This session covers the basics of developing Node.js applications with NetBeans. NetBeans includes fully integrated support for both JavaScript and Node.js. You’ll get a tour of the features and learn how NetBeans can accelerate your projects. The presentation looks at basic code editing capabilities provided by the IDE, tool integration (npm/Grunt/Bower/Webpack), frameworks such as Express, and debugging capabilities. You’ll see why NetBeans is the best free JavaScript/Node.js IDE.

  4. 4. Beating Emacs Problem: Only Java Developers know about NetBeans!
  5. 5. NetBeans Misconceptions Following statements are NOT TRUE: • JavaScript support is secondary • JavaScript integration is just for Java web apps • Projects must be created with NetBeans • Projects must be refactored to use NetBeans • NetBeans can’t deal with framework x and/or build tool y etc. NOT TRUE
  6. 6. Agenda • Overview • Setup • Live Code Examples • Simple Node.js • Node.js + Express • Gulp Integration • Angular & Webpack • Unit Testing • AWS Lambda Testing
  7. 7. Overview
  8. 8. JavaScript Features • Natively supports HTML5 projects. • CSS3, HTML5, ECMAScript 6 & 7 • Support for HTML5 JavaScript libraries. • Features • Syntax highlighting, auto-completion, code folding, etc. • Full-fledged debugger • Breakpoints on DOM, line, event, and XMLHttpRequests. • Call stack, variables, watches • JavaScript unit testing • Grunt Support • SASS/LESS Support • Apache Cordova (mobile HTML5 development)
  9. 9. Supported Frameworks More… Note: Integrated support for Oracle Jet
  10. 10. File Templates Category File Types HTML5/JavaScript HTML File, JavaScript File, CSS, Sass File, Less file, JSON File, react.js, Jade File, package.json, Gruntfile.js, gulpfile.js, bower.json, .bowerrc, JET modules, Knockout JET Module Selenium Tests Protractor Configuration File, Selenium Mocha Test Case, Selenium Jasmine Test Case Unit Tests Karma Configuration File, jsTestDrive Config File Web Services RESTful JavaScript Client Custom editor provided for each file type.
  11. 11. Project Templates
  12. 12. Code Completion
  13. 13. Code Analysis
  14. 14. CSS3 Editing Popup for adding new properties
  15. 15. LESS Support Generated CSS
  16. 16. JavaScript Debugging + Chrome
  17. 17. DOM Debugging
  18. 18. Customizable Palette • Drag HTML elements from Palette into HTML Window (Wizard appears) • Drag selections from HTML document to Palette to create new HTML snippets.
  19. 19. Dependency Management Three different approaches: • npm • Bower • CDNJS
  20. 20. Gulp Integration
  21. 21. Gulp Integration
  22. 22. Node.js Integration • Fully integrated support for Node.js • Node.js project wizard • Search/find Node modules • Integrated support Express generator • Project specific Node.js settings
  23. 23. Setup
  24. 24. NetBeans Setup 1. Install Node.js 2. Download Sources 3. Setup npm/express
  25. 25. Install Chrome Plugin https://goo.gl/Jc9Tq4
  26. 26. Configure Runtime Environment Select Browser to use for testing – project specific. Note testing on connected devices.
  27. 27. Angular / TypeScript Support Download plugin: https://github.com/Everlaw/nbts/
  28. 28. Angular / TypeScript Support Install via Plugin Manager
  29. 29. Deep Dive
  30. 30. Typical Workflow npm init Edit package.json npm install NetBeans performs these tasks for us. Shell commands can be executed at any point – not locked into the IDE.
  31. 31. Demos • Simple Node.js application & debugging • Node.js + Express • Gulp Demo • Angular 4 Demo with TypeScript & Webpack • https://github.com/angular/angular2-seed
  32. 32. Unit Testing
  33. 33. Unit Testing • Supported Unit Testing frameworks: • Karma • JS Test Driver • Mocha • Demo • Jasmine – JavaScript unit testing framework • Tests written in JavaScript • Test synchronous and asychronous JavaScript code • Karma – JavaScript test runner • Based on NodeJS • Launches and executes tests in web browser
  34. 34. Unit Testing Setup • For empty projects: • Add dependencies in package.json • Create karma.conf file • Configure testing • Implements tests • For existing projects: • Open project properties and configure
  35. 35. Unit Testing Setup
  36. 36. AWS Lambda Testing
  37. 37. What is AWS Lambda? • Function as a Service (Faas) from AWS • Stateless function that executes in the cloud • Executes in response to events (S3, DynamoDB, API Gateway, etc) • Can be implemented using • JavaScript (Node.js), Java, Python C# • Billed on executions: • First million executions are free • $0.20 per each million afterwards
  38. 38. Example Lambda Function exports.handler = function(event,context) { context.succeed('Hello ' + event.firstName + ' ' + event.lastName + ' you are at JavaOne 2017!'); }; { "firstName": "Ryan", "lastName": "Cuprak” } Handler Function
  39. 39. SAM – AWS Lambda Testing https://github.com/awslabs/aws-sam-local
  40. 40. AWS Lambda & NetBeans • NetBeans can test AWS Lambda locally • Prerequisites: • Install Docker • Install SAM Local - npm install -g aws-sam-local • Steps: 1. Create a Node.js project in NetBeans 2. Add aws-sdk to project via npm 3. Implement function 4. Add yaml configuration file 5. Add scripts entry to launch SAM
  41. 41. AWS Lambda & NetBeans Debugging steps: 1. Start SAM in debug mode 2. Trigger event for invocation 3. Attach debugger
