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
     ↓
Generates standard HTML + JS
     ↓
<div data-component="todo-app">

  <ul data-list="items">
    <template>
      <li data-bind="text"></li>
    </template>
  </ul>
</div>

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

Coming From...

Already know React, Vue, Solid, Svelte, or Alpine? This guide maps concepts you already understand to WildflowerJS equivalents.

The big picture: WildflowerJS uses standard HTML data-* attributes instead of custom template syntax. State is mutated directly (no immutable patterns). There's no build step, no virtual DOM, no JSX, and no framework-specific file formats. HTML stays HTML. JavaScript stays JavaScript.

Quick Concept Map

No matter which framework you're coming from, here's how the core ideas translate:

Concept React Vue Svelte WildflowerJS
Component function + JSX .vue SFC .svelte file data-component + JS object
State useState() ref() / reactive() $state() state: {}
Computed useMemo() computed() $derived() computed: {}
Text output {count} {{ count }} {count} data-bind="count"
Event onClick={fn} @click="fn" onclick={fn} data-action="fn"
Conditional {cond && ...} v-if / v-show {#if} data-show / data-render
List .map() v-for {#each} data-list
Two-way bind Manual onChange v-model bind:value data-model
Global state Context / Redux Pinia Svelte stores wildflower.store()
Lifecycle useEffect() onMounted() onMount() init() / destroy()
Build step Required Recommended Required None

Coming from React

The biggest shifts: no JSX, no hooks, no immutable state patterns.

Component Definition

React
function Counter() {
    const [count, setCount] = useState(0);
    return (
        <button onClick={() => setCount(c => c + 1)}>
            Count: {count}
        </button>
    );
}
WildflowerJS
<div data-component="counter">
    <button data-action="increment">
        Count: <span data-bind="count">0</span>
    </button>
</div>
wildflower.component('counter', {
    state: { count: 0 },
    increment() { this.count++; }
});

State Updates

React requires immutable updates. WildflowerJS supports both patterns, but direct mutation is simpler and enables targeted DOM updates:

React
// Must create new references
setItems([...items, newItem]);
setItems(items.filter(i => i.id !== id));
setUser({ ...user, name: 'Alice' });
WildflowerJS
// Direct mutation: simpler and faster
this.items.push(newItem);
this.items.splice(index, 1);
this.user.name = 'Alice';

// Immutable patterns also work if you prefer
this.items = [...this.items, newItem];

Hooks → Component Properties

React
const [count, setCount] = useState(0);
const doubled = useMemo(() => count * 2, [count]);
useEffect(() => {
    console.log('mounted');
    return () => console.log('cleanup');
}, []);
WildflowerJS
wildflower.component('example', {
    state: { count: 0 },
    computed: {
        doubled() { return this.count * 2; }
    },
    init() { console.log('mounted'); },
    destroy() { console.log('cleanup'); }
});

Context / Redux → Stores

React (Context)
const CartContext = createContext();

function CartProvider({ children }) {
    const [items, setItems] = useState([]);
    return (
        <CartContext.Provider value={{ items, setItems }}>
            {children}
        </CartContext.Provider>
    );
}

// In child:
const { items } = useContext(CartContext);
WildflowerJS
wildflower.store('cart', {
    state: { items: [] },
    addItem(item) { this.items.push(item); }
});

// In any component:
wildflower.component('checkout', {
    subscribe: { cart: ['items'] },
    computed: {
        total() {
            return this.stores.cart.items
                .reduce((s, i) => s + i.price, 0);
        }
    }
});
Differences from React: No JSX. No build step. No rules of hooks. No dependency arrays. No stale closures. No re-render optimization (memo, useCallback). State is a plain object; methods are plain functions.

Coming from Vue

Vue and WildflowerJS share a lot of philosophy: reactive state, direct mutation, declarative templates. The main difference is syntax: Vue uses custom directives (v-if, @click); WildflowerJS uses standard data-* attributes.

