I am using opentok for video feeding in my application.
How to integrate annotations on opentok using javascript?
As Darshu mentioned, you can use the OpenTok Annotation node module to add annotations to your OpenTok application in JavaScript. You can also find sample applications in JavaScript using OpenTok and OpenTok Annotation package here: https://github.com/opentok/accelerator-sample-apps-js
OpenTok Accelerator Sample Apps for JavaScript
open here soultion available. First download nodejs install on the machine.
This document shows you how to prepare and run the sample application. The app is built using Accelerator Core JS and the following accelerator packs:
Text Chat
Screen Sharing
Annotation

I intend to develop an app for our site but one of the main worry is that I need to use a 3rd party payment gateway that only provides SDK for android in Java and iOS in Objective-C.
I want to know if it is appropriate to use React-Native or Ionic for the app. I am not sure which of these framework supports integration of native integrated and work flawlessly.
Hope someone with experience can help advise on this.
Thanks.
For react-native you can write your native modules for both android(JAVA) and ios(OBJECTIVE-C). It provides you right to write code in module and then register the module for your further use inside your application.
You can read the complete docs from :-
For android https://facebook.github.io/react-native/docs/native-modules-android.html
and for ios https://facebook.github.io/react-native/docs/native-modules-ios.html
I have read some docs and i do not really understand what are the differences between react and ionic frameworks.
Is one of them made from the other ?
I have to store local data. I suppose one of them is just web and javascript so data is only stored on server ? Or is it possible to do local storage with both of them.
Is it possible to host the app on a web server without having a "real" app ?
Thanks
Hi I think that you are a little bit confused. I hope this clarify your doubts:
Ionic framework is a set of tools for create Hybrid apps using html/css and javascript, It is build using apache cordova and Angular 1. In the other hand you have React a library for build rich UX(User experience) web apps.
Ionic is not build on react. They are different purpose tools but you can use that together (Using IONIC 2).
In both cases you can use local storage, but if you want to store data in servers you have to build your own backend to provide data to the app They are front end oriented frameworks(no server side)
You can put Ionic code on a server it is simple JavaScript and HTML but this is not the purpose of the framework and if you do it, you loose the native apis of the device. In the case of React it is just a library and you can use it in an existing project using HTML and Javascript or build your app entirely with it.
You have a long road ahead, hope this help you.
Ionic is an HTML5 mobile app development framework targeted at building hybrid mobile apps. They are essentially small websites running in a browser shell in an app that have access to the native platform layer.
React Native is the next generation of React – a JavaScript code library developed by Facebook and Instagram, which was released on Github in 2013. React Native lets you build mobile apps using only JavaScript.
They have their own way of functioning, below are few points on their differences:
Ionic is a regular web app, written using HTML, CSS, and JavaScript, but it runs in a webview embedded in a native app instead of in a stand-alone mobile browser
React Native has a completely different architecture: instead of writing your UI using web technologies, it uses the React component model to render to native views.
Ionic is a Cordova based app that wrap current web app into a mobile application. It uses the android existing web view to render the app so the file size is quite small
Meanwhile react native create bridge between JavaScript and native component.
When it comes to memory usage, Ionic framework uses more than react native apps
The Ionic app is slower at loading videos because it needs to download from other server, while in react native, it caches the tiles so it loads faster.
When it comes to integration, react native can use every client based JavaScript modules from npm (node package manager) whereas Ionic uses only the Cordova-based code.
Ionic is a framework that creates an idea of writing code only once
React native is not a write once and run anywhere framework, but is popularly touted as a “learn once, write anywhere” framework
Ionic Framework app needs to use device features and APIs through Apache Cordova plugins.
With react native you can access any device component or API
Based on the points above, you can see the difference in their functionalities, so if you want to go for something that creates performant iOS and Android apps that feel at home on their respective platforms ten you can opt for React Native.
And, if you are targeted at building hybrid mobile apps, Ionic is the best choice!
im new to mobile development and i see ionic framework has very big community BUT
i know that ionic uses webview while nativescript generates native components
my question now what nativescript can do ionic cannot do?
in other words what is the powerful points in nativescript that does not exists in ionic
thanks in advance.
Ionic is hybrid, running inside webview which has problem with performance at particular things like even simpler animation, not fully accessible API of native part
Nativescript runs as native app, controlled by JS code but can be used even with native code or even as addon to native app and full access to API of native code
I'm getting started with Sencha Touch via this official tutorial and in the same time I can run the Hello application via the tool Eclipse-ADT Bundle as guided here
But I don't know how to use ADT Bundle to run the Sencha Touch application.
We need to install Phone Gap so that Sencha web page will be provided extra javascripts API to access the device API.
And we also need a way to wrap Sencha web inside an Android native app project. This is done also done by PhoneGap - detail steps are greatly guided here by Andrew Trice from Adobe
I am developing an application targeted only for iOS device(for now) using PhoneGap library and HTML5. This application is going to be only a web page accessed through iOS Safari browser. I am going to use certain features like accessing accelerometer, geolocation, contacts etc of iOS device using PhoneGap library.
Will I get access to all these features without installing anything on the device.
I want to understand how does PhoneGap get access to native features
of the device by just using JavaScript only?
I see there are several useful plugins written for PhoneGap library.
Can I simply use those plugins(js files) into my page without
installing anything on the device? E.g PhoneGap ChildBrowser plugin?
Will I get access to all these features without installing anything on the device.
You will have to build as a native ios app and install it to the device.
I want to understand how does PhoneGap get access to native features of the device by just using JavaScript only?
Phonegap provides a Javascript interface to access hardware features which are actually Objective-C functions. If you look at Phonegap source you'll see a lot of Objective-C code. So it's not only Javascript.

No. They have to be inside an iOS app to be able to work.
It seems like what your after is a way to access the features of an APP only through the browser.
You can access some things using HTML5 e.g.:
Geo location http://html5demos.com/geo
Accelerometer http://menscher.com/teaching/woaa/examples/html5_accelerometer.html
