WildflowerJS Reactive JS, No BS*

A no-build reactive JavaScript framework, rooted in the web platform.
No build step. No dependencies. No lock-in.

<script src="wildflower.min.js"></script> ...and start building.

Back to Basics

The code you write is 100% web standard code. HTML stays HTML. JavaScript stays JavaScript. CSS stays CSS. No JSX, no templating language, no custom syntax to learn. If you know the web platform, you already know how to use this.

WildflowerJS extends the web platform. It doesn't replace it.

Your Development Simplified

Because you develop with 100% web standards, every tool in your existing chain already understands the code: IDE, browser DevTools, linter, formatter, screen reader, SEO crawler. Nothing to install, no custom file types, no sourcemaps. Save the file, refresh, and your change is live.

Just be a web developer.

Batteries Included: One Mental Model

Router, SSR, stores, computed properties, two-way binding, event modifiers, data pools, and TypeScript types, all built in, all speaking the same language. Learn data-bind once and you know binding everywhere: lists, pools, stores, forms. There's no five-library stack to keep in sync.

One script tag. Everything you need.

<div data-component="counter">
  <span data-bind="count"></span>
  <button data-action="increment">
    +1
  </button>
</div>

<script>
wildflower.component('counter', {
  state: { count: 0 },
  increment() { this.count++ }
})
</script>

How It Works

data-bind connects state to the DOM.

data-action connects events to methods.

this.count++ triggers a precise DOM update.

Mutate state. The DOM updates.

Two Reactivity Modes

data-list for automatic reactivity: mutate state, DOM updates. data-pool for explicit control: plain objects, zero proxy overhead, you say what changed.

Same template syntax. Different performance profile. From interactive forms to per-frame particle systems. You choose the right tradeoff for the job.

Try it. Right-click, inspect this demo. Every dot is a real DOM element.

* Build Step

Zero Toolchain

Modern frameworks ask you to install a compiler, a bundler, a package manager, hundreds of fragile transitive dependencies, and a framework-specific file format, before you write a single line of your application.

WildflowerJS was built starting from a single principle: no build step, no tooling. Ever.

WildflowerJS asks you to add a script tag.

There's no CLI scaffolding step, no config files, no .vue/.jsx/.svelte source format. You don't debug through sourcemaps or wait on a build pipeline. Your project has zero dependencies.

Performance isn't a tradeoff. Build steps optimize bundle delivery, not the runtime work that follows it. WildflowerJS writes directly to the DOM, with no virtual DOM or reconciliation pass between state change and update, so it doesn't need a build step to be fast.

The framework is full-featured without the toolchain: router, SSR, stores, computed properties, transitions, pools. You don't need a toolchain to use any of it.

my-app/
  index.html
  app.js
  style.css
  wildflower.min.js

That's the entire project. No package.json.
No node_modules. No config files. Ship it.

Zero Install. Zero Attack Surface.

Every dependency you install is trust extended to a maintainer you've never met, running scripts on your dev machine and in your CI. A typical React + Vite + UI‑lib setup pulls in 300+ transitive packages before you write a feature.

Each one is a potential intrusion vector. NPM worms, OAuth chains compromising deploy platforms, postinstall hijacking: the supply chain is now where production code gets compromised, not the deploy. And signing isn't a backstop: Mini Shai‑Hulud (May 2026) compromised 170+ packages whose malicious versions carried valid SLSA Build Level 3 provenance, because the attestation came from build infrastructure the worm had already taken over.

WildflowerJS users don't have this attack surface, by construction. There is no npm install, no postinstall script, no transitive package graph. The framework is one file you copy or pin by hash.

As of v1.1, the same holds for building the framework itself. WildflowerJS bundles with a vendored rollup and terser pipeline pulled as three SHA‑512‑pinned tarballs: no npm install, no transitive packages, no postinstall scripts in the build path. The entire toolchain is three files you verify by hash.

Zero dependencies is the absence of a problem the rest of the industry has not properly addressed.

