CVR View

The easy open source way to privately host your code coverage.

line cvr

CVR View is an Express application for hosting your code coverage results. If you'd like to host your coverage internally, or without paying for monthly services, CVR View might be for you.

To get started, using the seed project is recommended to make your future updating as simple as a new npm install.

Configuration

Configuration requires some setup and copying of related details into environment variables on the machine hosting Node.js:

  • Create a GitHub Application
  • Host a MongoDB Instance
  • Host CVR on Node.js
  • Expose a domain name to the hosted instance

Required Environment Variables

The required configuration information is for GitHub OAuth and the MongoDB connection string. This info can be specified in either a .env file in the project root, or via environment variables. A .env-sample file is included that you can fill out and rename as .env.

If required variables are missing a crash will occur.

  • GITHUB_CLIENTID GitHub OAuth Client ID
  • GITHUB_CLIENTSECRET GitHub OAuth Client Secret
  • GITHUB_CALLBACKURL GitHub OAuth Callback URL
  • DB_CONN MongoDB Connection String
  • HOST The host the server will run on

Optional Environment Variables

  • GITHUB_ORGS_WHITELIST Optional array of allowed GitHub orgs. If empty or omitted, all orgs are allowed.
  • MAX_REPO_COMMIT_HISTORY By default only the last 20 commits per repo are saved to conserve storage space.

Create a GitHub Application

A GitHub application must be created through GitHub.com to give access to repos in your organization. It is not recommended to make the application on this page https://github.com/settings/applications/new but if you select the relevant organization from the bottom left of the page and then select Applications on the left, you can make the application under the organization's account.

  • Application name can be anything you recognize, cvr will do.
  • Homepage URL should be the address where you are hosting your CVR server, maybe something like https://cvr.domain.com.
  • Authorization Callback URL should be the domain above with the added path /auth/github/callback, so with our example that would be https://cvr.domain.io/auth/github/callback. This is the same URL to use for the environment variable GITHUB_CALLBACKURL
  • Save the settings and grab the Client ID and Client Secret from the top right of the page for use with the corresponding environment variables.

Host a MongoDB Instance

If you are not familiar with hosting MongoDB, using a service like MongoLab is recommended. Once you create an instance and user, grab the connection string, which is a URL, and assign it to the DB_CONN environment variable. This URL starts with mongodb://.

Host CVR on Node.js

Running the service with something like Forever that provides automatic restarts is recommended. For example:

  • npm install
  • npm install forever -g
  • forever start bin/www

Expose a Domain Name to the Hosted Instance

The application will need to be hosted under a domain that matches the one you entered when creating the GitHub application. This needs to be configured at the DNS level, generally as a CNAME.
