpath-dev/flightpath-proto/gen/go/drone/v1/dronev1connect"
)

Example Usage

package main

import (
    "context"
    "log"
    "net/http"
    "github.com/flightpath-dev/flightpath-proto/gen/go/drone/v1"
    "github.com/flightpath-dev/flightpath-proto/gen/go/drone/v1/dronev1connect"
    "connectrpc.com/connect"
)

func main() {
    // Use the generated types
    position := &dronev1.Position{
        Latitude:  37.7749,
        Longitude: -122.4194,
        AltitudeMsl: 100.0,
    }
    
    // Use the generated Connect clients
    client := dronev1connect.NewConnectionServiceClient(
        http.DefaultClient,
        "https://api.example.com",
    )
    
    // Make RPC calls
    resp, err := client.Connect(context.Background(), connect.NewRequest(&dronev1.ConnectRequest{
        DroneId: "drone-001",
    }))
    if err != nil {
        log.Fatal(err)
    }
    // Use resp...
    _ = position
    _ = resp
}

Using the TypeScript/JavaScript Package

This repository publishes generated TypeScript/JavaScript code as an npm package that can be imported by other TypeScript/JavaScript projects.

Installation

Install the package using npm:

npm install @flightpath/flightpath-proto

Or using yarn:

yarn add @flightpath/flightpath-proto

Or using pnpm:

pnpm add @flightpath/flightpath-proto

Importing

Import the generated code in your TypeScript/JavaScript files:

import { ConnectionService } from '@flightpath/flightpath-proto/gen/ts/drone/v1/connection_connect.js';
import { ConnectRequest, ConnectResponse } from '@flightpath/flightpath-proto/gen/ts/drone/v1/connection_pb.js';
import { Position } from '@flightpath/flightpath-proto/gen/ts/drone/v1/types_pb.js';

Example Usage

import { createPromiseClient } from '@connectrpc/connect';
import { createConnectTransport } from '@connectrpc/connect-web';
import { ConnectionService } from '@flightpath/flightpath-proto/gen/ts/drone/v1/connection_connect.js';
import { ConnectRequest } from '@flightpath/flightpath-proto/gen/ts/drone/v1/connection_pb.js';
import { Position } from '@flightpath/flightpath-proto/gen/ts/drone/v1/types_pb.js';

// Create a transport
const transport = createConnectTransport({
  baseUrl: 'https://api.example.com',
});

// Create a client
const client = createPromiseClient(ConnectionService, transport);

// Use the generated types
const position: Position = {
  latitude: 37.7749,
  longitude: -122.4194,
  altitudeMsl: 100.0,
};

// Make RPC calls
const response = await client.connect({
  droneId: 'drone-001',
  timeoutMs: 5000,
});

console.log('Connected:', response.success);

• Client (React/TypeScript): https://github.com/flightpath-dev/flightpath-client

Development

Prerequisites

• Buf CLI
• Go 1.21 or later (for Go code generation)
• Node.js 20 or later (for TypeScript code generation and npm publishing)

Linting

buf lint

Code Generation for Go

buf generate --template buf.gen.go.yaml

Generates code to gen/go/ with the correct import paths for the published module.

Important: After generating code, commit the generated files to the repository.

Go Module Dependencies

Important: The module path in go.mod and the go_package prefix in buf.gen.go.yaml must match the repository name. The import paths in the generated code must match the actual file locations in the repository.

After first publish:

• You can run go mod tidy to update dependencies and go.sum
• Commit the updated go.sum file.

Code Generation for TypeScript

buf generate --template buf.gen.ts.yaml

Generates code to gen/ts/ with the correct import paths for the published npm package.

Important: After generating code, commit the generated files to the repository.

Breaking Change Detection

buf breaking --against '.git#branch=main'

Releasing New Versions

This repository uses semantic versioning (v1.0.0, v1.1.0, etc.) and manual releases.

Release Process

1. Make your changes to the proto files in the drone/v1/ directory

2. Test locally:

   buf lint
   buf breaking --against '.git#branch=main'

3. Generate code:

   buf generate --template buf.gen.go.yaml
   buf generate --template buf.gen.ts.yaml

4. Update version (if needed):

   • Update package.json version for npm releases
   • The Go module version is determined by the git tag

5. Commit all changes:

   git add drone/v1/ gen/go/ gen/ts/ package.json
   git commit -m "feat: add new field to ConnectionRequest"

6. If this is after the first publish, update go.sum:

   go mod tidy
   git add go.sum
   git commit -m "chore: update go.sum"

7. Create and push the tag:

   git tag -a v1.1.0 -m "Release v1.1.0"
   git push origin main
   git push origin v1.1.0

8. Publish to npm (if needed):

   npm publish --access public

9. Users can then update:

   Go:

   go get github.com/flightpath-dev/flightpath-proto@v1.1.0

   TypeScript/JavaScript:

   npm install @flightpath/flightpath-proto@1.1.0

Versioning Guidelines

• MAJOR (v2.0.0): Breaking changes to the API
• MINOR (v1.1.0): New features, backward compatible
• PATCH (v1.0.1): Bug fixes, backward compatible

Publishing to npm

To publish the package to npm:

1. Log in to npm (if not already):

   npm login

2. Publish the package:

   npm publish --access public

   Make sure the version in package.json matches your git tag (without the v prefix).
