How to use Google library in n8n

[rajesh-kumar]

Hi Team,

Anyone can help, how to use google library in function node or any way.
I am running n8n using docker.
included this variable,
-e NODE_FUNCTION_ALLOW_BUILTIN="*" -e NODE_FUNCTION_ALLOW_EXTERNAL="axios,moment,uuid,@google-cloud/bigtable"

facing below error,
ERROR: Cannot find module ‘@google-cloud/bigtable’ [Line 377]

Thanks.

Hi @rajesh-kumar, as with your previous questions around external modules, the npm package @google-cloud/bigtable is not part of n8n. So before you can use it, you’d first need to install it.

The exact steps will depend on how you have deployed n8n as per this thread:

How to use external libs in function node?

The npm module still has to be installed to be able to be used. How to, for example, create an own docker image to do that, can be found for example here: https://community.n8n.io/t/help-not-been-able-to-import-external-modules/686/7

Ok @MutedJam,

Thanks

No worries at all. Personally, I avoid installing external packages as this usually increases the maintenance effort. You might want to consider calling REST APIs directly through the HTTP Request node where possible. For a few pointers as to how to authenticate with Google’s REST APIs in n8n you could check this thread:

Hi @ConfusedAnt, so I gave this a go on my end and could fetch my media items using the GET https://photoslibrary.googleapis.com/v1/mediaItems endpoint: [image]

Example Workflow

To set up the credentials, I have used these settings in n8n: [image] [image] I noticed you have a different access token URL - I am using https://oauth2.googleapis.com/token found here. I’ve also added these scopes: https://www.googleapis.com/auth/photoslibrary https://www.googleapis.com/auth/photoslibrary.sharing…
