## What it is
kyt is a web app configuration toolkit from The New York Times that encapsulates build, dev server, testing, and linting setup for JavaScript apps behind a single CLI. It manages Webpack, Babel, ESLint, and Jest configuration so developers can focus on app architecture instead of tooling.

## Use cases
- bootstrap a new javascript web app without writing webpack config
- set up babel and eslint presets for a react project
- run a dev server with hot reloading for client and server code
- configure jest for unit testing a js app
- manage build tooling for an isomorphic react app
- escape webpack and babel configuration hell

## When to choose
- starting a legacy-style node/react web app and wanting an opinionated all-in-one toolchain
- you want webpack, babel, eslint, and jest preconfigured and overridable from one config file

## When to avoid
- starting a new project today - the project is officially deprecated with no support or releases
- you prefer modern tooling like vite, next.js, or a maintained starter kit
- you need fine-grained control over your build pipeline from day one

## Facets
- artifact type: framework
- maturity: abandoned
- function: build-tool, cli, testing, linter
- domain: web-development, frontend, developer-tools
- platform: cli, cross-platform
- tags: webpack, babel, eslint, jest, zero-config, deprecated, isomorphic-rendering, nodejs
