Authentication and Authorization in Web Applications
Tags: webdev, beginners, node, javascript
Published: 2024-04-27 10:16:07


**Authentication**

It Provides you with who you are, like login into the website, and the website verifies the email and password.

Authentication is like showing your ID to enter a secure building. When you log in to a website or app, it checks your username and password to confirm that you are who you say you are. Once Verified, you’re granted access to your account, just like unlocking a door with a key.

**Authentication Under the Hood**

It happens on the server, the client sends the login request to the server and the server verifies it and sends a response, in that response there will be a session ID, the session ID is nothing but a unique ID stored as a cookie on your local machine, it is used for server to remember who you are, without session-ID server can’t remember, so every time you make the request the session-ID is sent along with the request to the server.

**Authorization**

Permission to do this, like users and admin, it’s role-based

Once you’re authenticated the server authorizes you

Authorization is like having different levels of access in a building. Once you’re inside, you might have permission to enter certain rooms, but some rooms are restricted for you. it’s a role-based thing, if you are the manager of the hotel, you have access to certain rooms that are restricted to the client. Similarly, in a web application, authorization determines what actions you’re allowed to take.

**Authorization Under the Hood**

It is going to send a request to the server, for example, on a website let’s say you want to delete something that you are not permitted to, when you click the button the request is sent to the server along with the session ID. The server verifies that if the user has permission to delete this if the user doesn’t have permission, it will send the response “Not permitted” or something.

Published: 2024-04-27 10:01:04

Hello guys my previous post on what technologies do big companies use brought spike in my read, likes and comments 🤠. So, here I am with 5 more companies. Let's get started ✨ 

## Minecraft 

Ok, Guys I thought the first three companies top games, so here is Minecraft. Minecraft was made in Java completely in Java. How annoying that is ! 😭 

## Roblox

The renowned game 🎮 which is loved by kids Roblox is made with Lua. Never heard of name ? Lua is a powerful, efficient, lightweight, embeddable scripting language. yep, great choice 😁 

## Twitch

Twitch is another famous app used by gamers. So, I thought, this should be in the list. Well, guys Twitch was made with Go, C/C+, Ruby/Rails, Ember js. That's a big list 

## Discord

Discord is made with one of my favourite programing languages. Javascript, yep don't troll me for this. I am an innocent person addicted to javascript 😇.

## Codepen

Codepen is widely used by developers all around, but what is it made of. Well it's made up of React, Vue and angular.

Comment 💬 your pick if you would make a mobile app, desktop app and a web app. 

I also upgraded citeal animations today guys...

How to Update Firestore Documents Within an API Route Using Next.js
Tags: javascript, nextjs, firebase, webdev
Published: 2024-04-27 10:00:34


In recent projects, the development team at [itselftools.com](https://itselftools.com) has expounded the versatility of using Next.js combined with Firebase for building robust applications. Over 30 projects later, our practices have refined. Today, we'll share a concise but practical example of updating a Firestore document directly within an API route using Next.js. This pattern proves highly effective for managing database transactions in serverless environments.

## Understanding the Code

Here's a brief look at the code snip we'll be discussing:

```javascript
// Update a Firestore document in an API Route
import { Firestore } from '@google-cloud/firestore';
const firestore = new Firestore();
export default async (req, res) => {
  const { docId, age } = req.body;
  try {
    const result = await firestore.collection('users').doc(docId).update({ age });
    res.status(200).json({ success: true, id: docId, updatedFields: { age } });
  } catch (error) {
    res.status(500).json({ error: 'Failed to update document' });
  }
};
```

### Detailed Explanation

1. **Importing Firestore**: At the very top, the Firestore class from the '@google-cloud/firestore' package is imported for interfacing with Firestore.

2. **Instantiating Firestore**: A new instance of Firestore is created immediately after import. This sets up the connection to our Firestore database.

3. **API Route Handling**: The function following the instantiation of Firestore acts as the default export of this API route. It is designed to handle a POST request, where `docId` (document identification) and `age` are expected in the request body.

