adi518 / react-popper-tooltip-treeshake-reproduction

This repository was setup to reproduce a tree-shaking issue with react-popper-tooltip. See: mohsinulhaq/react-popper-tooltip#97

How To Reproduce

1. Hit yarn to bootstrap the workspace.
2. Change directory to ui-components and hit yarn build:rollup.
3. Change directory to my-app, hit yarn build and then yarn build:analyze.
4. In the analyzer window, select build/static/js/main.*.chunk.js file and you should see just the Button component code.
5. Go to ui-components/src/index.ts and uncomment PopperTooltip. Repeat steps 1-4, you should now see react-popper-tooltip code despite being unused by the application. You can also run yarn check-treeshake under ui-components to check whether tree-shaking was successful. However, with react-popper-tooltip it seems to fail fatally, so no real output. I suggest inspecting the output of ui-components/dist/esm/index.js.
