Lianja for JavaScript Developers

If you are a JavaScript developer and you want to create great looking database Apps then you will feel right at home with Lianja.

There is no need to learn a new language -- Lianja has JavaScript embedded inside it as well as LianjaScript, Python and PHP. Yes, that's right, all these scripting languages are embedded inside Lianja and they are all fully integrated so that code can be written in any of these scripting languages.

Lianja takes a radically different view of app development providing a high level of abstraction for visually designing, developing and deploying multi-client-device business apps on whatever operating system you choose; Windows, Mac OS X, Linux x86 and Linux x64.

When we set out to develop Lianja we made a conscious decision to architect and build a product that embraced dynamic scripting languages, hence the support for Visual FoxPro scripting, PHP, Python and JavaScript.

Lianja is also cross-platform; Windows, Mac, Linux (and others), and it allows you to build data-centric apps that can connect to any data source; MSSQL, MySQL, PostgreSQL, Oracle (and others), but also very importantly it enables both professional developers and domain-experts (people who know everything about their business but are not programmers) to be able to build compelling Desktop, Web and Mobile Apps. 

Lianja has a feature complete set of UI classes so you can build modern looking Apps. All of the UI classes can be skinned with CSS to improve their visual appearance without having to hard code this in.

The database engine in Lianja is full 64-bit with huge file support with no practical restriction on the size of database tables.

One of  the unique features of Lianja is that it has a complete cross-platform web browser component built-in (based on Webkit) as well as a built-in JavaScript server page processing engine. Server pages can be written in JavaScript and embedded into your Lianja Apps (.jssp files). There is no need to install or configure anything to obtain this functionality.

When you install the Lianja App Builder you will find it includes jquery, jquery mobile, backbone, bootstrap and knockout.js libraries all ready for you to use when you need to build your own Lianja WebViewWidgets in JavaScript and integrate them into your Lianja Apps.

Building database Apps in Lianja using JavaScript is simple and straightforward. We truly believe there is no faster way to build Apps than with Lianja. With its unique meta-framework JavaScript developers can build compelling Desktop, Web and Mobile business Apps using the Lianja App Builder with minimum coding being required. 

Lianja Cloud Server provides complete support for building end-to-end Business Apps in JavaScript. Lianja Cloud Server embeds the Google developed V8 JavaScript engine to provide built-in support for JavaScript Server Pages (.jssp pages) which offer similar functionality to PHP server side pages. There is no faster way for JavaScript developers to build stunning database Apps in the language they already know and love. For an introduction to JavaScript Server Pages read the Introduction to Lianja Cloud Server article.

Additionally, Lianja also has a complete database server -- Lianja SQL Server -- that runs on Windows and Linux. Lianja SQL Server is a true database server just like MySQL or MSSQL -- the big difference being that you can write stored procedures and triggers all in Visual FoxPro.

The Lianja SQL Server is built into the Lianja Cloud Server with complete JavaScript integration.
