Can npm be used AWS CodeArtifact for private packages, while all npm.org is used with public packages?

Question

The docs read a bit like the developer is supposed to give over all "package registry duties" to AWS CodeArtifact. But I want to continue using npm.org for some packages.

Given a javascript app that uses private and public packages, can I setup npm/AWS so:

• privately scoped packages (my code) are pulled from AWS CodeArtifact, and
• publically scoped packages (e.g. lodash) are pulled npm.org?

There is way to explicitly set two npm registries, therefore achieving what you want. Instead of using aws codeartifact login --tool npm --repository my-repo --domain my-domain to login into aws you should use a more granular approach use the following commands:

# get endpoint 
endpoint = aws codeartifact get-repository-endpoint --domain my_domain --domain-owner 111122223333 --repository my_repo --format npm

# set a scoped registry
npm config set registry endpoint --scope=@my-package

# get token
token = aws codeartifact get-authorization-token --domain my_domain --domain-owner 111122223333 --repository my_repo

# set token
npm config set //my_domain-111122223333.d.codeartifact.region.amazonaws.com/npm/my_repo/:_authToken=token

# always truth
npm config set //my_domain-111122223333.d.codeartifact.region.amazonaws.com/npm/my_repo/:always-auth=true

These commands are a deconstruction of aws codeartifact login --tool npm --repository my-repo --domain my-domain (more info), with the difference that instead of setting a general registry at your .npmrc file (used to set configurations for your npm) will set a scoped registry (more info). In this way you will be able to have you fetch your packages from the sources you want.
