## What it is
Oboe.js is a JavaScript library for streaming JSON parsing, letting web applications use parsed objects before the HTTP response completes. It combines DOM-like pattern matching with SAX-style streaming and works in both browsers and Node.

## Use cases
- parse large JSON responses without waiting for the request to finish
- load JSON trees larger than available memory
- transform JSON while it is being streamed
- demarshal streamed JSON into OOP models
- progressively render data from slow or long-running API responses

## When to choose
- you need to start consuming JSON before the HTTP response completes
- you must parse JSON documents too large to fit in memory
- you want a small dependency-free streaming JSON parser for browser or Node

## When to avoid
- starting a new project, since the repository is archived and unmaintained since ~2020
- you need modern async-iterator-based streaming APIs or TypeScript support
- you need guaranteed bug fixes or compatibility with the latest runtimes
