Migration from 2.x

There are major changes from the 2.x release.

The new swagger-js is almost a drop-in replacement for the 2.x series depending on your style of integration. While effort was put in, to make the transition smooth. This is still a breaking release, and we hope to cover the most common features.

  • Before you start, please verify the minimum requirements to use the library. They have changed.

Specification version

Support for 1.0, 1.1 and 1.2 versions of the Swagger specification have been dropped! You'll need to stick with [email protected] if you need to support those versions. But we encourage updating to OAS 2.0

Promises.

The new swagger-js, uses promises and removes the older style of callbacks. As such creating an instance of SwaggerClient will return a promise.

If you did this:

var client = new SwaggerClient({ success, failure, ...})
function success() {
  client.pet.addPet(...) 
}

You must now do this:

SwaggerClient({...}).then(client => {
  client.pet.addPet(...) 
})

Tags interface

Note, you cannot use tags directly on the Swagger client. You must reference them through the client.apis object. While supported in the 2.x series, this was not the most common method of addressing different operations assigned to a tag.

If you did this:

client.pet
  .findPetById(...)

You must now do this:

client.apis.pet 
  .findPetById(...)

Promises in executors

  • You must use promises rather than success and error callbacks. If your old code looked like this:
client.apis.pet
  .findPetById(
    {petId: 3},
    function(data) { /* success callback */},
    function(error) { /* error callback */ });

you now would call it like such:

client.apis.pet.findPetById({petId: 3})
  .then(function(data) { /* success callback */},
  .catch(function(error) {/* error callback */ }));
  • The parsed response body object in response payloads has a new key name. If you previously did this:
function(response) {
  // print out the parsed object
  console.log(response.obj);
}

You now do this:

function(response) {
  // print out the parsed object
  console.log(response.body);
}

Authorizations

Previously you would add authorizations ( tokens, keys, etc ) as such...

var client = new Swagger('http://petstore.swagger.io/v2/swagger.json', {
  authorizations: {
    my_query_auth: new ApiKeyAuthorization('my-query', 'bar', 'query'),
    my_header_auth: new ApiKeyAuthorization('My-Header', 'bar', 'header'),
    my_basic_auth: new PasswordAuthorization('foo', 'bar'),
    cookie_: new CookieAuthorization('one=two')
  }
})

Or like this...

var client = new Swagger('http://petstore.swagger.io/v2/swagger.json', ...)
// Basic Auth
client.clientAuthorizations.add('my_query_auth', new ApiKeyAuthorization('my-query', 'bar', 'query'))
client.clientAuthorizations.add('my_header_auth', new ApiKeyAuthorization('My-Header', 'bar', 'header'))
client.clientAuthorizations.add('my_basic_auth', new PasswordAuthorization('foo', 'bar'))
client.clientAuthorizations.add('cookie', new CookieAuthorization('one=two'))

Currently you'd use...

NOTE! We're working on changing this to be friendlier to use and to support the config file interface. See: swagger-api#971

Swagger('http://petstore.swagger.io/v2/swagger.json', {
  authorizations: {
    // Type of auth, is inferred from the specification provided 
    my_basic_auth: { username: 'foo', password: 'bar' },
    my_query_auth: 'foo', 
    my_header_auth: 'foo', 
    my_oauth2_token: { token: { access_token: 'abcabc' } },
    cookie_auth: null, // !!Not implemented
  }
}).then( client => ... )

NOTE: Cookie authentication is not implemented.
