Stateful EJS Template

This simple template demonstrates the use of EJS in a stateful environment. EJS stands for Embedded JavaScript templating. For more information, visit http://ejs.co.

Statefulness

This app uses a stateful top-down paradigm, meaning that when a screen is displayed, the Node.js code is paused to wait for the user's input. In a stateful program, EJS screens can intermingle with Rich Display screens built using the Visual Designer tool.

Strongly typed fields

This app uses strongly typed fields and the pjs.define() API.

At its core, JavaScript is a loosely typed language, which means you do not have to declare the data types of variables explicitly. JavaScript variables assume a data type based on the content that is placed in them.

However, for business applications, being able to explicitly specify a data type can be extremely useful. For example, you may want to strongly type an amount field, so that it can only hold numeric data with a specific precision (length and decimal positions). In a business application, putting character data into an amount field should raise an exception.

API

  • pjs.define() - Define a strongly typed field
  • pjs.display() - Display content from an EJS template and wait for the user to respond
