Slagora

The goal of this project is to provide a slack application that can be used by teams to create and manage polls directly in slack. Team admins can install the app and Signed in users can then use it to create elections in channels. At the end of every election results are sent to the channel and available to every member of the team.

Use case modeling

I have identified the following tasks in the project at the starting of the project.

  1. Add to slack OAuth2 authentication for teams - Done
  2. Sign in with slack OAuth2 authentication for team members - Done
  3. Users should be able to create election - Done
  4. Users should be able cast their vote - Done
  5. Users should be able to view election details - Done
  6. Users should be able to delete elections. - Done
  7. Users should be able to view results any time if election results are provided in real time - Done
  8. Application should be able to send final results at the end of each election - Done
  9. Application should be able handle the timeline of the Election. Done
  10. User should be able to get help using slash command - Done

Deep view into the technology.

This project is created using play framework 2.6 seeds template.

These are some of the main technologies, we have used in the project.

We started the Google Summer of Code by defining the features that needed to be implemented. After which we created a slack application and added all the setups such as slack command and permissions required by Slagora. After that, we started to work with abstract schema of the models and create controllers to handle actions on those models. Then we started to work with the team and user authentication part. We use silhouette as our authentication library. After which we spent time to configure the Silhouette module and created and OAuth2 implementation for Slack team signup and OAuth2 implementation for slack user sign in still using silhouette. Finally we had to test our implementation with slack API making sure authentication is done correctly.

After that we started working on the election services and models.Then we searched a cloud solution for MongoDB. We use Mlab as our cloud database and found it to be great for development. We used Play2-ReactiveMongoDB to connect to mongoDB in order to store and get our election and user data.

We then created endpoints to receive slash command payloads from Slack. Implemented services to communicated with the Slack API and built interactive messages directly from our application. We created a fully functional system that enables slagora to determine which action the user has taken within slack and take appropriate actions. Some of which are create election, request for help, view election details, vote, request election results, delete election etc.

We created results endpoints to serve the results for finished elections or elections that have support for real-time results. Head over to Slagora to install the application in your team and start creating elections. I discussed a lot with my mentor on each step that was to be taken and he has always helped me with valuable guidance on what is needed.Though Slagora supports various features I can't really say it is production ready since we have to test it with real users and observe how it responds and we have in our roadmap a feature that will enable users communicate directly with Slagora Bot.

We structured the project to ease future development. Created models, view and controllers to ease application development. This will ease the work of new developers, I was greatly helped by mentor in coming up with a simple architecture for the application.
