Looking for a javascript library with good wrapping support
It is likely that paper.js provides the functionality needed. I will probably investigate it at some point since it appears to be the more popular library Compare paper.js & bezier.js.

The Continuity of Splines – Video Essay by Freya Holmér
Ooh, the Chebyshev basis is neat. I hadn't seen exactly that before. It reminds me a lot of the "shape control" technique[1] which is also similar to a basis function approach but has a bit of linear solving. Essentially, you get one point (usually at t = 0.5), and also the direction but not magnitudes of the tangents at the endpoints (G1, not C1). This is one of the better-performing existing techniques for offset curve, though does have stability problems (in particular, nasty behavior for a symmetric "S" curve).
Regarding collaboration with Freya, if she is open to it, please get in touch. I do have some ideas.

Writing HTML sucks and No-code doesn't help
> <p>Oh yeah, you reminded me of the template fatigue that was paper.js and it trying to reinvent scripting on the client side with <script type="text/paperscript"> templates that could use templates that could use templates... and so on. [0] I was wondering why people would go to such great lengths just to avoid having to script in the browser.<p>The way I saw it at the time was that I've rediscovered the same mistakes that PHP did back in the days. All the recurs(iv)ed templating problems, all the OOP fatigue that never worked out (magento and zend, anyone?), and all the inheritance based "reinventions" of existing web technologies like OOCSS [1].<p>I mean, at some point every engineer should be wise enough to give up on trying to predict the future. Especially in projects they cannot predict what features are going to be implemented, so I'd naturally assume that modularity and compositional or entity/component aspects will win in later revisions or refactor decisions. But I was wrong with that assumption, I guess :S<p>I also can kinda understand the general bias towards closure among functional folks. I guess that lots of people at the time (or nowadays) had high hopes for it allowing to go more "functional" in its approach, allowing compositional patterns to be useful on the web. But, honestly, JS itself is so flexible and can be used in all kinds of architectural patterns that I think closure's purpose is kind of void by its own concept.<p>When comparing closure with, say, typescript (which I also don't agree with, because "string" and "String" and "any" are pointless from any language design perspective): Typescript at least has the benefit of typed API docs and good IDE integrations (due to LSP) that can be used in large teams to reduce the overhead of getting started with working on foreignly-owned code - whereas closure doesn't have any unique selling point in my opinion. I mean, even scala.js has a unique selling point when being judged like that.<p>[0] <a href="https://github.com/paperjs/paper.js" rel="nofollow">https://github.com/paperjs/paper.js</a><p>[1] <a href="http://oocss.org/" rel="nofollow">http://oocss.org/</a>
