TL;DR: dagger.js is a buildless, runtime-only micro-framework that plays nicely with native Web Components. It uses HTML-first directives (e.g. +click, +load) so you can ship a page by dropping a single <script> from a CDN—no bundlers, no compile step.

Why I built it Modern stacks are powerful but often heavy: bundlers, compile steps, framework DSLs, local CLIs. For internal tools, small apps, and edge/serverless deployments, I wanted something you can view-source, paste into a page, and ship.

What it is:

Runtime-only: no build or VDOM compile; hydrate behaviors directly on HTML. HTML directives: e.g. +click, lifecycle +load / +loaded / +unload / +unloaded. Zero APIs: dagger.js works in pure declarative mode, modules and directives provide everything you need to build your application. Web-Components-first: works alongside Custom Elements; keep concerns local. Distributed modules: load small, focused script modules via CDN. Progressive enhancement: the page renders without a build step.

Use cases:

Admin panels & dashboards that don’t warrant a full toolchain Embed widgets, docs-sites with interactive bits Edge/serverless apps where cold start and simplicity matter

I’d love feedback on edge-cases, and where it breaks. Happy to answer tough questions here.

What is the risk here?

Are you worried that in a year it will be missing a feature you want?

It's client side javascript, aside from DOM based XSS (which if reported, you can probably fix yourself), there isn't much to worry about from the security perspective. The web doesn't normally deprecate things so it's probably going to work in a year too.

This is a tiny project which already requires that you know JavaScript, so you can't even claim that you can't maintain it because you don't know the implementation language. It doesn't depend on some build step (which often is the thing that breaks after a year).
