Callisto

Callisto (formerly BDJuno) is the Juno implementation for Big Dipper.

It extends the custom Juno behavior by adding different handlers and custom operations to make it easier for Big Dipper showing the data inside the UI.

All the chains' data that are queried from the RPC and gRPC endpoints are stored inside a PostgreSQL database on top of which GraphQL APIs can then be created using Hasura.

Usage

To know how to setup and run Callisto, please refer to the docs website.

Testing

If you want to test the code, you can do so by running

$ make test-unit

Note: Requires Docker.

This will:

1. Create a Docker container running a PostgreSQL database.
2. Run all the tests using that database as support.

Setup

Remember to run this if you have an empty database:

cd hasura
hasura metadata apply --endpoint http://localhost:8080 --admin-secret myadminsecretkey