Directive Mapping

VueWildflowerJSNotes
{{ count }}data-bind="count"Text interpolation
v-html="content"data-bind-html="content"Raw HTML
@click="method"data-action="method"Click is default event
@input="method"data-action="input:method"Prefix with event name
v-model="prop"data-model="prop"Two-way binding
v-if="cond"data-render="cond"DOM insertion/removal
v-show="cond"data-show="cond"CSS display toggle
v-for="item in items"data-list="items"Uses <template> child
:key="item.id"data-key="id"On the list container
:class="expr"data-bind-class="expr"Dynamic classes
:style="expr"data-bind-style="expr"Dynamic styles

Composition API → Component Definition

Vue 3 (script setup)
import { ref, computed } from 'vue'

const count = ref(0)
const doubled = computed(() => count.value * 2)
function increment() { count.value++ }
WildflowerJS
wildflower.component('counter', {
    state: { count: 0 },
    computed: {
        doubled() { return this.count * 2; }
    },
    increment() { this.count++; }
});

Pinia → Stores

Vue (Pinia)
export const useCartStore = defineStore('cart', {
    state: () => ({ items: [] }),
    getters: {
        total: (state) =>
            state.items.reduce((s, i) => s + i.price, 0)
    },
    actions: {
        addItem(item) { this.items.push(item); }
    }
});
WildflowerJS
wildflower.store('cart', {
    state: { items: [] },
    computed: {
        total() {
            return this.items.reduce((s, i) => s + i.price, 0);
        }
    },
    addItem(item) { this.items.push(item); }
});
Differences from Vue: No .value unwrapping. No build step needed. No custom directives: data-* attributes are valid HTML. Stores and plugins have the same structure as components (state, computed, methods), with no separate getters/actions blocks.

Deep Dive: Migrating from Vue →. Directive mapping, side-by-side Todo app, pattern-by-pattern migration, gotchas, and checklist.

Coming from Solid

Solid and WildflowerJS both avoid the virtual DOM and use fine-grained reactivity. The key difference: Solid requires signal getters (count()); WildflowerJS resolves properties automatically.

Signals → State

Solid
// Signals: for primitive values
const [count, setCount] = createSignal(0);
// Read: count()  Write: setCount(count() + 1)

// Stores: for nested objects/arrays
const [items, setItems] = createStore([]);
// Mutate: setItems(produce(s => s.push(item)))
// Or: setItems(items.length, newItem)
WildflowerJS
state: { count: 0, items: [] }

// Read: this.count  (property access)
// Write: this.count++
// Write: this.items.push(item)

createMemo → Computed

Solid
const doubled = createMemo(() => count() * 2);
// Access: doubled()
WildflowerJS
computed: {
    doubled() { return this.count * 2; }
}
// Access: this.doubled (or data-bind="doubled")

JSX Control Flow → Data Attributes

Solid
<Show when={isVisible()}>
    <div>Visible</div>
</Show>
<For each={items()}>
    {item => <li>{item.name}</li>}
</For>
WildflowerJS
<div data-show="isVisible">Visible</div>

<ul data-list="items" data-key="id">
    <template>
        <li data-bind="name"></li>
    </template>
</ul>
Differences from Solid: No getter functions, just this.count instead of count(). No produce() for mutations. No JSX or build step. Same fine-grained reactivity, different authoring model.

Deep Dive: Migrating from Solid →. Signal-to-state mapping, side-by-side Todo app, pattern-by-pattern migration, gotchas, and checklist.

Coming from Svelte

Svelte and WildflowerJS both favor direct mutation and minimal boilerplate. The difference: Svelte compiles .svelte files; WildflowerJS works directly in the browser with plain HTML.