A typical React/Vue project:

  npm install
  ├── hundreds of packages
  ├── from hundreds of maintainers
  ├── postinstall scripts run on install
  └── tens to hundreds of MB of transitive code

WildflowerJS:

  <script src="wildflower.min.js"></script>
  └── 1 file.
      No transitive dependencies.

Zero Lock-in

WildflowerJS works with the DOM, not instead of it. There's no virtual DOM intercepting your code and no compiler rewriting your markup. The render cycle is yours.

That means Leaflet, DataTables, Chart.js, D3, Three.js, any library that touches the DOM, just works. No wrapper packages or framework-specific escape hatches required. Drop in a script tag and use it.

Because your code is standard HTML and JavaScript, you're never locked in. Your skills transfer and your code is more portable. If you outgrow the framework, your knowledge doesn't expire.

This also means your "ecosystem" is all of the world of vanilla JS. Without compromises or hacks.

<!-- Use any library directly -->
<div data-component="map-view">
  <div id="map" style="height: 400px"></div>
</div>
wildflower.component('map-view', {
  state: { lat: 51.505, lng: -0.09 },
  init() {
    // Leaflet works as-is. No wrappers.
    this._map = L.map('map')
      .setView([this.lat, this.lng], 13);
    L.tileLayer('https://{s}.tile.osm.org'
      + '/{z}/{x}/{y}.png').addTo(this._map);
  }
})

Precise Reactivity

When you write this.count++, WildflowerJS updates the single DOM node bound to count. Nothing else is touched. There's no tree diffing or reconciliation pass to figure that out.

This isn't a tradeoff. You get fine-grained updates and a simple mental model. Change a property, the bound element updates. That's the entire reactivity model.

Other frameworks ask you to learn signals, accessors, memos, effects, and subscription lifecycles to achieve what WildflowerJS does with a property assignment.

wildflower.component('dashboard', {
  state: {
    users: 1420,
    status: 'healthy'
  },
  computed: {
    summary() {
      return this.users + ' users, ' + this.status;
    }
  },
  refresh() {
    this.users = 1421;
    // Only the elements bound to 'users'
    // and 'summary' update. Everything
    // else on the page is untouched.
  }
})

One Reactivity Model. Everywhere.

Components, Stores, and Plugins all share the same reactive foundation. State, computed properties, and methods work identically no matter where they live. Learn it once, it works the same way in a UI component, a global store, or a framework plugin.

Other frameworks make you learn a different system for each layer. React components use hooks, but stores need Redux or Zustand, which are completely different APIs. Vue components use reactive data, but Pinia stores have their own patterns. Every layer is a new mental model.

In WildflowerJS, there's one model. A store is a component without a template. A plugin is an entity that extends the framework itself, adding directives, lifecycle hooks, and services. The same this.count++ triggers the same reactivity everywhere.

This unlocks patterns other frameworks can't express. A store can run headless physics simulations with tick(), feeding data into a component that renders it through a pool, all using the same reactive primitives, no glue code required.

// Component: reactive UI
wildflower.component('cart', {
  state: { items: [] },
  computed: {
    total() { return this.items.length; }
  }
})

// Store: global shared state
wildflower.store('user', {
  state: { name: '', role: 'guest' },
  computed: {
    isAdmin() { return this.role === 'admin'; }
  }
})

// Plugin: extends the framework
wildflower.plugin({
  name: 'notifications',
  state: { items: [], unreadCount: 0 },
  computed: {
    hasUnread() { return this.unreadCount > 0; }
  },
  add(msg) { this.items.push(msg); this.unreadCount++; }
})
// Access globally: wildflower.$notifications.add(...)

// Same state. Same computed. Same methods.

Data Pools

Every framework wraps collection items in reactive proxies, whether the item needs it or not. WildflowerJS gives you a choice: data-list for push reactivity (automatic), data-pool for pull reactivity (explicit control, zero proxy overhead).

