Module not found: Can't resolve 'poly-decomp'

I am seeing this message in the debug output when using matter-js:

./node_modules/.pnpm/matter-js@0.16.1/node_modules/matter-js/build/matter.js Module not found: Can’t resolve ‘poly-decomp’ in ‘C:\dev\webpranks\node_modules.pnpm\matter-js@0.16.1\node_modules\matter-js\build’

This is the minimal code to reproduce:

import { Engine, Render, Bodies, World } from "matter-js";
const engine = Engine.create();

To be clear for anyone still seeing this issue you can avoid the warning for the moment by just installing the module via npm install poly-decomp --save (even though it’s technically optional).

The problem seems to be external - build tools don’t appear to handle conditional require calls as expected, which I’m not sure there’s a fix for (unless anybody has any ideas).

So unfortunately there may need to be a breaking change coming (which I’ve been trying to avoid): removing this require all together and asking users to pass the decomp module as an argument (or set the global). I’m sure that will create just as much confusion as this error though.

As of release 0.17.0 the approach is now to use the new function Common.setDecomp, which you can see in use on the concave example.

The window.decomp global is also still supported, but it is still advised to specifically use Common.setDecomp where possible.

There is no longer any require usage meaning bundlers should work fine, so considering the issue now resolved but feel free to comment still if needed. Thanks again for reporting.
