package_manager_detector_rs

Package manager detector is based on lock files and the packageManager field in the current project's package.json file.

It will detect your yarn.lock / pnpm-lock.yaml / package-lock.json / bun.lockb / deno.lock to know the current package manager and use the packageManager field in your package.json if present.

Install

Run the following Cargo command in your project directory:

cargo add package_manager_detector_rs

Or add the following line to your Cargo.toml:

[dependencies]
package_manager_detector_rs = "0.2.5"

Usage

To check the file system for which package manager is used:

use package_manager_detector_rs::{detect};

fn main() {
    let pm = detect();
    if pm.is_none() {
        println!("Could not detect package manager")
    }

    println!("{:?}", pm);
    // HandlePackageManagerReturn { 
    //     name: "yarn", agent: "yarn@berry", version: "berry"
    // }
}

Agents and Commands

This package includes package manager agents and their corresponding commands for:

'agent' - run the package manager with no arguments
'install' - install dependencies
'frozen' - install dependencies using frozen lockfile
'add' - add dependencies
'uninstall' - remove dependencies
'global' - install global packages
'global_uninstall' - remove global packages
'upgrade' - upgrade dependencies
'upgrade-interactive' - upgrade dependencies interactively: not available for npm and bun
'execute' - download & execute binary scripts
'execute-local' - execute binary scripts (from package locally installed)
'run' - run package.json scripts

Using Agents and Commands

A resolve_command function is provided to resolve the command for a specific agent.

use package_manager_detector_rs::{resolve_command, detect};

fn main() {
    let pm = detect();
    if pm.is_none() {
        println!("Could not detect package manager")
    }

    println!("{:?}", pm);
    // HandlePackageManagerReturn {
    //     name: "yarn", agent: "yarn@berry", version: "berry"
    // }

    let agent = pm.unwrap().agent;
    let get_command = resolve_command(&agent, "add", vec!["@antfu/ni"]);
    let get_command = get_command.unwrap();

    println!("Detected the {} package manager. You can run a install with {} {}", &agent, get_command.command, get_command.args.join(" "))
    // Detected the yarn@berry package manager. You can run a install with yarn add @antfu/ni
}

You can check the source code for more information.