Pools render plain objects with the same template syntax as lists. Mutate the object, call markDirty(), and only that item updates. Full CRUD, selection, bulk operations, all faster than the push-reactive path.

And because pools use pull-based rendering, they scale to simulations, games, particle systems, and data visualizations at native frame rate. Use cases that would choke a virtual DOM. No other framework has anything like this.

<div data-component="user-table">
  <tbody data-pool="users" data-key="id">
    <template>
      <tr>
        <td data-bind="name"></td>
        <td data-bind="status"
            data-bind-class="status === 'active'
              ? 'badge success'
              : 'badge inactive'"></td>
      </tr>
    </template>
  </tbody>
</div>
wildflower.component('user-table', {
  pools: { users: {} },

  init() {
    // Populate: plain objects, no proxies
    data.forEach(u => this.pools.users.add(u));
  },

  // Optional: add tick() and the same pool
  // renders every frame. Same template, same
  // data, different rendering frequency.
  // That's the only difference between a
  // display table and a particle system.
})

Built for AI-Assisted Development

Because WildflowerJS is standard HTML and JavaScript, AI code assistants already know how to write it. There's no custom syntax to hallucinate or compiler quirks to work around. The code an AI generates runs exactly as written, with no build step between generation and execution.

We go further. WildflowerJS ships an AI-optimized reference page with patterns, anti-patterns, and examples designed for code generation context windows. Our llms.txt file follows the llms.txt convention for machine-readable documentation.

And for structured app generation, our Universal App Manifest lets you describe an entire application as a JSON schema (components, state, computed properties, methods, templates) and have an AI generate the working code from the manifest, mediated through framework-specific idiom files.

You: "Build me a todo app with
WildflowerJS"

AI reads llms.txt or ai-assistant.html

Open in your browser. It works, and you can read and understand the code.

Why WildflowerJS?

A framework that trusts the browser instead of fighting it. No build step, no transitive dependencies, no lock-in.

The Problem with Modern Frameworks

Today's popular JavaScript frameworks have made web development more complex than it needs to be:

Build Step Required

JSX, TypeScript, Vue SFCs, Svelte components: none of these work in a browser without compilation. You can't just open an HTML file and start coding.

Framework-Specific Syntax

Every framework invents its own way of doing things. Learning React doesn't help you learn Vue. Skills don't transfer.

Library Wrapper Tax

Want to use a datepicker? You need react-datepicker. A chart library? Install vue-chartjs. Every third-party library requires a framework-specific wrapper.

Supply Chain Surface

A modern React or Vue project installs 300+ transitive packages from many maintainers, each one a potential intrusion vector. Your toolchain is now an attack surface.

The WildflowerJS Approach

WildflowerJS takes a different path. Instead of abstracting away the browser, we work with it.

Standard HTML

Your HTML is real HTML. Open it in any editor or browser. No template language, no compilation step. Just HTML with data attributes.

<div data-component="counter">
    <span data-bind="count">0</span>
    <button data-action="increment">+</button>
</div>

Standard JavaScript

Components are plain JavaScript objects, with no class decorators or preprocessor required. Any JavaScript developer can read this:

wildflower.component('counter', {
    state: { count: 0 },
    increment() { this.count++; }
});

Native Library Integration

Use any JavaScript library directly without wrappers. Chart.js, Flatpickr, DataTables, or anything that works with the DOM works with WildflowerJS.

No Build Step

Add a script tag and start coding. No webpack or vite, no configuration files. Works for prototypes and production alike.

<script src="wildflower.min.js"></script>
<!-- That's it. Start building. -->

AI-Friendly by Construction

LLMs like Claude, Gemini, and GPT are excellent at HTML, CSS, and JavaScript because those make up most of their training corpus. Framework-specific syntax is a thinner slice. WildflowerJS code is what AI generates cleanly without translation, and what humans can debug without sourcemaps.

TypeScript Where It Counts

Type-safe state, computed properties, and stores ship with the framework. Your existing TS skills transfer directly. The runtime types validator catches binding-shape drift in dev. Template-level type-checking for data-bind expressions is on the roadmap.

