Services Auth

@labshare/services-auth is a plugin that integrates with @labshare/services to provide Socket.io and Express.js API Resource Scope authorization with RS256 JWT validation.

Install

npm i @labshare/services-auth --save

Options

• authUrl (String) - The base URL for a remote LabShare Auth service. Example: https://a.labshare.org/_api. Required.
• organization (String) - The LabShare Auth organization ID the API service is registered to. Required if secretProvider is not specified.
• audience (String) - An optional API service identifier registered to the LabShare Auth service. This is used for JWT audience validation.
• issuer (String) - Optional value for validating the JWT issuer (the iss claim).
• secretProvider (Function) - An optional, custom function for obtaining the signing certificate for RS256. The signature is (req, header: {alg: string}, payload, cb: (error: Error, signingCert: string) => void): void.

Usage

This example demonstrates scope-based authorization for an HTTP API module using @labshare/services to load the route definition. With the configuration below, only JWTs containing an audience of https://my.api.identifier/resource and a read:users scope would be allowed to access the API route. Additionally, the JWT would be validated using the JSON Web Key Set of the specified organization.

// api/users.js

module.exports = {
    routes: [
        {
            path: '/users',
            httpMethod: 'GET',
            middleware: getUsers,
            scope: [
                'read:users'
            ]
        }
    ]
}

// lib/index.js

const {Services} = require('@labshare/services'),
    servicesAuth = require('@labshare/services-auth');

const services = new Services(/* options */);

// Adds scope-based route authentication and authorization to LabShare Service routes and sockets
services.config(servicesAuth({
    authUrl: 'https://ls.auth.io/_api',
    audience: 'https://my.api.identifier/resource',
    issuer: 'LabShare Auth',
    organization: 'my-org'
}));

services.start();
