OpenAPI-CodeGen

Experimental port of swagger-codegen templates to Node.js. This project was initially a 24-hour hackathon. The model adaptor code is entirely original and has been reverse-engineered from the existing documentation and template usage.

Work in progress

Supports OpenAPI 3.0.x natively, and Swagger/OpenAPI 1.2 and 2.0 by internal conversion

Usage

Installing

npm i -g openapi-codegen

or

• clone the repository, and
• npm i

or

npx -p openapi-codegen cg ...

CLI

cg [options] {[path]configName} {openapi-definition}

Options:
  --help           Show help                                           [boolean]
  --version        Show version number                                 [boolean]
  -d, --debug      Turn on debugging information in the model          [boolean]
  -f, --flat       Do not include config-name in output directory structure
                                                                       [boolean]
  -l, --lint       Lint input definition                               [boolean]
  -o, --output     Specify output directory         [string] [default: "./out/"]
  -s, --stools     Use swagger-tools to validate OpenAPI 2.0 definitions
                                                                       [boolean]
  -t, --templates  Specify templates directory                          [string]
  -v, --verbose    Increase verbosity                                  [boolean]
  -z, --zip        Create a .zip file instead of individual files      [boolean]

e.g.

node cg --verbose nodejs defs/generator.yaml

In this case, the generated code will be written to the .out/nodejs directory.

You can also load the OpenAPI definition from a URL.

If you are using Node 6.x or lower, please specify the --harmony flag.

API

const renderer = require('openapi-codegen');
// load a config and a definition
renderer.main(definition,config,configName);

Templates are taken directly from swagger-codegen. This project is also licensed under Apache-2.0 for this reason. Generated code is explicitly covered by the Unlicense. Code to downconvert OpenAPI 3.0 definitions is taken from Angular-Swagger-UI and is MIT licensed.
