Pingster Server

API and scheduled Pingster test runner for your GitHub projects.

Usage

Clone this repository and run your own instance of Pingster server:

npm install
npm start

# or for development
npm run watch

Endpoints

• GET /auth/github - login user with GitHub OAuth flow
• GET /auth/github/callback - GitHub OAuth callback URL
• GET /list (requires GitHub user access token in privateAccess) - list last run repositories test results
• POST /rescan (requires GitHub user access token in privateAccess) - force rescan of the repositories and re-run the tests

List response example

Here is example response from GET /list endpoint. It could be useful if you'd like to create your own UI for showing test results (instead of pingster-ui)

  // list of user/org repos with pingster config 
  "repos": [{

  }],

Configuration

Most of the options are self-descriptive (configuration is powered by c0nfig module):

module.exports = {
  port: process.env.NODE_PORT || process.env.PORT || 1985,
  
  // set to `true` if you want to validate user has proper access to repos
  privateAccess: false,

  scanInterval: 1000 * 60 * 60, // msecs (1 hour)
  scanOnServerStart: true,
  scanPersistenDriver: 'memory',

  github: {
    // github organization to scan (higher priority)
    org: process.env.GITHUB_ORG,

    // or github user to scan
    user: process.env.GITHUB_USER,

    // api user github authentication
    clientId: process.env.GITHUB_CLIENT_ID,
    clientSecret: process.env.GITHUB_CLIENT_SECRET,

    // organization scanner bot authentication
    // make sure your user-bot has proper access to org
    personalAccessToken: process.env.GITHUB_PERSONAL_ACCESS_TOKEN
  }
};

You can create as many config files as you have Node.js environments, just follow this simple file name rule - {NODE_ENV}.config.js.

Scanner Authorization

Repository scanner uses GitHub OAuth non-web application flow which means that you can simply create a personal token of the user that has access to organization here - https://github.com/settings/tokens and add it to proper configuration file.

User Authorization

Firstly in order to authorize a user you need to register a new GitHub OAuth application here - https://github.com/settings/applications/new.

Please provide Authorization callback URL which in our case will be - https://your.domain/auth/github/callback.

User needs to open https://your.domain/auth/github in the browser and go with GitHub OAuth flow. There's optional redirect_uri param which will be used to redirect the user:

'https://your.domain/auth/github?redirect_uri=https://youranother.domain/application'

// will redirect to =>
'https://youranother.domain/application?access_token=ca9d891fa4bdf7ae5039e689c26370a192422541'

If param is not provided, JSON response will be provided:

{"access_token": "ca9d891fa4bdf7ae5039e689c26370a192422541"}

You need to save access_token in browser's cookies or localStorage and pass it in all requests that require authentication as x-access-token header or access_token query param.

Persistent Drivers

Pingster server comes with several built-in persistency drivers that will save the results of your last test run in order to be able to show this data later.

Though in most cases 'memory' driver will be enough to make the app display correct data but you might want to consider other options as well:

• 'memory' - saves last test results in memory (after server restart data is lost until next rescan)
• 's3' - saves last test results in AWS S3 bucket as one JSON file which is get replaced on every run (you will need to provide aws configuration object in config file)
• 'mongodb' - saves last test results in MongoDB collection as the only document which is get replaced on every run (you will need to provide mongodb configuration object in config file)

More drivers to come and PRs are welcome!

Writing Your Own Driver

You are free to write your own drivers in case you have some specific requirements.

Generally driver should conform to the simple get/set API and here is a boilerplate:

function get () {
  // `get` should always return a Promise
  // even if you are doing sync operation
  return new Promise((resolve, reject) => {

  });
}

// `set` is not returning anything in any case
function set (obj) {

}

module.exports = { get, set };

User Interface

Pingster UI is a single-page app writen in React.js that uses pingser-server to display test results.
