### External dependencies
The dyna3 program depends on some externally-maintained JavaScript libraries/modules. The package uses npm to track these external dependencies. A module externals.js is automatically generated from the package_lock.json file created by npm to load the necessary modules at runtime.
The dyna3 program depends on some externally-maintained JavaScript libraries/modules. The package uses npm to track these external dependencies. A module externals.js is automatically generated from the package.json and package_lock.json files created by npm to load the necessary modules at runtime.
The generation is performed by pkglock_to_externals.litcoffee, which also records the main importable file within the library, as there does not seem to be a systematic way to generate that filename from the module name.
Specific packages/implementation approaches for components of dyna3 include the following items. All packages are obtained from npm unless otherwise noted.
- for conversion of markdown to HTML: pandoc
- For a test harness for the package: QUnit
- For a test harness for the package: Ava
- When a point is reached at which there is a need to test in-browser behavior, ava can call Puppeteer as per https://github.com/avajs/ava/blob/master/docs/recipes/puppeteer.md
- For WebGL rendering of the 3D view of the geometry: three
