unpkg importer for scriptable.app, downloads modules to `iCloud Drive/Scriptable/modules`

unpkg.js

// unpkg: like NPM but not as good
//        and available in Scriptable
//
// Examples:
// - const _ = await unpkg('lodash')
// - const CryptoJS = await unpkg('crypto-js')
// - const OAuth = await unpkg('oauth-1.0a')

const unpkg = (package, file, version) => {
  return new Promise((callback) => {
    const jsFile = file || package
    const pkgVersion = version ? `@${version}` : ''
    const fm = FileManager.iCloud()
    const modulesPath = fm.joinPath(fm.documentsDirectory(), 'modules/')
    const modulePath = fm.joinPath(modulesPath, `${package}${pkgVersion}/`)
    const filePath = fm.joinPath(modulePath, `${jsFile.split('/')[jsFile.split('/').length-1]}.js`)

    if (!fm.fileExists(modulePath)) {
      fm.createDirectory(modulePath, true)
    }
    if (!fm.fileExists(filePath) ) {
      const req = new Request(`https://unpkg.com/${package}${pkgVersion}/${jsFile}.js`)
      req.loadString().then(res => {
        fm.writeString(filePath, `${res}`).then(() => {
          callback(importModule(filePath))
        })
      })
    } else {
      fm.downloadFileFromiCloud(filePath).then(() => {
        callback(importModule(filePath))
      })
    }
  })
}

module.exports = unpkg

Great module, that will come in very handy. You can simplify lines 16 to 21 by using Scriptable’s ability to create intermediate directories when using createDirectory, i.e. this will have the same effect:

if (!fm.fileExists(modulePath)) fm.createDirectory(modulePath, true)

oh cool, thanks! i was hoping that was an option
