Custom Code

In the Profound.js low-code environment, much of the functionality can be created without writing any code.

However, if you need to add functionality that is more advanced than what is provided by the plugins, any step can then be written as server-side or client-side JavaScript code. You can mix Code-based steps with No-Code steps at a granular level, without having to work with the entire application as code.

Writing Server-side Code

To write Node.js (server-side JavaScript) code, select the “Write Custom Node.js Code” plugin under the “Custom” category when adding a step.

You can use any JavaScript code, including direct calls to any of the pjs API.

If you need to write code for the start of a condition or loop that will encompass other steps, select the “Node.js Loop/Condition Partial”.

As you’re writing code, you can insert references from the low-code environment by clicking on the Insert Dynamic Data icon.

Work variables can be referred to directly by name in your code.

Screen fields can be referenced using the following syntax:

screenName["fieldName"]

Global properties can be accessed by using the following format:

globals["property name"]

Writing Client-side Code

To write client-side JavaScript code, select the “Write Client-side Code” plugin under the “Client-side” category when adding a step. If you need to write client-side code for the start of a condition or loop that will encompass other client-side steps, select the “Client-side Loop/Condition Partial”.

If the entire routine is custom code, it may be easier to just write the code directly in the widget event property, rather than creating a routine.

Converting Existing Steps to Code

You can convert any existing low-code step to code by clicking the JS icon on the action dialog.

convert-step

You can then customize the code and save your changes.

Code Analysis

The Profound.js low-code environment will analyze the code you write in order to provide future suggestions for work variables and global properties. Only outer-level declarations will be analyzed. For example, if you write this line of code:

var maxRecords = 10;

Profound.js may start suggesting maxRecords as a value for answers to other low-code plugins.

Viewing the Entire Program as Code

You can view or export the auto-generated code for the entire application from the Logic tab by clicking on the corresponding toolbar icon.

view-nodejs

The application will then be translated to Node.js.

This can be useful in gaining an understanding of how low-code applications are structured and will help you in writing your custom routine steps.
