oauth-parameters-registry is a Node.js module that provides a registry of OAuth parameters. The registry is based on the IANA OAuth Parameters Registry, which is a registry of parameters registered in the OAuth protocol with IANA. The module provides a simple API for accessing the registry, including methods for getting the name of the registry, the metadata of the registry, a specific parameter by name, and all parameters in the registry.

All of the underlying JSON that supports this lib is generated over at the iana-registry-data-lib project, which can be found here at iana-registry-data-lib.

// Make an instance
const { OAuthParametersRegistry } = require('oauth-parameters-registry');

const oauthRegistry = new OAuthParametersRegistry();

// Get the name of the registry
const name = oauthRegistry.getName();

// Get the metadata of the registry
const metadata = oauthRegistry.getMetadata();

// Get a specific parameter by name
const parameter = oauthRegistry.getParameter('authorization_details');

// Get all parameters of the registry
const parameters = oauthRegistry.getParameters();
