Setup

Installing languages and tools required

Install Golang and PostgresSQL. We recommend using a version manager like asdf to manage your installations. Use the versions of the tools listed in the .tool-versions file.

• (For asdf only) if not already installed, install the necessary plugins:

  asdf plugin add golang
  asdf plugin add postgres

• Install the required versions of the tools:

  asdf install golang 1.21.5
  asdf install postgres 14.8

To work with and debug the API, we also strongly recommend installing tools like Postman.

Setting up git hooks

We use pre-commit and pre-push hooks to ensure that code is formatted and linted before committing and pushing. To set up the hooks, run the following commands:

make hooks

Notes:

• Hooks only work on macOS/Linux. Support for Windows is coming soon.
• You will need to install golangci-lint locally for git hooks to work. See Running linter for instructions.

Setting up the database

Creating the database

Run the following command to create the database:

make db_create

Migrating the database

For this step onwards, make sure you have your environment variables set up correctly. See Setting up environment variables for more details.

Run the migration target to migrate the database:

make db_migrate

By default, the migration target will run all pending migrations (visible using make db_status command). To only run a certain number of migrations forward, use the steps argument:

make db_migrate steps=1

Rolling back migrations

To roll back the most recent migration, run the following command:

make db_rollback

To roll back a certain number of migrations, use the steps argument:

make db_rollback steps=1

Setting up environment variables

Copy .env.example to .env and fill in/modify the required values as needed.

Development

Starting the server

make dev

Running linter

Step 1: Install golangci-lint locally.

Step 2: Run the lint commmand:

make lint

Testing your code

By convention, test files are named *_test.go and are placed in the same directory as the code they are testing.

To run all tests:

make test

To run all tests and view test coverage:

make coverage

Building for production

make build