Zero Install. Zero Attack Surface.

Every dependency you install is trust extended to a maintainer you've never met, running scripts on your dev machine and in your CI. A typical React + Vite + UI-lib setup pulls in 300+ transitive packages before you write a feature.

Each one is a potential intrusion vector. NPM worms, OAuth chains compromising deploy platforms, postinstall hijacking: the supply chain is now where production code gets compromised, not the deploy.

WildflowerJS users don't have this attack surface, by construction. There is no npm install, no postinstall script, no transitive package graph. The framework is one file you copy or pin by hash.

Zero dependencies is the absence of a problem the rest of the industry has not properly addressed.

Performance Without Compromise

By working with the browser instead of abstracting it away, WildflowerJS achieves excellent performance across the board, from bulk list operations to fine-grained reactive updates.

Direct DOM Updates

No virtual DOM diffing overhead. State changes go straight to the elements that need updating. The browser handles the rest with decades of optimization.

Small Footprint

The full framework ships as a single bundle that includes stores, routing, and SSR. No additional state management library required.

Where WildflowerJS Shines

WildflowerJS is built for reactive web development at any scale. From prototypes to production, solo builders to large teams, the framework's design and performance hold up. Some scenarios it's particularly well-suited to:

Project Types

  • Customer-facing SaaS, internal tools, dashboards
  • Embedded widgets and interactive components
  • Documentation sites with live examples
  • Anywhere bundle size and load time matter

Team Priorities

  • Shipping product over configuring tooling
  • Supply-chain risk treated as a real concern
  • AI-assisted code generation that runs as written
  • Skills that transfer when frameworks change

The Philosophy

Trust the Platform

Browsers have billions of hours of optimization behind them. The DOM isn't slow; inefficient abstractions are. We work with browser APIs, not against them.

Separation of Concerns

HTML describes structure. CSS describes presentation. JavaScript describes behavior. They work together but stay separate. This isn't old-fashioned; it's sustainable.

Progressive Enhancement

Your HTML works without JavaScript. The framework enhances it. This isn't just about accessibility; it's about resilience.

No Magic

When you read WildflowerJS code, you understand what it does. No transpilation obscures the intent, no build step transforms your logic. What you write is what runs.

How Updates Work

When state changes in WildflowerJS, updates flow directly to the DOM:

State Changes this.count++
→
Context Notified Binding knows its element
→
DOM Updated Element.textContent = 1

There's no intermediate representation, no tree diffing, no reconciliation phase. The framework knows exactly which element displays count, and updates it directly.

Element-Level Precision

Each binding tracks its own dependencies. When count changes:

  • Only elements bound to count update
  • Other bindings don't re-evaluate
  • No parent components re-render
  • No children are touched

This granularity comes from the context system. Each data-bind, data-show, or data-list has its own context that knows exactly what it depends on and what DOM element it controls.

State Without Ceremony

State in WildflowerJS is just a JavaScript object. No special wrappers, no access patterns to memorize:

// Define state
state: {
    count: 0,
    user: { name: 'Alice', score: 100 }
}

// Update state by assigning
this.count++
this.user.name = 'Bob'
this.user = { name: 'Charlie', score: 200 }

// All of these trigger reactive updates automatically

Nested properties, array mutations, and complete replacements all work the same way. The reactivity system handles it.

Ready to Try It?

The quickest way to start is with a single script tag:

<!DOCTYPE html>
<html>
<head>
    <script src="https://cdn.jsdelivr.net/npm/wildflowerjs@1/dist/wildflower.min.js"></script>
</head>
<body>
    <div data-component="hello">
        <p>Hello, <span data-bind="name">World</span>!</p>
        <input data-model="name" placeholder="Enter your name">
    </div>

    <script>
        wildflower.component('hello', {
            state: { name: 'World' }
        });
    </script>
</body>
</html>

That's a complete, reactive application. No build step or configuration; just HTML and JavaScript working together.
