Usage

Start using it

  1. Add comments to your API source code, See Declarative Comments Format.
  2. Download Swag for Go by using:
$ go get github.com/swaggo/swag/cmd/swag
  1. The General API annotation lives in actions/app.go, run Swag in your Buffalo project root folder with the flag -g actions/app.go. Swag will parse comments and generate required files(docs folder and docs/doc.go).
$ swag init -g actions/app.go

4.Download buffalo-swagger by using:

$ go get -u github.com/swaggo/buffalo-swagger

And import following in your actions/app.go code, making sure to modify the last package name properly:

import(
    buffaloSwagger "github.com/swaggo/buffalo-swagger"
    "github.com/swaggo/buffalo-swagger/swaggerFiles"
    _ "github.com/<github_name>/<project_name>/docs"
)

Canonical example:

For a complete example take a look at the example directory Below you can find an extract from actions/app.go

package actions

import(
    buffaloSwagger "github.com/swaggo/buffalo-swagger"
    "github.com/swaggo/buffalo-swagger/swaggerFiles"
