    In this code example, I use protobuf.js, a javascript implementation of protobufs. I use reflection to generate the protobuf code at runtime. You can also generate code statically, but it has no impact on performance according to the protobuf.js wiki, however it does load protobuf code faster, but that does not impact the performance at all when sending websocket messages.

    An absurdly small jQuery alternative for modern browsers. (by fabiospampinato)

    Project mention: Cash: A small jQuery alternative for modern browsers | news.ycombinator.com | 2024-11-02

    Back in the days when trying to slim down JS I used https://github.com/filamentgroup/shoestring Main reason was because they had offered a custom build to only add what you really need.

    It looks like cash has that as well, just bit more hidden in the documentation https://github.com/fabiospampinato/cash/blob/master/docs/par... If I'd use it I'd give that a try.

    Somehow I still think going with what the browsers have to offer nowadays is a better option - actually it's really good and jQuery isn't really needed anymore. Especially when even the small jQuery alternative is still 6kB, while Preact, a react like lib, is only half the size.
