qa-deployer -- Deploy a package to a hosting service for easy review

This package is used to easily deploy the contents of the current directory to an external service, and then optionally send one or more deployment notification.

The easiest way to use this package is with a CLI script (or writing your own). The module is used by specifying a deployer and notifiers:

var qa_deployer = require('qa-deployer');

qa_deployer.deploy({
  deployer: {
    service: 'modulus',
    auth: {username: 'me', password: '12345'},
    project: 'my-new-feature'
  },
  notifiers: [{
    service: 'github-pull-request',
    auth: {user: 'me', pass: '12345'},
    owner: 'SparkartGroupInc',
    repo: 'qa-deployer',
    pull_request: 1,
    comment: function(review_url) {
      return 'Ready for review at ' + review_url;
    }
  }]
});

Available Deployers

modulus

Deploys the current package to Modulus.

Usage

• auth - An object with the Modulus account's username and password.

• include_modules - Whether to upload the node_modules folder. Optional, defaults to false.
• env - An object with environment variables and their values to be set in the Modulus environment.

s3-static-website

Deploys the current directory to Amazon S3 as a static website.

Usage

• s3_options - An object used to configure the connection to S3. See the AWS.S3 documentation.
• bucket_name - The S3 bucket where to upload the files. If the bucket is missing, it will be automatically created and configured to host the static website. Optional, defaults to the current directory name.
• region - The AWS region where the site will be hosted. Optional, defaults to us-east-1.
• removeExtensions - List of extensions to remove from uploaded files, for example ['.html', '.htm']. Optional.

Available Notifiers

github-pull-request

Adds a comment to the specified GitHub pull request with the deployed URL.

Usage

• auth - An object with the GitHub account's user and pass. The pass is a token which needs to have access to either the repo or public_repo scopes.
• owner - The owner of the repo containing the pull request to comment on.
• repo - The repo containing the pull request to comment on.
• pull_request - The pull request number to comment on.
• notify_redeploys - Whether to notify after the first deploy to the deployer service. Optional, defaults to false.
• comment - A function called with the review_url as an argument, that returns the comment to add. Optional.

webhook

POSTs the deployed URL to a webhook URL, as JSON.

Usage

• url - The webhook URL to POST to.
• notify_redeploys - Whether to notify after the first deploy to the deployer service. Optional, defaults to false.
• method - HTTP method to use: get, post or put. Optional, defaults to post.
• headers - Object of HTTP headers to add to the request. Optional.
• body - A function called with the review_url as an argument, that returns the JavaScript object to POST. Optional, defaults to {review_url: <review_url>}.

Available Scripts

circleci-deploy

Called by CircleCI, it automatically deploys a branch when a commit is made.

The following deployers are supported, with some usage changes:

• modulus
• project - Defaults to the GitHub branch, unless it is master.
• s3-static-website
• bucket_name - Defaults to the GitHub organization, repository and branch ([organization]-[repository]-[branch]), unless the branch is master.

Notifiers can be enabled by adding an options file. This JSON formatted file can contain deployer and notifier options, similar to the module usage above. For example:

{
  "deployer": {
    "service": "modulus",
    "include_modules": true,
    "env": {
      "NPM_AUTH_TOKEN": "sample-token-value"
    }
  },
  "notifiers": [
    {"service": "github-pull-request"},
    {"service": "webhook", "url": "http://my-webhook", "notify_redeploys": true}
  ]
}

The file can also be a Node module:

module.exports = {
  deployer: {
    service: 'modulus',
    include_modules: true
  },
  notifiers: [
    {service: 'github-pull-request'},
    {service: 'webhook', url: 'http://my-webhook', notify_redeploys: true}
  ]
};

Usage

Required environment variables:

• GITHUB_USER
• GITHUB_PASS

With the modulus deployer:

• MODULUS_USERNAME
• MODULUS_PASSWORD

With the s3-static-website deployer:

• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY

Command line options:

• --deployer=SERVICE - The deployer to use. Optional, can also be set from the options file.
• --options-from=FILE - Read additional options from FILE.

Example circle.yml configuration file:

dependencies:
  post:
    - npm install qa-deployer -g
deployment:
  production:
    branch: master
    commands:
      - circleci-deploy --options-from=production-deployer.json

circleci-deploy-github-pull-request

Similar to the circleci-deploy script, but will only deploy when an open GitHub pull request exists for the current branch. If not, the branch will not be deployed, and will be withdrawn from the deployer service instead.

Note: CircleCI will only trigger new builds when a commit is made to an existing pull request. To deploy a branch when a pull request is created (without pushing an extra commit), the CircleCI API needs to be called. On way to automatically do this is to create a PullRequestEvent Webhook in the GitHub project's settings. This Webhook will POST to a relay service, such as Zapier, which will in turn POST to the appropriate CircleCI API URL.

Example circle.yml configuration file:

dependencies:
  post:
    - npm install qa-deployer -g
deployment:
  qa:
    branch: /^(?!master$)(.+)/
    commands:
      - circleci-deploy-github-pull-request --options-from=qa-deployer.json

circleci-withdraw-closed-github-pull-requests

The circleci-deploy-github-pull-request script withdraws the current branch from the deployer service when its corresponding GitHub pull request is closed. Unfortunately, CircleCI does not run a build when a branch is deleted, so the withdrawal never happens when a GitHub pull request is closed and its branch is deleted at the same time.

This script takes care of that missed cleanup: it retrieves a list of all closed GitHub pull requests, and withdraws all matching projects from the deployer service.

Example circle.yml configuration file, to cleanup old projects whenever commits are made to master:

dependencies:
  post:
    - npm install qa-deployer -g
deployment:
  production:
    branch: master
    commands:
      - circleci-deploy --options-from=production-deployer.json
      - circleci-withdraw-closed-github-pull-requests --options-from=production-deployer.json
