@antfu/ni

What is @antfu/ni?

@antfu/ni is a command-line tool that provides a unified interface for package managers like npm, yarn, and pnpm. It simplifies the process of managing dependencies by automatically detecting the package manager used in a project and running the appropriate commands.

What are @antfu/ni's main functionalities?

Install Dependencies

The `ni` command installs dependencies in the current project. It automatically detects the package manager used (npm, yarn, or pnpm) and runs the corresponding install command.

ni

Add a Dependency

The `ni <package>` command adds a new dependency to the project. It detects the package manager and runs the appropriate command to add the specified package.

ni axios

Remove a Dependency

The `nr <package>` command removes a dependency from the project. It detects the package manager and runs the appropriate command to remove the specified package.

nr axios

Upgrade Dependencies

The `nu` command upgrades all dependencies in the project. It detects the package manager and runs the appropriate command to upgrade the dependencies.

nu

Run Scripts

The `ni run <script>` command runs a script defined in the project's package.json file. It detects the package manager and runs the appropriate command to execute the script.

ni run build

Other packages similar to @antfu/ni

npm

npm is the default package manager for Node.js. It provides a wide range of commands for managing dependencies, running scripts, and more. Unlike @antfu/ni, npm does not automatically detect other package managers.

yarn

Yarn is a fast, reliable, and secure dependency management tool. It offers similar functionalities to npm but with a focus on speed and reliability. Yarn does not provide a unified interface for other package managers like @antfu/ni.

pnpm

pnpm is a fast, disk space-efficient package manager. It uses a unique symlink-based approach to manage dependencies. Like npm and yarn, pnpm does not offer a unified interface for other package managers.

npm i in a yarn project, again? F**k!

ni - use the right package manager

# yarn install --frozen-lockfile
# pnpm install --frozen-lockfile

ni -g eslint

# npm i -g eslint
# yarn global add eslint
# pnpm add -g eslint
# bun add -g eslint

# this uses default agent, regardless your current working directory

nr - run

nr dev --port=3000

# npm run dev -- --port=3000
# yarn run dev --port=3000
# pnpm run dev -- --port=3000

nr

# interactively select the script to run
# supports https://www.npmjs.com/package/npm-scripts-info convention

# rerun the last command

nx - execute

nx vitest

# npx vitest
# yarn dlx vitest
# pnpm dlx vitest

nu - upgrade

nu

# npm upgrade
# yarn upgrade
# pnpm update

nu -i

# (not available for npm)
# yarn upgrade-interactive
# pnpm update -i

nun - uninstall

nun webpack

# npm uninstall webpack
# yarn remove webpack
# pnpm remove webpack
# bun remove webpack

nun -g eslint

# npm uninstall -g eslint
# yarn global remove eslint
# pnpm remove -g eslint
# bun remove -g eslint

nci - clean install

nci

# npm ci
# yarn install --frozen-lockfile
# pnpm install --frozen-lockfile

if the corresponding node manager is not present, this command will install it globally along the way.

na - agent alias

na

# npm
# yarn
# pnpm

na run foo

# npm run foo
# yarn run foo
# pnpm run foo

Change Directory

ni -C packages/foo vite
nr -C playground dev

Config

; ~/.nirc

; fallback when no lock found
defaultAgent=npm # default "prompt"

; for global installs
globalAgent=npm

# ~/.bashrc

# custom configuration file path
export NI_CONFIG_FILE="$HOME/.config/ni/nirc"

How?

ni assumes that you work with lockfiles (and you should)

Before it runs, it will detect your yarn.lock / pnpm-lock.yaml / package-lock.json / bun.lockb to know current package manager (or packageManager field in your packages.json if specified), and runs the corresponding commands.
