7天用Go从零实现系列

7天能写什么呢?类似 gin 的 web 框架?类似 groupcache 的分布式缓存?或者一个简单的 Python 解释器?希望这个仓库能给你答案。

推荐先阅读 Go 语言简明教程,一篇文章了解Go的基本语法、并发编程,依赖管理等内容。

推荐 Go 语言笔试面试题,加深对 Go 语言的理解。

推荐 Go 语言高性能编程(项目地址),写出高性能的 Go 代码。

期待关注我的「知乎专栏」和「微博」,查看最近的文章和动态。

7天用Go从零实现Web框架 - Gee

Gee 是一个模仿 gin 实现的 Web 框架,Go Gin简明教程可以快速入门。

7天用Go从零实现分布式缓存 GeeCache

GeeCache 是一个模仿 groupcache 实现的分布式缓存系统

7天用Go从零实现ORM框架 GeeORM

GeeORM 是一个模仿 gormxorm 的 ORM 框架

gorm 准备推出完全重写的 v2 版本(目前还在开发中),相对 gorm-v1 来说,xorm 的设计更容易理解,所以 geeorm 接口设计上主要参考了 xorm,一些细节实现上参考了 gorm。

7天用Go从零实现RPC框架 GeeRPC

GeeRPC 是一个基于 net/rpc 开发的 RPC 框架 GeeRPC 是基于 Go 语言标准库 net/rpc 实现的,添加了协议交换、服务注册与发现、负载均衡等功能,代码约 1k。

WebAssembly 使用示例

具体的实践过程记录在 Go WebAssembly 简明教程

  • 示例一:Hello World | Code
  • 示例二:注册函数 | Code
  • 示例三:操作 DOM | Code
  • 示例四:回调函数 | Code

What can be accomplished in 7 days? A gin-like web framework? A distributed cache like groupcache? Or a simple Python interpreter? Hope this repo can give you the answer.

Web Framework - Gee

Gee is a gin-like framework

  • Day 1 - http.Handler Interface Basic Code
  • Day 2 - Design a Flexiable Context Code
  • Day 3 - Router with Trie-Tree Algorithm Code
  • Day 4 - Group Control Code
  • Day 5 - Middleware Mechanism Code
  • Day 6 - Embeded Template Support Code
  • Day 7 - Panic Recover & Make it Robust Code

Distributed Cache - GeeCache

GeeCache is a groupcache-like distributed cache

  • Day 1 - LRU (Least Recently Used) Caching Strategy Code
  • Day 2 - Single Machine Concurrent Cache Code
  • Day 3 - Launch a HTTP Server Code
  • Day 4 - Consistent Hash Algorithm Code
  • Day 5 - Communication between Distributed Nodes Code
  • Day 6 - Cache Breakdown & Single Flight | Code
  • Day 7 - Use Protobuf as RPC Data Exchange Type | Code

Object Relational Mapping - GeeORM

GeeORM is a gorm-like and xorm-like object relational mapping library

Xorm's desgin is easier to understand than gorm-v1, so the main designs references xorm and some detailed implementions references gorm-v1.

  • Day 1 - database/sql Basic | Code
  • Day 2 - Object Schame Mapping | Code
  • Day 3 - Insert and Query | Code
  • Day 4 - Chain, Delete and Update | Code
  • Day 5 - Support Hooks | Code
  • Day 6 - Support Transaction | Code
  • Day 7 - Migrate Database | Code

RPC Framework - GeeRPC

GeeRPC is a net/rpc-like RPC framework

Based on golang standard library net/rpc, GeeRPC implements more features. eg, protocol exchange, service registration and discovery, load balance, etc.

  • Day 1 - Server Message Codec | Code
  • Day 2 - Concurrent Client | Code
  • Day 3 - Service Register | Code
  • Day 4 - Timeout Processing | Code
  • Day 5 - Support HTTP Protocol | Code
  • Day 6 - Load Balance | Code
  • Day 7 - Discovery and Registry | Code

Golang WebAssembly Demo

  • Demo 1 - Hello World Code
  • Demo 2 - Register Functions Code
  • Demo 3 - Manipulate DOM Code
  • Demo 4 - Callback Code
