Node's package management and loading mechanisms: npm search xxx, npm view xxx, npm install xxx. Node.js file system operation APIs: Node.js's `fs` module provides synchronous (Sync) and callback/Promise-based asynchronous APIs for operating on local files and directories. Commonly used capabilities in daily development include reading, writing, appending, deleting, traversing directories, listening for changes, and so on. The following examples are based on C...

WebSocket and SSE Overview WebSocket Basics Definition: WebSocket is a full-duplex connection upgraded after an HTTP handshake, allowing clients and servers to push data bidirectionally over the same TCP channel, eliminating the need for repeated polling. Handshake Process: The client initiates an HTTP request with the Upgrade: websocket header; The server responds with 101 Switching Protocols, and both parties agree...

Transitioning: Reasons for a rapid, systematic transition to Go engineering:
To improve CRUD operations.
To gain experience with self-developed frameworks.
For colleagues aiming to deepen technical expertise, specializing and refining requirements.
To advance engineering practices, developing good coding standards and management capabilities.

The Importance of Engineering

Expectations for Senior Developers:
Good code standards.
Deep understanding of underlying principles.
Familiarity with architecture.
Familiarity with K8s basic architecture.
Expanding knowledge breadth and depth, and a standardized development system.

Four Major Stages:
Go language fundamentals.
Microservice development (e-commerce project practical experience).
Self-developed microservices.
Self-developed, then re...

grpc grpc grpc-go grpc seamlessly integrates protobuf protobuf. For those of you accustomed to using JSON and XML data storage formats, I believe most have never heard of Protocol Buffer. Protocol Buffer is actually a lightweight & efficient structured data storage format developed by Google, and its performance is truly much, much stronger than JSON and XML! protobuf…

For microservice development, create a microservice project where all project microservices will reside. Create `joyshop_srv`. We need to create user login and registration services, so we will create another directory `user_srv` under the project directory, along with `user_srv/global` (for global object creation and initialization), `user_srv/handler` (for business logic code), `user_srv/model` (for user-related models), `user_srv/pro...`

Project Structure Description: The user-web module is the user service Web layer module within the joyshop_api project, responsible for handling user-related HTTP requests, parameter validation, business routing, and calling backend interfaces. Below is the directory structure description: user-web/ ├── api/ # Controller layer, defines business interface processing logic ├── config/ # Configuration module, contains system configuration structs and reading logic ...
