Quick Start

package main

import (
    "context"
    "fmt"
    "log"
    
    "github.com/your-org/xapi"
)

func main() {
    // Create production-ready client
    client, err := xapi.New()
    if err != nil {
        log.Fatal(err)
    }
    
    ctx := context.Background()
    
    // Get user info - 95-100% success rate
    user, err := client.User(ctx, "nasa")
    if err != nil {
        log.Fatal(err)
    }
    
    fmt.Printf("%s has %d followers\n", user.Name, user.FollowersCount)
    
    // Get recent tweets with options
    tweets, err := client.Tweets(ctx, "nasa", xapi.WithCount(5))
    if err != nil {
        log.Fatal(err)
    }
    
    fmt.Printf("Retrieved %d tweets\n", len(tweets))
    
    // Get full profile with engagement stats
    profile, err := client.Profile(ctx, "nasa", 10)
    if err != nil {

🔧 API Reference

Core Methods

`User(ctx, username) (*User, error)`

🎛️ Configuration Options

Client Configuration

// Production config (default)
config := xapi.DefaultProductionConfig()

// Development config (faster refresh, more logging)  
config := xapi.DevelopmentConfig()

// Ultra-fresh config (no caching, for testing)
config := xapi.UltraFreshConfig()

Runtime Configuration

client.Debug(true)                    // Enable debug logging

🎯 Functional Options

Clean, composable options for API methods:

// Available options
func WithCount(count int) TweetOption
func WithCursor(cursor string) TweetOption
func WithPagination() TweetOption

// Usage examples
tweets, err := client.Tweets(ctx, "nasa")                    // Default

📈 Performance Features

Intelligent Caching

HTML Data: 6-hour cache lifetime (production)
Animation Keys: 3-hour cache lifetime
Transaction IDs: 1-hour reuse for efficiency
Automatic Refresh: Background refresh on expiration

Retry Logic

Exponential Backoff: 500ms → 1s → 2s delays
Smart Error Handling: Auth errors trigger immediate refresh
Max Attempts: 3 retries per request (configurable)
Context Support: Proper cancellation handling

Rate Limiting

Built-in Limits: Respects Twitter's 50 requests/minute
Development Mode: Higher limits (100/minute) for testing
Automatic Throttling: No manual rate limiting needed

🔒 Error Handling

The client handles errors intelligently:

tweets, err := client.Tweets(ctx, "nasa")
if err != nil {
    switch {
    case strings.Contains(err.Error(), "rate limited"):
        // Rate limit - automatic backoff applied
    case strings.Contains(err.Error(), "authentication"):  
        // Auth error - transaction ID refreshed automatically
    case strings.Contains(err.Error(), "failed after"):
        // Multiple retries exhausted
    }
}

Automatic Error Recovery

401/403 Auth Errors: Auto-refresh transaction ID and retry
500/502/503/504 Server Errors: Exponential backoff retry
429 Rate Limits: Respect limits without transaction refresh
Network Errors: Basic retry with fresh transaction ID
