Filter Sphere - Schema-driven Filtering

Build advanced filtering interfaces powered by Zod schemas.

Quick Start

# React filter UI
pnpm add @fn-sphere/filter zod

Core Concepts

Basic Setup

import {
  FilterSphereProvider,
  FilterBuilder,
  useFilterSphere,
} from "@fn-sphere/filter";
import { z } from "zod";

// 1. Define your data schema with Zod
const schema = z.object({
  name: z.string().describe("Name"),
  age: z.number().describe("Age"),
});

export function FilterBuilder() {
  // 2. use the `useFilterSphere` hook to get the context and predicate
  const { filterRule, predicate, context } = useFilterSphere({
    schema,
    onRuleChange: ({ filterRule }) => {
      console.log("Filter rule changed:", filterRule);
    },
  });

  const data = [
    /* ... */
  ];

  // 4. use the `predicate` to filter the data
  const filteredData = data.filter(predicate);

  return (
    // 3. display the `FilterBuilder` inside the `FilterSphereProvider`
    <FilterSphereProvider context={context}>
      <FilterBuilder />
    </FilterSphereProvider>
  );
}

Project Structure (Recommended)

filter-sphere/
  index.tsx      # Main component wiring everything together
  schema.ts      # Zod schema, default rules, custom functions
  theme.tsx      # Theme via createFilterTheme
  locale.ts      # (Optional) i18n with getLocaleText
