Introduction to RTK Query ❗

1️⃣ Introduction

RTK Query is a library for managing API queries in Redux applications.
It provides a simple and powerful way to manage request status, caching and re-ex*****on of requests. RTK Query also integrates with standard Redux tools such as Redux Toolkit and Redux DevTools.

2️⃣ Working Principle

The way RTK Query works is that it creates a cache to store the results of API queries. When a React component requests data, RTK Query checks if the data is in the cache and returns it if it is present. If there is no data in the cache, RTK Query makes a query to the API and stores the result in the cache.

3️⃣ createApi()

This is the main RTK Query function that lets you create an API with specified configuration options. It takes a configuration options object that contains information about API endpoints, query options, caching options and other parameters.

4️⃣ useQuery()

This is a React hook that makes it easy to run API queries from React components.
It takes the API endpoint name and query options, and returns an object with query data, query state, and a method to re-execute the query.

5️⃣ useMutation()

This is a function that allows you to send data to the server and process the results of the query ex*****on. When you call useMutation, RTK Query automatically generates an action function that executes the request to the server and processes the results. It returns an object that contains information about the status of the request, such as load, success, or error.

6️⃣ Redux Toolkit

RTK Query integrates with Redux Toolkit, making it even more user-friendly.
The library includes many Redux actions and selectors, making it easy to manage application state and update data in real time.

5 benefits of Using Typescript❗

Although TypeScript may seem new and complicated to newcomers, it can be very useful for so development.

2️⃣ TypeScript is supported by all modern browsers, and can also be used on a server (using Node.js, for example). It also has widespread support in the development community and is used by many large projects.

3️⃣ One of the key features of TypeScript is the ability to define types of variables, functions, and other program elements. This makes the code more robust, readable, and maintainable. TypeScript also supports typed arrays, objects, classes, and interfaces.

4️⃣ Extended OOP support: TypeScript supports classes, interfaces, inheritance, and multiple inheritance, making code more modular, reusable, and maintainable.

5️⃣ Finally, TypeScript provides the ability to use static code analysis tools such as TypeScript Compiler and Linter. These tools can help detect bugs in the code as well as provide additional information about types and other characteristics of program elements.

In the next post, I'll talk in more detail about the benefits of TypeScript and how to use them in practice. We'll break down the main tricks of the language with examples so that you can better understand how it can improve your programming experience

Introduction to Docker❗

1️⃣ Introduction

Docker is a platform for creating, deploying, and managing applications using containers. Containers are lightweight and isolated environments in which applications and their dependencies run. Docker simplifies application development and deployment by providing a consistent environment and packing everything you need to run your application into a single container.

2️⃣ Advantages

A major benefit of Docker is that it provides a single and independent environment for an application, making it easier to test, deploy and scale applications. This allows developers and operators to maintain consistency between different environments, including on-premises, test and product environments.

3️⃣ Advantages(2)

Docker also has a number of other advantages, including fast container creation and deployment, the ability to run multiple applications in a single container, and automatic scaling and resource management. All of this makes Docker one of the most popular tools for application containerization.

4️⃣ Conclusion

In general, Docker is a powerful tool to simplify application development, testing and deployment. It allows you to create a single and independent environment for your application, which makes life easier for developers and operators, and reduces setup time

React Query❗

1️⃣ Introduction

React Query is a state management library that simplifies working with data in a React application. It is designed to perform server queries and manage data caching. It can greatly speed up the application development process and reduce the amount of code.

2️⃣ Basic principles

The basic principles of React Query are queries, mutations, and caching. Queries are for retrieving data from the server, mutations are for changing data on the server, and caching is for storing data in the browser's local storage. React Query automatically handles all queries and mutations, and manages data caching.

3️⃣ Examples of use

React Query allows you to work with both REST APIs and GraphQL APIs. Each type of API has its own functions that can be used to perform queries and mutations. React Query also provides the ability to customize queries and error handling.

4️⃣ More

React Query provides additional features that can be used for error handling, data refetching, and cache invalidation. Error handling allows you to handle errors that occur during query ex*****on, refetching allows you to update data on the server, and cache invalidation allows you to remove obsolete data from the browser's local storage.

5️⃣ Recommendations

When using React Query, i recommend following the principle of sole responsibility and breaking down your application into smaller, more manageable components.
In addition, pay attention to the structure of your cache and organize it so that it is easily accessible and scalable.
Also, don't forget to update the data when needed with cache refetching and handicapping features.
Finally, try to avoid redundant state management logic in your components and delegate it to React Query instead.
