Understanding and Implementing Schemas in Python Introduction In the world of programming, particularly in the context of data management and validation, schemas play a vital role. A schema is essentially a blueprint or a predefined structure that defines the expected format, data types, and constraints for a given data entity. In this blog, we will delve into the concept of schemas in Python, exploring what they are, why they are important, and how you can implement them in your projects. What is a Schema? A schema serves as a contract between different components of a system, ensuring that data is consistent, valid, and well-structured. It defines the rules for how data should be organized, what fields it should contain, and what types of values those fields can hold. In essence, a schema acts as a set of rules that data must adhere to in order to be considered valid. Why Are Schemas Important? Data Validation: Schemas provide a way to validate incoming data.

Next.js

 

Next.js is a popular open-source framework built on top of React.js that allows developers to create server-rendered React applications with ease. It was first introduced in 2016 by the development team at Zeit, and since then, it has gained a lot of popularity in the web development community. In this blog, we will explore what Next.js is, why it's gaining popularity, and how it can be used to build fast, scalable, and modern web applications.

What is Next.js?

Next.js is a React framework that provides a set of tools and features for building server-rendered React applications. It is based on the principles of simplicity, performance, and scalability, making it an excellent choice for building large-scale web applications.

One of the main benefits of using Next.js is its ability to handle server-side rendering out of the box. Server-side rendering allows the application to render on the server and send the pre-rendered HTML to the client, which results in faster page loads and better SEO performance. Next.js also supports client-side rendering and hybrid rendering, which allows developers to choose the rendering method that suits their application's needs.

Why is Next.js gaining popularity?

Next.js is gaining popularity among developers for several reasons. Firstly, it simplifies the process of building server-rendered React applications by providing a set of conventions and tools. This reduces the time and effort required to set up a new project and get it running.

Secondly, Next.js provides excellent performance out of the box. Its server-side rendering capabilities result in faster page loads, and its automatic code splitting feature ensures that only the necessary code is loaded on each page, resulting in smaller bundle sizes and faster load times.

Thirdly, Next.js has excellent support for modern web technologies such as CSS-in-JS, TypeScript, and GraphQL. It also supports serverless functions, making it easier to build and deploy serverless applications.

How to use Next.js to build React applications?

Getting started with Next.js is straightforward. Here are the basic steps you need to follow:

Step 1: Create a new Next.js project

To create a new Next.js project, you can use the create-next-app command-line tool, which will set up a new project with all the necessary dependencies and configuration files.

npx create-next-app my-app

Step 2: Create your first page

Next.js uses a file-based routing system, which means that each file in the pages directory represents a route in your application. To create a new page, you can create a new file in the pages directory with the appropriate file name.

For example, to create a new home page, you can create a new file called index.js in the pages directory and add the following code:

function Home() { return <div>Welcome to my app!</div> } export default Home

Step 3: Start the development server

To start the development server, you can run the following command:

npm run dev

This will start the Next.js development server, which will watch for changes in your code and automatically reload the page.

Step 4: Build and deploy your application

Once you have finished building your application, you can build it using the following command:

npm run build

This will generate an optimized production build of your application. You can then deploy this build to a hosting provider of your choice.

Conclusion

Next.js is a powerful framework for building server-rendered React applications. Its simplicity, performance, and scalability make it an excellent choice for building modern web applications. If you're looking to build a fast, scalable, and modern web application, Next.js is definitely worth considering.


Happy Learning!! Happy Coding!!

How to implement error boundaries in React Js

-
Error boundaries in React Js In this post, we will learn about "Error Boundaries in React Js". First of all, why we required Error Boundaries? This is the first question comes in my mind, as before React 16, we don't have any mechanism to catch error inside components and because of which whole app in broken state on next renders. No ways to handle these errors in React Components, nor it gives any methods to recover from them. React 16 introduces a new concept to handle such errors by using the error boundaries. So now, if any error found in a part of the UI, it does not break the whole application. According to official document of React Js, There are following few areas in application, where error boundaries are not suitable solution. a) Event handlers b) Asynchronous code (e.g., setTimeout) c) Server-side rendering d) Errors are thrown in the error boundary itself  For complex application which contains multiple components, we can declare multiple error boundaries to ...

Pass data from child component to its parent component in React Js In this post, we will learn about how to pass data from child component to its parent component in React js. We need to do following steps to pass/send data from child component to parent component: a) In the parent component, create a callback function. This callback function is useful to retrieve the data from the child component. b) Pass the callback function to the child as a props from the parent component. c) The child component calls the parent callback function using props and sends the data to the parent component. Send data from child component to its parent component Sample Code: A) index.js import   React   from   "react" ; import   ReactDOM   from   "react-dom" ; import   App   from   "./App" ; ReactDOM . render ( < App   /> ,  document . getElementById ( "root" )); B) App.js import   React , {  useState  }  from   're...

How to fetch data using Axios Http Get Request in React Js?

How to fetch data using  Axios - Http Get Request in React Js? In one of my previous post, I had explained all about Fetch() method to retrieve data from api server. In this post, I am going to demystify how to achieve same thing using axios. Axios has many advantages over fetch() method. 1) Axios has the ability to intercept HTTP request. 2) With axios.all() method, you can make simultaneous requests, simply send an array of request to this method, then use axios.spread() method to assign the properties of the response array to separate varialbes. 3) Axios automatically stringifies the data when sending requests, as in fetch() method, you would have to do it manually. 4) You can set response timeout. 5) Support backward compatibility, this is because it uses XMLhttprequest under the hood.  Fetch User Data Using Axios - Get Request Installation: npm install axios or yarn add axios Sample Code: A) index.js import   React   from   "react" ; import   ReactDOM...

How to fetch data from an API using fetch() method in React Js? Now a day, we can't imagine web application without API so one of the basic requirement of any web application is to communicate with servers through HTTP protocol. This can be easily done using Fetch and Axios .  In this post, we are mainly focusing on Fetch. The Fetch API provides a fetch() method defined on the window object. The fetch method has one mandatory argument i.e., URL of the resource to be fetched. This method returns promise object that can be used to retrieve response of the request.  There are following limitations of Fetch API: a) Fetch does not allows cancelling request and request timeout. b) Fetch does not provide a way to intercept HTTP requests. c) Fetch has no url in request object. d) No installation is required. e) Fetch does not have XSRF protection. f) Fetch uses the body property. g) Fetch is a two step process when handling JSON data, first - to make actual request. second - to call j...
