Package Exports

api-spec-converter

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (api-spec-converter) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

source - Filename or URL for the source

Simple example:

var Converter = require('api-spec-converter');

Converter.convert({

Callback vs Promises

This library has full support for both callback and promises. All async functions return promises but also will execute callback if provided.

var Converter = require('api-spec-converter');

Converter.convert({
  from: 'swagger_1',
  to: 'swagger_2',
  source: 'https://api.gettyimages.com/swagger/api-docs',
})
.then(function(converted) {
  console.log(converted.stringify());
});

Advanced features:

var Converter = require('api-spec-converter');
Converter.convert({
  from: 'swagger_1',
  to: 'swagger_2',
  source: 'https://api.gettyimages.com/swagger/api-docs',
})
  .then(function(converted) {
    // [Optional] Fill missing fields with dummy values
    converted.fillMissing();

    // [Optional] Validate converted spec
    return converted.validate()
      .then(function (result) {
        if (result.errors)
          return console.error(JSON.stringify(errors, null, 2));
        if (result.warnings)
          return console.error(JSON.stringify(warnings, null, 2));

        console.log(converted.stringify());
        FS.writeFileSync('swagger2.json', converted.stringify());
      });
