Server

API

The API is specified with OpenAPI 2.0 in swagger.yml. JetBrains IDEs have excellent support for OpenAPI specifications. For VS Code users, you can consider the Swagger Viewer and OpenAPI (Swagger) Editor extensions.

On the server side, we use go-swagger to automatically generate some boilerplate for the server. Every time swagger.yml changes, one should run make generate to ensure the boilerplate is up to date.

You can view a generated API documentation by running make start and visiting http://localhost:9000/docs.

Installing Go

Common operations

To start the server:

make start

To reformat code:

make format

To regenerate boilerplate code:

make generate

Code organization

Things we can edit:

• impl contains endpoint implementations.
• restapi/configure_down_to_meet.go contains server configurations. Every time we add a new endpoint, we need to add a line to configureAPI that sets the handler appropriately.

Things that are automatically generated, and should not be edited:

• cmd/down-to-meet-server is the generated source code for the server binary.
• models contains the generated data structures.
• restapi (except configure_down_to_meet.go) contains generated server code.
