How to enable/disable Redis cache with an environment variable

[mnlbox]

Hi,

I already setup the response caching based on Redis in my app but I want to enable/disable the cache with an environment variable then I can toggle it based on a different environment or I can disable it for testing purposes easily. How can I use env variables in the if property of this plugin?

plugins:
  - responseCache:
      if: 'context.headers.authorization != null' <---- how can I read the env variables here?

if: 'env.DISABLE_CACHE != null'

@ardatan Thanks for your reply but I'm getting this error with the syntax that you mentioned:

I tried this setting too, similar to the example in the doc here:

if: "context.headers['enable-cache'] === 'true'"

And it throws this error:

ReferenceError: context is not defined

Did I miss anything? If it's a bug I can create an issue for it.

I guess this question is related to this:
#5327

[ardatan]

It is not possible to enable/disable per context. You can try accessing process.env.

[mnlbox]

@ardatan Any idea on this?

[ardatan]

You can try process.env maybe? If it still doesn'twork, I need a reproduction.
