Learn more about how to leverage the default features of npm workspaces to help you manage your monorepo project while also checking out some of the new npm cli features.

Demand for DevOps has increased in recent years as more organizations adopt cloud native technologies. Complexity has also increased and a "zero to hero" mentality leaves many people chasing perfection and FOMO. This session focusses instead on why maybe we shouldn't adopt a technology practice and how sometimes teams can achieve the same results prioritizing people over ops automation
&
controls. Let's look at amounts of and fine-tuning everything as code, pull requests, DevSecOps, Monitoring and more to prioritize developer well-being over optimization perfection. It can be a valid decision to deploy less and sleep better. And finally we'll examine how manual practice and discipline can be the key to superb products and experiences.

We've all asked ourselves this while waiting an eternity for our CI job to finish. Slow CI not only wrecks developer productivity breaking our focus, it costs money in cloud computing fees, and wastes enormous amounts of electricity. Let’s take a dive into why this is the case and how we can solve it with better, faster tools.

Code tasks like linting and testing are critical pieces of a developer’s workflow that help keep us sane like preventing syntax or style issues and hardening our core business logic. We’ll talk about how we can use GitHub Actions to automate these tasks and help keep our projects running smoothly.

* intro to DB application architecture (gateway + backend, multi-module react app + component library, etc)
* Deep dive into CI/CD pipeline to do component library build + publish, app deploys pre canary (branch, dev, staging, prod), Lambda@Edge role
* Side  note - multi module applications, enabling the right level of modularity, and B2B SaaS vs B2C
* First canary problem - run full FE regression against stable (release candidate) backend early and often - before FE release candidates are cut
* Second canary problem - run pointed FE regression even earlier - before MRs are even merged
* Third canary question - what does this look like in production? Once again, B2B SaaS vs B2C
* End result - Canaries in the CloudFront! 

Monorepos is a hot topic in the TypeScript/JavaScript community these days, but getting a high performing monorepo setup from the ground up can be challenging. In this talk, we will see how Turborepo can help you to move your monorepo tasks at light speed.

In a nutshell, mobile DevOps best practises for React Native apps, from code to release.

Creating and deploying new software is risky. We've all seen how easily bugs arise, causing software to be poorly delivered or to the wrong people. What's more, depending on how tightly we couple our systems and services, they can interact unexpectedly and unfortunately with existing software or hardware. Beyond unintended consequences, we can also find that people can use our services for nefarious purposes. It's essential to have safety nets in place when things don't go as planned or people attempt to break the rules. In this session, we'll discuss how feature flags can work in both temporary and permanent scenarios to enable you to break the quality triangle and deliver quality promptly.

Learn how to instrument Node and client applications using OpenTelemetry and popular open-source observability tools like Prometheus and Grafana.

Docker Extensions are a way to power up your development experience by adding in tools to help with debugging, testing, networking, security, and more. Developers can get started in Docker Desktop with partner-built extensions or use their creativity with the Docker Extensions SDK. This session will cover Docker Extensions and the Docker Extensions SDK — including a demonstration of Docker Extensions within Docker Desktop. You’ll also learn how to get started and what’s next for extensions.

As your team grows and becomes multiple teams, the size of your codebase follows. You get to 100k lines of code and your build time dangerously approaches the 10min mark 😱 But that’s not all, your static CI checks (linting, type coverage, dead code) and tests are also taking longer and longer...
How do you keep your teams moving fast and shipping features to users regularly if your PRs take forever to be tested and deployed?
After exploring a few options we decided to go down the Nx route. Let’s look at how to migrate a large codebase to Nx and take advantage of its incremental builds!

At AG Grid, we maintain thousands of code demos, with the same demo in Angular, React, Vue, and Vanilla JS. Additionally, each framework has different variations covering JavaScript, TypeScript, Modules, Packages, Hooks, Classes, Vue 2, and Vue 3. How do we do it? We automate. This session will explain how we start with a single TypeScript version and automatically convert it to every combination we need and finally use Cypress to test the converted example.

How to update hundreds of projects all at once? With organizations rapidly growing, demand for the scalability of the teams grows which directly impacts projects structure and ownership. The usual dilemma is mono- vs. multi-repos, but ... What if I tell you that it does not matter much? Both approaches can punch you in the face at some point, so perhaps it is better to think bottom-up.
Today I will walk you through some of the biggest challenges that exist in both approaches and those are managing dependencies across a few hundred projects, global code updates and many other things. I will also show you examples of how we solved this inside Infobip through building our own internal libraries.

Teams are getting bigger and bigger following the micro-frontends architecture. Observability for teams on a scale becomes even more important in order not only to be able to identify potential issues in the runtime, but also separating the responsibilities. In this presentation we’ll learn how this can achieved.

As we all know, dealing with Kubernetes YAML is not very intuitive (especially for those just getting starting) and the more resources and dependencies are added the messier and more complex the process becomes. In this talk, we'll explore how we can use Typescript and Deno to bring typing, composition, code-reuse, and testing as an alternative to YAML - that doesn't include these capabilities, all while still remaining declarative and easy to use.

