Node.js Environment variables

• node-env: Set NODE_ENV. (Default: development)

Configuration for projects living in subdirectories

• project-path: Optional Relative path of subdirectory containing the project (i.e. where the package.json is).

Configuration use for npm

• npm-args: Optional Allow to add extra args to npm i / npm ci command. (Default: "-q")

Configuration use npm ci command

• npm-ci-support: Optional Allow to use npm ci instead of npm install to install the npm modules into our resource. (Default: false)

Whatever tool you use to generate the encoded username and password string, try to encode the string admin:admin123, which should result in YWRtaW46YWRtaW4xMjM=. `
Another example for a valid setup is jane:testpassword123 resulting in amFuZTp0ZXN0cGFzc3dvcmQxMjM=.

In our demo we are using admin:123456 resulting in YWRtaW46MTIzNDU2

Example

resources:

  # a perfectly normal source repository with lashings and lashings of dependencies
  - name: repo
    type: git
    source: &repo-source # apply a YAML anchor so we can refer to this in the cache resource
      uri: https://github.com/ymedlop/npm-cache-resource.git
      branch: npm-package-example

  # a resource caching the dependencies listed in the source repository
  - name: npm-repo-cache
    type: npm-cache # as defined above
    source:
      <<: *repo-source # the source is the same as the corresponding git resource ...
      paths: # ... except that it's only interested in files listing dependencies
        - package.json

Behavior

check: Check for new commits

The repository is cloned (or pulled if already present), and any commits from the given version on are returned. If no version is given, the ref for HEAD is returned.

Any commits that contain the string [ci skip] will be ignored. This allows you to commit to your repository without triggering a new version.

in: Pulls a package from npm

Clones the repository to the destination, and locks it down to a given ref. It will return the same given ref as version. And fetch npm package from the package.json`.
