In web development, generating unique IDs is a common requirement for various purposes, such as tracking user data, creating unique URLs, or managing database records. In this blog post, we'll explore how to generate unique IDs using Wix and the UUID library. We'll provide a step-by-step explanation of the code and discuss its implementation.

While Wix provides many built-in features, there are times when you may need to incorporate additional functionality into your Wix site. In this blog post, we'll explore how to install and use the UUID NPM package in Wix to generate unique identifiers for various purposes.

Step 1: Turn on Developer Mode

Before we dive into installing and using the UUID package, ensure that you have your developer mode enabled.

Step 2: Install UUID NPM Package

Search for UUID and install

Step 3: Import the UUID to your page

To incorporate external libraries or packages, Wix provides a built-in development environment called Wix Code. Here's how you can add the code for generating UUIDs to your website page.

const uuid = require('uuid');

Step 4: Use set() object to make sure that the IDs are unique. The set() object will store the generate IDs and makes sure that it is not replicated in the future, even though the chances of that happening are 0 to none.

let uuidSet = new Set();

 while (uuidSet.has(generatedID)) {
      generatedID = uuid.v4();
 }

 uuidSet.add(generatedID)

Step 5: Create a function that returns the Unique ID

const uuid = require('uuid');

    let uuidSet = new Set();

    function generatedUniqueID() {

        let generatedID = uuid.v4();

        while (uuidSet.has(generatedID)) {
            generatedID = uuid.v4();
        }
        uuidSet.add(generatedID)

        return generatedID

    }

That's it.

Each time you use this function, it generates a unique ID.

generatedUniqueID()
