## What it is
A community-maintained collection of base TSConfig files published as npm packages under the @tsconfig scope, tuned for specific runtime environments like Node versions, Bun, Deno, and frameworks. Projects extend these presets in their own tsconfig.json instead of hand-writing compiler options.

## Use cases
- set up a tsconfig for a node 18 project
- find recommended typescript compiler options for bun
- extend a base tsconfig for create react app
- keep typescript config consistent across projects
- configure tsconfig for deno or next.js
- avoid hand-writing typescript compiler options

## When to choose
- you are starting a TypeScript app and want sane, environment-tuned compiler defaults
- you want community-maintained tsconfig presets you can extend with 'extends'
- you target a specific runtime like Node LTS, Bun, or Deno

## When to avoid
- you need highly customized compiler options beyond what a base preset provides
- you are not using TypeScript at all
- you need a pinned older TypeScript version that the presets do not target

## Facets
- artifact type: dataset
- maturity: active
- function: configuration-management, developer-tools, build-tool
- domain: developer-tools, web-development, frontend, backend
- platform: bun, browser, cross-platform
- tags: tsconfig, typescript, npm-packages, preset-configs, definitely-typed-for-tsconfig, nodejs, deno
