# Rate Limiting Example

This example demonstrates how the rate limiter works with the TMDB library.

```typescript
// Custom rate limiter for different use cases
import TMDB, { RateLimiter, rateLimiter } from '@odyssoft/tmdb'

async function example() {
  const tmdb = TMDB('your-api-key')

  console.log('Making 45 rapid requests to test rate limiting...')
  console.log('Rate limit: 40 requests per 10 seconds')

  const startTime = Date.now()

  // Make 45 requests (5 more than the limit)
  const promises = []
  for (let i = 0; i < 45; i++) {
    promises.push(
      tmdb.Search.Movies({ query: `test-${i}` })
        .then(() => {
          console.log(
            `Request ${i + 1} completed at ${Date.now() - startTime}ms`
          )
        })
        .catch((err) => {
          console.log(`Request ${i + 1} failed:`, err.message)
        })
    )
  }

  await Promise.all(promises)

  const endTime = Date.now()
  console.log(`All requests completed in ${endTime - startTime}ms`)
  console.log(`Current rate limiter count: ${rateLimiter.getCurrentCount()}`)
}

// Access rate limiter directly for monitoring
function checkRateLimiter() {
  console.log('Rate Limiter Status:')
  console.log(`Current count: ${rateLimiter.getCurrentCount()}`)
  console.log(`Time until next slot: ${rateLimiter.getTimeUntilNextSlot()}ms`)
}

const customLimiter = new RateLimiter(10, 5000) // 10 requests per 5 seconds

async function customRateLimitExample() {
  console.log('Using custom rate limiter...')

  for (let i = 0; i < 15; i++) {
    await customLimiter.waitForSlot()
    console.log(`Custom request ${i + 1} allowed`)
  }
}
```

## Key Features

1. **Automatic Rate Limiting**: All API requests are automatically rate-limited to 40 requests per 10 seconds
2. **Configurable**: You can create custom rate limiters with different limits
3. **Monitoring**: Check current status and time until next available slot
4. **Concurrent Safe**: Handles multiple concurrent requests correctly
5. **Memory Efficient**: Automatically cleans up expired request timestamps

## Rate Limiter Methods

- `waitForSlot()`: Wait for an available request slot
- `getCurrentCount()`: Get current number of requests in time window
- `getTimeUntilNextSlot()`: Get milliseconds until next slot is available
- `reset()`: Clear all tracked requests
