Jaggery is a framework to write webapps and HTTP-focused web services for all aspects of the application: front-end, communication, Server-side logic and persistence in pure Javascript. One of the intents of this framework is to reduce the gap between writing web apps and web services.As a pure Javascript server-side scripting engine, Jaggery combines all the strengths of Javascript with flexibility and freedom at both the development and deployment stages. Most JavaScript webapp development mechanisms restrict developers to a framework-specific structure or patterns, which demand an additional learning curve. By contrast, with Jaggery, any developers who are versed in Javascript have everything they need to get going.

Why do we need another server-side js toolkit
Right now, when writing a web app we need to walk through multiple layers of technology HTML(5)/JS, PHP/Ruby/Java, ORM(SQL)
Information captured at the client need to be transformed at each layer JSON/CSV/XML
Its not straightforward to build a natively REST/JSON app
Developing an API coupled to the app is a nightmare
What is Jaggery
A completely Javascript way of writing all parts of the Web applications and services Eliminates the mismatches across different layers
Closes the gap between Web apps from Web services by allowing one to create both applications and APIs at the same time.
What jaggery offers for multi-tier web app development
A vanilla platformNo heavy frameworksNo restrictionsOnly a set of APIsSmooth & easy deploymentEnterprise grade runtime
What it has, as of now
A module architectureThe runtime augments the features of a web serverIt talks smoothly in JSONCan handle URL patternsCan talk to databasesA Shell that can execute the jaggery scriptsIts a new platform, we believe everybody will start building
cool things
How to make things workExtract jaggery-1.0.0-SNAPSHOT_M5.zip to a directory you
prefer. lets call it JAGGERY_HOME
Navigate to {JAGGERY_HOME}/bin directory which contains all the Jaggery execution scripts.
Run sh {JAGGERY_HOME}/bin/server.sh ({JAGGERY_HOME}/bin/server.bat in windows) command to start the server
Point the browser URL to http://localhost:9763/taskmaster
The famous "Hello World" in Jaggery
Create a directory called helloapp at {JAGGERY_HOME}/apps/
Create a jaggery file helloworld.jag inside the helloapp directory and add the following code snippet
Thats it! now point to {http://localhost:9443/helloapp/helloworld.jag}
The APIhttp://jaggeryjs.org/documentation.jag
The extensibility
Jaggery can be extended using modulesYeah ! go on write some
You can import any script which is written for commonjs as a jaggery module
If nothing for the rescue, you can expose even a JAVA library as a module for Jaggery
and you can do this !
It's awesome coz, it's just javascript & JSON end to end
If you simply want to send some JSON to the client
It's built to write RESTy apps Match URLs at runtime
Design URLs at development time
It's modular
Its extensible via modulesEven the core is written in modules and bound with
configuration
It's completely open-source, under Apache 2.0