Reactivity

Svelte 5
let count = $state(0);
let doubled = $derived(count * 2);

function increment() { count++; }
WildflowerJS
wildflower.component('counter', {
    state: { count: 0 },
    computed: {
        doubled() { return this.count * 2; }
    },
    increment() { this.count++; }
});

Template Syntax

Svelte
<button onclick={increment}>{count}</button>
{#if isVisible}<div>Shown</div>{/if}
{#each items as item (item.id)}
    <li>{item.name}</li>
{/each}
<input bind:value={name} />
WildflowerJS
<button data-action="increment">
    <span data-bind="count"></span>
</button>
<div data-render="isVisible">Shown</div>
<ul data-list="items" data-key="id">
    <template><li data-bind="name"></li></template>
</ul>
<input data-model="name" />
Differences from Svelte: No compiler. No .svelte file format. No $state() / $derived() runes. Standard HTML works in any editor, any server, any CDN, with no build pipeline required.

Deep Dive: Migrating from Svelte →. Runes-to-state mapping, side-by-side Todo app, pattern-by-pattern migration, gotchas, and checklist.

Coming from Alpine.js

Alpine is the closest relative to WildflowerJS. Both are attribute-based, no-build-step frameworks. WildflowerJS adds proper component lifecycle, stores with subscriptions, computed caching, and keyed list reconciliation.

Attribute Mapping

AlpineWildflowerJSNotes
x-data="{ count: 0 }"data-component="name"State is defined in JS, not inline
x-text="count"data-bind="count"
x-html="content"data-bind-html="content"
@click="count++"data-action="increment"Logic lives in JS methods, not inline
x-model="name"data-model="name"
x-show="isOpen"data-show="isOpen"Nearly identical
x-if="isOpen"data-render="isOpen"DOM insertion/removal
x-for="item in items"data-list="items"Uses <template> child
:class="expr"data-bind-class="expr"
Alpine.store('name', {})wildflower.store('name', {})Very similar API

Inline Logic → Defined Methods

Alpine
<div x-data="{ count: 0, get doubled() {
    return this.count * 2 } }">
    <button @click="count++">
        <span x-text="doubled"></span>
    </button>
</div>
WildflowerJS
<div data-component="counter">
    <button data-action="increment">
        <span data-bind="doubled"></span>
    </button>
</div>
wildflower.component('counter', {
    state: { count: 0 },
    computed: {
        doubled() { return this.count * 2; }
    },
    increment() { this.count++; }
});
Differences from Alpine: Cached computed properties (Alpine getters re-run every access). Keyed list reconciliation. Full component lifecycle (init, destroy, watch). Store subscriptions with automatic cleanup. Separation of logic from markup, with no inline JavaScript in attributes.

Deep Dive: Migrating from Alpine.js →. Attribute mapping, scaling beyond Alpine, side-by-side Todo app, gotchas, and checklist.

Universal Patterns

A few WildflowerJS patterns that don't have direct equivalents in other frameworks:

Cross-Entity Access

Access any store or component directly in HTML with the $ prefix:

<!-- Read from a store in any component's template -->
<span data-bind="$user.name"></span>
<div data-show="$auth.isLoggedIn">Welcome!</div>
<div data-list="$cart.items" data-key="id">
    <template><span data-bind="name"></span></template>
</div>

Store Subscriptions

Declarative store wiring with automatic cleanup on component destroy:

wildflower.component('dashboard', {
    subscribe: {
        user: ['profile', 'preferences'],
        cart: ['items']
    },

    // Fires when any subscribed path changes
    onStoreUpdate(storeName, path, newValue, oldValue) {
        if (storeName === 'cart') this.refreshTotals();
    }
});

List Action Context

Action handlers inside lists receive full context, including the item, its index, and parent list info:

deleteCard(event, element, details) {
    const card = details.item;           // Current list item
    const index = details.index;         // Position in array
    const column = details.parent.item;  // Parent list item (nested lists)
    this.items.splice(index, 1);
}

Built-in Store Persistence

One-line localStorage persistence, no middleware or plugins needed:

wildflower.store('settings', {
    storageKey: 'app-settings',  // localStorage key
    autoSave: true,              // Persists on every state change
    state: { theme: 'light', fontSize: 14 }
});
