npm
or yarn
, what does this project use? Or maybe it's pnpm? Or Bun? Well, let's just use ni
!
Is this a new package manager? No, no, don't worry ^^'
ni
is a simple tool that will try to identify which package manager is in use in the current project, and then run the corresponding command.
How does it work?
From the docs:
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.
In case you were wondering if that weird package-lock.json
file that appears to change unexpectedly on npm install
is needed or not, it indeed is!
Demo
I recorded a short demo to show how cool this tool is, you can watch it here:
Installation
Assuming you already have at least npm globally installed:
npm i -g @antfu/ni
Usage
You just opened a new project and you're ready to install the dependencies. Just type ni
and you're good to go! In the video demo I show it in a real use case.
Supported commands
Here's a description of all currently supported commands. In case something changes and this gets outdated, you can always check the full list on the project's README.
ni
- Install dependencies
Same as npm install
.
You can run it with no arguments to get the full dependencies, or with a package name to install it.
ni
ni react
You can also set the -D
flag to install as a dev dependency.
ni -D prettier
nr
- Run scripts
Same as npm run
.
You can run commands in your package.json scripts.
nr start
nr build
nlx
- Download and execute a package
Same as npx
.
nlx gitignore node
Fun fact, it was originally called nx
but then it was renamed to nix
... and then again to nlx
, to avoid confusion with other existing tools.
nu
- Upgrade dependencies
Same as npm upgrade
.
Upgrades all your packages to the latest version.
nu
nun
- Uninstall dependencies
Same as npm uninstall
.
nun husky
This will remove your package from package.json
and uninstall it from node_modules
.
nci
- Clean install dependencies
Same as npm ci
.
This will remove your node_modules
folder and install all your dependencies again.
nci
na
- Alias for the current manager
Same as npm
... when you don't know you're using npm!
na run test
It will use the correct package manager to forward the command.
Conclusion
As an Open Source contributor it happens quite often to switch between projects that use different package managers. This tool is a great way to avoid having to remember which one is used where.
Even if most of the time npm is the right one, just typing ni or nr is faster anyway.
I hope you'll find this useful too!

Thanks for the great post
Glad you like it!
Next step: support package managers for Python/Java/Rust/...
Just kidding :)
I mean, if there's not one... time to create a new repo on GitHub :D
Why not use Volta? This tool are pin node and package manager vesions and allow to transparent use needed version.
Also as I think if somone combine this tools it would be awesome.
