My name is Aman Kumar, and I have a 4.4 years of experience in a front end developer. I'm working as a front end developer on in with the skill set of SMS using JavaScript. Basically, working with a UI development team and somehow knowledge of front end developer as well. Like, I have a skill set of React JS, Next JS, HTML CSS, JavaScript, Terwin CSS, and get a get also. Thank you.

Some following steps when adding a new feature to a Vue. Js application that involves changing both the template HTML and corresponding REST API. Endpoints are as follows. 1st, plan the feature. Identify the functionality you want to add and outline the user stories. This will this will help you understand the scope of the changes required. Second 1, update the API. Modify the back end API to support the new functionality. This might involve creating new API endpoints, modifying existing ones, or updating the data schema. 3rd 1 is design the UI. Plan the user interface for the new feature. This includes designing the layout components and how the user will interact with the new functionality. 4th 1 is the update the view component. Make changes to the template HTML to reflect the UI design, logic to handle the new data faced from the updated API endpoints, and, lastly, test the feature. Truly test the new functionality to ensure it works as expected and integrates seamlessly with the existing applications. Thank you.

Uh first one is use HTTPS. Enable HTTPS, that is a hyper transfer hypertext transfer protocol sec secure for all communication between the Vue. Js application and the REST API. As HTTPS encrypts data in transist, making it with much more difficult for attackers to intercept and steal sensitive information. Second 1 is implement authentication. Put in place an authentication mechanism to verify the identity of user trying to access the REST API. This can be achieved with the techniques of techniques like JWT, JSON Web Tokens, or OAuth. 3rd 1 is implement authorization. Authorization determines what the user is allowed you to allowed to do after they have been authenticated. It restricts restricts access to specific API endpoints and functional functionalities based on their user's role or permissions. 4th 1 is validate user input. Sanitize and validate all user input between before sending it to the REST API. 5th 1 is keep software updated. Regularly, update your Vue. Js application libraries and the back end server framework to address secure vulnerabilities.

so here are the steps and how to handle from the input validation for data that is also being verified through a REST API in Vue.js first client-side validation we use built-in html validation attributes html offers built-in validation attributes like required minimum length max length pattern and email that you can directly add to your form elements we use Vue.js data validation libraries libraries like Vvalidate or Vvalidate offer a more robust solution for client-side validation second one is server-side validation API validation even after client-side validation it's a crucial to perform validates on the server-side as well this ensures that malicious users cannot bypass client-side checks and submit invalid data the server should validate all incoming data from the Vue.js application before processing it third asynchronous validation we use async await or promises asynchronous validation involves checking the validity of user input against the REST API in real time you can use async await or promises to handle asynchronous calls to the API and display validation message to the user as they type thank you

Discuss how to ensure that the UGS We'll use this maintain state consistency across different routes when fetching data from a REST API. These are some approaches we can take. Vuex tool. It utilizes a state management library like Vuex for centralizing management of application state. This is particularly useful for complex SPAs, where multiple components require access to the same data fetched from the REST API. Vuex provides a single source of truth for your applications data and streamlines data flow across roots. Second 1 is root guard root guards. It employ route guards in a view router to control navigation and ensure data is available before a route route is rendered. 3rd, route meta. Make sure make use of route meta information in Vue router to specify data requirements for each routes. 3rd next 1 is component catching. Implement component catching techniques to store and reuse component states across roots.

Here are some popular strategies to achieve this. Achieve the unit test for Vue. Js components effectively mock, REST API, and Raxons. First1 is using a mocking library. Library likes Axios mock adapter or CNN. Leverages libraries like Axios mock adapter or CNN to simulate API responses. Second 1, mocks with testing frameworks. Viewtest, Utils, or Jest utilize mocking functionalities provided by testing frameworks um Creating spies creating spies to mimic the behavior of the functions responsible for making API calls. Thank

Sure. Based on the code snippet, shows a potential issue that could that could prevent the data fetched from the API slash API slash API slash items from being displayed as expected on the Vue. Js component. The problem lies in how the asynchronous asynchronous operation fetch API items dot then response is handled within the mounted life cycle hook. Here's a breakdown of the potential issue. Uh, asynchronous asynchronize nature of fetch. The fetch function is asynchronous, meaning it returns a promise that resolves with the response data at same some point in the future. Mounted hook timing. The mounted hook is invoked after the component has been fully rendered in the browser in browser's DOM. Initial rendering with empty data because fetch is asynchronous by the time for mounted hook executes and sets the this dot item's data property. The component already been rendered with an empty item array since the data hasn't been

Sure. Which is about good practices for creating custom events in Vue. Js that synchronize with updates from a REST API. Here are some steps to follow. 1st, define a clear event name. Choose a descriptive event name that clearly indicates the purpose of the event. Like example, we have item updated. Emit the event from the component. Within the component that fetches, fits, or updates data from the REST API. Emit the custom event when the data changes. Use the dollar emit method passing the relevant data as an argument of the event. 3rd, listen for the event in parent component. In the parent component or any other component that needs to be notified about database. Listen for the not listen for the emitted value. Uh, emitted event value during using the v hyphen on directive. It provides a callback function that will execute it when the event is triggered 4th, pass necessary data. We ensure that the emitted event includes all the necessary data about the update. This allows the listener to perform the required actions based on the changes.
