How can I define the NODE_ENV variable on macOS to “development” by default?

I ran into an issue where running ‘npm install’ no longer installs my devDependencies and after some digging I noticed that when I run ‘echo $NODE_ENV’ is shows ‘production’.

I’m able to run this command to switch it:

export NODE_ENV=development

But that’ll disappear on each restart.

Is there a way to have it so my local is always running development? For me there’s no reason why I’d have production set and if for whatever reason I did need it I would prefer to have to enable it vs disabling it each time.
