Check Cordova Version From Javascript

Is there any way to check from Javascript what version of Cordova an app is running? Why I ask: We've upgraded our Cordova from 2.8 to 4.0.2 and the new Cordova JS file does not wo

Manual way

I made a functional hook script which I stored at hooks/setVersion.js. I just tested it now and it works (just in Android, for iOS you just need to replicate the wwwDir)

#!/usr/bin/env nodevar wwwFileToReplace = 'index.html'var fs = require('fs')
var path = require('path')

module.exports = function (context) {
  var projectRoot = context.opts.projectRootconst wwwDir = path.join(projectRoot, 'platforms', 'android', 'app', 'src', 'main', 'assets', 'www')

  var configXMLPath = 'config.xml'loadConfigXMLDoc(configXMLPath, (rawJSON) => {
    var version = rawJSON.widget.$.versionconsole.log('Version:', version)

    var fullfilename = path.join(wwwDir, wwwFileToReplace)
    if (fs.existsSync(fullfilename)) {
      replaceStringInFile(fullfilename, '%%VERSION%%', version)
      console.log(context.hook + ': Replaced version in file: ' + path.relative(projectRoot, fullfilename))
    } else {
      console.error('File does not exist: ', path.relative(projectRoot, fullfilename))
      process.exit(1)
    }
  })
}

functionloadConfigXMLDoc (filePath, callback) {
  var fs = require('fs')
  var xml2js = require('xml2js')
  try {
    var fileData = fs.readFileSync(filePath, 'ascii')
    var parser = new xml2js.Parser()
    parser.parseString(fileData.substring(0, fileData.length), function (err, result) {
      if (err) {
        console.error(err)
        process.exit(1)
      } else {
        // console.log("config.xml as JSON", JSON.stringify(result, null, 2))console.log("File '" + filePath + "' was successfully read.")
        callback(result)
      }
    })
  } catch (ex) {
    console.log(ex)
    process.exit(1)
  }
}

functionreplaceStringInFile (filename, toReplace, replaceWith) {
  var data = fs.readFileSync(filename, 'utf8')

  var result = data.replace(newRegExp(toReplace, 'g'), replaceWith)
  fs.writeFileSync(filename, result, 'utf8')
}

You have also to add in config.xml

<hooksrc="hooks/setVersion.js"type="after_prepare"/>

This script replaces the text %%VERSION%% in a file with the app version from config.xml, so you can have in your index.html file something like

<htmldata-appversion="%%VERSION%%">

and in your JS

const version = document.documentElement.getAttribute("data-appversion");

Solution 2:

You can use device.cordova to get the current version of Cordova.
