• 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

Download plugin: https://github.com/Everlaw/nbts/

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
