Vue Js Generate Unique UUID:  The randomUUID() method of the Crypto interface generates a version 4 UUID (Universally Unique Identifier) using a cryptographically secure random number generator. A UUID is a 128-bit value used to uniquely identify objects or entities. A version 4 UUID has a random value for the most significant bits and a fixed value for the version number, which is 4. The random number generator used by the method is designed to generate unpredictable and non-repeating values, making it suitable for generating secure UUIDs. This ensures that UUIDs generated using the randomUUID() method are difficult to predict or duplicate, making them useful in various security-related applications.

How can Vue JS generate a unique UUID (Universally Unique Identifier) for identifying objects or entities in a web application

This is a Vue.js application that generates a random UUID (Universally Unique Identifier) when the “Generate UUID” button is clicked. The UUID is displayed on the page using Vue.js data binding.

The data property of the Vue.js instance contains a single property, uuid, which is initially set to null.

The generateRandomUUID method is called when the button is clicked. This method uses the crypto.randomUUID() method to generate a random UUID and sets it to the uuid property of the Vue.js instance.

Overall, this code demonstrates how to use Vue.js and the crypto.randomUUID() method to generate and display a random UUID.

Vue Js Generate Unique UUId Example

<div id="app">
    <p v-if="uuid">UUID: {{ uuid }}</p>
    <button @click="generateRandomUUID">Generate UUID</button>
</div>
 <script type="module">
        const app = new Vue({
            el: "#app",
            data() {
                return {
                    uuid: null
                }
            },
            methods: {
                generateRandomUUID(){
                    this.uuid = crypto.randomUUID();
                }
            }
        });
</script>

Output of Vue Js Unique UUID

How can Vue JS generate a unique UUID using native Javascript method?

This code defines a Vue instance with a uuid data property initialized to null. It also defines a generateUUID method which uses a regular expression to replace certain characters in a string with randomly generated hexadecimal digits using the crypto.getRandomValues method. The resulting string is assigned to the uuid data property of the Vue instance.

Overall, the code generates a unique UUID using native JavaScript methods and stores it in a Vue data property for further use.

Vue Js Generate Unique UUID Using Native Javascript Method Example

<script type="module">
        const app = new Vue({
            el: "#app",
            data() {
                return {
                    uuid: null
                }
            },
            methods: {
                generateUUID() {
                    this.uuid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function (c) {
                        const r = crypto.getRandomValues(new Uint8Array(1))[0] % 16 | 0;
                        const v = c === 'x' ? r : (r & 0x3 | 0x8);
                        return v.toString(16);
                    });
                }
            }
        });
 </script>
