Advanced Features

SpanBuilder for Time Arithmetic

# Future events
span = SpanBuilder.now_plus(7, TimeUnit.DAYS)        # Next 7 days
span = SpanBuilder.now_plus(2, TimeUnit.MONTHS)      # Next 2 months
span = SpanBuilder.now_to_future()                   # All future events

# Past events (⚠️ may cause server errors)
span = SpanBuilder.now_minus(30, TimeUnit.DAYS)      # Last 30 days
span = SpanBuilder.now_minus(6, TimeUnit.HOURS)      # Last 6 hours

# Custom ranges
span = SpanBuilder.range(
    start_offset=7, 
    start_unit=TimeUnit.DAYS,
    end_offset=60, 
    end_unit=TimeUnit.DAYS
)  # Between 1 week and 2 months from now

# Date ranges
span = SpanBuilder.date_range(
    start="2026-01-01T00:00:00Z",
    end="2026-12-31T23:59:59Z"
)

Tags with AND/OR Logic

# OR logic (any tag matches)
events = client.get_events_by_tags(
    tags=['AI', 'robotics', 'machine learning'],
    match_all=False
)

# AND logic (all tags must match)
events = client.get_events_by_tags(
    tags=['AI', 'robotics'],
    match_all=True
)

Pagination

# Manual pagination
page1 = client.get_events(limit=10, page=1)
page2 = client.get_events(limit=10, page=2)

# Auto-pagination (gets all results)
all_events = []
page = 1
while True:
    result = client.get_events(limit=100, page=page)
    all_events.extend(result['data'])
    
    paging = result.get('meta', {}).get('paging', {})
    if page >= paging.get('total_pages', 1):
        break
    page += 1

Including Extra Data

# Include speaker information
events = client.get_events(
    span=SpanBuilder.now_plus(30, TimeUnit.DAYS),
    include=['speakers']
)

# Include media attachments
events = client.get_events(include=['media'])

# Include everything
events = client.get_events(
    include=['speakers', 'media', 'enhanced_report']
)

Export to Different Formats

# Export to iCal
client.export_events(
    filename="events.ics",
    format="ics",
    span=SpanBuilder.now_plus(30, TimeUnit.DAYS)
)

# Export to RSS
client.export_events(
    filename="events.rss",
    format="rss",
    limit=50
)

# Get HTML for embedding
html = client.get_events_html(
    span=SpanBuilder.now_plus(7, TimeUnit.DAYS),
    location_type=LocationType.VIRTUAL
)

# CSV export (⚠️ may have connection issues)
try:
    client.export_events("events.csv", format="csv")
except Exception as e:
    print(f"CSV export failed: {e}")

Caching

# Caching is enabled by default with 5-minute TTL
from ieee_events import IEEEEventsClientEnhanced

client = IEEEEventsClientEnhanced(cache_enabled=True)

# Clear cache manually
client.clear_cache()

# Disable caching
client = IEEEEventsClientEnhanced(cache_enabled=False)

Known Limitations

Delta Queries

Delta queries (incremental updates) may cause HTTP 500 errors when combined with certain parameters. This is a server-side limitation.

Workaround:

try:
    delta_events = client.get_events_delta(since="2026-01-01T00:00:00Z")
except Exception as e:
    print(f"Delta query failed: {e}")

Past Events

Queries for past events (negative spans) may sometimes cause server errors depending on the time range and parameters used.

Workaround:

try:
    past_events = client.get_past_events(days=30)
except Exception as e:
    print(f"Past events query failed: {e}")

CSV Export

CSV export may occasionally result in connection reset errors.

Workaround:

try:
    client.export_events("events.csv", format="csv")
except Exception as e:
    # Fallback to JSON and convert to CSV manually
    events = client.get_events(limit=500)
    # Convert to CSV using pandas or csv module

Best Practices

1. Use Caching

Enable caching to reduce API load and improve response times:

from ieee_events import IEEEEventsClientEnhanced

client = IEEEEventsClientEnhanced(cache_enabled=True)

2. Limit Query Scope

Request only the data you need:

# Good: Specific time range
events = client.get_events(span=SpanBuilder.now_plus(7, TimeUnit.DAYS), limit=50)

# Avoid: Very large queries without limits
events = client.get_events(limit=5000)  # May timeout

3. Handle Errors Gracefully

Always wrap API calls in try-except blocks:

try:
    events = client.get_events(span=span)
except requests.exceptions.HTTPError as e:
    print(f"API error: {e}")
except Exception as e:
    print(f"Unexpected error: {e}")

4. Use Type-Safe Enums

Use the provided enums for better IDE support and fewer errors:

from ieee_events import LocationType, TimeUnit, OutputFormat, TagsConnector

client.get_events(
    location_type=LocationType.VIRTUAL,  # ✓ Type-safe
    # location_type="virtual"  # ✗ String (error-prone)
)

5. Optimize with Pagination

For large datasets, use pagination instead of large limit values:

# Good: Paginated approach
for page in range(1, 11):
    events = client.get_events(limit=100, page=page)
    process_events(events['data'])

# Avoid: Single large request
events = client.get_events(limit=1000)  # May be slow

Performance Considerations

Response Times

• Typical query: 200-500ms
• Large queries (500+ results): 1-3 seconds
• With includes (speakers, media): +500ms

Rate Limiting

The API does not have explicit rate limiting, but please:

• Use caching to minimize requests
• Avoid rapid-fire requests
• Implement exponential backoff for retries

Data Freshness

• Event data is updated in real-time
• Cache TTL: 5 minutes (configurable)
• Use delta queries for incremental updates (when working)

Troubleshooting

HTTP 500 Errors

Cause: Server-side error, often due to parameter combinations Solution:

• Remove published and reported parameters
• Reduce time range
• Avoid delta with complex filters

Connection Reset

Cause: Network issues or server timeout Solution:

• Retry with exponential backoff
• Reduce query complexity
• Use smaller time ranges

Empty Results

Cause: No events match the filters Solution:

• Broaden time range
• Remove restrictive filters
• Check if location_type is too specific

Slow Queries

Cause: Large result sets or complex filters Solution:

• Reduce limit parameter
• Use pagination
• Enable caching
• Narrow time range
