Developing locally

TL;DR

cp settings.sample.yaml settings.yaml
go run ./cmd/synthetic-wallet-instance

To run the project

go run ./cmd/synthetic-wallet-instance

1. Create a settings file by copying the sample

   cp settings.sample.yaml settings.yaml

   Adjust these as necessary. The sample file should have what you need for local development. (Make sure you do this step each time you run git pull in case there have been any changes to the sample settings file.)

2. You are now ready to run the application:

   go run ./cmd/synthetic-wallet-instance
    ```
   > If you get a port conflict, you can find the existing process using the port with, e.g., `lsof -i :<Your_Port_Number_Here>` or simply kill whatever is on the port with `npx kill-port --port <Port_Number>`.

Authenticating

One of the variables set in settings.yaml is JWT_KEY_SET_URL. By default this is set to http://127.0.0.1:5556/dex/keys. To make use of this, clone the DIMO Dex fork:

git clone git@github.com:DIMO-Network/dex.git
cd dex
make build examples
./bin/dex serve examples/config-dev.yaml

This will start up the Dex identity server on port 5556. Next, start up the example interface by running

./bin/example-app

You can reach this on port 5555. The "Log in with Example" option is probably the easiest. This will give you an ID token you can provide to the API.

Linting

brew install golangci-lint

golangci-lint run

This should use the settings from .golangci.yml, which you can override.

Mocks

To regenerate a mock, you can use go gen since the files that are mocked have a //go:generate mockgen ... at the top. For example: nhtsa_api_service.go

API

Protocol buffers

If you make changes to any of the .proto files in pkg/grpc, regenerate the Go code by running make gen-proto.
