ipld-ethcl-indexer

This application will capture all the BeaconState's and SignedBeaconBlock's from the consensus chain on Ethereum. This application is going to connect to the lighthouse client, but hypothetically speaking, it should be interchangeable with any eth2 beacon node.

To learn more about the applications individual components, please read the application components.

Running the Application

To run the application, utilize the following command, and update the values as needed.

go run main.go capture head --db.address localhost \
  --db.password password \
  --db.port 8077 \
  --db.username vdbm \
  --db.name vulcanize_testing \
  --db.driver PGX \
  --bc.address localhost \
  --bc.port 5052 \
  --log.level info

Development Patterns

This section will cover some generic development patterns utilizes.

Logging

For logging, please keep the following in mind:

• Utilize logrus.
• Use log.Debug to highlight that you are about to do something.
• Use log.Info-Fatal when the thing you were about to do has been completed, along with the result.

log.Debug("Adding 1 + 2")
a := 1 + 2
log.Info("1 + 2 successfully Added, outcome is: ", a)

• loghelper.LogError(err) is a pretty wrapper to output errors.

Testing

This project utilizes ginkgo for testing. A few notes on testing:

• All tests within this code base will test public methods only.
• All test packages are named {base_package}_test. This ensures we only test the public methods.
• If there is a need to test a private method, please include why in the testing file.

Contribution

If you want to contribute please make sure you do the following:

• Create a Github issue before starting your work.
• Follow the branching structure.
• Delete your branch once it has been merged.
  • Do not delete the develop branch. We can add branch protection once we make the branch public.

Branching Structure

The branching structure is as follows: main <-- develop <-- your-branch.

It is adviced that your-branch follows the following structure: {type}/{issue-number}-{description}.

• type - This can be anything identifying the reason for this PR, for example: bug, feature, release.
• issue-number - This is the issue number of the GitHub issue. It will help users easily find a full description of the issue you are trying to solve.
• description - A few words to identify your issue.
