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...

How to integrate Azure Application Insights with logging in a Python

 

To integrate Azure Application Insights with logging in a Python application, you can use the applicationinsights package. Here's an example of how to configure logging with Application Insights in Python:

  1. Install the applicationinsights package:
pip install applicationinsights

  1. Import the necessary modules:
import logging from applicationinsights import TelemetryClient from applicationinsights.logging import LoggingHandler

  1. Configure the Application Insights instrumentation key:
INSTRUMENTATION_KEY = 'your-instrumentation-key'

  1. Create a TelemetryClient instance:
tc = TelemetryClient(INSTRUMENTATION_KEY)

  1. Set up a LoggingHandler to capture and send logs to Application Insights:
logging_handler = LoggingHandler(tc)

  1. Configure the root logger to use the LoggingHandler:
logging.getLogger().addHandler(logging_handler)

  1. Log events using the Python logging module:
# Log an informational message logging.info('This is an informational message') # Log a warning message logging.warning('This is a warning message') # Log an error message logging.error('This is an error message')

With the above setup, any logs generated by your application will be sent to Application Insights. You can view these logs, along with other telemetry data, in the Azure portal.

Make sure to replace 'your-instrumentation-key' in Step 3 with your actual Application Insights instrumentation key, which you can obtain from the Azure portal.

Note: The applicationinsights package also provides additional functionalities for tracking custom events, metrics, and exceptions. You can explore the package's documentation for more advanced usage scenarios.

Remember to handle any exceptions or errors that may occur during the logging process to ensure the smooth functioning of your application.


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

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...
