# ni



**ni** - use the right package manager



#### Rewrite using Rust language, no runtime, no dependencies, can be installed and used, refer to @antfu/ni, specific usage should be consistent with @antfu/ni



### [@antfu/ni](https://github.com/antfu/ni)



# Install



## Using Cargo (Linux/macOS/Windows)



```bash

cargo install npack

```



## Using a script (macOS/Linux)



For bash, zsh and fish shells, there's an automatic installation script.



First ensure that curl and unzip are already installed on you operating system. Then execute:



```bash

curl https://ni.zhazhazhu.me/install.sh | bash

```



npm · yarn · pnpm · bun







### `ni` - install



```bash

ni



# npm install

# yarn install

# pnpm install

# bun install

```



```bash

ni vite



# npm i vite

# yarn add vite

# pnpm add vite

# bun add vite

```



```bash

ni @types/node -D



# npm i @types/node -D

# yarn add @types/node -D

# pnpm add -D @types/node

# bun add -d @types/node

```



```bash

ni --frozen



# npm ci

# yarn install --frozen-lockfile (Yarn 1)

# yarn install --immutable (Yarn Berry)

# pnpm install --frozen-lockfile

# bun install --no-save

```



```bash

ni -g eslint



# npm i -g eslint

# yarn global add eslint (Yarn 1)

# pnpm add -g eslint

# bun add -g eslint



# this uses default agent, regardless your current working directory

```







### `nr` - run



```bash

nr dev --port=3000



# npm run dev -- --port=3000

# yarn run dev --port=3000

# pnpm run dev --port=3000

# bun run dev --port=3000

```



```bash

nr



# interactively select the script to run

# supports https://www.npmjs.com/package/npm-scripts-info convention

```



```bash

nr -



# rerun the last command

```







### `nlx` - download & execute



```bash

nlx vitest



# npx vitest

# yarn dlx vitest

# pnpm dlx vitest

# bunx vitest

```







### `nu` - upgrade



```bash

nu



# npm upgrade

# yarn upgrade (Yarn 1)

# yarn up (Yarn Berry)

# pnpm update

# bun update

```



```bash

nu -i



# (not available for npm & bun)

# yarn upgrade-interactive (Yarn 1)

# yarn up -i (Yarn Berry)

# pnpm update -i

```







### `nun` - uninstall



```bash

nun webpack



# npm uninstall webpack

# yarn remove webpack

# pnpm remove webpack

# bun remove webpack

```



```bash

nun -g silent



# npm uninstall -g silent

# yarn global remove silent

# pnpm remove -g silent

# bun remove -g silent

```







### `nci` - clean install



```bash

nci



# npm ci

# yarn install --frozen-lockfile

# pnpm install --frozen-lockfile

# bun install --no-save

```



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







### `na` - agent alias



```bash

na



# npm

# yarn

# pnpm

# bun

```



```bash

na run foo



# npm run foo

# yarn run foo

# pnpm run foo

# bun run foo

```







### Global Flags



```bash

# ?               | Print the command execution depends on the agent

ni vite ?



# -C              | Change directory before running the command

ni -C packages/foo vite

nr -C playground dev



# -v, --version   | Show version number

ni -v



# -h, --help      | Show help

ni -h

```







### Config



```ini

; ~/.nirc



; fallback when no lock found

defaultAgent=npm # default "prompt"



; for global installs

globalAgent=npm

```



```bash

# ~/.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](https://github.com/antfu/ni/blob/main/src/agents.ts).



### Trouble shooting



#### Conflicts with PowerShell



PowerShell comes with a built-in alias `ni` for the `New-Item` cmdlet. To remove the alias in your current PowerShell session in favor of this package, use the following command:



```PowerShell

'Remove-Item Alias:ni -Force -ErrorAction Ignore'

```



If you want to persist the changes, you can add them to your PowerShell profile. The profile path is accessible within the `$profile` variable. The ps1 profile file can normally be found at



- PowerShell 5 (Windows PowerShell): `C:\Users\USERNAME\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1`

- PowerShell 7: `C:\Users\USERNAME\Documents\PowerShell\Microsoft.PowerShell_profile.ps1`

- VSCode: `C:\Users\USERNAME\Documents\PowerShell\Microsoft.VSCode_profile.ps1`



You can use the following script to remove the alias at shell start by adding the above command to your profile:



```PowerShell

if (-not (Test-Path $profile)) {

  New-Item -ItemType File -Path (Split-Path $profile) -Force -Name (Split-Path $profile -Leaf)

}



$profileEntry = 'Remove-Item Alias:ni -Force -ErrorAction Ignore'

$profileContent = Get-Content $profile

if ($profileContent -notcontains $profileEntry) {

  ("`n" + $profileEntry) | Out-File $profile -Append -Force -Encoding UTF8

}

```



#### `nx` and `nix` is no longer available



We renamed `nx`/`nix` to `nlx` to avoid conflicts with the other existing tools - [nx](https://nx.dev/) and [nix](https://nixos.org/). You can always alias them back on your shell configuration file (`.zshrc`, `.bashrc`, etc).



```bash

alias nx="nlx"

# or

alias nix="nlx"

```
