jquery query builder

The tool is a client-side query builder library designed for web applications that need to construct complex, boolean filtering logic without server-side helpers. It models filters as rules as leaf conditions and groups as nested boolean wrappers. Developers configure a data schema of available fields and operators, then compose conditional logic that can be evaluated locally or serialized for API requests.\n\nConceptually, each leaf represents a condition like field operator value. Nested groups allow nesting with two or more levels. The library validates input types (string, number, date) and ensures required inputs exist before serialization. The canonical output is a JSON payload suitable for REST or GraphQL, with optional textual representations that some backends accept.\n\nWho benefits: frontend engineers building analytics dashboards, CRM filters, product catalogs, and any app that exposes advanced search. Unique value lies in client-side processing, zero server round-trips for initial filtering, and a clean API for exporting rules to common formats. It also supports presets and extension points for custom operators.\n\nCore features include a rule builder model, group nesting, a library of operators (equals, not equals, in, contains, greater than, etc.), field metadata, type-aware validation, and serialization to a payload. Use cases include filtering customer records, product inventories, and event logs, with easy integration into existing data flows.
