Private NPM Buildkite Plugin

A Buildkite plugin to allow pipeline steps to easily install private packages from an npm repository.

Note this plugin should work equally well despite any personal preferences for either yarn or npm.

Example

To read the value from an environment variable named MY_TOKEN when the plugin executes, use the env fiels.

steps:
  - command: yarn install
    plugins:
      - seek-oss/private-npm#v1.1.1:
          env: "MY_TOKEN"

To read the value from a file named my_token_file, use the file field.

steps:
  - command: yarn install
    plugins:
      - seek-oss/private-npm#v1.1.1:
          file: "my_token_file"

Alternatively you can read the token directly from any value exposed toxs your pipeline.yml file. However, this approach is discoraged in favour of using with the env or file fields. This functionality remains in the interest of backwards compatibility.

steps:
  - command: yarn install
    plugins:
      - seek-oss/private-npm#v1.1.1:
          token: ${MY_TOKEN}

You can also specify a custom npm registry if you are using your own mirror.

steps:
  - command: yarn install
    plugins:
      - seek-oss/private-npm#v1.1.1:
          env: "MY_TOKEN"
          registry: //myprivatenpm.com/

Configuration

NOTE Even thought env, file and token are described as optional, at least one must be set or the plugin will fail.

env (optional)

The value of the NPM token will be read from the agent environment when the plugin executes. This is useful in working around cases where eager binding of variables in pipeline.yml means some variables are not present in the environment when the configuration file is parsed.

file (optional)

The value of the NPM token will be read from a file on the agent when the plugin executes. This is useful when working with secret that are created as files on the filesystem when a build is initiated.

token (optional)

The value of the NPM token will be read from a variable which is available to the Buildkite YAML parsing context.
This value is interpolated when the YAML configuration is parsed by the Buildgent agent and provided to the plugin "as is".

Example: ${MY_TOKEN}

NOTE: Don't put your tokens into source control. Don't use web interfaces you don't control to inject them into your environment either. Rather use a Secrets Manager. If you are an AWS user, perhaps consider the aws-sm-buildkite-plugin which works well with this plugin.

NOTE: There is anecdotal evidence to suggest that using NPM_TOKEN as the variable name containing the token can intermittently cause the token to become empty. It is advised to use a different name as has been done in these docs.

registry (optional)

The path to a private npm repository. Please ensure you supply the trailing /!

Example: //myprivatenpm.com/
