l1lith / fly-install

Tool for managing NPM dependencies programmatically

Fly Install

Manage NPM dependencies during runtime

Exports

There are two main classes, one for installing dependencies to existing projects, and another for temporarily installing dependencies. All of the installation methods are async.

FlyInstaller

The FlyInstaller installs dependencies to an existing package.json, and it defaults to the working directory of the node process.

const {FlyInstaller} = require('fly-install')

async run(){
    const installer = new FlyInstaller()
    console.log(installer.installRequire('react')) // Returns the react package even if it wasn't previously installed
}

TempInstaller

The TempInstaller is the same as the FlyInstaller except it will automatically install it's dependencies to a temporary directory (they are deleted when the process exits).

Installer Methods

Both the TempInstaller and FlyInstaller have the same methods described below:

install

Installs the package (but does not return it)

installRequire

Installs the package if it is not already installed, and returns the package either way

require

Returns an installed package

uninstall

Uninstalls a package
