Vipul Patil

Could you help me understand more about your background by giving brief introduction of yourself? Okay. So hello. My name is Patel. I'm from Navinib, Maharashtra, India. I've been in IT as a software developer or engineer for more than 8 years. So with this 8 plus years of experience as senior software engineer, I bring a wealth of expertise with the realm of software development, Android, and iOS application development as well. Over the course of 8.5 years, I have sharpened my skills in front end development, specializing in Angular for 7 years, uh, React for 6 years, and utilizing both JavaScript and TypeScript for 7 years. My proficiency extends beyond web development into mobile application domain, where I have experience of 1.5 years of working with React Native. In addition to my front end progress, I boast 6 years of hands on experience in back end technologies with focus on Node. Js and an additional 2 years of experience in Java as well. This diverse skill and it builds me to contribute effectively to the entire software development life cycle. Ensuring seamless integration of printing and back end components for web application. As well as engaging responsive experiences for both Android and IS platform. Yep. That's it from my side. Thank you.

What approach do you take to manage complex state in a Redux application? Okay. The complex approaches that I do come is basically whenever we are managing complex state in Redux application, it typically involves, uh, yeah, breaking down of state into smaller, more manageable, um, more manageable, uh, pieces by making use of reducers, by making use of selectors as well as middleware. So if the the approach that you're looking for, I can come up with this. We can identify state dependencies. Uh, we can normalize state shape. We can divide state into slices. We can make use of selectors. We can leverage middleware. We can normalize updates and everything. We can do rigorous testing in order to make everything proper. Yeah. Thank you.

Explain the process and considerations when migrating a React application to use hooks instead of class components. Okay. So, basically, I have to explain the process where migration of React application to users. Okay. So whenever we are migrating a React application from class components to functional components, uh, it involves several steps, I can say. Uh, we can first, initially, we have to understand the rules. Uh, we have to familiarize, uh, use the usefulness when you are set with React tools, like use state, use effects, use context, etcetera, in order to understand that equivalent for managing the state. Then, uh, secondly, what we can do is identify class components. Uh, then thirdly, we can convert the state. By convert the state, I mean to say that we can replace class component state, which is this dot state with useStateBooks. Yeah. The, uh, then we can provide conversion of life cycle methods. Uh, along with that, we can refactor class methods as well. Sorry. Then we can handle the context. We can update the event handlers. Yeah. Thank you.

When working with the APIs, how do you handle errors and? Sorry. Sorry. Uh, okay. When working with RESTful APIs, how do you handle errors and responses in React application? Okay. Basically, when working with the RESTful APIs, we can handle errors effectively in crucial manner by maintaining the scalability and reliability. Uh, the approaches that I can come up with, We can implement the retrial logic. Uh, we can use circuit break points. We can, uh, provide rate limiting. We can, uh, handle errors gracefully. And by handling errors gracefully, what I mean to say is we can handle API errors, uh, on the client side by providing meaningful error messages to users and launching errors for debugging purposes. Uh, along with this, we can monitor the API performance. We can, uh, implement the back of strategies as well. Uh, we have to scale the infrastructure accordingly to handle this specific specific API request if they are heavily loaded. Yeah. Thank you.

What are the benefits of using virtual DOM in React, and how does it impact performance? Okay. What should DOM? Do? Basically, the virtual term that we make use of is the key concept in React. It is one of the important concepts I can say in React. Uh, as, uh, basically, it provides us several benefits and positive impacts on the performance of web application. Uh, because with the help of virtual DOM, we can efficiently handle DOM manipulation. Basically, the virtual DOM acts as a lightweight copy of an actual DOM. As whenever a state or props change in React component, React basically compares you virtual DOM with the previous version and calculates the changes to need to update the actual DOM. Yeah. Then, uh, because of this virtual dump, we do have faster rendering. We do have cross platform compatibility. Yeah. These are some of the benefits I can come up with.

What are the key considerations when setting up a React application for server side rendering? Okay. So, basically, if we are making use of server side rendering, uh, how we can implement or consider the react application. Okay? Yeah. So, basically, setting up of React application for server side rendering does require some specific factors, such as we have to ensure, uh, optimal performance. We have to check SEO and user experience as well. So the key considerations that basically I can come up with are we can choose the right framework. By right framework, I mean to say, we can select a server side rendering framework that integrates well with React. For example, Next JS, we can make use of that. Uh, then we have to make sure the environment of the server. Uh, we have to ensure that our server environment supports server side rendering with Node. Js so that we can configure our server to handle the request for both static assets and dynamic contents as well. Uh, thirdly, that I can come up with, we can provide an entry point configuration. And by entry point configuration, I mean to say is, uh, we can configure our pack or other bundler to generate a separate bundles to client side and server side. Uh, basically, this allows the server to render react components and serve it and send, uh, the initial HTML to decline. Uh, then we can define a proper application structure. Uh, we can provide, uh, we can make use of routing. Uh, we can make use of performance optimization. And since I said that we have to consider SEO as well, we have to make sure that the SEO consideration should also be taken into, uh, scenario. And most importantly, that I can come up with the consideration is the rigorous testing, the testing and debugging that we are going to do. It should happen properly.

