what is JSON Web Tokens (jwt)
Tags: oauth, jwt, authjs, api
Published: 2024-02-14 06:40:42

## What is Authentication

The set of protocols an application uses to confirm user identity is authentication

## Token authentication
Token authentication was developed to solve problems that server-side session IDs didn’t, and couldn’t. Just like traditional authentication,

## What is a JWT?

JWT stands for JSON Web Token
It is a standard for representing claims securely between two parties

A JWT consists of three parts: a header, a payload, and a signature. 
These parts are encoded into a single string, which can be easily transmitted between systems
Jwt looks something like this:
`eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ`



![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ije1qixiifge3ymfr2r1.jpeg)
### Let's break down each part:

1. Header: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9
   This part typically contains two fields: the type of the token (JWT in this case) and the signing algorithm being used (HS256 in this case, which is HMAC SHA-256).


2. Payload: eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ

The payload contains the claims. 
Claims are statements about an entity (typically, the user) and additional data.

 There are three standard claims: "iss" (issuer), "exp" (expiration time), and "sub" (subject). The payload in your token appears to have these claims:

`"sub": "1234567890"
"name": "John Doe"
"iat": 1516239022`

3. Signature: SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c  

To ensure the integrity of the token, a digital signature is generated using the header, payload, a secret key (known only to the server), and a specific algorithm defined in the header

## How it works:
When a user wants to access a protected resource they need to be authenticated. Here’s how the process works:

- Authentication (Login): The user provides their credentials (e.g., username and password) to the server

- Token Creation: The server verifies the credentials and generates a JWT, which includes the user’s identity and any additional necessary information (e.g., user role, permissions).

- Token Transmission: Once created, the JWT is sent to the client as a response to a successful login request. 
JWT tokens should be stored in an HttpOnly cookie, which is a special kind of cookie that's only sent in HTTP requests to the server and is never accessible from JavaScript running in the browser.

don't store jwt in a cookie, local storage, or session storage 

- Subsequent Requests: For each subsequent request, the client includes the JWT in the request header or another secure method (e.g., Authorization header). This way, the server can identify and authenticate the user based on the JWT.

- Token Verification: Upon receiving the JWT from the client, the server verifies its integrity and authenticity by recalculating the signature using the same secret key and algorithm. If the signature matches, the server trusts the information contained within the JWT

express js
Published: 2024-02-16 08:05:32

A well-liked Node.js web application framework, Express.js is renowned for its adaptability and simplicity. Although many developers are familiar with Express.js's fundamental functionalities, there are a few lesser-known features that can improve your comprehension and utilisation of the framework:


Middleware Execution Order: To manage HTTP requests, Express.js makes use of middleware. Because middleware is performed sequentially, the order in which it is defined matters. When middleware functions are used with app.use() or similar methods, they are run in the order that they are inserted. It is important to comprehend this because the middleware order can affect the outcome.
Multiple template engines, including EJS, Pug, and Handlebars, are supported by Express by default. Nevertheless, it also comes with an integrated template engine known as express-generator, which by default use the EJS templating language. Setting up a simple project structure with views and routes may be done quickly this manner.

Express Generator is a command-line utility that aids in creating the fundamental framework of an Express application. For more complex projects, it's a helpful place to start, and developers can alter the generator's templates to suit their needs.

Shifting to Flutter to build a social media app with no experience
Tags: beginners, flutter
Published: 2024-02-16 07:20:29

**Introduction:**
Switching from Python and JavaScript to Dart and Flutter for my social media app was actually pretty fun and I learned a lot! There were a lot of challenges and stressful days but I'm glad I stuck with it.

**Embracing the Unknown:**
When I started learning Dart's syntax and Flutter's widget-based architecture, I was a bit scared at first. Shifting from Python's easy-to-read code to Dart's strict typing system was a significant change for me. But then I realized that Dart's simplicity and Flutter's expressive UI framework could actually make my coding process a lot smoother.

**The Learning Curve:**
I had to put in a lot of effort to learn Dart and Flutter. I spent hours reading documentation, asking chatGPT, and watching tutorial videos on YouTube. It was tough, but with time and practice, I got better at using Dart's features and Flutter's widgets. And can only improve with time

**Overcoming Challenges:**
Managing state in Flutter's reactive framework was a difficult challenge for me. It took some time to wrap my head around concepts like setState(), Provider, and Bloc. But, with every obstacle I overcame, I gained a deeper understanding of Flutter's state management solutions, and how they help in building scalable applications. It really mostly like react and that helped a ton since I had experience.

**The Rewards of Adaptation:**
Looking back at my journey, I realized that taking risks and trying new things has been super important for my growth. By challenging myself and doing things outside of my comfort zone, I've learned so much about modern app development and have gained a ton of new skills. These experiences have not only helped me successfully complete my social media app project, but also made me feel more confident and resilient as a programmer.

