test-ts-lib

Example typescript library that runs in both the browser and node.

Biggest gotcha is that the browser requires <script type="module"> for these, not just <script>. this lets the browser use import statements.

notes

• you get maximum compatibility by building both esm (import) and umd (require) modules
• umd is compatible with both commonjs and amd, no need to build those explicitly
• "type": "module" in package.json makes a node project use esm instead of umd. it's a good default these days.
• typescript's compiler cannot bundle its output, but for compatibility and production-readiness we usually want it to. this requires another tool, like tsup. most of them seem to use esbuild
