How to see process.env after starting server-CodePudding

I am developing sample apps and would like to know process.env variables, I know console.log(process.env) will return its variables. But can I see them after run its server ?

npm start

I couldn't input anything in console. As I am new to node.js, will you please let me know. by switing NODE_ENV, it seems that development,staging,production is switched. So that I would like to comfirm them.

Thanks

CodePudding user response：

If you start your server in docker and don't pass custom variables to process.env in your app, you can see your env by docker command:

docker exec your_container env

Yet another way - create a specific route in your application that will be return you all data from process.env.

Something like this:

GET yourserver/api/system/env

But this way is not secured and you should think about protection of your system route.

UPD

Also you can call console.log(process.env) after server has been started.

await app.listen(3000);
console.log(process.env);
