Also, as an open platform, there is freedom from vendor lock in as you can replicate your workflow to many providers. You can get under the hood and see how an application is hosted. It has a introductory free trial and is incredibly efficient for running Node applications! As Node and Express are open source projects, there is consistency with working with an open deployment platform such as Cloud Foundry. It is a polyglot platform supporting many different languages including Node.js, Java, PHP, Python, Staticfiles and Ruby. Pivotal Web Services is a public instance of the Open Source Cloud Foundry Platform. Before we get started, let’s cover some of the reasons why PWS is ideal for Node.js apps. This section provides a practical demonstration of how to deploy the LocalLibrary sample application on the Pivotal Web Services PaaS cloud. You have two options, you can go through the tutorial from the Deploying LocalLibrary on PWS how to look at logs, again using the cf CLI tool.how to set environment variables for Node using the cf CLI.use the cf CLI tool to create a new mongoDB service instance and bind it to the local library application.using the cfenv module to connect to a MongoDB instance from mLab that was created and bound using the PWS marketplace.adding and installing the ‘cfenv’ node module to make working with services easier.Configuring the package.json file to run with the engines available on PWS.In doing so, it covers the basics of deploying any node.js application to PWS with the following steps. This post covers how to modify the LocalLibrary application from the tutorial for deployment on PWS and Cloud Foundry. (It uses some other popular non-Open Source PaaS) What it does not tell you is how to deploy that same tutorial to PWS. In this multi-part tutorial, you learn about how to install and configure node locally, how to create a simple database driven application using MongoDB and how to deploy it to production. A solid introduction to node.js and the popular Express framework is from the Mozilla foundation. Node.js is one of the most popular runtime environments on Pivotal Web Services (PWS). Introduction to Node on Pivotal Web Services To do that, go to web>resources and in the index.html file, replace the content with the following code:Ĭallback(jqXHR.getResponseHeader('x-csrf-token')) Update the UI to be able to send POST requests. For HTTP POST requests, they need to have the Update scope assigned. To check the full list of methods and properties of the security context, see: Authentication for Node.js ApplicationsĪs defined in the start.js file, for HTTP GET requests users need the Display scope to be authorized. The resulting request object is initialized with the incoming JWT token. To every request object, using passport and xssec.JWTStrategy, a security context is attached as an authInfo object. IMPORTANT: Authorization checks are enforced by the xssec package in the directory. Var isAuthorized = ('$XSAPPNAME.Display') Ĭonst isAuthorized = ('$XSAPPNAME.Update') Ĭonsole.log('myapp listening on port ' + port) To do that, refresh its previously loaded URL in a web browser – you should get a response 401 Unauthorized.Ĭonst bodyParser = require('body-parser') Ĭonst xsenv = JWTStrategy = users = require('./users.json') Ĭonst services = xsenv.getServices()) The browser window displays Application user:, showing the email you have used for your Cloud Foundry logon.Ĭheck that the myapp application is not accessible without authentication. In this scenario, the authentication is handled by XSUAA through the application router.Ĭlick the My Node.js Application link. Open a new browser tab or window, and enter the generated URL of the web application.Įnter the credentials for your SAP BTP user.īoth the myapp and web applications are bound to the same Authorization and Trust Management (XSUAA) service instance nodeuaa. When the staging and deployment steps are completed, the web application should be successfully started and its details displayed in the command console. It will then forward the requests to the myapp application. What’s going on?Īt this point of the tutorial, the URL of the web application will be requested instead of the myapp URL. This command will update the myapp application and deploy the web application.
