make build

Quick Start

1. Set up authentication:

   # Login with your private key
   grapevine auth login --alias my-account --key YOUR_PRIVATE_KEY
   
   # Or set environment variable
   export PRIVATE_KEY="your-private-key-here"

2. Create your first feed:

   grapevine feed create "My Feed" --description "My first content feed"

3. Add content to your feed:

   grapevine entry add FEED_ID "Hello world!" --title "My first entry"

# Add content to feed (free to view)
grapevine entry add FEED_ID "Content here" --title "Entry Title"

# Add paid content (costs to view)
grapevine entry add FEED_ID "Premium content" --title "Premium Entry" --paid --price 100000

# List entries in a feed
grapevine entry list FEED_ID --limit 5

# Get specific entry
grapevine entry get FEED_ID ENTRY_ID

# Batch add entries from JSON file
grapevine entry batch FEED_ID entries.json

# Delete entry
grapevine entry delete FEED_ID ENTRY_ID --force

Examples

Creating a Content Feed

# Set up authentication
export PRIVATE_KEY="0x..."

# Create feed
FEED_ID=$(grapevine feed create "Tech News" --description "Latest tech updates" | grep -o 'Feed created: [0-9a-f-]*' | cut -d' ' -f3)

# Add free content
grapevine entry add $FEED_ID "Breaking: New JavaScript framework released!" --title "JS Framework News"

# Add premium content  
grapevine entry add $FEED_ID "Detailed analysis of the framework..." --title "In-Depth Analysis" --paid --price 50000

echo "Feed created with ID: $FEED_ID"

Batch Content Upload

Create entries.json:

[
  {"content": "First batch entry", "title": "Entry 1"},
  {"content": "Second batch entry", "title": "Entry 2"},
  {"content": "Third batch entry", "title": "Entry 3"}
]

Upload:

grapevine entry batch FEED_ID entries.json --delay 100

Development

Prerequisites

• Go 1.21 or later

Building

# Build for current platform
make build

# Build for all platforms
make build-all

# Or directly with Go:
go build -o grapevine src/main.go

Testing

Unit Tests

# Run Go unit tests
make test

Integration Tests

Integration tests require a private key and make real API calls:

# Set your private key (for testnet testing)
export PRIVATE_KEY="your-private-key-here"

# Build the CLI
make build

# Run integration tests
./test/integration.sh

Note: Integration tests will:

• Create/delete feeds and entries on testnet
• Test all CLI commands end-to-end
• Require a funded testnet wallet
• Take 30-60 seconds to complete

Dependencies

The CLI uses these Go packages:

• github.com/spf13/cobra - Command-line interface framework
• github.com/spf13/viper - Configuration management
• github.com/ethereum/go-ethereum - Ethereum utilities for wallet operations

Architecture

The CLI is built as a single Go binary with the following key components:

1. Command Structure: Uses Cobra for command hierarchy and flag parsing
2. HTTP Client: Custom client for Grapevine API interactions
3. Authentication: Ethereum wallet integration for signing API requests
4. Configuration: JSON-based config file management
5. Cross-compilation: Builds native binaries for all major platforms

Performance Characteristics

• Binary size: ~8-15MB (optimized with -ldflags "-s -w")
• Startup time: <100ms
• Memory usage: ~10-20MB runtime
• Dependencies: Zero runtime dependencies (static binary)

Release Process

Binaries are built for:

• Linux (x64)
• macOS (x64 and ARM64)
• Windows (x64)

The build process creates optimized, stripped binaries for maximum performance and minimal size.
