How To Dev

Introduction This is a comprehensive page about the technologies I have shared in series format. You can view brief introductions and links to directly access each series you are interested in. In the field of software development, to deploy a product from the initial idea to its release, the standard process typically involves several stages as follows: Database : Designing and implementing the database according to business requirements, storing data during the system's operation. Backend : Handling the main logic of the system, communicating with the database and services. Frontend : Building the interface for users to interact with the system, which could be a desktop, mobile, or web application. This usually includes implementing UI/UX and integrating APIs from the backend. DevOps : Deploying the system for use, which can be done on a server or in the cloud. Testing : Applying testing methods to ensure the product meets the standards for release. Of course, these are just stan...

Introduction TypeORM is a powerful ORM (Object-Relational Mapper) library for the Node.js ecosystem, written in TypeScript. It allows developers to interact with databases using classes and objects instead of writing complex raw SQL queries. Key Advantages Excellent TypeScript support: Fully leverages decorators and type-checking, helping detect errors during development instead of at runtime. Supports multiple databases: Compatible with popular database management systems such as MySQL, PostgreSQL, SQLite, etc. Flexible patterns (Data Mapper & Active Record): Lets you choose the appropriate implementation style depending on project size (Data Mapper for large, complex projects; Active Record for smaller, quick projects). Migration management: Provides powerful tools to manage database schema changes systematically, helping synchronize changes across development teams. Query Builder: In addition to object-based operations, TypeORM provides a Query Builder for constructing complex q...

Introduction Redis is the world's fastest in-memory database. It offers cloud and on-premises solutions for caching, vector search, and NoSQL databases. In-memory is a concept related to how data is stored and accessed in a computer. When we talk about in-memory, we refer to storing data directly in the computer's RAM (Random Access Memory) rather than on a hard drive. Here are some key points about in-memory storage: Storing data in RAM :   When data is stored in-memory , it is kept in the computer's RAM . RAM has faster access speeds compared to hard drives, allowing for quicker data querying and processing.   The read and write speed of RAM is very fast, typically reaching several GB/s . The read and write speed of SSDs ( Solid State Drives ) usually starts from 320 MB/s and can reach thousands of megabytes per second. The read and write speed of HDDs ( Hard Disk Drives ) is lower, generally ranging from 80 MB/s to 160 MB/s. In-memory data is often used f...

Introduction NodeJS is an open-source and cross-platform JavaScript runtime environment . Here are some key points about NodeJS : V8 Engine : NodeJS runs on the V8 JavaScript engine , which is also the core of Google Chrome . This allows NodeJS to be highly performant. Asynchronous and Non-Blocking : NodeJS  uses an event-driven, non-blocking I/O model. It’s lightweight and efficient, making it ideal for data-intensive real-time applications. Single-Threaded : NodeJS  runs in a single process, handling multiple requests without creating new threads. It eliminates waiting and continues with the next request. Common Language : Frontend developers who write JavaScript for browsers can use the same language for server-side code in NodeJS . You can even use the latest ECMAScript standards without waiting for browser updates. This page is designed to compile articles related to NodeJS , including how to integrate it with various libraries and relevant tech stacks. I will cont...
