That is totally true, most of my libraries (except a couple of them[1][2]) are small enough and incremental enough that are normally not worth it to even try to sell them. But I can see if I went very deep into some specific niche how that'd make sense. [1] https://serverjs.io/ https://serverjs.io/ => a generic well configured Node.js server, there's a chance of selling either the lib itself or plugins. [2] https://react-test.dev/ https://react-test.dev/ => a WIP (frozen right now) project, it works great and integrates nicely with React libraries.
