• Go

• Docker (optional) - for running the database

• Make (optional) - for running the Makefile commands (shortcuts for other commands)

• Air (optional) - for hot reloading while developing

• Ginkgo (optional) - for running the tests

1. Clone the repository

git clone

2. Install dependencies

go mod download

3. Create a .env file in the root of the project by copying the .env.example file and filling in the correct values

cp .env.example .env

4. Run the migrations

make migrate-up

5. Generate the TEMPL files

templ generate

5. Run the server

make run
# or (if you have Air installed)
air

TEMPL

Because the BodyParser will default parse null string fields as empty strings, we need a better solution to get actual null values With the omitempty tag, we also won't get the desired result, because it will omit the field if it's null (and then use the default value - empty string)

The solution is to use the packages "gopkg.in/guregu/null.v4/zero" and "gopkg.in/guregu/null.v4/null" And then use the types zero.String and null.String instead of string

Because these will use a struct under the hood, we also want to overwrite the swagger documentation for these fields, so that it will show the correct type in the docs with swaggertype:"string" tag

We use Atlas for schema based migrations. Because we use GORM as our ORM, we can use the https://atlasgo.io/guides/orms/gorm package to generate migrations directly from our models. The configuration for this happens in atlas.hcl and loader/atlasGorm.go

We wrap the most common Atlas commands in the Makefile, so that we can easily run them. The commands are:

# Generate a new migration file based on the current models
make migrate-gen name=<migration-name>

# Generate a new empty migration file
make migrate-new name=<migration-name>

# Apply all migrations up to the latest version
make migrate-up

# Reverse all migrations down to the given version (version is the timestamp of the migration file)
make migrate-down version=<version>
