## What it is
Vercel's shared engineering style guide packaged as @vercel/style-guide, providing composable ESLint, Prettier, and TypeScript configs. The repository has been archived and sunset, with configurations kept public for reference only.

## Use cases
- apply Vercel's code style to my JavaScript project
- shared eslint config for a Next.js app
- prettier config used by Vercel
- standardize linting rules across a team
- typescript eslint config for react projects
- set up jest and vitest linting rules

## When to choose
- you want to match Vercel's internal code style exactly
- you need a reference for well-composed ESLint flat/legacy configs
- you maintain an existing project already depending on @vercel/style-guide

## When to avoid
- starting a new project, since the repo is archived and no longer maintained
- you need updated rules for new ESLint or TypeScript versions
- you want actively supported community configs like eslint-config-next or neostandard

## Facets
- artifact type: library
- maturity: abandoned
- function: linter, formatter, developer-tools
- domain: developer-tools, web-development, version-control
- platform: -
