Usage
CLI Tool
After you've installed @hutson/set-npm-auth-token-for-ci-cli
, you can call the tool based on whether you installed it globally or locally:
Globally

library.
How It Works
When you need to authenticate with an npm-compatible package registry using the npm
or yarn
package manager, and you are authenticating with that registry from within a Continuous Integration environment, you are strongly encouraged to use an authentication token placeholder.
For example, your package may have an .npmrc file that configures a private registry:
registry=https://registry.example.com/
To authenticate you could set an authentication token in the .npmrc
file:
//registry.example.com/:_authToken=SECRET
Now every authenticated request to registry.example.com/
will receive the SECRET
token.
However, you may not want to commit your authentication token to your source repository where other people will have access to the token.
Instead, you can inject your token into your Continuous Integration environment using an environment variable, and then configure npm
and yarn
to get the authentication token from the environment.
That's where set-npm-auth-token-for-ci-cli
helps. set-npm-auth-token-for-ci-cli
gets the registry used by the current package and writes an authentication token placeholder to the correct .npmrc
file.
If there's an .npmrc
file located within the current directory, and that directory contains an package.json
file, then set-npm-auth-token-for-ci-cli
will write the authentication token placeholder into that .npmrc
file. Otherwise the authentication token placeholder will be written into the .npmrc
file located at the root of the user's home directory.
The placeholder is of the form: [REGISTRY]/:_authToken=${NPM_TOKEN}
For example, if the package is configured to use our example npm registry, the placeholder will be: //registry.example.com/:_authToken=${NPM_TOKEN}
When npm
or yarn
need to authenticate, they retrieve the value assigned to _authToken
, which is ${NPM_TOKEN}
, and then replace ${NPM_TOKEN}
with the value of the NPM_TOKEN
environment variable.
Debugging
To assist users of set-npm-auth-token-for-ci-cli
with debugging the behavior of this module we use the debug utility package to print information to the console. To enable debug message printing, the environment variable DEBUG
, which is the variable used by the debug
package, must be set to a value configured by the package containing the debug messages to be printed.
To print debug messages on a unix system set the environment variable DEBUG
with the name of this package prior to executing a tool that invokes this module:
DEBUG=set-npm-auth-token-for-ci set-npm-auth-token-for-ci-cli
On the Windows command line you may do:
set DEBUG=set-npm-auth-token-for-ci
set-npm-auth-token-for-ci-cli
Node Support Policy
We only support Long-Term Support versions of Node.
We specifically limit our support to LTS versions of Node, not because this package won't work on other versions, but because we have a limited amount of time, and supporting LTS offers the greatest return on that investment.
It's possible this package will work correctly on newer versions of Node. It may even be possible to use this package on older versions of Node, though that's more unlikely as we'll make every effort to take advantage of features available in the oldest LTS version we support.
As each Node LTS version reaches its end-of-life we will remove that version from the node
engines
property of our package's package.json
file. Removing a Node version is considered a breaking change and will entail the publishing of a new major version of this package. We will not accept any requests to support an end-of-life version of Node. Any merge requests or issues supporting an end-of-life version of Node will be closed.
We will accept code that allows this package to run on newer, non-LTS, versions of Node. Furthermore, we will attempt to ensure our own changes work on the latest version of Node. To help in that commitment, our continuous integration setup runs against all LTS versions of Node in addition the most recent Node release; called current.
JavaScript package managers should allow you to install this package with any version of Node, with, at most, a warning if your version of Node does not fall within the range specified by our node
engines
property. If you encounter issues installing this package, please report the issue to your package manager.
