Multi NPM registries usage made easy (Azure DevOps)

#azuredevops #npm #npmrc

The problem

I use Azure DevOps for development and have several projects in it.

And I am using the feeds possibility from Azure DevOps.
This means that I need to change the NPMRC each time I switch projects so that it uses the correct registry.

Or you put that in a .npmrc in the repository but then you need to still handle the authentication somehow...

What?

I thought there must be an easier way.

Inspired by the npmrc project I created my own solution, more tailored for Azure DevOps.

But you should still be able to use it as a npmrc switcher, just like the other package but with some added functionality.
Like an interactive list.

To break it down a bit what it does:

It will create an NPMRC with the provided feed-name as registry AND create a PAT that is allowed to pull data from the artifact feed.
And provide options to automatically renew the PAT.

So how to use it?

Easiest

Only one parameter is required

feedName (the name of the Artifact feed as created in Azure DevOps)

Then there are a few defaults:

name of the NPMRC (defaults to the directory name)

Next to the name of the NPMRC and the feedname we also need the details of the Azure DevOps Organization and Project.

These two values can be retrieved from the repository.url if that is set in the package.json

azOrganization (first part of Azure DevOps url)
azProject (second part of Azure DevOps url)

Example Azure DevOps url: https://dev.azure.com/henkvandenbrink/kitchensink

azOrganization = henkvandenbrink

azProject = kitchensink

feedName = As specified

Full example:

snmprc create feed-name

This will generate an NPMRC with the specified feed-name as registry, the azure details are retrieved from package.json and current directory name is used as name.
