## What it is
Bodybuilder is a small JavaScript library for building Elasticsearch query bodies with a simple, chainable, predictable API. It supports the full Elasticsearch query DSL including queries, filters, aggregations, and suggestions, with compatibility options for Elasticsearch 1.x.

## Use cases
- build complex elasticsearch queries programmatically
- construct elasticsearch query DSL without writing raw JSON
- compose nested queries and aggregations in JavaScript
- generate elasticsearch filter and aggregation bodies
- maintain readable elasticsearch query code in Node.js apps

## When to choose
- you write Elasticsearch queries in JavaScript/Node.js and want a fluent builder instead of hand-written JSON
- you need to dynamically compose queries, filters, and aggregations at runtime
- you want a lightweight dependency with full query DSL coverage

## When to avoid
- you use a different search engine than Elasticsearch
- your queries are static and simple enough to write as plain JSON objects
- you need a client that also handles connections and requests (bodybuilder only builds bodies, it does not send them)

## Facets
- artifact type: library
- maturity: stable
- function: search-engine, developer-tools
- domain: developer-tools, apis
- platform: cross-platform
- tags: elasticsearch, query-builder, querydsl, dsl, search, nodejs, javascript
