Installation

From you restlessness project root run:

$ # Install node package
$ npm i @restlessness/auth-cognito
$
$ # Add it to the project using the restlessness cli
$ restlessness add-auth @restlessness/auth-cognito

The add-auth command adds the package to the project and creates an AppUserPoolsManager model class.

Environment variables

The add-auth command also adds parametric environment variables to the .env files present in the project.

Example .env.production file:

RLN_COGNITO_AUTH_USER_POOL_ID=${RLN_COGNITO_AUTH_USER_POOL_ID_PRODUCTION}

Then is possible to set the variable by setting RLN_COGNITO_AUTH_USER_POOL_ID_PRODUCTION or setting RLN_COGNITO_AUTH_USER_POOL_ID directly.

Usage

The add-auth command create a model class implementing the UserPoolsManager class. With this model can be specified the list of pools.

Example:

// src/models/AppUserPoolsManager/index.ts

import { UserPoolsManager } from '@restlessness/auth-cognito';

class AppUserPoolsManager extends UserPoolsManager {
  get poolInfos() {
    return [
      {
        id: 'user',
        attributes: [],
      },
      {
        id: 'my-id',
        attributes: [ 'my' , 'list', 'of', 'attributes' ],
      },
    ];
  }
};

export default new AppUserPoolsManager();

All convenience methods of the UserPoolsManager can be accessed from the extended class:

import userPoolsManager from '../models/AppUserPoolsManager';
// ...
console.log(userPoolsManager.poolInfos)
const userSession = await userPoolsManager.login('sample@email.com', 'sample_password');
// ...

Hooks

The package uses the beforeEndpoint hook to initialize the user pool manager (AppUserPoolsManager).
