Azure Artifacts’ instructions for .npmrc say to base64 encode the password. Do not do this for bun install. Bun base64 encodes the password for you if needed.
Azure Artifacts is a package management system for Azure DevOps. You can use it to host your own private npm registry, along with other types of packages.

​
Configure with bunfig.toml

To use it with bun install, add a bunfig.toml file to your project with the following contents. Replace my-azure-artifacts-user with your Azure Artifacts username, such as jarred1234.
bunfig.toml
[install.registry]
url = "https://pkgs.dev.azure.com/my-azure-artifacts-user/_packaging/my-azure-artifacts-user/npm/registry"
username = "my-azure-artifacts-user"
# You can use an environment variable here
password = "$NPM_PASSWORD"
Then assign your Azure Personal Access Token to the NPM_PASSWORD environment variable. Bun automatically reads .env files, so create a file called .env in your project root. Don’t base64 encode the token; Bun does that for you.
.env
NPM_PASSWORD=<paste token here>

​
Configure with environment variables

To configure Azure Artifacts without bunfig.toml, set the NPM_CONFIG_REGISTRY environment variable. The URL should include :username and :_password as query parameters. Replace <USERNAME> and <PASSWORD> with your own values.
terminal
NPM_CONFIG_REGISTRY=https://pkgs.dev.azure.com/my-azure-artifacts-user/_packaging/my-azure-artifacts-user/npm/registry/:username=<USERNAME>:_password=<PASSWORD>

​
Don’t base64 encode the password

Azure Artifacts’ instructions for .npmrc say to base64 encode the password. Do not do this for bun install. Bun base64 encodes the password for you if needed.
If the password ends with ==, it is probably base64 encoded.
To decode a base64-encoded password, open your browser console and run:
browser
atob("<base64-encoded password>");
Alternatively, use the base64 command line tool, though the password may end up in your shell history:
terminal
echo "base64-encoded-password" | base64 --decode
