The guarantee of Cordova development is very beguiling: you can utilize your current HTML + JavaScript + CSS application to assemble cross-stage mobile applications for iOS, Android, Windows Phone, and different stages.
What is Apache Cordova?
Apache Cordova is a free and open-source stage for building native mobile applications utilizing HTML, CSS, and JavaScript. This permits you to focus on different stages with only one codebase.
Fundamentally, Cordova is a wrapper, an application that has an implanted internet browser where your web application is stacked.
Installing and setting up Apache Cordova
Before introducing and running anything identified to Cordova, you should introduce the SDK convert for every stage that you mean to fabricate your application for. Right now, I will concentrate on iOS and Android; in any case, the procedure for different stages is very comparative.
You will require a Mac PC with Xcode to indicate iOS as the objective stage, and the Android SDK to focus on the Android stage.
To start with, introduce the Cordova command-line utility by running the accompanying command:
npm introduce – g Cordova
Make another Cordova project by running the accompanying command, where [your-application name] is where the application will be made:
Cordova makes your-application name com.example.my app MyAppName
Peruse the project envelope to include the stages that you need to help. To do this, when you are in the project folder, run the accompanying command for every stage you need to include:
Cordova stage include [platform]
Where [platform] can be:
ios
android
windows
wp8
blackberry10
fire foxes
amazon-fire os
Each time you run the stage, include command; it will add essential documents to construct applications for the predetermined stage. In the wake of running the above command, you should discover an organizer named ios containing .xcodeproj records and a lot of different documents.
Porting your web application to Cordova
In your project envelope, you should discover the/www index. This is the place your web application is found.
For this model, we utilized the TodoMVC Vanilla JavaScript model that you can download from here. Make sure to run npm introduce to get the application conditions.
Your application’s index.html body content goes into the assortment of/www/index.html. Play out these three straightforward strides to refresh it:
Update the leader of the document cautiously so as not to evacuate or change Cordova’s required meta labels, yet add the components necessary to your application. Right now, we included our application’s title, CSS references, and the charset meta tag.
Update the body content with your application content.
Add the references to your application’s required .js documents (regularly, toward the finish of the body).
The/js/index.js incorporates capacities that are required for Cordova. You simply need to call your application to init rationale inside the on-device ready technique, as appeared in the model beneath:
var application = {
instate: work() { … }
bindEvents: work() { … }
onDeviceReady: work() {
/Your application init code
…
}
};
app.initialize();
As the TodoMVC is exceptionally straightforward, only guaranteeing that the cordova.js and index.js records are executed before the application rationale is adequate.
At last, all the CSS documents, pictures, and JavaScript records ought to be moved to the relating organizer inside the/www/envelope.
Include facilitated website page as an application
On the off chance that your application is as of now facilitated on a server, changing over your web application is extremely simple autonomous of the structure and dialects used to make it.
Include the discoursed and system data plugins to your application by running the accompanying commands:
Cordova plugin include Cordova-plugin-discoursed
Cordova plugin include Cordova-plugin-arrange data
To do it, after the on-device ready occasion happens, simply explore the URL of your facilitated application, and that is it.
This appears in the accompanying code:
Proceeding with the ToDoMVC application test, we included this code at the base of the app.js record.
<script>
work onDeviceReady() {
in the event that (navigator.connection.type == Connection.NONE) {
navigator.notification.alert(‘An web association is required to proceed’);
} else {
window.location=”http://www.myapp.com”;
}
}
document.addEventListener(“deviceready”, onDeviceReady, bogus);
</script>
Furthermore, as the facilitated application will require a web association, we added a basic check to confirm that this condition is fulfilled.
Including native highlights
Most native highlights can be effectively added to your Cordova application by utilizing its plugin framework. You can peruse the Cordova Plugin APIs page to see the most utilized plugins.
Right now, we will tell you the best way to add geolocation backing to make your applications area mindful.
