Create GraphQL Endpoint To Query Data

[joeyjoejoejr]

After a conversation with @cwmanning about a potential dashboard implementation for an open source version of this app, we realized that the reports that would be useful are specific to teams and companies. Even within viget there seem to be a number of different ways that people would want to consume that information. The new strategy is to open up a graphql api, allowing users to build their own dashboard or reporting mechanisms.

Steps

• Create a graphql endpoint
• Secure the graphql endpoint
• Expose a query for pull requests
• Expose a query for reviews
• Expose a query for users in the system

Discussion

This can be worked on independently of other feature, but securing the graphql endpoint might either need to wait for a system of creating/revoking api tokens.

There are two types of users in the system. There is a github user which is created when an unknown user either creates or reviews a pull-request. There is also a slack user, which is what people will use to log in and change setting/add repositories to cr bot.

Likely we will want to use Juniper:

And use this as a reference for adding GraphQL to Actix
