how to configure using environment variables

[batusai513]

Hello, I'm trying to figure out how to configure pnpm using environment variables, I've checked the documentation and it seems possible:

pnpm gets its configuration from the command line, environment variables, and .npmrc files

but it is not very clear how to achieve this, I suppose that as in npm, all configs will be prefixed, so for store-dir will become pnpn_config_store_dir, but that did not seems to work, what is the correct format to configure pnpm using env variables and what configs can be change using this method?

what I want to achieve is to configure pnpm to not move anything that writes into disk to /tmp/.pnpm folder

store-dir=/tmp/.pnpm/store
modules-dir=/tmp/.pnpm/node_modules
global-dir=/tmp/.pnpm/global
global-bin-dir=/tmp/.pnpm
state-dir=/tmp/.pnpm
cache-dir=/tmp/.pnpm/cache

I also tried adding all of those as command line arguments, but discovered that global-bin-dir and state-dir are treated as unknown arguments by the cli

Thanks.

Hey there,
Found your issue and figured out how it works, so I thought I'll share:

You have to prefix the config vars with npm_config_ and replace all - with _.
So the store-dir option becomes the npm_config_store_dir environment variable.

Hope this helps ^^
