Is there a way to display NODE_ENV from the command line?
node.jsnode.js Problem Overview
Please, answers here all refer to a something called process.env.NODE_ENV, but echo $process.env.NODE_ENV from the command line did not work. Any ideas?
node.js Solutions
Solution 1 - node.js
Use echo $NODE_ENV. The command line is a shell, probably bash and that's the bash syntax to print the value of an environment variable.
Solution 2 - node.js
If you have defined NODE_ENV variable then you should be able to see this by typing node in the command prompt which will open the node cell and then type process.env.NODE_ENV.
To check the existing env variables .. type this .. process.env
Solution 3 - node.js
You call list all variables for Macs available for your project directory with...
printenv
I use this often to look for the NODE_ENV and other variables.
Solution 4 - node.js
go to node REPL, and then give process.env.NODE_ENV and the variable process is scoped inside nodejs process, not in your shell process.
sk3037@saravana:~/src$ node
> process.env.
Solution 5 - node.js
Setp-by-step windows CMD NODE_ENV:
-
> set NODE_ENV=my_node_env (defines NODE_ENV)
-
> node (run node)
-
> process.env.NODE_ENV (show NODE_ENV)
After "set NODE_ENV" you can run the application, and it will use the set NODE_ENV. You can run your application with custom environment in pm2 without problem.
Solution 6 - node.js
To display the current node environment in windows, use:
> echo %NODE_ENV%
It wil output the environment on the command line like:
development
Solution 7 - node.js
- Find the Id of the process you are running by executing
ps aux | grep node - Look at the environment variables used by that process by executing
less /proc/[your-id]/environ
Solution 8 - node.js
Have you set the NODE_ENV for process?
Here are some example.
Somewhere in code, you set the node environment to "production" or "development" or "any thing you want".
And do some stuff according to your node environment.
process.env.NODE_ENV="production";
//others coding
if(process.env.NODE_ENV === "production")
{
//useblabla log level.
//use production log.
}
else if(process.env.NODE_ENV === "development")
{
//useblabla log level.
//use development log.
}
console.log(process.env.NODE_ENV); //"production"