4. **Update Operation**: Within the try block, `firestore.collection('users').doc(docId).update({ age })` performs the update operation. If successful, a response is sent back with status 200, indicating successful update and also relays which document and fields were updated.

5. **Error Handling**: In case of an error during the operation, the catch block captures this exception and responds with a 500 status code, signifying an internal server error.

## Conclusion

Mastering the integration of Firestore operations within Next.js functions offers a streamlined approach to handling data interactions in serverless applications. For those keen to see this functionality in action, consider visiting some of our applications: [Find Words](https://find-words.com), [OCR Free](https://ocr-free.com), and [Webcam Test](https://webcam-test.com), each merging modern web technologies and user-centric designs for enhanced online interaction.

Deploying such integrations within your projects not only minimizes server overhead but also improves response times, thereby elevating the user experience.

useState and useReducer
Tags: javascript, webdev, beginners, react
Published: 2024-04-27 09:17:35

Similarities between useState and useReducer:

Both useState and useReducer are React hooks used for managing state in functional components. They share these key points:

- State Management: They both allow you to store and update data within a component that can trigger re-renders when the state changes.

- Functional Components: They are exclusive to functional components in React, providing an alternative to the setState method in class components.

- Return Value: Both hooks return an array containing:

   - The current state value.
   -    A function to update the state (setter function for useState and dispatch function for useReducer).


When to use useState:

- Simple State: It's ideal for managing a single piece of state, especially primitive values (strings, numbers, booleans) or single objects/arrays.
- Straightforward Updates: The state updates are easy to understand and don't require complex logic or dependencies on previous state values.
- Readability: You prioritize keeping your component code concise and easy to reason about.

When to use useReducer:

- Complex State Management: You're dealing with multiple state values that are updated interdependently or require handling previous state values.
- Centralized Logic: You want to centralize state update logic in a separate reducer function to improve code maintainability and reusability.
- Advanced Patterns: You need to implement advanced state management patterns like state history or optimistic updates.
- Performance Optimization (Deep Updates): You're working with deep updates in the component tree, where useReducer can offer slight performance improvements because dispatch functions can be passed down without recreating functions on every render.

How Mobile App Analytics Can Help?
Tags: analytics, appsync, mobile, it
Published: 2024-04-27 09:14:50

Mobile app analytics provide valuable insight into app performance across multiple dimensions, including performance, usage, and marketing effectiveness. Performance analytics provide important data about application stability, speed, and potential problems such as crashes. This includes information about device models, operating systems, and network conditions that affect the user experience.
Usage analytics analyzes user behavior within an app, highlighting navigation paths, feature interactions, and areas where users encounter obstacles or experience lag. Understanding user interactions and preferences allows developers to optimize application design and improve user satisfaction. To make your app more efficient and profitable, it is recommended to use mobile analytics tools. You can learn more about these mobile analytics tools in the blog from **[AppMetrica](https://appmetrica.yandex.com/about/blog/best-analytics-tools-for-mobile-app)** Yandex.
Marketing analytics focuses on measuring the impact of marketing campaigns on app performance metrics such as ad clicks, installs, and user engagement. This data helps evaluate the return on investment (ROI) of advertising spend and optimize campaign strategies to maximize app visibility and user engagement.
Additionally, marketing analytics makes it easier to identify successful advertising channels and partners through mobile attribution, allowing publishers to effectively allocate resources and drive sustainable growth. Using comprehensive performance, usage, and marketing analytics, app developers can make data-driven decisions to improve app performance, user engagement, and overall business success.
Testing Techniques
Published: 2024-04-27 08:57:58

**Boundary Value Analysis:**
Boundary Value Analysis is based on testing the boundary values of valid and invalid partitions. The behavior at the edge of the equivalence partition is more likely to be incorrect than the behavior within the partition, so boundaries are an area where testing is likely to yield defects.

**Decision table testing:**

- Decision table technique is one of the widely used case design techniques for black box testing. 

- This is a systematic approach where various input combinations and their respective system behavior are captured in a tabular form.
- Decision table technique is appropriate for the functions that have a logical relationship between two and more than two inputs.

