ports

Next.js 3002

Run and Stop in Local / 本地，跑起来与停止

# inside project root folder
# without pm2
npm install && npm run dev  
# or with pm2
npm install && npm start
# if you are linux root, use below command to install 
# adduser someusername
# su -l someusername
# npm i

You need to quit manually because we used pm2
需要手动退出，因为用了pm2:

npm stop

postinstall

we executed bellow commands in postinstall:

installed pm2 and pm2-logrotate

git update-index --skip-worktree packages/helper/globalConfig.prod.mjs

and after installed packages/helper, we will generate a keypair for jwt use.

production

Modify packages\helper\globalConfig.prod.mjs
( mongodb / rabbitmq / dynJSPath / nodemailer )
and packages\web\.env.production
(nextHost / i18nDebug / mongodb)
