Computed Properties
Derive reactive values from state with automatic dependency tracking and efficient caching.
Basic Computed Properties
Define computed properties in your component definition. They automatically track dependencies and update when dependent state changes:
<div data-component="user-profile-computed">
<div class="row">
<div class="col-md-6">
<h5>Input Fields</h5>
<div class="mb-3">
<label class="form-label">First Name:</label>
<input type="text" class="form-control" data-model="firstName" placeholder="Enter first name">
</div>
<div class="mb-3">
<label class="form-label">Last Name:</label>
<input type="text" class="form-control" data-model="lastName" placeholder="Enter last name">
</div>
<div class="mb-3">
<label class="form-label">Username:</label>
<input type="text" class="form-control" data-model="username" placeholder="Optional username">
</div>
</div>
<div class="col-md-6">
<h5>Computed Values</h5>
<div class="card"><div class="card-body">
<p><strong>Full Name:</strong> <span data-bind="fullName" class="text-primary"></span></p>
<p><strong>Initials:</strong> <span data-bind="initials" class="badge bg-secondary"></span></p>
<p><strong>Display Name:</strong> <span data-bind="displayName" class="text-success"></span></p>
<p><strong>Name Length:</strong> <span data-bind="nameLength"></span> characters</p>
<p><strong>Has Full Name:</strong> <span data-bind="hasFullName" class="badge"></span></p>

wildflower.component('user-profile-computed', {

return `${this.firstName} ${this.lastName}`.trim()
},
// Computed property with string manipulation
initials() {
const first = this.firstName.charAt(0).toUpperCase()
const last = this.lastName.charAt(0).toUpperCase()
return `${first}${last}`
},

},
clearAll() {

},
randomize() {
const firstNames = ['Emma', 'Oliver', 'Sophia', 'William', 'Ava', 'James']
const lastNames = ['Smith', 'Johnson', 'Brown', 'Taylor', 'Anderson', 'Wilson']
this.firstName = firstNames[Math.floor(Math.random() * firstNames.length)]
this.lastName = lastNames[Math.floor(Math.random() * lastNames.length)]
this.username = `${this.firstName.toLowerCase()}.${this.lastName.toLowerCase()}`
}
})
Dependency Tracking & Complex Calculations
WildflowerJS automatically tracks dependencies and updates computed properties when dependent state changes:

Caching and Performance
Computed properties are cached and only recalculate when their dependencies change:
- Computed values are cached until dependencies change
- Expensive calculations run only when necessary
- Automatic dependency tracking prevents unnecessary updates
- Multiple bindings to the same computed property share the cached result

Computed Properties in Templates
Use computed properties in data binding by name. No prefix needed. WildflowerJS automatically detects computed properties:
data-bind="fullName". No special syntax needed.
state and computed have a property with the same name, the computed property takes precedence. This allows computed properties to "override" or transform state values when needed.
Computed Properties in Expressions
Unlike some frameworks where computed values require special syntax or function calls, WildflowerJS treats computed properties as first-class citizens:
wildflower.component('user-dashboard', {
state: {
firstName: 'Alice',
lastName: 'Smith',
items: [1, 2, 3],
threshold: 5
},
computed: {
fullName() { return `${this.firstName} ${this.lastName}`; },
itemCount() { return this.items.length; },
hasItems() { return this.items.length > 0; },
isOverThreshold() { return this.items.length > this.threshold; }
}
});
<!-- Computed values work directly in expressions -->
<!-- String concatenation with computed + state -->
<p data-bind="fullName + ' has ' + itemCount + ' items'"></p>
<!-- Ternary expressions mixing computed and state -->
<p data-bind="hasItems ? 'You have ' + itemCount + ' items' : 'No items yet'"></p>
<!-- Boolean logic in conditionals -->
<div data-show="hasItems && itemCount > 2">Many items!</div>
<div data-show="isOverThreshold || itemCount === 0">Edge case</div>
<!-- Computed values in comparisons -->
<span data-bind="itemCount >= threshold ? 'At capacity' : 'Room for more'"></span>
<!-- Computed in class bindings -->
<div data-bind-class="{ 'has-content': hasItems, 'empty': !hasItems, 'over-limit': isOverThreshold }"></div>
<!-- Computed in style bindings -->
<div data-bind-style="{ opacity: hasItems ? '1' : '0.5' }"></div>
This is comparable to Vue's computed + template expressions, Svelte 5's $derived, and Solid's createMemo, but without requiring a build step or special syntax. The computed values simply exist as variables in your expressions.

Best Practices
✅ Do
- Keep computed properties pure (no side effects)
- Use computed properties for derived state
- Cache expensive calculations in computed properties
- Use descriptive names for computed properties
- Return consistent data types
- Track side effects outside computed properties
- Read all potentially-relevant state fields eagerly before any conditional logic (see callout below)
❌ Don't
- Modify state within computed properties
- Make API calls in computed properties
- Use computed properties for actions/events
- Create circular dependencies
- Access DOM elements directly
- Update reactive state synchronously in computed properties
Eager dependency reading for conditional computeds
When a computed reads state behind a conditional (&&, ||, ternary, if/return), eagerly destructure all potentially-relevant fields at the top of the function before any branching. The dependency tracker only records reads that actually execute, so a short-circuited read never gets tracked, and the binding silently won't re-evaluate when that untracked field changes.
⚠️ The short-circuit gotcha
// ❌ Risky: the right side of && only reads when the left is truthy.
// If openField is null on first evaluation, openId is never read and
// never tracked. Later, when only openId changes, the binding misses
// the update.
computed: {
isOpen(item) {
const s = this.state;
return s.openField === 'status' && s.openId === item.id;
}
}
✅ Eager-read pattern
// ✅ Read both fields up front. Both end up tracked as deps,
// regardless of which value would short-circuit the && later.
computed: {
isOpen(item) {
const s = this.state;
const f = s.openField; // always read; always tracked
const id = s.openId; // always read; always tracked
return f === 'status' && id === item.id;
}
}
The symptom of forgetting this is usually non-deterministic UI behavior: the binding wakes up for some state-change sequences and silently misses others. See Conditional reads and dep tracking for the underlying mechanism. This same pattern applies to all runtime-proxy reactive systems (Vue, Solid, MobX, Preact Signals).
Avoiding Circular Dependencies
One common pitfall is creating circular dependencies when computed properties modify state that they also depend on:
⚠️ Circular Dependency Example
// ❌ Bad - Creates infinite loop
computed: {
expensiveCalculation() {
this.calculationCount++ // Modifies state!
return this.data.reduce((a, b) => a + b, 0)
}
}
// State binding triggers reactivity
<span data-bind="calculationCount"></span>
This creates an endless loop: computed property runs → modifies state → triggers reactivity → computed property runs again.
✅ Solution: External Tracking
// ✅ Good - Track side effects separately
computed: {
expensiveCalculation() {
this.trackCalculation('expensive') // External method
return this.data.reduce((a, b) => a + b, 0)
}
},
trackCalculation(type) {
// Use requestAnimationFrame to avoid circular dependencies
requestAnimationFrame(() => {
this.calculationCounts[type]++
})
}
This approach maintains the educational value while preventing infinite loops by deferring state updates to the next frame.
