Goal/MVP: Build a Service in Golang to set meetup times and to track attendance with basic auth.

Extensions:

• Deployable in AWS
• Register User flow
• SMS/Email Notification/Reminder Service
• Some cURL samples for usage

Lets build a meetup planner and attendance management service

1. Firstly we will need a crud service to manage meetups, so meetups are the initial data object
2. Users should be able to create a meeting at a date time with a list of attendee usernames
3. users will be basic auth (ext), mvp can be hardcoded

Architecture

TODO: Pretty Picture

Development

Run unit tests and compile code locally with.

make meetup-service

Directories

** to be refactored...template for the moment **

• $/cmd/service - service entry point
• $/openapi - house OpenAPI spec document(s) for the service
• $/mocks - top-level mocks package for generated mocks
• $/sam - contain AWS infra Serverless Application Model (SAM) template
• $/internal/api - main API entry point, and contains API route handlers, the code that handles API requests
• $/internal/app - stores build-time information and information about this app
• $/internal/flags - initialise application config and command line arguments
• $/internal/openapi - (optional) contains generated code from OpenAPI spec; mainly there to not cause circular package dependency as persistence package also reference genrated code in this example
• $/internal/persistence - (optional) contains code that persists models to a storage location
• $/internal/requestvalidation - contains custom validation config that skips validation of security schemes defined in OpenAPI spec as it's not compatible with AWS SigV4 scheme
• $/internal/router - creates an instance of Echo router and register all required middlewares
• $/internal/ssmcache - (optional) example usage of SSM client with caching

CI/CD

To be added

Mocks

The service uses gomock to generate mocks at build time. for auto generated mocks

Generating mocks for tests, or applying updates to them is as follows:

make generate
