Understanding and Implementing Schemas in Python

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. When data is received o

Use of Facade Design Pattern in React Js 


ReactJS is a popular JavaScript library for building user interfaces. It's widely used in web development because of its reusability and easy-to-use features. One of the design patterns that can be used with ReactJS is the Facade Design Pattern. In this blog, we'll discuss what the Facade Design Pattern is and how it can be implemented in ReactJS.

What is the Facade Design Pattern?

The Facade Design Pattern is a structural design pattern that provides a simplified interface to a complex system. It's used to hide the complexity of a system and provide a simple and easy-to-use interface to the client. The main idea behind the Facade pattern is to provide a single point of entry to a complex system, thus making it easier to use.

The Facade pattern is particularly useful in situations where there are multiple layers of complexity in a system. In such cases, the Facade pattern can be used to provide a simple and easy-to-use interface that hides the complexity of the system.

How to implement the Facade Design Pattern in ReactJS

In ReactJS, the Facade pattern can be implemented using a component that provides a simple and easy-to-use interface to a complex system. The component can be used as a wrapper around the complex system, thus hiding the complexity of the system and providing a simplified interface to the client.

Let's take an example of how the Facade pattern can be implemented in ReactJS. Suppose we have a complex system that consists of multiple components. We can create a Facade component that provides a simplified interface to the client. The Facade component can then be used as a wrapper around the complex system, thus hiding the complexity of the system and providing a simplified interface to the client.

Here's an example of how the Facade pattern can be implemented in ReactJS:

import React from 'react'; import ComplexSystem from './ComplexSystem'; const Facade = () => { const [data, setData] = React.useState([]); const fetchData = async () => { const data = await ComplexSystem.fetchData(); setData(data); }; const sendData = (data) => { ComplexSystem.sendData(data); }; return ( <div> <button onClick={fetchData}>Fetch Data</button> <button onClick={() => sendData({ name: 'John', age: 30 })}>Send Data</button> </div> ); }; export default Facade;

In the example above, we have a Facade component that provides a simplified interface to the client. The component has two buttons that call the fetchData and sendData methods of the ComplexSystem component. The ComplexSystem component is a complex system that consists of multiple components. However, the complexity of the system is hidden from the client, and the client only interacts with the Facade component.

Conclusion

The Facade Design Pattern is a useful pattern that can be used in ReactJS to provide a simplified interface to a complex system. By using a Facade component as a wrapper around a complex system, we can hide the complexity of the system from the client and provide a simple and easy-to-use interface. This makes it easier for developers to work with complex systems and improves the overall user experience.

useNavigate and useLocation hooks - Navigating programmatically to a route. In this post, we will learn about two new hooks from react-router-dom version 6 library. 1) useNavigate - Let’s say on click of a button, If you want to perform redirection to the page, then react router provide us with a hook called as useNavigate. - useNavigate hook replaced useHistory hook, but it works same as useHistory but in addition it has good feature. - useNavigate hook is only available in react-router-dom version 6. - We can redirect to Previous and Next page with the help of useNavigate hooks.  2) useLocation - We required two library React 16.8+ and react-router-dom 5.1+ for useLocation hook. - It is a function that returns the location object that contains information about the current URL. - New location object is created, whenever the URL changed. useNavigate and useLocation hooks react router dom version 6Js and Xstate Install React Router Command npm install react-router-dom --save Sample cod

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   'react' ; import   './style.css'

How to fetch data from an API using fetch() method in React Js

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 json()

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   from   "rea
