Master Beego: Build High‑Performance Go Web Apps from Scratch

Beego is a free, open‑source Go web framework hosted on GitHub, offering MVC architecture, ORM, session, cache, logging and other modules for rapid development and deployment.

Installation and Upgrade

Install and upgrade Beego using Go's package manager with the go get command.

Detailed steps address common issues such as Git configuration and proxy settings.

Bee Tool Usage

Bee is a helper tool for quickly creating Beego projects, hot‑compiling, running, testing and deploying.

Key commands include bee new (create project), bee run (run project) and bee pack (package project).

Bee also supports code generation and database migration, simplifying the development workflow.

Quick Start

The guide creates a simple Beego project to demonstrate how to set up routing, write controllers, models and views.

Configuration and Parameters

Beego supports multiple configuration file formats (INI, JSON, XML, YAML); INI is the default.

The configuration file can set basic application parameters such as listening port, run mode, session settings, etc.

A detailed list of configuration parameters and explanations is provided to help developers tailor settings to their needs.

Routing

Beego supports static routes, regex routes and automatic routing.

Routes can be managed via annotations, function mapping or the Namespace feature, enabling complex routing rules and middleware integration.

Controller and Request Handling

Controllers inherit from beego.Controller.

Multiple HTTP methods (GET, POST, PUT, DELETE, etc.) are supported; Prepare and Finish methods allow initialization and cleanup.

Features include request data processing, session control, and XSRF filtering.

Model and ORM

The ORM module supports databases such as MySQL, PostgreSQL and SQLite3.

It provides full CRUD operations, advanced queries and transaction handling.

Model definition, field types, indexes and relational fields are supported for convenient database interaction.

View and Template

Beego uses Go's built‑in template engine, supporting template syntax, data binding and pagination.

Various template functions are provided, such as date formatting and string manipulation.

Advanced Programming

Beego offers in‑process monitoring and automatic API documentation.

Advanced features such as CORS and WebSocket are supported for complex applications.

Deployment and Operations

The guide describes multiple deployment methods: standalone, Supervisor, Nginx and Apache.

Detailed deployment steps and configuration examples help developers move applications to production environments.

Application Examples

Several sample applications are provided, such as an online chatroom, a short‑URL service and a Todo list, showcasing Beego's practical use cases.
