What is cordova.js and why do you need it?
If you are developing a mobile app with HTML, CSS, and JavaScript, you might have heard of Apache Cordova. Cordova is a framework that allows you to use web technologies to create native-like apps for various platforms, such as Android, iOS, Windows, etc. Cordova also provides a set of APIs and plugins that let you access native features of the device, such as camera, contacts, geolocation, etc.
But how does Cordova work? How does it bridge the gap between web and native? The answer is cordova.js. This is a JavaScript file that acts as a glue between your web code and the native code. It provides a common interface for all platforms, so you don't have to worry about platform-specific differences. It also handles the communication between your web code and the native code, using a mechanism called exec.

How to find and download the cordova.js file for your platform
Using the Cordova command-line tool
The easiest way to find and download the cordova.js file for your platform is to use the Cordova command-line tool. When you add a platform to your project using cordova platform add, it automatically generates the cordova.js file for that platform under the platforms folder. For example, if you added android as a platform, you can find the cordova.js file under platforms/android /platform_www/cordova.js. You can copy this file to your project's www folder, or any other folder you prefer.
Alternatively, you can use the cordova prepare command to copy all the platform-specific files, including cordova.js, to your project's www folder. This is useful if you want to keep your project's www folder in sync with the platforms folder.
Using the Cordova GitHub repository
Another way to find and download the cordova.js file for your platform is to use the Cordova GitHub repository. You can clone or download the cordova-js repository from . This repository contains the source code of cordova.js for all platforms, as well as the tools to build it.
Once you have cloned or downloaded the repository, you can find the cordova.js file for your platform under the pkg folder. For example, if you want the cordova.js file for android, you can find it under pkg/android/cordova.js. You can copy this file to your project's www folder, or any other folder you prefer.
If you want to build the cordova.js file from the source code, you can follow the instructions in the README.md file of the repository. You will need to install some dependencies, such as grunt and jasmine, and run some commands, such as grunt compile:android. This will generate the cordova.js file under the pkg folder.
Using the PhoneGap web build service
A third way to find and download the cordova.js file for your platform is to use the PhoneGap web build service. PhoneGap is a distribution of Cordova that provides some additional features and tools, such as a web-based service that lets you build your app online without installing any SDKs or tools on your computer.
To use the PhoneGap web build service, you need to sign up for a free account at . Then, you can upload your project's zip file or connect it to a GitHub repository. The service will automatically include the correct cordova.js file for each platform that you select. You can then download the built app for each platform, or scan a QR code to install it on your device.
The advantage of using the PhoneGap web build service is that you don't have to worry about installing or updating any SDKs or tools on your computer. The disadvantage is that you need an internet connection and a PhoneGap account to use it.
How to include the cordova.js file in your HTML page
Once you have downloaded the cordova.js file for your platform, you need to include it in your HTML page. This is very simple: just use a script tag to load the cordova.js file before any other script tags that use Cordova APIs or plugins. For example:
<html> <head> <script type="text/javascript" src="cordova.js"></script> <script type="text/javascript" src="myapp.js"></script> </head> <body> <!-- Your app content here --> </body> </html>
Note that you don't have to specify the platform name in the src attribute of the script tag. The cordova.js file will automatically detect the platform and load the appropriate code.
Another important thing to note is that you need to wait for the deviceready event before using any Cordova APIs or plugins. This event signals that Cordova has finished loading and is ready to communicate with the native code. You can listen for this event using document.addEventListener. For example:
<script type="text/javascript"> document.addEventListener("deviceready", onDeviceReady, false); function onDeviceReady() // Now you can use Cordova APIs and plugins </script>
If you don't wait for the deviceready event, you might get errors or unexpected results when using Cordova APIs and plugins.
How to use Cordova APIs and plugins with cordova.js
The cordova.js file provides two main ways to use Cordova APIs and plugins: cordova.exec and require.
The cordova.exec method is a low-level function that allows you to execute native code from JavaScript . It takes four parameters: a success callback, an error callback, a service name, and an action name. The service name and the action name are used to identify the native code that you want to execute. The success callback and the error callback are functions that will be called when the native code returns a result or an error. You can also pass optional arguments to the native code as an array after the action name. For example:
<script type="text/javascript"> cordova.exec(onSuccess, onError, "Camera", "takePicture", [options]); function onSuccess(imageData) // Do something with the image data function onError(error) // Handle the error </script>
The cordova.exec method is useful when you want to create your own plugins or use custom native code. However, it is not very user-friendly or intuitive. That's why Cordova also provides a higher-level way to use Cordova APIs and plugins: the require function.
The require function is a common JavaScript pattern that allows you to load modules and access their exports. Cordova uses this function to expose its APIs and plugins as modules that you can require and use in your code. For example, if you want to use the camera API, you can do something like this:
<script type="text/javascript"> var camera = require("cordova-plugin-camera"); camera.getPicture(onSuccess, onError, options); function onSuccess(imageData) // Do something with the image data function onError(error) // Handle the error </script>
The require function is much more convenient and readable than the cordova.exec method. It also handles the deviceready event for you, so you don't have to wait for it before using Cordova APIs and plugins. However, you need to make sure that you have installed the plugins that you want to use with cordova plugin add, or they will not be available for require.
