Various possible approaches:

Draw lines, apply polygon offset to faces (simplest but mediocre quality/performance)
Fragment shader based approaches (relies on including barycentric coordinates or similar in vertex data, requires support for GLSL standard derivatives)
Post processing of depth map data (requires support for multipass rendering)

Perhaps use lambertian / fwidth(lambertian) for toon shading, as suggested by https://twitter.com/rickyreusser/status/1023852556060057600 (would require standard derivative support in the webgl package)