Consider this code snippet that uses an async function in React component. There's a common bug here. Can you identify and explain what would be the issue of component and mounts before the async operation completes? Okay. I think, uh, component did mount this dot is mounted through calls responsible storage here. Data of it response to our JSON. If the sword is mounted, this dot state data. Okay. Okay. How can I explain? Basically, as per my understanding, the common bug in this code snippet that you have provided or that I'm looking at, it doesn't handle the scenario where the component unmounts before the asynchronous operation completes. If the component unmounts before the fetch data function fetch data function, I mean to say, await fetch that has been provided. Okay? Such data function resolves the promise and try to update the state using set state. Okay. It is a it will result in memory leak and potential cause of errors. Yeah. Uh, Yeah. That's all that I can currently come up with by looking at the code.

Analyzing the Redux pattern in this react snippet, what might be an issue with the way the map state to props function is implemented? Please explain your answer. Okay. Basically. Basically, if we assume that Redux is being used in this React component and map state to props has been implemented elsewhere in the application, a common issue with this map state to props could be over selecting the data. Uh, and by means of over selecting the data, I mean to say is, uh, map state props is mapping more data from Redux store to the components props that the component actually needs. This can lead to unnecessary rerenders and decrease the performance, especially if the selected data is large and frequently updated.

How would you design the state shape in Redux for complex nested data structure? Ensure efficient updates and component rerenders. Okay. Basically, if we are designing the state shape in Redux for complex nested data, uh, not data data structure, uh, it requires careful consideration. So the strategies that I can come up with is we can normalize the data, We can make use of immutable data. We can avoid deep nesting, which is very much important. We wish, should use memorization for this as well. Uh, along with this, the updates that have been provided, we should normalize it. And, uh, yeah, these are the things that I can come up with currently. Thank you.

How do you incorporate Agile scrum practices into React development workflow? Okay. Uh, basically, if we are trying to incorporate agile and scrum principles in react development workflow, uh, it should involve, uh, adapting scrum, uh, what we say, ceremonies, rules, and practices to the context of react development. Uh, basically, if we are incorporating it, I can come up with this. Uh, we can make use of scrum rules. We should define the clear rules within our React development team, which includes product owners, scrum master, the development team members, product owner. Basically, the product owner is responsible for prioritizing the product backlog while the scrum master facilitates the scrum process and removes the impediments. Okay. Team members are basically been responsible, uh, for implementing user stories and delivering increments for functionality. Okay. 2nd, product backlog. Maintain we should maintain basically a prioritized product backlog containing user stories, features, and task for react application. Uh, this specific product backlog, uh, should be continuously refined and updated based on feedback from stakeholders and changes in the requirement. 3rd and most important that I can come up with is sprint planning. Whenever we are doing sprint planning meetings at the beginning of each sprint to select user stories from the product backlog, we should define a sprint code at that particular moment. We should break down the selected user stories into smaller task, estimate the efforts required, and create a sprint backlog containing the task to be completed during the sprint. Uh, 4th, we should have daily stand ups. 5th, uh, we should have a sprint review. By sprint review, I mean to say is we should conduct sprint review meeting at end of each and every sprint to demonstrate the completed functionality to our, uh, clients, to our manager, or whoever the head would be and gather their feedback for it. Uh, Yeah. Then, uh, sprint retrospective. Retrospective. Yep. This is one of the practice that I was being I have been doing in my organization. Uh, in sprint retrospective, uh, meeting, uh, should be handled or should be performed at the end of each sprint to reflect on the team's performance, identify ideas for improvement, and make adjustment to the development process. Yeah. And, uh, the tools that I can come up with, the agile tools that I can basically can come up with is Jira, Trello. Yeah. These are some of the agile tools that we can make use of in the development.

What is your approach to optimize the back build configuration for React application? Okay. So if I want to approach I mean to say, if I want to optimize, uh, the webpack build for configuration, Uh, the approach that I can currently come up with is we can, uh, mostly, we can upgrade the webpack. We can define proper production and development configurations. Uh, we can do code splitting. We can do tree shaking. Uh, along with this, the assets. And by assets, I mean to say the image, videos, or whatever media files that we do have, we can optimize it. Uh, we can make use of minification and compression as well. Uh, Yeah. These are some of the examples that I can come up
