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...

Git Merge Command

Git Merge Command


Git is a powerful version control system that allows developers to collaborate and manage changes to their codebase. One of the most commonly used Git commands is git merge, which allows you to merge changes from one branch into another. In this blog post, we will go over how to use git merge and why it is useful.

Git Merge Command

The git merge command is used to combine changes from one branch into another. This is typically done when you have two branches that contain changes you want to merge together. When you run the git merge command, Git will create a new commit that contains the changes from both branches.

How to Use Git Merge

To use git merge, first, switch to the branch you want to merge changes into. Then, run the command git merge followed by the name of the branch you want to merge. For example:

git checkout master git merge feature-branch

In this example, we are switching to the master branch and merging the changes from the feature-branch. Git will create a new commit that contains the changes from both branches.

If there are conflicts between the changes made in both branches, Git will pause the merge process and ask you to resolve the conflicts manually. Once the conflicts are resolved, you can continue with the merge process by running the command git merge --continue.

Why is Git Merge Useful?

Git merge is useful in a number of scenarios. For example:

  1. Collaborating with others: If you are working on a team, each team member can work on their own branch and merge changes into the main branch when they are ready. This allows everyone to work independently without stepping on each other's toes.

  2. Managing features: If you are working on a new feature, you can create a separate branch for that feature and merge it into the main branch when it is complete. This allows you to manage your features separately and keep the main branch stable.

  3. Rolling back changes: If you need to roll back changes made to the codebase, you can do so by reverting the merge commit. This allows you to undo changes made to the codebase without losing any other changes that may have been made.

In conclusion, git merge is a powerful Git command that allows you to combine changes from one branch into another. This is useful in a number of scenarios, such as collaborating with others, managing features, and rolling back changes. By mastering git merge, you can become a more efficient and effective developer.

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

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...
