Swagger Server POC

Swagger Server POC

Step 1: Install go-swagger

• brew tap go-swagger/go-swagger && brew install go-swagger

Step 2: Install dependencies using Glide (install using brew install glide)

glide install

Step 3:

go build main.go

Step 4:

go run main.go

Generating a Server

Resources used to create Swagger YAML that includes definitions and operations:

• Swagger Toolbox - YAML --> JSON

In order to generate a server:

swagger generate server -f ./swagger/swagger.yml

This command will spill out the actions it takes as it generates your new REST server. Do not follow the advice at the end of the output. There’s an alternate mechanism to do so. Just use glide to update dependencies: glide up -v.

Generating the UI

Downloading SwaggerUI files

SwaggerUI can be downloaded from their GitHub Repo. Once downloaded, place the content of dist folder somewhere in your Go project. Then generate the spec:

swagger generate spec -o ./swagger/swagger.json --scan-models

After that, move swagger.json file to swaggerui folder, and inside index.html change url to ./swagger.json (url: "./swagger.json").

The main.go has two go routines that spin up two goroutines - one for each server.

The Swagger UI dist is served using the following logic and handler function:

fs := http.FileServer(http.Dir("./swaggerui"))
http.Handle("/swaggerui/", http.StripPrefix("/swaggerui/", fs))
