===== Setup npmrc for azure artifacts in WSL 2 =====


I recently got a windows machine from work, since more comfortable with mac or linux, so I installed [[:windows:wsl|WSL 2 (ubuntu)]] to setup nodejs development environment in it, I followed the [[https://docs.microsoft.com/en-us/azure/devops/artifacts/npm/npmrc?view=azure-devops&tabs=windows#set-up-authentication-on-your-dev-box|guide]], and created the auth token from azure personal access token:
<code>
echo -n [personal-access-token] | base64
</code>

then added following to ''.npmrc'':
<code>
; begin auth token
//pkgs.dev.azure.com/<yourOrganization>/_packaging/<yourFeed>/npm/registry/:username=[ANY_VALUE_BUT_NOT_AN_EMPTY_STRING]
//pkgs.dev.azure.com/<yourOrganization>/_packaging/<yourFeed>/npm/registry/:_password=[BASE64_ENCODED_PERSONAL_ACCESS_TOKEN]
//pkgs.dev.azure.com/<yourOrganization>/_packaging/<yourFeed>/npm/registry/:email=npm requires email to be set but doesn't use the value
//pkgs.dev.azure.com/<yourOrganization>/_packaging/<yourFeed>/npm/:username=[ANY_VALUE_BUT_NOT_AN_EMPTY_STRING]
//pkgs.dev.azure.com/<yourOrganization>/_packaging/<yourFeed>/npm/:_password=[BASE64_ENCODED_PERSONAL_ACCESS_TOKEN]
//pkgs.dev.azure.com/<yourOrganization>/_packaging/<yourFeed>/npm/:email=npm requires email to be set but doesn't use the value
; end auth token
</code>

but this only leads to an error:
<code>
npm ERR! code E401
npm ERR! Unable to authenticate, need: Bearer authorization_uri=https://login.windows.net/a1b03033-8a3d-4443-a90b-0f3298ffbf90, Basic realm="https://pkgsprodeau1.pkgs.visualstudio.com/", TFS-Federated

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/dcai/.npm/_logs/2021-02-04T22_20_51_870Z-debug.log</code>

Same npmrc file works on macbook just not wsl2, coworker who directly work on windows told me they use [[https://www.npmjs.com/package/vsts-npm-auth|Azure DevOps (formerly VSTS) Auth helper]] for authentication on windows 10, so I installed the auth helper on windows directly, ran it by providing azure artifacts registry url, it then generated a .npmrc file under ''c:\Users\[username]\.npmrc'', I copied this file to wsl2, and it worked! The generated npmrc file looks like this:

<code>
//pkgs.dev.azure.com/[org]/_packaging/[feed]/npm/registry/:username=VssSessionToken
; This is an unencrypted authentication token. Treat it like a password. DO NOT share this value with anyone, including Microsoft support.
//pkgs.dev.azure.com/[org]/_packaging/[feed]/npm/registry/:_password=[generated-token]
; The npm client won't use username and _password without an email set, but the service doesn't use the email value. The following is an arbitrarily made-up address.
//pkgs.dev.azure.com/[org]/_packaging/[feed]/npm/registry/:email=not-used@example.com
//[org].pkgs.visualstudio.com/_packaging/[feed]/npm/registry/:username=VssSessionToken
; This is an unencrypted authentication token. Treat it like a password. DO NOT share this value with anyone, including Microsoft support.
//[org].pkgs.visualstudio.com/_packaging/[feed]/npm/registry/:_password=[generated-token]
; The npm client won't use username and _password without an email set, but the service doesn't use the email value. The following is an arbitrarily made-up address.
//[org].pkgs.visualstudio.com/_packaging/[feed]/npm/registry/:email=not-used@example.com
</code>

So happy I don't have to use powershell and bulky IDE.
