Swagger 2.0

Development of this toolkit is sponsored by VMware:

Contains an implementation of Swagger 2.0. It knows how to serialize and deserialize swagger specifications.

Swagger is a simple yet powerful representation of your RESTful API.
With the largest ecosystem of API tooling on the planet, thousands of developers are supporting Swagger in almost every modern programming language and deployment environment.

With a Swagger-enabled API, you get interactive documentation, client SDK generation and discoverability. We created Swagger to help fulfill the promise of APIs.

Swagger helps companies like Apigee, Getty Images, Intuit, LivingSocial, McKesson, Microsoft, Morningstar, and PayPal build the best possible services with RESTful APIs. Now in version 2.0, Swagger is more enabling than ever. And it's 100% open source software.

Using 0.5.0

Because 0.5.0 and master have diverged significantly, you should checkout the tag 0.5.0 for go-swagger when you use the currently released version.

Migrating

From 0.5.0 to 0.6.0

You will have to rename some imports:

github.com/go-swagger/go-swagger/httpkit/validate to github.com/go-openapi/validate
github.com/go-swagger/go-swagger/httpkit to github.com/go-openapi/runtime
github.com/naoina/denco to github.com/go-openapi/runtime/middleware/denco
github.com/go-swagger/go-swagger to github.com/go-openapi

Binary distribution

go-swagger is distributed as binaries that are built of signed tags. It is published as github release, rpm, deb and docker image.

Docker image

docker pull quay.io/goswagger/swagger

alias swagger="docker run --rm -it -v $HOME:$HOME -w $(pwd) quay.io/goswagger/swagger"
swagger version

Homebrew/Linuxbrew

brew tap go-swagger/go-swagger
brew install go-swagger

Static binary

You can download a binary for your platform from github:

https://github.com/go-swagger/go-swagger/releases/latest

latestv=$(curl -s https://api.github.com/repos/go-swagger/go-swagger/releases/latest | jq -r .tag_name)
curl -o /usr/local/bin/swagger -L'#' https://github.com/go-swagger/go-swagger/releases/download/$latestv/swagger_$(echo `uname`|tr '[:upper:]' '[:lower:]')_amd64
chmod +x /usr/local/bin/swagger

Debian packages

This repo will work for any debian, the only file it contains gets copied to /usr/bin

echo "deb https://dl.bintray.com/go-swagger/goswagger-debian ubuntu main" | sudo tee -a /etc/apt/sources.list

RPM packages

This repo should work on any distro that wants rpm packages, the only file it contains gets copied to /usr/bin/

wget https://bintray.com/go-swagger/goswagger-rpm/rpm -O bintray-go-swagger-goswagger-rpm.repo

From source

Install or update from source:

go get -u github.com/go-swagger/go-swagger/cmd/swagger

The implementation also provides a number of command line tools to help working with swagger.

Currently there is a spec validator tool:

swagger validate https://raw.githubusercontent.com/swagger-api/swagger-spec/master/examples/v2.0/json/petstore-expanded.json

To generate a server for a swagger spec document:

swagger generate server [-f ./swagger.json] -A [application-name [--principal [principal-name]]

To generate a client for a swagger spec document:

swagger generate client [-f ./swagger.json] -A [application-name [--principal [principal-name]]

To generate a swagger spec document for a go application:

swagger generate spec -o ./swagger.json

Licensing

The toolkit itself is licensed as Apache Software License 2.0. Just like swagger, this does not cover code generated by the toolkit. That code is entirely yours to license however you see fit.

What's inside?

For a V1 I want to have this feature set completed:

• Documentation site

• Play nice with golint, go vet etc.

• An object model that serializes to swagger yaml or json

• A tool to work with swagger:

  • validate a swagger spec document:

  • validate against jsonschema

  • validate extra rules outlined here

    • definition can't declare a property that's already defined by one of its ancestors (Error)
    • definition's ancestor can't be a descendant of the same model (Error)
    • each api path should be non-verbatim (account for path param names) unique per method (Error)
    • each security reference should contain only unique scopes (Warning)
    • each path parameter should correspond to a parameter placeholder and vice versa (Error)
    • path parameter declarations do not allow empty names (/path/{} is not valid) (Error)
    • each definition property listed in the required array must be defined in the properties of the model (Error)
    • each parameter should have a unique name and in combination (Error)
    • each operation should have at most 1 parameter of type body (Error)
    • each operation cannot have both a body parameter and a formData parameter (Error)
    • each operation must have an unique operationId (Error)
    • each reference must point to a valid object (Error)
    • each referencable definition must have references (Warning)
    • every default value that is specified must validate against the schema for that property (Error)
    • every example that is specified must validate against the schema for that property (Error)
    • items property is required for all schemas/definitions of type array (Error)
