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 checkout command

 

Git is a powerful tool for version control and collaboration in software development. One of the most useful commands in Git is git checkout. In this blog post, we'll explore what the git checkout command does, how to use it effectively, and some best practices to keep in mind.

Understanding Git Checkout

The git checkout command is used to switch between different branches in a Git repository. It can also be used to switch between different commits or tags. Here's an example of using git checkout to switch between branches:

$ git checkout branch-name

This command will switch the current branch to branch-name. If the branch doesn't exist, Git will create a new branch with that name.

Using Git Checkout Effectively

Here are some tips for using the git checkout command effectively:

1. Use It to Switch Branches

Use the git checkout command to switch between different branches in your repository. This can be useful when you're working on multiple features or versions of your codebase.

2. Use It to Switch Commits

Use the git checkout command to switch between different commits in your repository. This can be useful when you need to view or test an older version of your code.

3. Use It to Create a New Branch

Use the git checkout command with the -b flag to create a new branch and switch to it in one command:

$ git checkout -b new-branch

This command will create a new branch called new-branch and switch to it.

4. Use It to Discard Changes

Use the git checkout command with the -- flag to discard changes to a file:

$ git checkout -- file-name

This command will discard any changes to file-name since the last commit.

Best Practices for Using Git Checkout

Here are some best practices to keep in mind when using the git checkout command:

1. Keep Your Branches Separate

Use Git branches to separate different parts of your work. This will make it easier to keep track of changes, avoid conflicts, and collaborate with other developers.

2. Use Descriptive Branch Names

Use descriptive branch names that make it clear what the branch is for. This will make it easier to understand your repository's history and collaborate with other developers.

3. Avoid Checking Out Specific Commits in a Shared Repository

Avoid checking out specific commits in a shared repository. This can cause conflicts with other developers who are also working on the repository.

4. Commit Changes Before Switching Branches

Commit your changes before switching branches. This will ensure that your changes are saved and won't be lost when you switch branches.

Conclusion

The git checkout command is a powerful tool for managing branches and commits in a Git repository. By using it effectively and following best practices like keeping your branches separate, using descriptive branch names, and committing changes before switching branches, you can keep your repository organized and collaborate effectively with other developers.

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...