In this talk micro frontend expert Florian Rappl will introduce the pattern of creating a Siteless UI. This is a frontend composed of different pieces that can be developed independently and are deployed without having or managing any server. Florian will show you how to get started in that space, what decisions to take, and what pitfalls you should avoid.

What does Conway's Law have in common with the video game League of Legends? They can both teach us about how to organise development teams that achieve collective intelligence. When it comes to the art of software development, it's never a game of chance

In this talk, you will learn how to optimise your Node.js development and release workflow to Kubernetes with Skaffold and Rancher Desktop. Using these tools together helps enhance the local K8s development experience mirroring a real cluster experience, as well as the release workflow you would have for your remote cluster. We will cover the challenges of local Kubernetes development, how Skaffold and Rancher Desktop help, demonstrations of local releases to a cluster and how to use the same configuration for remote cluster releases.

Do you want to release your applications more rapidly with lower risk? Feature flags make this possible. This talk will concretely demonstrate that this is possible and easily within your reach.

When working with a monorepo, there are multiple Challenges: packages installation, packages linking, development processes (build, lint, testing) and deployment processes. Those challenges vary the type of artifacts in our monorepo (micro services, FE App, packages etc.). We will explore different approaches and tools for monorepos and their pro and cons.

Do you know what’s really going on in your node_modules folder? Software supply chain attacks have exploded over the past 12 months and they’re only accelerating in 2022 and beyond. We’ll dive into examples of recent supply chain attacks and what concrete steps you can take to protect your team from this emerging threat.

CDK is growing in popularity in the AWS ecosystem, and is set to be the successor of CloudFormation, being built natively for the configuration of AWS resources. Learn how this is a game changer for NodeJS programmers
&
stacks.

Learn about tools to trace frontend to backend data and increase visibility on errors and performance. We'll go through how to know which teams are responsible for which error, what the impact is, and all the context needed to solve it.

The benefit of software dependencies is that they allow developers to deliver software faster building on previous code. Dependencies are integral part of the software development cycle and they will be used at different stages i.e. development, execution or testing. Yet dependencies not only may introduce risks that are often overlooked, but their fast resolution and compliance with license types must be taken into consideration. In this extremely fast session we will see some of the advantages of using a mature, robust artifact manager for npm, bower and other package managers.

Vultr's Walt Ribeiro takes users through steps to easily produce websites with Vultr using their One-Click Marketplace and Object Storage. In this talk, Walt will demonstrate how to configure your account, how to browse and deploy from Vultr Marketplace, and how to stand up a basic website using a simple web or mobile-based UI. Other flagship products and tools developers love will be highlighted along the way!

Traditional security testing for JS apps has focused on the front-end, but actual security issues most often lie in the backing REST API. Join StackHawk co-founder Scott Gerlach for a quick overview of why you need to rethink how you test your JS apps and how StackHawk can help you find and fix security bugs fast.

In this session, I'll use a demo to demonstrate how you can easily take ownership of your Code Quality with SonarCloud. You'll see how a simple, automated methodology ensures you and your Team to only commit Clean Code.

In this short lightning talk I’ll register a domain and demonstrate how to use the DNSimple NodeJS API client to register a domain name and set up the DNS needed to make it point to a web service in just a few minutes.

NodeJS is a server-side representation of Javascript that can work well as an application's backend and can be run on various servers and infrastructures. In this talk, we'll be going through the journey of how Nodejs has been deployed over the years via various infrastructures from PaaS to Containers.

As an industry, we understand that effective test automation is a key enabler - or inhibitor to - realizing the potential of DevOps. While automation is critical to innovating with speed and quality, very few of us are happy with the results. This talk will cover how low-code test automation solutions - like mabl - enable teams to embed automated tests directly into the development pipeline, strategies to overcome traditional challenges with test automation, and how to build a foundation for an efficient and effective test strategy.

In this lightning talk, you will see:
The lack of visibility on React applications
How to install the Sentry React SDK
How Sentry can help you identify errors and slowdowns within your React App so you can see faster, solve quicker and continuously learn from your applications

For years, not being able to cache GraphQL was considered one of its main downsides compared to RESTful APIs. Not anymore. GraphCDN makes it possible to cache almost any GraphQL API at the edge, and not only that but our cache is even smarter than any RESTful cache could ever be. Let's dive deep into the inner workings of GraphCDN to figure out how exactly we make this happen.

We consider what IaC (Infrastructure as Code) is and why we should invest our time/money into it. It’s going to be a workshop-style talk and as the result, the end of it you will have complete infrastructure as code for React application on AWS written in TypeScript

This talk will cover best practices for performance, stability, security, and maintainability of CI/CD pipelines, each supported with practical examples and counterexamples and tailored towards Vue.js developers.

