Generates a stable unique dev-server port (3000-8999) from a project name and updates the project's port configuration.

About

Generates a stable unique dev port from a project name so the same project always maps to the same port, and updates the project's port config. A developer uses it to avoid port collisions across multiple local projects.

Hashes the project name to a stable port in 3000-8999
Updates .env, package.json, or vite.config port config with minimal changes

Project Port Generator

为项目生成稳定唯一的端口号（范围 3000-8999），同一项目名永远返回相同端口。

端口生成算法

def generate_port(project_name: str) -> int:
    hash_value = sum(ord(c) * (i + 1) for i, c in enumerate(project_name))
    return 3000 + (hash_value % 6000)

使用场景

1. 查询项目端口

用户询问端口时，直接计算并告知：

项目 "lovstudio" 的端口号是：7965

2. 更新项目配置

检测并更新项目中的端口配置文件：

文件	配置方式
`.env` / `.env.local`	`PORT=<port>`
`package.json`	scripts 中的 `--port <port>`
`vite.config.ts`	`server.port: <port>`
`next.config.js`	通常使用 .env

更新时优先使用 .env 方式，最小侵入性。

3. 启动开发服务器

PORT=$(scripts/hashport.sh) pnpm dev

脚本

运行 scripts/hashport.sh [project-name] 生成端口：

# 使用当前目录名
./scripts/hashport.sh
# 输出: 7965

# 指定项目名
./scripts/hashport.sh my-project
# 输出: 5123

端口冲突处理

若端口被占用： 1. 提示用户哪个进程占用了端口 2. 建议使用 lsof -i :<port> 查看 3. 可追加后缀生成备用端口：generate_port("project-dev")

#!/bin/bash
# 基于项目名生成稳定端口号
# Usage: hashport.sh [project-name]
# 如不指定项目名，使用当前目录名

name="${1:-$(basename "$PWD")}"

# 计算哈希值
hash=0
for ((i=0; i<${#name}; i++)); do
    char="${name:$i:1}"
    ord=$(printf '%d' "'$char")
    hash=$((hash + ord * (i + 1)))
done

# 生成端口 (范围 3000-8999)
port=$((3000 + (hash % 6000)))

# 检查端口状态
if command -v lsof &>/dev/null && lsof -i :"$port" &>/dev/null; then
    proc=$(lsof -i :"$port" | awk 'NR==2 {print $1}')
    echo "$port  ← $name (occupied by $proc)" >&2
else
    echo "$port  ← $name" >&2
fi

echo "$port"
