LTV GraphQL Proof-of-Concept

This is a barebones proof-of-concept of a possible GraphQL implementation that interacts with Core. It includes a few very basic (incomplete) types to show how the GraphQL service may be a liason between mobile apps and the backend.

Files to read

In particular, you should check out:

• graphql_resolvers.go: definitions and explanations for resolver functions.
• graphql_schema.go: Definition of the GraphQL schema, along with types and their associated fields.

Authentication

In a production setup, we would have nginx route the /graphql URL to this service; we could then use the session information from the client request to authenticate with Core. In this setup, we'll need to do some manual work to simulate that setup.

1. Login to production Core on a web browser.
2. In the browser developer tools, copy the value of the "Cookie" header. Copy only the value, not the name.
3. Paste the cookie into a file named cookie.txt within this directory. Make sure that the file does not include a trailing newline.

Setup

Once you've followed the Authentication instructions above, you can get this started with:

docker-compose up

Then navigate to localhost:8080 in your web browser; you'll get a form where you may enter queries and see how they'll be returned to mobile clients.

Notes

• Errors are almost entirely ignored; this is a PoC, not production ready!
• The available types are reports and basic information about the logged-in user. This is far from complete, but is meant to show a big-picture view of GraphQL in action.