**Conclusion:**
In just three weeks, I totally transformed my programming skills from Python and JavaScript to Dart and Flutter. It was quite a journey, but I persevered, stayed curious, and was open to new experiences. And you know what? It opened up a whole new world of possibilities in app development for me! As I look ahead to new projects, I'm excited to continue learning and growing, and applying everything I've learned to innovate and explore in the ever-changing tech landscape.
Best Practices and Strategies: Web Application Testing
Tags: webapplicationtesting, webtesting, webapptestautomation, testingwebapplication
Published: 2024-02-16 07:34:57

Web application testing is a critical component of the software development lifecycle, ensuring that web-based systems function correctly, securely, and efficiently. To effectively manage the testing process for web applications, it's essential to implement best practices and strategies. Here's an overview of the test management process in web application testing:

**Requirements Analysis:** Begin by thoroughly analyzing the requirements of the web application. Understand the functional and non-functional requirements, user expectations, and business goals. Clear comprehension of requirements sets the foundation for designing comprehensive test cases.

**Test Planning:** Develop a detailed test plan that outlines the testing objectives, scope, timelines, resources, and risks specific to the web application. Consider factors such as browser compatibility, device compatibility, security testing, performance testing, and usability testing in your test plan.

**Test Environment Setup:** Establish a test environment that closely resembles the production environment to simulate real-world conditions accurately. Configure the necessary hardware, software, browsers, and network settings to facilitate testing. Utilize virtualization and containerization technologies to create scalable and efficient test environments.

**Test Case Design:** Design test cases that cover all functionalities, features, and use cases of the [web application](https://tenjinonline.com/web-app-testing/). Incorporate positive and negative test scenarios, edge cases, boundary conditions, and stress tests to ensure comprehensive test coverage. Leverage automation tools for repetitive and regression testing to improve efficiency.

**Test Execution:** Execute test cases systematically according to the test plan. Perform functional testing, regression testing, integration testing, security testing, [performance testing](https://yethi.in/performance-testing/), and usability testing as per the defined test scenarios. Monitor and record test results, including any defects or deviations from expected behavior.

**Defect Management:** Implement a robust defect management process to capture, track, prioritize, and resolve defects identified during testing. Use a defect tracking system to log defects, assign severity and priority levels, and communicate with developers for timely resolution. Conduct root cause analysis to identify underlying issues contributing to defects.

**Test Reporting and Metrics:** Generate test reports summarizing test execution results, defect metrics, test coverage, and other relevant information. Communicate test progress, quality status, and any risks or concerns to stakeholders regularly. Utilize metrics to assess the effectiveness of testing efforts and make data-driven decisions for process improvement.

What is research profile?
Tags: research, researchpaperwriting
Published: 2024-02-16 07:29:07

We have a wrong concept that only PhD or masters students can get them indulged to research works/ writing which is absolutely wrong. In this blog, I'm going to share every detail about crafting a research paper from first to last. Enjoy!

## What is research profile? why one should care about having a strong research profile?

This thing can be thought of 5 aspects:

- Research projects: It has very low value because doing projects and just adding it into your resume is not a big deal. Everybody has projects and they just add it to their resume. So it doesn't hold that much of value. 

- International Research Internship: It is valuable if there is tangible research outcome. 

- Papers: Having high quality journal paper. Then publishing it in conference and having patents. It has a really high value and makes really strong research profile.

## Research papers are of some kinds:

1. Journal paper with new result
2. Literature review paper
3. preprints : preprints are preliminary versions of a scientific manuscript that researchers share by posting to online platforms known as preprint servers before peer-review and publication in an academic journal.
Callback Functions in JavaScript: A Beginner’s Guide
Tags: webdev, javascript, programming, beginners
Published: 2024-02-16 07:00:43

When you start learning JavaScript, you often come across the term “callback function.” It’s a fundamental concept in JavaScript programming, but it can be a bit confusing at first. Let’s break it down in simple terms.

What is a Callback Function?

In JavaScript, a callback function is a function that is passed as an argument to another function and is executed after some operation has been completed. Think of it as a recipe: you have the main function (the chef) that performs some task, and the callback function (the helper) that is called once the task is done.

Example of a Callback Function

Let’s consider a scenario where you want to load some data from a server and then display it on a webpage. You would use a callback function to handle the data once it’s been loaded. Here’s a simple example:

`function loadData(callback) {
  // Simulate loading data from a server
  setTimeout(() => {
    const data = { message: "Hello, world!" };
    callback(data);
  }, 2000);
}

function displayData(data) {
  console.log(data.message);
}

loadData(displayData);`
