Concave polygons not working even after I installed poly-decomp (node server)

I’ve installed poly-decomp with npm install poly-decomp. I then put decomp = require('poly-decomp') above matter = require('matter-js'), when I run my code, it still says poly-decomp.js required. I dug in matter.js code and changed line 6541 to decomp = require('poly-decomp'). It doesn’t give the same message anymore, but my shape is still just convex.

I ran console.log(decomp) after line 6541, and it returned

{ decomp: [Function: polygonDecomp],
quickDecomp: [Function: polygonQuickDecomp],
isSimple: [Function: polygonIsSimple],
removeCollinearPoints: [Function: polygonRemoveCollinearPoints],
makeCCW: [Function: polygonMakeCCW] }

which I think is what it should return. I dug even farther and made sure that line 6763 was being run, and it is. Although, when I console.log(decomp.makeCCW(concave)); on line 6769, it returns undefined. What should I do to make it work? Right now it isn’t giving me the error message, but it isn’t making the shape concave.

Thanks for the info guys, sorry that this is still an issue. While I look into it more, I think this temporary fix should work with the latest version. Make sure you put it somewhere early on, before you use Bodies.fromVertices:

window.decomp = require('poly-decomp');

all solutions above doesn’t work Webpack replaces window.decomp = require('poly-decomp'); by __webpack_provided_window_dot_decomp = __WEBPACK_IMPORTED_MODULE_0_poly_decomp___default.a;

so global window is remains untouched

Using global.decomp = require('poly-decomp') is working for me with Webpack
