Use npx to require packages without installing, proof-of-concept

require-without-installing.js

#!/usr/bin/env node
const npx = require('libnpx')
const path = require('path')

const packageName = "figlet"
const NPM_PATH = path.join(__dirname, 'node_modules', 'npm', 'bin', 'npm-cli.js')

npx._ensurePackages(packageName, { npm: NPM_PATH })
  .then(results => {
    const package = require(path.join(results.prefix, 'lib', 'node_modules', packageName))
    package('hello', (err, data) => console.log(data))
  })
  .catch(error => console.error(error))
