Typography Benchmarks

To isolate typography tests, run the following:

npx vitest bench test/bench/typography.bench.js --reporter=verbose

Implementation notes:

  • All pre-existing benchmarks included the full p5 instance setup which adds ~50ms to each test. The textToPoints() single word, isolated benchmark test is included as a potential way to isolate performance testing away from setup overhead.
  • The with render test draws the points, others just run textToPoints().

Open tasks

  1. Add benchmarks for the following functions:

    • textToContours()
    • textToPaths()
    • textToPoints()
    • textToContours()
    • textToPaths()
    • textToModel()

  2. Consider how we might parameterize code re-use accross tests for the 3 renderers. See initial notes in typography.bench.js. Without this, tests may begin to drift over time without careful code reviews.

  3. Create a custom vitest reporter to help automate updating this document.
