Go Waitlist API

Simple API for double opt-in waitlist signups using Go, Gin, GORM, mariadb and Resend for email sending.

Provides the following endpoints:

• POST /v1/waitlist with JSON body: {"email": "mail@example.com", "additionalInformation": {"firstName": "John"}} (additionalInformation is optional)
• POST /v1/waitlist/opt-in with JSON body: {"email": "mail@example.com", "confirmationToken": "[token provided in email]"}
• POST /v1/waitlist/opt-out with JSON body: {"email": "mail@example.com"}

Setup

1. Clone the repository
2. Copy the .env.sample (cp .env.sample .env) and adjust its contents (please take a look at their usages, a more detailed documentation will be provided soon)
3. Make sure docker (with compose) is installed
4. Build the Go app and image using docker compose build
5. Run the app and DB using docker compose up -d (leave out -d if you don't want it to run in background, e.g. for debugging)

Road Map

• More detailed documentation on setup and environment variables
• Export of registrations to JSON and an authorized admin API endpoint
• Support second email after confirmation
• Support manual email sending without Resend, using SMTP connection
