jenkins构建node项目

安装插件

```
nodeJs(14.16.0)
```

配置步骤

执行shell（在jenkins里执行）

pwd

# 安装依赖(非必须)
npm --registry https://registry.npmmirror.com/ install
# 构建项目
npm run build:test

# 删除除 node_modules和dist 以外的所有内容
ls | grep -v 'node_modules\|dist' | xargs  rm -rf

Send files or execute commands over SSH(通过ssh远程执行shell)

export app_version='1.0'

cd $DOCKER_WORKSPACE/$JOB_NAME

mkdir -p ./nginx/conf.d/

# 添加default.conf文件
tee ./nginx/conf.d/default.conf <<-'EOF'

        index  index.html index.htm;
        try_files $uri $uri/ /index.html; # 用于解决刷新页面后，显示404的问题
    }
