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...

React Developer Tools

 

Introduction:

React is a popular JavaScript library used for building user interfaces. It allows developers to build complex, interactive UIs with ease. However, as an application grows, it can become increasingly difficult to debug and optimize. This is where the React Developer Tools come in. In this blog post, we will discuss the use of the React Developer Tools and how they can help you to debug and optimize your React.js applications.

What are the React Developer Tools?

The React Developer Tools are a browser extension that allow you to inspect and debug your React.js applications. They provide a visual representation of your component tree, along with information about component props, state, and lifecycle methods.

The React Developer Tools are available as browser extensions for Chrome, Firefox, and Edge, and can be downloaded from the respective extension stores.

How to use the React Developer Tools?

Once you have installed the React Developer Tools extension, you can open it by clicking on the extension icon in your browser toolbar. This will open the React Developer Tools panel, which will show you the current state of your React.js application.

Here are some of the things you can do with the React Developer Tools:

  1. Inspect component hierarchy:

The React Developer Tools allow you to inspect the component hierarchy of your application. This can be especially useful when trying to debug complex UIs or identify performance bottlenecks.

To inspect the component hierarchy, click on the "Components" tab in the React Developer Tools panel. This will show you a tree view of your component hierarchy, along with information about each component's props, state, and lifecycle methods.

  1. View component props and state:

The React Developer Tools also allow you to view the props and state of your components. This can be useful for debugging issues related to component data.

To view a component's props and state, select the component in the component tree and click on the "Props" or "State" tab in the right-hand panel.

  1. Debug component lifecycle methods:

The React Developer Tools allow you to debug component lifecycle methods, such as componentDidMount(), componentDidUpdate(), and componentWillUnmount(). This can be useful for identifying issues related to component state management and cleanup.

To debug a component's lifecycle methods, select the component in the component tree and click on the "Profiler" tab in the right-hand panel. This will show you a timeline of the component's lifecycle methods, along with information about how long each method took to execute.

  1. Modify component props and state:

The React Developer Tools also allow you to modify a component's props and state. This can be useful for testing how your application behaves under different conditions.

To modify a component's props or state, select the component in the component tree and click on the "Props" or "State" tab in the right-hand panel. From there, you can modify the values of the component's props or state.

Conclusion:

The React Developer Tools are a powerful tool for debugging and optimizing React.js applications. They provide a visual representation of your component hierarchy, along with information about component props, state, and lifecycle methods. By using the React Developer Tools, you can identify performance bottlenecks, debug component data, and test how your application behaves under different conditions. If you're developing React.js applications, the React Developer Tools are an essential tool to have in your arsenal.

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...
