Mongoose Learning (3) -- set Environment Variables

For example, my code database code can be divided into Chinese and English sites. Each table has a site_code field to distinguish,

The two sites are deployed on different people servers. In this case, we will use system environment variables to differentiate them,

Set the environment variables in Mac

Vim ~ /. Bash_profile

Add a line of code export site_code = 'cn'

In UNIX, run the export site_code = 'cn' command on the terminal.

Enter the following command once after setting in Mac to see if there is any value output.

Source ~ /. Bash_profilenodeprocess.env.site_code

If the terminal outputs 'cn', congratulations!
