Wrium lets you connect ordinary HTML to reactive JavaScript state and event handlers without configuring a bundler or compiler. That makes it worth considering for a small page widget, prototype, demo, or learning project—not as an established substitute for a large framework. Its documented workflow still uses JavaScript modules, so you need a local server for the creator’s example.
What Wrium does
Wrium is a browser-oriented JavaScript library that pairs HTML markup with reactive state. You write the page structure and directives in HTML, create state and functions in JavaScript, and mount the app on a selector. When reactive data changes, Wrium updates the displayed values tied to it.

The project describes a template compiler that reads HTML directly and says no build configuration is required. Its listed reactive primitives are ref, reactive, computed, and watchEffect. The project also lists components, plugins, TypeScript declarations, and automatic dependency tracking with microtask batching. These are project descriptions, not independently evaluated findings. Wrium’s project site advertises version 1.0.0, an MIT license, and a core size of about 10.9 KB minified; the indexed page was not directly verifiable, so check the live package or repository before relying on those details.

How the HTML-first workflow works
The creator’s example installs @wrium/wrium and imports createApp and ref in a <script type="module">. A setup callback returns state and functions, and the app mounts to a selector such as #app. The HTML remains in the page; Wrium connects its bindings to the values and handlers in JavaScript.
#1 Best Overall
For example, a counter can display a value from a ref and call a function when its button is clicked. A todo list extends the same pattern: bind an input with v-model, render items with v-for, attach handlers to actions, and derive the remaining-item count with computed. The creator’s article demonstrates these patterns, rather than establishing a benchmark or production-scale result. Benyamin Khalife’s walkthrough also covers components and custom directives.

What the reactive primitives are for
refholds a reactive value, such as a counter.reactivemakes an object or array reactive.computedderives a value from reactive state, such as a count of unfinished tasks.watchEffectreruns a function when reactive values read by that function change.
This API is useful when the interaction is naturally expressed as state plus a few event handlers. The creator describes it as a way to learn reactivity as well as build small interfaces; that is a positioning claim, not an independent assessment of how quickly a particular developer will learn it.
Rank #2
Does “no build step” mean no setup?
No. The creator’s installation example uses an npm package and browser ES modules. Because that example uses modules, it needs to be served from a local development server rather than opened as a plain file. The stated benefit is avoiding bundler or compiler configuration, not eliminating package installation, a server, or JavaScript tooling altogether.

The creator recommends considering Wrium for small interactive widgets on existing pages, prototypes, demos, and projects that want to avoid a build step. A counter, a compact form interaction, or a simple todo list fits the demonstrated approach.
For a large application that needs routing, server-side rendering, state-management conventions, or a broad ecosystem, the creator says Wrium is probably not the best fit and points readers toward Vue, React, or Svelte. Treat that as the creator’s guidance, not a comparative test: the available sources provide no independent performance figures, adoption statistics, or security or compatibility audit. Choose based on the capabilities and integrations your application needs rather than assuming Wrium is faster or smaller in practice.

The creator identifies several constraints that can affect architecture and compatibility:
Rank #4
- Global registration: directives, components, and hooks are global rather than scoped to each app instance. That may be awkward when isolating multiple apps or composing independently managed parts of a page.
- No slots or dedicated
emit: the creator says a function passed as a prop can serve the event-callback role. This is a different component-composition model to account for in your design. MapandSethandling:reactive()does not specially handle these collections yet, according to the creator.- Browser requirement: Wrium requires
Proxysupport, so it does not support Internet Explorer.
The documentation in the cited sources does not establish independent browser testing or a formal compatibility matrix. If older or unusual browsers matter, verify behavior against your target environment before choosing the library.
Quick Recap
How to decide whether to try Wrium
- Choose a small interaction that can be expressed with a few reactive values, handlers, and HTML bindings.
- Confirm that browser modules and a local server work with your development setup, even if you do not want a bundler.
- Check whether global component and directive registration, the absence of slots, and the stated
Map/Setlimitation fit your design. - Confirm that your supported browsers provide
Proxy. - If you need routing, SSR, extensive integrations, or a large application ecosystem, compare framework options against those requirements; the cited Wrium material does not supply quantitative comparisons.
