Getting Started

When switching between JavaScript projects, it's often easy to forget which package manager should be used. JavaScript package managers aren't quite compatible either and each one resolves dependencies differently, so accidentally installing with npm could cause a yarn (classic or berry), pnpm or bun project to break.

swpm is a CLI that intends to solve this problem by unifying the most used commands for the most common Node Package Managers into one. It will recognize the Package Manager used on the project and automatically will translate those commands.

This is an example of how #swpm works. The same command, no matter the package manager used on the project.

swpm-example

Note:
We will start with most used command, then other commands will be added gradually.
Track the command progress implementation on CHEATSHEET.

Progress: 90% of commands included.

Prerequisites

What things you need to install?

Installing

Install as global with any of this package managers

Package Manager Install Command
npm npm install swpm --global
yarn yarn global add swpm
pnpm pnpm install swpm --global
bun bun install -g swpm
volta volta install swpm

swpm update [<package>] [args]

Aliases: up, ud

Args Alias Description
--global -g Update the current package context as a global package

Shared Commands

There are commands that don't need the swpm translation tool, because share the same structure as all package managers.

Init

init or create can be used to set up a new or existing package.

swpm init [--yes]

Flags

Flags are important to swpm and swpx because can modify or set his behavior.

Use

The <swpm|swpx> --use flag allows you to choose your Package Manager for a project.

swpm <command> [args] --use <npm|yarn[@berry]|pnpm|bun>
swpx <command> [args] -u <npm|yarn[@berry]|pnpm|bun>

It will run the command using the selected Package Manager, no matter the swpm property in your package.json.

Info:
Previously it will ask to run the set command when use yarn:
yarn set version classic for yarn yarn set version berry for yarn@berry

Pin

The swpm --pin flag allows you to choose your Package Manager for a project.

swpm --pin <npm|yarn[@berry]|pnpm|bun>
swpm -p <npm|yarn[@berry]|pnpm|bun>

It will store the pinned Package Manager in the package.json file, so you can commit your choice of tools to version control:

{
+ "swpm": "<package-manager-name>"
}

Info:
Additionally it will ask to run the set command when pin yarn:
yarn set version classic for yarn yarn set version berry for yarn@berry

You also can set it manually. Just take care writing a valid Package Manager: npm, yarn[@berry], pnpm or bun. And also remember to run the set command for yarn projects.

Unpin

The swpm --unpin flag allows you to remove the current pinned Package Manager for a project.

swpm --unpin

It will remove the pinned Package Manager in the package.json file.

Test

The <swpm|swpx> --test flag show the equivalent command using the selected Package Manager, but it will not run the command

swpm <command> [args] --test <npm|yarn[@berry]|pnpm|bun>
swpm <command> [args] -t <npm|yarn[@berry]|pnpm|bun>
swpx <command> -t <npm|yarn[@berry]|pnpm|bun>

It will show the command using the selected Package Manager, no matter the swpm property in your package.json.

Mute

The <swpm|swpx> --mute flag hide the package manager command translation.

swpm <command> [args] --mute
swpx <command> [args] --mute

Alias

The <swpm|swpx> --alias flag show the command aliases available.

swpm --alias
swpx --alias

Info

The <swpm|swpx> --info flag show the current Package Manager used and some versions information.

swpm --info
swpx --info

It will search firs the swpm property on the package.json file, and if doesn't not found it, will try to infer the Package Manager in use with help of the lock's file.

Back to menu


Default

You can set a default or global pin Package Manager in order to avoid the --use flag on paths where no exist a package.json or --pin flag on each project.

Create an SWPM environment variable with one of this values <npm|yarn[@berry]|pnpm|bun>.

OS Command
win setx SWPM "<npm|yarn[@berry]|pnpm|bun>"
macOS echo 'export SWPM="<npm|yarn[@berry]|pnpm|bun>"' >> <~/.bash_profile|~/.zshrc>
linux echo 'export SWPM="<npm|yarn[@berry]|pnpm|bun>"' >> <~/.bash_profile|~/.zshrc>

FAQ

How infer the Package Manager?

swpm and swpx search some characteristics following this order.

Icon Stage
📌 Search the swpm property pinned on package.json file
📦 Search the packageManager property on package.json file
🔒 Search for a lock file
🌐 Search a SWPM environment variable

What can I use as Package parameter?

The <package> parameter should follow one of these structures:

[<@scope>/]<name>
[<@scope>/]<name>@<tag>
[<@scope>/]<name>@<version>
[<@scope>/]<name>@<version range>
<alias>@npm:<name>
<git-host>:<git-user>/<repo-name>
<git repo url>
<tarball file>
<tarball url>
<folder>

Monorepos

swpm is compatible with monorepos. You can run it from any subdirectory and it will search upwards until it finds the closest package.json and lock file.

Non documented commands

swpm is not restrictive, if a command translations was not included yet, you can write the command as the package manager expect, then swpm will try to infer the package manager and preserve the rest of the command and arguments without changes and run them.

But, if you found one of this cases, please open a command compatibility issue.

Alternatives

A minimalistic solution focus only in the most common used commands:
