Node Congress 2021

The benefits of Node.js to develop real-time applications at scale are very well known. As Node.js architectures get more and more complex, visualization of your microservices-based architecture is crucial. However, the visualization of microservices is incredibly complex given the scale and the transactions across them. In this workshop, you will learn how to leverage service maps to instantly understand your architecture and troubleshoot any API error.

We will write a simple Express application and explore best practices when using Express. Then, we’ll deploy the application on AWS, integrate the environment with Epsagon, and deep-dive into various features of the platform to enable immediate detection and fast troubleshooting of application errors. Goals: Visualizing your architecture, monitoring your applications, reducing your mean time to detection and recovery (MTTD and MTTR).
Who should attend?
DevOps, Engineers, Cloud Architects, IT, Software Developers, Solution Architects and Engineers, SREs, and anyone who is running microservice-based applications (Kubernetes, containers, serverless functions, and more) in the cloud.

PrerequisitesWe prefer to use VSCode for a better experience (other IDEs are fine)Preinstall npm and node        Pre-existing AWS Account - You can create a free tier here        Attendees are free to create an Epsagon account in advance here, not mandatory

InfluxDB is an open source time series database that empowers developers to build IoT, analytics and monitoring software. It is purpose-built to handle the massive volumes and countless sources of time-stamped data produced sensors, applications and infrastructure. This workshop showcases a fully functional sample application called IoT Center that is built on InfluxDB. This application demonstrates the capabilities of the InfluxDB platform to develop a JavaScript-enabled time-series-based application. It collects, stores and displays a set of values that include temperature, humidity, pressure, CO2 concentration, air quality, as well as provide GPS coordinates from a set of IoT devices. With this data stored in InfluxDB, the application can query this data for display as well as write data back into the database.
This hands-on workshop will show students how to install this open source code to learn how to query and write to InfluxDB using the InfluxDB JavaScript client, and gain familiarity with the Flux lang query language which is designed for querying, analyzing, and acting on time series data. And finally, collect and visualize performance data of the Node JS application.

We’ve all heard the buzz around pushing application security into the hands of developers, but if you’re like most companies, it has been hard to actually make this a reality. You aren’t alone - putting the culture, processes, and tooling in place to make this happen is tough - especially for sophisticated applications. Join Scott Gerlach (CSO, StackHawk) and Liran Tal (Developer Advocate, Snyk) as they dive into how you can add AppSec testing to your CI/CD pipeline to ship secure code faster.
Prerequisites:Docker is a nice to have

The "Web APIs with Sails" workshop focuses on creating Node.js web APIs with the Sails framework.The workshop begins with a beginner's introduction to the Sails framework, we touch on getting started with Sails, installing Sails in your machine, then touch on Sails framework philosophy, concepts, and features.We continue with the hands-on building of a Web API in Sails from Scratch and test the endpoints with Postman. We round up writing tests for the endpoints, setting up a GitHub action to run our tests when we push to GitHub then deploy our Web API to Heroku cloud.
Prerequisites:A good understanding of JavaScript and Node.js fundamentals. I prefer to use VS Code for code editing but you can use and editor you want. I expect a preinstall of Node.js and NPM

This workshop teaches you the basics of serverless application development with TypeScript. We'll start with a simple Lambda function, set up the project and the infrastructure-as-a-code (AWS CDK), and learn how to organize, test, and debug a more complex serverless application.
Table of contents:        - How to set up a serverless project with TypeScript and CDK        - How to write a testable Lambda function with hexagonal architecture        - How to connect a function to a DynamoDB table        - How to create a serverless API        - How to debug and test a serverless function        - How to organize and grow a serverless application

Fastify is an HTTP framework for Node.js that focuses on providing a good developer experience without compromising on performance metrics. What makes Fastify special are not its technical details, but its community which is wide open for contributions of any kind. Part of the secret sauce is Fastify plugin architecture that enabled developers to write more than a hundred plugins.This hands-on workshop is structured around a series of exercises that covers from basics "hello world", to how to structure a project, perform database access and authentication.
