Steamer

Command line tool for Vapor stub (template) server generator from the OpenAPI (Swagger) specification written in Swift.

Targeted supported versions:

• Vapor 3
• OpenAPI 3.0.* (Current latest - 3.0.1 Spec)

Concept

The OpenAPI definition of API design is a great base that could allow to create autogenerated code that:

• Would be well-documented - as the OpenAPI definition by itself ideally should be a 'documentation' for client developers it could be automatically brought to the Swift code definitions.
• Would share the generated Models and Request/Response code as much as possible between the RESTful server and client application which automatically would ensure serialisation of data passed between server and client is SAME:
  • No more typos-error debugging of failed requests (e.g. when one side sends 'licence' instead of 'license')
  • No more tricky errors of data types conversions (like Int64 vs Int32, the Date formats, etc.)
  • Shared models would be a SINGLE place you need to change if required
• Would be extensible, ideally allowing incremental updates of code from the updated OpenAPI definition with minimal impact on manually added code.
• Would be simple and Swifty, created so that thoughts like 'it would be easier to delete and rewrite it' should never appear in developer head when he sees it.

Goals

• Encourage the API design first if it suits your needs!
• Make implementation and prototyping of RESTful servers using Vapor event more easier by minimising boilerplate coding
• Meet incredible and amazing Swift professionals who would like to join and contribute to this project! :)

Features - TBD, starting list to think of...

• Generation of stubbed API server from OpenAPI document:
  • Models
  • Controllers
  • Routing
  • everything else needed to run
• Use Security Scheme definitions for authorization and authentification support
• Mock responses with data examples if provided
• Comments / documentation generation
• ...

Dependencies (Potential)

• SwaggerParser - Swift library for parsing OpenAPI 2.0 (f.k.a. Swagger) documents into native structures (OpenAPI 3.0 support is "alpha"-ready, currently on fork).
• [?] Yams - A Sweet and Swifty YAML parser.
• [?] Stencil / Leaf or ... - need to choose something for templating.
