CLI Reference

The uglier CLI helps you install, initialize, and manage your ESLint configuration.

Commands

install

npx @gesslar/uglier install

Installs @gesslar/uglier and all required peer dependencies. Detects your package manager automatically (npm, pnpm, yarn, bun).

init <targets...>

npx @gesslar/uglier init node
npx @gesslar/uglier init react cjs-override

Generates an eslint.config.js file with the specified config blocks. Each target maps to a config block name.

If eslint.config.js already exists, the command will warn you.

add <targets...>

npx @gesslar/uglier add cjs-override mjs-override

Adds config blocks to an existing eslint.config.js. Parses the current file and appends the new blocks to the with array.

remove <targets...>

npx @gesslar/uglier remove lints-jsdoc

Removes config blocks from an existing eslint.config.js.

--help

npx @gesslar/uglier --help

Displays usage information and lists all available config blocks with descriptions.

Package manager detection

The CLI automatically detects which package manager your project uses by checking for lock files:

Lock file	Package manager
pnpm-lock.yaml	pnpm
yarn.lock	yarn
bun.lockb	bun
package-lock.json	npm
