A library to process OpenAPI security definitions in parallel.

Highlights

• Easily handle security schemes.
• Performant.
• Extensively tested.
• Small footprint.
• Promise based interface.

Example

See ./test/data-driven/*.js for more examples.

import OpenAPISecurityHandler from 'openapi-security-handler';
const handler = new OpenAPISecurityHandler({
  // these are typically taken from the global api doc
  securityDefinitions: {
    keyScheme: {
      type: 'apiKey',
      name: 'api_key',
      in: 'header'
    },
    passwordScheme: {
      type: 'basic'
    }
  },
  // these handle the operation security reference
  securityHandlers: {
    keyScheme: function(req, scopes, securityDefinition) {
      req.user = {name: 'fred'};
      return true; // could also throw or return a Promise.
    },
    passwordScheme: function(req, scopes, securityDefinition) {
      req.user = {name: 'fred'};
      return true;
    }
  },
  // These are typically defined on an operation's openapi document.
  operationSecurity: [
    // we'll execute all the schemes in the object.  If any fail, we'll move to the
    // next object.
    {
      keyScheme: ['write']
    },
    {
      passwordScheme: ['write']
    }
  ],
});
const request = {};
handler.handle(request).then(result => {
  console.log(result); // => true
});

handler.handle

Return Value

openapi-security-handler#handle returns a Promise.

• If any of the securityHandlers throw an error, the error will be available with .catch.
• If all of the securityHandlers for the given operationSecurity scheme resolve with true, then true will be resolved.
• If none of the securityHandlers resolve with true for all of the operationSecurity schemes, then a 401 error will be thrown.

Successful Authentication

Handlers should assign credentials to the request object.