**Use Case Testing:**
Use case testing is a functional testing technique that helps in identifying and testing scenarios on the whole system or doing start-to-end transactions. 

**LCSAJ Testing:**

- LCSAJ testing is a white-box testing methodology used to determine the code coverage, i.e., what percentage of the code is executed with the existing test cases. 
- It helps in designing new test cases, which can increase the coverage of the code under test. Once the code coverage reaches a certain level, we can stop the testing. 
- Hence, LCSAJ methodology also helps in determining when to stop the testing of a software.

Today, I released version 2.0.0 (for React Native v0.74.0) of react-native-awesome-template, a simplified starter template for React Native. This template aims to enhance your app development experience by providing some configurations that helps you make fewer mistakes during the development process, specifically before committing or pushing to your project repository.

## Introduction

When developing a real-world application, more careful consideration is required. This becomes even more apparent when a team, comprising developers with varying levels of expertise, works on a project.

Whether collectively or individually, maintaining the application necessitates adherence to specific rules to uphold project quality and minimize issues. Therefore, the purpose of this template, which centers on the development setup, is to aid in achieving the goal by providing essential configuration and addressing concerns, ultimately resulting in a better product.

## Features

- 🐶 Configuring husky, a popular Git hook tool, simplifies the setup and management of pre-commit hooks. Currently, pre-commit, pre-push, and commit-msg hooks have configured.

- 💅 Configuring lint-staged allows for code linting before committing, ensuring that no errors make their way into the repository and enforcing consistent code style.

- ✍️ Configuring commitlint enables linting of commit messages, enforcing a consistent format that promotes clarity and understanding the changes made to your project.

- 🧹 Removing logs in production mode improves performance and prevents potential concerns that may arise from logging.

- 🗂️ Setting up configuration for paths with the @/ absolute prefix provides a better and more convenient experience when importing files.

## Installation (Create New Project)

**Step 1**

```
npx react-native init MyApp --template react-native-awesome-template

JavaScript in 2024: A Look at the Future
Tags: javascript, webdev, programming
Published: 2024-04-27 08:15:14

JavaScript continues to evolve, bringing with it a host of new features that promise to make coding more efficient, readable, and robust. Here’s a look at some of the most exciting developments in JavaScript for 2024

## ECMAScript® 2024 (ES15) Updates

The proposed features of ES2024 promise to enrich the JavaScript ecosystem and empower developers with more tools at their disposal. Here are some of the key features:

### Well-formed Unicode Strings:

This feature aims to improve how JavaScript handles Unicode strings, which are essential for representing a wide range of characters from different languages and symbols. The update ensures consistent and accurate processing of these strings across different JavaScript environments.

### Temporal
In response to the need for better date management in JavaScript, the Temporal proposal offers a standard global object to replace the Date object. This new feature addresses many of the issues that have caused developers much pain when working with dates in JavaScript.

### Pipe Operator

The pipe operator is another exciting feature expected to land in 2024. This operator allows you to chain together functions in a more readable and functional manner.

### Records and Tuples

Records and Tuples provide JavaScript with compound primitive values. Unlike objects and arrays, records and tuples are immutable and compared by value.

### Regular Expressions /v flag

The /v flag for regular expressions is another anticipated feature. This flag changes the syntax and semantics of regular expressions to match the behaviour of other programming languages.

### Decorators
Decorators, a feature already popular in languages like Python and Java, are finally coming to JavaScript. Decorators allow you to wrap functions and classes with additional behaviour.

### Object.groupBy()

The Object.groupBy() function is a new addition that simplifies the process of grouping objects based on a specific property.

### Promise.withResolvers()

Promise.withResolvers() is a new method that provides a more intuitive way to work with Promises.

### Conclusion
These are just a few of the exciting new features coming to JavaScript in 2024. As the language continues to evolve, developers can look forward to more efficient, readable, and robust coding experiences. Stay tuned for more updates as we continue to unwrap the gifts of JavaScript’s evolution!
