Quick Start

The simplest way to get started: 

package main

import (
	"context"
	"fmt"
	"log"

	"github.com/Davincible/xapi"
)

func main() {
	// Create client with production defaults
	client, err := xapi.New()
	if err != nil {
		log.Fatal(err)
	}

	ctx := context.Background()

	// Get user profile
	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
	tweets, err := client.Tweets(ctx, "nasa", xapi.WithCount(5))
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("Retrieved %d tweets\n", len(tweets))
}

Configuration

The client supports three configuration modes:

Production mode (default): 

client, err := xapi.New()

Development mode (faster refresh, more logging): 

client, err := xapi.NewDevelopmentClient()

Custom configuration: 

config := &xapi.ProductionConfig{
	HTMLDataCacheLifetime: 12 * time.Hour,  // Custom cache duration
	EnableDebugLogging:    true,             // Enable debug logs
	MaxRetryAttempts:      5,                // More retries
}
client, err := xapi.NewClient(config)

API Endpoints

The client provides access to 12 Twitter API endpoints:

Core endpoints:

  • User() - Get user profile information
  • Tweets() / TweetsPage() - Fetch user tweets with pagination
  • Tweet() - Get single tweet by ID
  • Profile() - Complete user profile with tweets and statistics

Social graph endpoints:

  • Following() - Users that a user follows
  • Followers() - A user's followers
  • BlueVerified() - Blue verified followers only

Content endpoints:

  • Highlights() - User's highlighted/pinned tweets
  • Broadcast() - Live broadcast/stream information
  • UserBusiness() - Business profile team timeline

Utility endpoints:

  • UsersByIDs() - Bulk user lookup

Functional Options

Many methods support functional options for customization: 

// Get 10 tweets instead of default 20
tweets, err := client.Tweets(ctx, "nasa", xapi.WithCount(10))

// Use pagination
page, err := client.TweetsPage(ctx, "nasa", xapi.WithCount(20))
if page.HasMore {
	nextTweets, err := client.Tweets(ctx, "nasa",
		xapi.WithCursor(page.NextCursor.Value))
}

Error Handling

The client implements intelligent error handling with automatic retry: 

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

Tweets fetches a user's recent tweets with high reliability (95-100% success rate).

This method fetches up to 20 tweets by default, but can be customized using functional options. The username can include or omit the "@" prefix.

Parameters:

  • ctx: Context for request cancellation and timeouts
  • username: Twitter username (with or without "@" prefix)
  • options: Optional functional options (WithCount, WithCursor, etc.)

Returns a slice of Tweet objects containing full text, engagement metrics, creation time, and other metadata. May return fewer tweets than requested if the user has limited public content.

Example: 

// Get default 20 tweets
tweets, err := client.Tweets(ctx, "nasa")

// Get 5 tweets with custom count
tweets, err := client.Tweets(ctx, "@nasa", xapi.WithCount(5))

// Paginate through tweets
page, err := client.TweetsPage(ctx, "nasa")
if page.HasMore {
    moreTweets, err := client.Tweets(ctx, "nasa",
        xapi.WithCursor(page.NextCursor.Value))
}

func (*Client) TweetsPage 

func (c *Client) TweetsPage(ctx context.Context, username string, options ...TweetOption) (*TweetPage, error)
