Aaron Chambers and me gave detailed walkthroughs of the basic ideas behind the pipeline at the Ember-London and Ember.js-Munich meetups respectively.

The new release encourages heavy use of deploy plugins that all implement different parts of a deployment via hooks and are themselves Ember CLI addons. What wasn’t available though was a plugin for notifying external webservices (e.g. an error-tracking service) during or after deployments so we decided to write one.

anchorIntroducing ember-cli-deploy-notifications

ember-cli-deploy-notifications makes it easy to notify external services by adding them to a notifications.services.<service> property in config/deploy.js. First you have to install the addon:

ember install ember-cli-deploy-notifications

The second step is to configure the services that you want to notify while executing the deployment pipeline.


// config/deploy.js
module.exports = function (deployTarget) {
  var ENV = {
    // ...

    notifications: {
      services: {
        bugsnag: {
          didActivate: {
            apiKey: '',
          },
        },
      },
    },
  };

  return ENV;
};

Every time a new revision gets activated now by ember-cli-deploy, ember-cli-deploy-notifications will sent a POST request to the bugsnag service to notify it of the newly activated deployment revision.

anchorCustomization

We figured out that there are a lot of different internal and external services that users of ember-cli-deploy wanted to notify when executing the deploy pipeline. Thus we wanted to make ember-cli-deploy-notifications as flexible as possible but still keep things easy and simple for the most basic use cases.

Based on that assumption we came up with the idea of "preconfigured" and "custom" services.

anchorCustom services

Services need to be configured with values for url, headers, method and body. We figured out that these are all the necessary parts of a webservice request that you need to be able to customize.

Additionally you need to provide a property named the same as the hook that you want the service to be notified on when running through the deploy pipeline (as we wouldn’t know when to notify a service otherwise):


// config/deploy.js
module.exports = function (deployTarget) {
  var ENV = {
    // ...

    notifications: {
      services: {
        mainmatter: {
          url: 'https://notify.mainmatter.com/deploy',
          headers: {},
          method: 'POST',
          body: function (context) {
            var deployer = context.deployer;

            return {
              secret: 'supersecret',
              deployer: deployer,
            };
          },
          didActivate: true,
        },
      },
    },
  };

  return ENV;
};

url, headers, method and body are the basic ideas behind the service abstraction in ember-cli-deploy-notifications but to keep things simple you don’t have to provide headers and method for every custom service as these properties will default to {} and 'POST' respectively.

As you can see service configuration properties can either be defined directly or generated dynamically based on the deployment context. this will always point to the service’s configuration itself in all of these functions which enables you to do things like this:


// config/deploy.js
module.exports = function(deployTarget) {
  var ENV = {
    // ...

    notifications: {
      services: {
        slack: {
          webhookURL: ''
          url: function() {
            return this.webhookURL;
          },
          body: {
            text: 'A new revision was deployed!'
          },
          didActivate: true
        }
      }
    }
  };

  return ENV;
};

The configuration properties named the same as ember-cli-deploy’s pipeline-hooks can also be used to override configuration defaults on a per hook basis:


// config/deploy.js
module.exports = function (deployTarget) {
  var ENV = {
    // ...

    notifications: {
      services: {
        slack: {
          url: '',
          body: {
            text: 'A new revision was deployed!',
          },
          didActivate: true,
          didFail: {
            body: {
              text: 'Deployment failed!',
            },
          },
        },
      },
    },
  };

  return ENV;
};

anchorPreconfigured services

As we wanted to make it as easy as possible to get started with ember-cli-deploy-notifications there are already some preconfigured services.

Preconfigured services differ from custom services in the fact that the community has already provided a default configuration for these services. For example the popular error tracking service bugsnag is already preconfigured which makes it easy to use out of the box with ember-cli-deploy-notifications:


// config/deploy.js
module.exports = function (deployTarget) {
  var ENV = {
    // ...

    notifications: {
      services: {
        bugsnag: {
          apiKey: '',
          didActivate: true,
        },
      },
    },
  };

  return ENV;
};

There is also a preconfigured service for slack.

anchorNext Steps

We are excited to share this small ember-cli-deploy plugin with the ember community and would like to hear your feedback! We are already using it in client projects and, though pretty small, found it to be a very useful addition to our deployment workflow.

Please refer to the project’s README for more detailed information about the plugin and don’t hesitate to open issues or ask questions, we’re happy to support you in setting up a great deployment workflow for your Ember applications.