The npm CLI has been,
&
continues to be, a core developer tool of the Node.js/JavaScript ecosystem. This past year npm@7 became Generally Availble, introducing with it a wealth of changes
&
net-new capabilities including: lockfile upgrades, workspace support, installing peer dependencies default, npm diff, npm explain, npm exec, npm set-script
&
much, much more. We'll dive into this work as well as share some exciting news about what to expect in the weeks
&
months to come.

For the past 10 years we diligently applied DevOps principles to our Backend services, but what about the Frontend? Can we transfer some of that knowledge between these very different, yet very similar, worlds? The answer is yes, and in this talk I'll show you how DevOps principles helped us at DAZN to build our web applications for Smart TV
&
Gaming Consoles.

Our web app is finally ready to go live but which deployment tool should we use? With the rise of JAMstack, we have a multitude of options from Vercel, Netlify, to Firebase. Certainly, performance is key for us so we want to know which one is the fastest. In this talk, we will do a real-world benchmark comparing the most known JAMstack deployment options and discuss pros and cons.

Fed up with merge conflicts and system failures after a big release? Feature flags can be your lifesaver!
We strive to get new features to the hands of our users as fast as we sustainably can. Some features can take longer to develop and touch other parts of the system. If not handled with care, these kinds of features can result in merge conflicts that keep developers up all night, not to mention the dreaded system failures following a big release. Equipped with feature flags, we can avoid this nightmare and continuously deploy code changes safely.
This talk consists of practical tips on how to use feature flags as release toggles.

Over the last few years, the JS web app community has seen a growing awareness and focus on performance
&
scalability. The days when prominent production sites serve entirely-blank pages waiting on monolithic bundles of megates of JavaScript are (mostly!) behind us.
A big part of that has been deeper integration with CDNs, after all, round-trip latency is one of the primary determiners of performance for a global audience. But frameworks, and the companies that support them, have different approaches to how they can be used, and the operational complexities their strategies introduce have real consequences.
But what if, instead of a dynamic origin sending instructions to a static CDN, you could run your application directly on the edge? As it turns out, that doesn't just improve performance, it also vastly simplifies our deployment and maintenance lives too.

Microservices present many advantages for running modern software, but they also bring new challenges for both Deployment and Operational tasks. This session will discuss advantages and challenges of microservices and review the best practices of developing a microservice-based architecture.
We will discuss how container orchestration using Kubernetes or Red Hat OpenShift can help us and bring it all together with an example of Continuous Integration and Continuous Delivery (CI/CD) pipelines on top of OpenShift.

Ever since JavaScript has become a language for writing applications, build tools and especially bundlers have been around. They solve the discrepancy between writing code that is easy to maintain and writing code that loads efficiently in a browser. But there are advantages to bundling JavaScript code that go well beyond the browser, from cloud functions to servers to command line tools.
RollupJS is special in that it was always designed from the ground up to be a general purpose bundler rather than a frontend specific tool. In this talk, we will have a look in what way other scenarios can profit from bundling. But more importantly, I will show you how RollupJS not only generates superior output in many situations, but how easy it is to tailor its output to custom requirements and non-standard scenarios. We will see how to patch up code, mock and replace dependencies, elegantly inject build information and control the chunk generation when code-splitting, all with a just few lines of code.

In this talk, I will demonstrate how to create a CI/CD pipeline for a React application in AWS. We'll pull the source code from GitHub and run tests against the application before deploying it to an S3 bucket for static site hosting. The site will then be distributed using CloudFront which will point to the S3 bucket. All of the infrastructure will be built using Terraform. In addition, I'll make use of Terragrunt to show how to create this setup for multiple environments.

Ever run code in CI/CD and builds pass only to fail during deployment? This presentation will discuss the advantages of Smoke Test patterns in CI/CD pipelines using Infrastructure as Code (IaC). Learn how teams can leverage automation to ensure apps are tested live in target environments which provide valuable insights pre-deployment. Angel will demonstrate how to leverage IaC to provision infrastructure, deploy apps, test then destroy all the resources created in a single CI/CD pipeline run.

In this session, I’ll surface relevant context regarding crashes and performance issues in my JS-web-app. I’ll cover how to investigate errors and pinpoint where slowness is introduced.

Software delivery is a top priority for organizations that own software, yet it remains one of the most challenging problems enterprises face today. Continuous integration (CI) and continuous delivery (CD) are software practices that allow organizations and teams to deliver code to customers quickly, safely, and repeatedly. Whether it's to improve development, operations, or security, CI/CD pipelines give engineers and teams more time to work on things that matter and less time struggling with the risk, standards, and velocity of deployments. Join this session to learn about the components of CI/CD and how to build and scale pipelines for the future.

There's a lot that goes into building a modern application: the frontend for users, data persistence, user authentication and authorization, business logic, cloud deployment, and much more. The AWS Amplify Admin UI allows users to create and deploy an offline-ready application backend in clicks and then extend it with code, lowering the complexity of fullstack development for frontend and mobile developers. We'll build a fullstack application backed multiple AWS services including Cognito, Appsync, and S3 in minutes.
