React Search Builder

Centralized state management for search forms.

Strict typing, cross-field validations, and automatic synchronization with the URL or any persistence mechanism.

🛠️ Installation

With Material UI

pnpm add @vaened/mui-search-builder

Headless / Custom UI

pnpm add @vaened/react-search-builder

📋 Problem It Solves

Advanced search forms usually require:

• Bidirectional synchronization between multiple inputs.
• Cross-field validations (ranges, field dependencies).
• Manual parsing of query strings.
• Constant conversion between string, number, Date, etc.
• State persistence across reloads or navigation.

In practice, this logic often ends up scattered across components, effects, and ad-hoc utilities.

React Search Builder centralizes all these responsibilities into a single Store.

💡 Quick Example (Material UI)

A typical Customer Search form with URL persistence, mixed filter types, and an active filters summary.

conststore=useSearchStore({persistInUrl: true});<SearchFormstore={store}onSearch={console.log}spacing={2}><DateRangeFilterstartFieldName="createdFrom"endFieldName="createdTo"startFieldLabel="Created from"endFieldLabel="Created to"/><DateFiltername="lastActivityAt"label="Last activity"/><OptionSelecttype="string[]"name="channels"label="Acquisition channels"items={{web: "Website",referral: "Referral",partner: "Partner"}}/><SearchBarindexes={{fullName: "Name",email: "Email",document: "Document"}}flags={{isActive: "Active",hasDebt: "Has debt",isVip: "VIP"}}defaultIndex="fullName"/><ActiveFiltersBarlimitTags={8}/></SearchForm>;

📦 Packages and Features

The project is split into two complementary packages:

• @vaened/react-search-builder (Core)
  Pure logic and state management. Use it if you want to build your own UI or integrate the system into an existing component library. Detailed package README: packages/react/README.md

  • Universal Integration (FilterFieldController): Connect any UI component (from a simple native <input/> to complex selectors from libraries like AntD or Chakra). You get value, onChange, and errors ready to use.

  • Asynchronous Hydration: Support for async serializers that pause initialization until data is ready and verified, preventing inconsistent states.

  • Declarative Validation: Define complex conditional and cross-field business rules using the when function, keeping your components clean of if/else logic.

  • Performance: When typing in a field, only that component updates. The rest of the form stays static. This keeps the UI smooth even with dozens of filters, avoiding unnecessary re-renders across the app.

  • Data Humanization: Turn technical values (IDs, codes) into user-friendly text. Ideal for filter summaries or search “chips”.

• @vaened/mui-search-builder (UI Kit)
  Ready-to-use components based on Material UI. Designed for the most common use cases in admin dashboards and backoffice apps. Detailed package README: packages/mui/README.md

  • Unified SearchBar: A composed component that integrates three features into one visual row:

    • Query Input: With automatic debounce.
    • Index Select: Lets the user change the search criterion without taking extra UI space.
    • Flags: Quick boolean filters integrated visually.

  • Validated DateRangeFilter: Abstracts the complexity of handling two DatePickers. It automatically enforces range constraints: selecting a start date disables earlier days in the end date, and vice versa, ensuring a valid range.

  • Polymorphic OptionSelect: A flexible wrapper around MUI Select that accepts multiple data shapes. You can pass a simple dictionary or an array of complex objects with accessors (getValue, getLabel), removing the need for manual .map() in JSX.

  • Reactive ActiveFiltersBar: Closes the UX loop by visually showing applied filters. Users can remove individual filters or clear everything with one click, automatically syncing with the URL and the Store.

✨ Design Principles

• 🧠 Headless & Reactive Architecture

  State lives completely decoupled from React’s component tree.

  • Atomic Subscriptions
    Each field subscribes individually to the Store. Typing in an input does not re-render the whole form—only the affected component.

  • Inversion of Control
    Enables communication between sibling components (for example, a Country selector clearing a City selector) without prop drilling.

  Internally, it guarantees concurrent consistency through useSyncExternalStore.

• 🔌 Decoupled Persistence (Persistence Adapters)

  The storage mechanism is completely agnostic to business logic.

  • Interchangeable Adapters
    WindowUrlPersistenceAdapter (included) syncs with window.location, but the architecture supports async adapters for Next.js, React Router, or storage in LocalStorage.

  • Smart Hydration
    The Store manages loading states (isHydrating) and task queues (TaskMonitor), ensuring the form is not interactive until the URL has been parsed and validated correctly.

• 🛡️ Strict Typing and Serialization

  Automatic and transparent data transformation between the persistence layer and the application layer.

  • Declarative Definition
    Configure fields as date, number, boolean, or array variants (number[], string[]).

  • Type Inference
    TypeScript automatically infers the value type returned by hooks based on the field configuration.

• ✅ Validation Oriented to the Filter Domain

  Validation rules are pure and executed in the Store, not in the UI.

  • Composed Rules Native support for complex validation strategies (allOf with failFast or error collection).

  • Domain Validations

    • Structural: required, length
    • Relational: range, after, before (cross-field validation between dates or numbers)
    • Conditional: when (run validations on field A only if field B matches a condition)

📚 Documentation

This repository provides a headless core and a ready-to-use Material UI implementation.
Each package has its own detailed documentation:

• Core (Headless)

  • @vaened/react-search-builder
    Architecture, store, hooks, validation system, and persistence adapters.
    See: packages/react/README.md

• Material UI Kit

  • @vaened/mui-search-builder
    Prebuilt components and real-world examples using Material UI.
    See: packages/mui/README.md

Use the Core package if you need full control over the UI.
Use the MUI package if you use Material UI and want a set of ready-to-use components.
