auth0-rule-as-action

Run an Auth0 Rule as an Action

📦 NPM: https://www.npmjs.com/package/auth0-rule-as-action

Experimental

This is an experiment with a very small feature set.

Example

Add as dependency to a Post Login action

auth0-rule-as-action@latest

Example Post Login action

const RuleToAction = require("auth0-rule-as-action");

/**
 * The Rule
 */
function accessOnWeekdaysOnly(user, context, callback) {
  if (context.clientName === 'All Applications') {
    const date = new Date();
    const d = date.getDay();

    if (d === 0 || d === 6) {
      return callback(
        new UnauthorizedError('This app is available during the week')
      );
    }
  }

  callback(null, user, context);
}

/**
 * Handler that will be called during the execution of a PostLogin flow.
 *
 * @param {Event} event - Details about the user and the context in which they are logging in.
 * @param {PostLoginAPI} api - Interface whose methods can be used to change the behavior of the login.
 */
exports.onExecutePostLogin = async (event, api) => {
  const rule = accessOnWeekdaysOnly;
  await RuleToAction.convert(event, api, rule);
};

Options

Pass in custom methods for conversion process.

await RuleToAction.convert(event, api, rule, {
  // Rule callback() method
  callback: RuleToAction.defaultRuleCallback,
  // Maps Post-Login action Event variables to Rules Context variables 
  mapEventToContext: RuleToAction.mapEventToContext
});

Currently supported features

-context.idToken["claim"] = "value";
+api.idToken.setCustomClaim(claim, value);

-context.accessToken["claim"] = "value";
