    Example of an isomorphic mithril application

    Project mention: Show HN: A no-build fullstack SSR TypeScript web framework | news.ycombinator.com | 2025-02-12

    I've been wanting to make a no-build webapp using Mithril.js[1][2], with plain-JS type annotations that don't require build steps (TypeScript's JSDoc syntax [3], but I'm looking forward to the proposed type annotations[4]). With something like this, type-checking would still require running a command when using Node.js, but it's just an optional developer dependency.

    But in the end I've not done that because I figured it's more effort than it's worth, compared to just doing server-side rendering with other backend languages and just using JS where needed (not necessarily "raw" JS, I just mean it as in "not having a full-page component").

    I'm just letting you know that there are definitely some people like me that would like if more JS tooling didn't require a build step or specific runtimes (like Deno or Bun) as a hard dependency.
