About the SSJS for Marketing Cloud Extension

SSJS for Marketing Cloud is a VSCode extension that lets you write modern javascript syntax, and have it compile automatically into SFMC-safe SSJS code that you can directly in the editor and see immediate responses in the console.

• Write ES6 Syntax: Imports, Classes, Arrow Functions, and more;
• With cone command, your code is executed directly in your Marketing Cloud instance via a secure CloudPage proxy that you control and own;
• The results of your script are streamed directly into your VSCode terminal for immediate feedback;

This guide explains how to set it up for the first time.

Installation

Since this extension is still in alpha, it has not been published to the VSCode marketplace yet, and access is given in priority order from my waitlist.

In your email invite, you will find a link to the VSIX extension file, download the file and, in VSCode:

1. Click the Extensions menu
2. Click the three dots at the top of the extensions list and choose Install from VSIX

Setting up for the first time

To make sure only authorized users can run code in your instance, the extension uses a private CloudPage link and tokens stored in a Data Extension that you have to configure.

1. Create the SSJS_Tokens Data Extension

In the instance you want your code to run, create a data extension with the following properties:

• Name: SSJS_Tokens
• External Key: SSJS_Tokens
• Fields:
  • Token (Text, max characters 100)
  • isValid (Boolean)

2. Add a token to your DE

• Create at least one record in the DE. Generate a secure token (suggestion randomkeygen).
• Make sure to set the isValid field to true

3. Create the Code Resource

• In CloudPages, create a new Code Resource of type JSON and paste the code below:

• Save the Code Resource and Publish it. The Name and URL format do not matter here.

4. Setup the extension

Open a folder in VSCode and:

• Create a .env file in the root directory of your project folder
• Paste the following code and substitute the values for your token and cloudpage url:

Setup is done!

How to use the Extension

1. Create your TypeScript file

Now the fun part! In the same environment you created your .env file, create a .ts (TypeScript) file and write your SSJS:

2. Test Direct Execution

• Hit CMD+P or (Ctrl+P on Windows) to open the command pallete
• Search and run the command SSJS: Run Script
• If everything was setup correctly, you should see Hello from VSCode directly in the output console

3. Write modern TypeScript

In your .ts files, you can separate your code into modular files and use the modern TypeScript Syntax:

• Import
• Arrow Functions
• Classes
• … and more! (we are adding support for polyfills of modern syntax)

• run the code using the SSJS: Run Script command and get instant feedback

4. Test Local Bundling

• Use the command SSJS: Build (Bundle to Single File) ;
• Look for new folder dist/ created next to your file where the generated SSJS file is is saved;
• Use this process to build scripts you can deploy to CloudPages or Automation Studio.

Contribute and Provide Feedback

If you have any direct feedback, feel free to reach out directly to me via LinkedIn or via email at hello@lucascosta.tech. Once the beta tester pool increases, I will create a Discord server to gather feedback so watch your email for the invite.

Thank you so much for joining the waitlist and testing out the SSJS for Marketing Cloud extension and happy coding.
