@olivermrbl do you think that pr could be merge at some point?

[olivermrbl]

@adrien2p Yes, I will give this a review tomorrow :)

[olivermrbl]

I am attempting to configure ADMIN_CORS with a regex, but I can't seem to make it work. Am I doing something wrong here?

const ADMIN_CORS = `/http\:\/\/localhost\:700\d`

This should allow requests from origins http://localhost:7000, http://localhost:7001, etc.

[adrien2p]

@olivermrbl I ve open a pr in the CORS repo as I can't seam to be able to find the culprit expressjs/cors#292

It is also possible that the changeset need to be updated

[adrien2p]

It is now working properly, just need to double the \ to avoid them to be escaped
/http:\\/\\/localhost:700\\d+$/

That's a great functionality.

Question: I believe we will increase quite a lot the size of the plugins if they now depend on medusa core. Should we think about separating the "utils" to a new package?
ps: considering that some people are not using package managers that reuse installed node_modules

I see what you mean, but plugins already depends on the core as they can extend strategies, interfaces, services, and also are already using some utilities. In that case I am afraid it would mean to separate all of those in different packages. Generally speaking, since the plugins have no dependency to the core, but only as a peer dependency, I don't think it is a problem since the core will then not be installed by the plugin. they are normally used in the server and the server install medusa core already wdyt? let me know if I have miss understood something

[carlos-r-l-rodrigues]

Sorry, disregard my comment. I see it's listed as a peerDependencies. Even npm will reuse medusa-code if that's is installed.

[adrien2p]

@olivermrbl finally all green

[olivermrbl]

Think we should add a guide for this in our documentation. Wdyt? @adrien2p

[adrien2p]

Yes I agree, we can take the examples we've put in comments of that pr? And we should mention the usage of the utilities in custom routes

[shahednasser]

I'll add an issue for it in Linear 👍🏻

[srindom]

@olivermrbl, @adrien2p - can we merge this?

[olivermrbl]

Yes, we were just awaiting a green pipeline. After resolving the conflict, we should be good 💪

[adrien2p]

@srindom yes sure, i ve tested it and was waiting for someone else to test as well
