如何解决后端开发时使用WebSocket服务部署问题

如何解决后端开发时使用WebSocket服务部署问题

WebSocket服务使用的为hocuspocus技术，启动WebSocket服务的命令为：

npx @hocuspocus/cli --port 2345 --sqlite

该方式会自动下载依赖包，并进行启动服务。

启动服务的脚本如下：

(base) vm1:~/code/smartdoc_backend_v3/bin$ cat start-websock.sh 
#!/bin/sh

nohup npx @hocuspocus/cli --port 2345 --sqlite > websocks.log 2>&1 &

netstat -anlp | grep 2345

实际部署时，可能会遇到部署失败，主要原因为网络问题。

可以参考下面的步骤进行处理：

1. 配置代理，保障环境可以访问Google。
2. 清理环境，设置仓库为
   registry = “https://registry.npmjs.org/”
3. 在对应的目录中，执行npm的安装
   npm i @hocuspocus/cli
4. 启动WebSocket服务
5. 检查服务的启动状态。

具体操作信息如下：
