Basic Usage

The Zeppelin server communicates with interpreters through the use of Thrift. Apache Zeppelin on Cloudera Data Platform supports the following interpreters: JDBC (supports Hive, Phoenix) OS Shell. Livy (supports Spark, Spark SQL, PySpark, PySpark3, and SparkR) AngularJS. Zeplin CLI Angular Plugin uses a fork of Compodoc to analyze and collect information from Angular components. Zeplin is a connected workspace where you can share, organize and collaborate on designs — built with developers in mind. Storybook addon that embeds Zeplin resources such as screens and components in the addon panel for better design-development workflow. Demo Requirements. Storybook@=5.0.0; This addon should work with any framework. If you find a case that.

In addition to the backend Angular API to handle Angular objects binding, Apache Zeppelin also exposes a simple AngularJS z object on the front-end side to expose the same capabilities.This z object is accessible in the Angular isolated scope for each paragraph.

Bind / Unbind Variables

Through the z, you can bind / unbind variables to AngularJS view.Bind a value to an angular object and a mandatory target paragraph:

Unbind/remove a value from angular object and a mandatory target paragraph:

The signature for the z.angularBind() / z.angularUnbind() functions are:

All the parameters are mandatory.

Run Paragraph

You can also trigger paragraph execution by calling z.runParagraph() function passing the appropriate paragraphId:


Overriding dynamic form with Angular Object

Angular

The front-end Angular Interaction API has been designed to offer richer form capabilities and variable binding. With the existing Dynamic Form system you can already create input text, select and checkbox forms but the choice is rather limited and the look & feel cannot be changed.

The idea is to create a custom form using plain HTML/AngularJS code and bind actions on this form to push/remove Angular variables to targeted paragraphs using this new API.

Consequently if you use the Dynamic Form syntax in a paragraph and there is a bound Angular object having the same name as the ${formName}, the Angular object will have higher priority and the Dynamic Form will not be displayed. Example:

How does the front-end AngularJS API compares to the backend Angular API? Below is a comparison matrix for both APIs:

Both APIs are pretty similar, except for value watching where it is done naturally by AngularJS internals on the front-end and by user custom watcher functions in the back-end.

There is also a slight difference in term of scope. Front-end API limits the Angular object binding to a paragraph scope whereas back-end API allows you to bind an Angular object at the global or note scope. This restriction has been designed purposely to avoid Angular object leaks and scope pollution.
