Proxy Layer Structure for Applications with Anonymous Users

Overview

Security should be top-of-mind when building applications. You never want to leave data susceptible to interception or manipulation. This is even more true when creating an application for use by anonymous users. A Proxy Layer Structure for anonymous users can help.

What is the Proxy Layer Structure?

The Proxy Layer Structure takes an application and switches it to the server-side. After that, actions performed by your application won't show in the underlying code.

Say you have a module that collects a user's name, address, phone number, and email address. You then want to validate the data and create a submission for storage. A Proxy Layer Structure does this outside of your application's code.

The Proxy Layer Structure contains at least 4 modules. You may add more depending on what actions you'd like to perform. For this use case, you'll create 6 modules:

Module	Description
Browser	This is the user-facing part of your application. This is the module your end-user interacts with, whether they fill out an application or upload files. As an example use case, you'll build an application requesting an end-user’s name, address, phone number, and email.
Proxy	This module switches your application from the user-facing application to the server-side. Think of this as a curtain between your end-user and your application’s inner-workings.
Master	This is the powerhouse of your application. Here, you’ll orchestrate the actions you’d like to perform. Actions can include validating data, creating user submissions, or sending emails. The Master Module connects to each action and transmits the needed data. For this use case, you'll set up actions to validate data and create submissions from data.
Validate	For this use case, this module validates your end-user's data from the Browser Module.
Create	For our use case, this is where your end-user’s data becomes a submission.
Schema	This is the end-point of your application where the submission stores after validation.

What You'll Learn

In this article, you'll learn how to create a Proxy Layer Structure from scratch.

These instructions assume you have a new workspace open, saved, and with a title.

Set Up the Browser Module

This is the only module your end-user ever sees. Here, they'll input their data. But, if their entries don't match your requirements, they won't be able to submit. Instead, they'll see an error asking them to update their entries before submitting. Let's get started.

To set up the Browser Module, you’ll need the following:

• 1 Panel component
• 1 Columns component
• 3 Text Field components
• 1 Address component
• 1 Phone Number component
• 1 Email component
• 1 Button component
• 1 Plug-In component
• 2 Hidden components
• 1 Decisions component
• 2 HTML Element components

Here's how your Browser Module will look in the Module Builder:

Set Up the Schema Module

From the Creation Module, your user submissions store in your Schema Module. The Schema Module only serves as storage and doesn't take any actions.

The Schema Module components mirror the data-entry fields from your Browser Module. You’ll apply the same requirements in the Schema Module as you did in the Browser Module. But the structure here doesn't matter.

To set up the Schema Module, you’ll need 6 Hidden components.

Here's how your Schema Module will look in the Module Builder:

Your Schema Module works on the server-side, so your end-users will never see it in Express View.

Create the Module

Now, let's add another module to your application.

1.

In the application view of your workspace, create a new module from scratch.

2.

Enter a Module Name that contains Schema Module.

Link the Schema Module to the Creation Module

Next, you'll link your Schema Module back to the Creation Module you created in the previous section.

1.

In your Creation Module, hover over the pluginSaveSubmission Plug-In component.

2.

Using the toolbar, click the (Settings) button.

3.

In the Data Source URL, replace {moduleId} with the module ID of your Schema Module.

4.

Click Save.

5.

Save your module.

You now have a Schema Module that stores end-user submissions. You can use this Schema Module to populate a dashboard to view end-user submissions.

You can find the completed Schema Module for this use case here: https://training.unqork.io/#/form/5ebd7fb0ce23f0020fbf91d5/edit.

Summary

You now have a series of 6 modules that form a Proxy Layer Structure. The structure starts in the Browser Module where your end-user submits their information. The data then passes through the rest of the data flow, hiding it from any code. All the end-user sees after clicking Submit is a Success or an Error message.
