• 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

Setup
NetBeans Setup
1. Install Node.js
2. Download Sources
3. Setup npm/express
Install Chrome Plugin

Configure Runtime Environment
Select Browser to use for testing – project specific.
Note testing on connected
devices.

Angular / TypeScript Support
Install via Plugin Manager
Deep Dive
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.
Demos• Simple Node.js application & debugging
• Node.js + Express
• Gulp Demo
• Angular 4 Demo with TypeScript & Webpack
• https://github.com/angular/angular2-seed
Unit Testing
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
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
Unit Testing Setup
AWS Lambda Testing
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
Example Lambda Functionexports.handler = function(event,context) {
context.succeed('Hello ' + event.firstName + ' ' +
event.lastName + ' you are at JavaOne 2017!');
};
{
"firstName": "Ryan",
"lastName": "Cuprak”
}

SAM – AWS Lambda Testing
https://github.com/awslabs/aws-sam-local
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
AWS Lambda & NetBeansDebugging steps:
1. Start SAM in debug mode
2. Trigger event for invocation
3. Attach debugger
