Performance

Firestore Optimization

• Only load unread/recent notifications - Nov 23 - 3.0.8
• Only load ten most recent comments by default with button to view all - Nov 23 - 3.0.8
• Reduce Firestore costs by combining line and station documents into one (or a few) map document(s). - Nov 23 - 3.1.0
  • no longer store individual documents for each station/line/interchange
  • combine them into one document instead
  • if that document is larger than Firestore supports, split it into partitions
  • remove station density info from large maps
  • write script to migrate existing systems
• Implement local cache for high-intensity queries - March 23 - 3.8.0
  • related and nearby maps sections with first check local cache and the count of matching documents on the server
  • clear local cache after one day to ensure it stays pretty fresh

Map Responsiveness - Nov 23 to Jan 24 - 3.2.0, 3.5.1

• Dynamically precalulcate where transfers between lines are and what lines each station is on - 3.2.0
  • Use this memoized object to dramatically reduce calculations made in the render loop
  • Also use it to significantly improve performance of interline segment calculation
  • This improved edit performance of very large maps by over 90%! And load time of maps by 60%!
• Hide station pins until you reach a map level-specific zoom value, then render the pins - 3.2.0
  • Having so many elements in the DOM on initial load impacted render time of the rest of the app
• Load stations as a layer instead of pins to dramatically improve snappiness on maps with thousands of stations/waypoints - 3.5.1

3.0 - Dec 22 to Feb 23

See all the juicy goodness in the 3.0 release here.

Map Improvements

layers - Jan 24 - 3.6

• satellite layer
• topographic layer
• railways layer

interline segments - Aug 22 - 2.1

• finally parallel lines appear along side of one another
• calculating the offsets for these was a brain teaser. required some trig!

optimization - Aug to Oct 22 - 2.1

• refactor and update Map to a functional component
• remove layer setTimeout stuff
• render as few layers as possible (group lines together, vehicles together, etc)
• still waiting on a resolution to this mapboxgl github issue to fully finish this for segments

vehicles - Oct 22 - 2.2

• animated circles that slow down and stop and stations before accelerating away
• remain as close to previous position as possible when line is updated

Line Features

line modes - Oct 22 - 2.2

• choose between five modes from bus to high speed rail, defaulting to metro/subway
• impacts travel time and vehicle speed, pause, and acceleration

Waypoints - Oct 22 - 2.2

• points where a line travels through but does not stop
• solves the issue of straight lines between stations
• do not show waypoint markers in viewonly
