v1.0.0 (2023/03/02)

After a lot of work in #39, #53, #55 and #58 (more than 200 commits of refactors and improvements) I can say I'm happy to call this the first release of Chat Analytics!

This is the first entry in the changelog, so I'll just list some changes that were introduced in the PRs:

Pipeline

  • Support for multiple guilds
  • Mostly all the pipeline code has been rewritten with comments and better code overall
  • TESTING: added a lot of tests for the pipeline (+200) with >90% coverage (if excluding aggregation)
  • Now input files that have overlapped messages are merged (duplicate messages are ignored)
  • Now we keep the latest information about authors and channels and guilds, like the name and avatar
  • 4x speedup in base91 decoding
  • I'm sure there is a lot more to put here, but I can't remember

App

  • Changed branding a bit
  • Now it displays the number of files being processed/to be processed
  • It displays the number of guilds when done
  • Moved platform instructions to its own file, and separated platform information from the app, so it can be used in the pipeline
  • Generation errors are now reported to Plausible
  • Now the resulting report HTML file includes the name of the guild/server/group/chat
  • Fix a leak in PII when using Plausible

Report

  • The block request system have been completely replaced: Card now does not require a block key, data must be retrieved with useBlockData, to allow multiple blocks in a single card
  • Improved chart performance:
    • Defer chart creation until the chart is visible
    • Disable chart ticks when not in view
    • Resizing debounced
    • Also removed a lot of boilerplate making a common wrapper, this allowed the optimizations above
  • Created boxplot with histogram chart
  • Now bot authors have an icon alongside their name
  • All charts now have proper tooltips and hover information
  • The timeline tab now shows the number of messages per guild or per group if appropriate
  • Added a link to report issues in ErrorBoundary
  • Most charts have been modified to look prettier (colors, margins, kind of series, etc.)
  • Words have its own stats now: usage over time, who write them the most, which channels they are used the most.
  • Added a few statistics in Message statistics
  • Renamed "combined" to "heatmap" in activity by hour/weekday
  • Fixed the scale of the activity by hour/weekday heatmap, it was inverted
  • Added a card: "Edited messages [by author/in channel]"
  • Added a card: "Time between sending and editing"
  • AnimatedBars now memoize the sort of the items array (used extensively)
  • Now the "Messages sent over time" will default to by month if there is more than 2 years of data (instead of by day)
  • Renamed "non-bot" to "human"
  • Added a card: "Linked by domain hierarchy"
  • Added a card: "Most links sent [by author/in channel]"
  • A lot of other performance and bug fixes

Documentation

  • Added documentation, there was practically none before
  • Cool graphic depicting the pipeline
