cordova-common

Expoeses shared functionality used by cordova-lib and Cordova platforms. ## Exposed APIs

events

Represents special instance of NodeJS EventEmitter which is intended to be used to post events to cordova-lib and cordova-cli

Usage:

var events = require('cordova-common').events;
events.emit('warn', 'Some warning message')

There are the following events supported by cordova-cli: verbose, log, info, warn, error.

CordovaError

An error class used by Cordova to throw cordova-specific errors. The CordovaError class is inherited from Error, so CordovaError instances is also valid Error instances (instanceof check succeeds).

Usage:

var CordovaError = require('cordova-common').CordovaError;
throw new CordovaError('Some error message', SOME_ERR_CODE);

See CordovaError for supported error codes.

ConfigParser

Exposes functionality to deal with cordova project config.xml files. For ConfigParser API reference check ConfigParser Readme.

Usage:

var ConfigParser = require('cordova-common').ConfigParser;
var appConfig = new ConfigParser('path/to/cordova-app/config.xml');
console.log(appconfig.name() + ':' + appConfig.version());

PluginInfoProvider and PluginInfo

PluginInfo is a wrapper for cordova plugins' plugin.xml files. This class may be instantiated directly or via PluginInfoProvider. The difference is that PluginInfoProvider caches PluginInfo instances based on plugin source directory.

Usage:

var PluginInfo: require('cordova-common').PluginInfo;
var PluginInfoProvider: require('cordova-common').PluginInfoProvider;
 
// The following instances are equal 
var plugin1 = new PluginInfo('path/to/plugin_directory');
var plugin2 = new PluginInfoProvider().get('path/to/plugin_directory');
 
console.log('The plugin ' + plugin1.id + ' has version ' + plugin1.version)

ActionStack

Utility module for dealing with sequential tasks. Provides a set of tasks that are needed to be done and reverts all tasks that are already completed if one of those tasks fail to complete. Used internally by cordova-lib and platform's plugin installation routines.

Usage:

var ActionStack = require('cordova-common').ActionStack;
var stack = new ActionStack()
 
var action1 = stack.createAction(task1, [<task parameters>], task1_reverter, [<reverter_parameters>]);
var action2 = stack.createAction(task2, [<task parameters>], task2_reverter, [<reverter_parameters>]);
 
stack.push(action1);
stack.push(action2);
 
stack.process()
.then(function() {
    // all actions succeded 
})
.catch(function(error){
    // One of actions failed with error 
})

superspawn

Module for spawning child processes with some advanced logic.

Usage:

var superspawn = require('cordova-common').superspawn;
superspawn.spawn('adb', ['devices'])
.progress(function(data){
    if (data.stderr)
        console.error('"adb devices" raised an error: ' + data.stderr);
})
.then(function(devices){
    // Do something... 
})

xmlHelpers

A set of utility methods for dealing with xml files.

Usage:

var xml = require('cordova-common').xmlHelpers;
 
var xmlDoc1 = xml.parseElementtreeSync('some/xml/file');
var xmlDoc2 = xml.parseElementtreeSync('another/xml/file');
 
xml.mergeXml(doc1, doc2); // doc2 now contains all the nodes from doc1
