Titanium SDK

Titanium SDK is an open-source framework that allows the creation of native mobile applications on platforms iOS and Android from a single JavaScript codebase. It is presently developed by non-profit software foundation TiDev, Inc.

In February 2013, Business Insider estimated that 10% of all smartphones worldwide ran Titanium-built apps. , Titanium had amassed over 950,000 developer registrations.

The core component of the Titanium software ecosystem is the Apache-licensed software development kit, Titanium SDK. Alloy, a Titanium-based model–view–controller framework, is a related project presently maintained and developed by TiDev, Inc for use with the Titanium SDK.

Titanium SDK was originally developed and maintained by Appcelerator, Inc, then later by Axway, Inc after Axway purchased Appcelerator in 2016. Today the Titanium SDK and related projects are developer-maintained under direction of non-profit Alabama corporation TiDev, Inc. based in Centreville, Alabama.

History
When it was introduced in December 2008, Titanium was intended for developing cross-platform desktop applications and was sometimes compared to Adobe Air. However, it added support for developing iPhone and Android mobile applications in June 2009, and in 2012, Titanium Desktop was spun off into a separate, community-driven project named TideSDK. Support for developing iPad-based tablet apps was added in April 2010. BlackBerry support was announced in June 2010, and has been in beta since April 2013. Tizen support was also added in April 2013 with the 3.1.0 Titanium Studio and SDK releases. The latest addition to the platform in 2016 has been Hyperloop, a technology to access native API's on iOS, Android and Windows with JavaScript.

In April 2010, Appcelerator expanded the Titanium product line with the Titanium Tablet SDK. The Titanium Tablet SDK draws heavily from the existing support for iPhone, but it also includes native support for iPad-only user interface controls such as split views and popovers. Initially the mobile SDK only supported development for iPad, but support now includes Android-based tablets as well.

In June 2011, Appcelerator released Studio and Titanium Mobile 1.7. Studio is a full open standards IDE that is derived from Aptana Studio which Appcelerator acquired in January 2011.

In June 2013, Jeff Haynie, Appcelerator's CEO, announced that the company had begun Ti.Next, a project to rewrite the Titanium SDK in Javascript for improved performance and to bring Titanium's end users, who write in Javascript, closer to the internal code.

In January 2016, Appcelerator was acquired by Axway, a global software company with more than 11,000 public- and private-sector customers in 100 countries. Since then, the Indie plans have been made free again, including native API access with Hyperloop.

Architecture
The core features of Titanium SDK include:
 * A cross-platform API for accessing native UI components such as navigation bars, menus, and dialog boxes and native device functionality including the file system, network, geolocation, accelerometer, and maps.
 * Transparent access to native functionality covered by Hyperloop and native modules.
 * MVC-based framework Alloy

All application source code gets deployed to the mobile device where it is interpreted using a JavaScript engine; Mozilla's Rhino is used on Android, BlackBerry, and Apple's JavascriptCore is used on iOS. In 2011 it was announced that a port to Google's V8 JavaScript engine is in development which, when complete, will significantly improve performance. Program loading takes longer than it does for programs developed with the native SDKs, as the interpreter and all required libraries must be loaded before interpreting the source code on the device can begin.

Titanium provides APIs for:
 * Use of hardware-specific features, such as the Android menu button
 * Use of OS-specific controls, such as the Cocoa UI controls on iOS
 * Participation in the platform ecosystem, for example using platform-appropriate notification mechanisms

Notable features

 * Since April 2018 it is possible to use Angular 6 in combination with Titanium to create mobile apps.
 * Titanium can be used with Vue.js as a framework to develop apps since May 2018.
 * Titanium supports ES6 features since SDK 6.1.0 like Classes, fat arrow functions and more.
 * Hyperloop allows the user to access native code (Java, Objective-C, Swift, C#) within JavaScript and use 3rd party libraries.
 * With Appcelerator Titanium it is possible to create native apps using JavaScript. The compiled apps use native UI components with a connection layer that is able to connect those native UI elements with your JavaScript code. The benefit is that the user will have the best user-experience on every platform since it uses the correct/native UI elements instead of creating custom elements.
 * One goal of Titanium is to reuse as much code for both platforms as possible. There is a high parity level of components and using the Alloy MVC framework makes it possible to share up to 90% of your code on both platforms.