To begin with, introduce the Cordova-plugin-geolocation plugin by running the accompanying command:
Cordova plugin include Cordova-plugin-geolocation
Once the plugin is introduced, simply add a call to the navigator.geolocation.getCurrentPosition strategy in your application’s code and that is it.
navigator.geolocation.getCurrentPosition(geolocationSuccessCallback,
[geolocationError],
[geolocationOptions]);
Note: You can just call the getCurrentPosition technique once the on-device ready occasion has been terminated.
Coming up next is an extremely straightforward case of code that gets the immediate area.
var onSuccess = function(position) {
console.log(‘Latitude: ‘ + position.coords.latitude + ‘\n’ +
‘Longitude: ‘ + position.coords.longitude+ ‘\n’);
};
var onError = work onError(error) {
console.log(‘code: ‘ + error.code + ‘\n’ +
‘message: ‘ + error.message + ‘\n’);
}
navigator.geolocation.getCurrentPosition(onSuccess, onError);
Testing your Cordova application
To the Best convert website to iphone app, you will require a gadget or emulator of the relating stage. Construct your application by running the accompanying command:
Cordova assemble [platform]
On the off chance that you determine a stage, just that stage will be manufactured; in any case, ultimately included scenes will be fabricated individually.
The accompanying subsections demonstrate directions to introduce and set up iOS and Android emulators.
Introducing an iOS test system
If you are utilizing a Mac PC, you can introduce the iOS test system by running the accompanying command:
sudo npm introduce – g ios-sim
Making the Android virtual gadget
When you have introduced the Android SDK and arranged the environment factors, run the accompanying command to list the easy targets:
android list targets
Note the id number of the ideal objective and use it in the accompanying command to make the Android virtual gadget.
android make and – name my Cordova – target 1
Note: If different ABIs are introduced for the chose to target, you should run the command indicating one ABI utilizing the – abi parameter. The accessible ABIs are recorded when the make and command come up short or using the android list targets command.
Attempt the emulator by running:
Cordova imitate Android
Running the application
If the manufacturer worked out in a good way and the emulators are introduced, run the accompanying command indicating the ideal stage to begin the application:
Cordova run [platform]
Six hints for moving your application
Tips for making your Cordova application
In light of our involvement in this kind of application, we made the accompanying rundown of tips for making your own Cordova applications.
Single Page Apps work better. Recall that the prescribed design for Cordova applications is Single-Page Applications (SPAs). Along these lines, the entirety of the assets is possibly stacked once when the application convert begins and can remain in the web see for whatever length of time that the iPhone application is running. What’s more, with SPAs, the client won’t have page reloads, which are mostly not common for native applications.
Make your application responsive. Guarantee your application is responsive, in that it adjusts nimbly to various gadgets and goals. Utilizing CSS media questions is a decent methodology for this.
Include smooth advances when required. On the off chance that your application isn’t SPA, add increases when exploring different pages, so the route goes unnoticed.
Choose what structure factors you will bolster. Will you support just mobile telephone or tablet structure factors, or give a responsive, widespread encounter? Similarly, as every stage and stage rendition will present an additional degree of exertion, each structure factor/breakpoint setting will present another degree of effort for originators, engineers, and, in the long run, analyzers.
Include Offline Support. Choose if it is essential to include disconnected help. While some applications don’t require any web access for exemplary conduct, some do (facilitated applications, for instance). Indeed, even some specific highlights of the application may need a web. Consider the client experience of your application when no web association is available. For instance, a few highlights, for example, sharing, can be impaired when disconnected. You can utilize the Cordova Network Information plugin to identify the association type and to deal with on the web and disconnected discovery.
Test on gadgets. It is practically required to have in any event one physical device for every stage/form that you are supporting. There are emulators and test systems that can assist you with testing the application and recognize some significant issues. However, nothing is comparable to having a genuine gadget for testing.
