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.

This workshop has been presented at Node Congress 2021, check out the latest edition of this JavaScript Conference.

FAQ

Fastify is a web framework designed for building fast web applications with minimal overhead compared to NodeCore. It is extensible, supports hooks, plugins, decorators, and is schema-based, providing a great developer experience especially in production environments.

The source code for the Fastify workshop is publicly available on GitHub at the repository 'github.com/NearForm/the-fastify-workshop'.

Fastify's core features include high performance (fast execution and handling of requests with minimal overhead), extensibility through hooks, plugins, and decorators, built-in schema-based handling, and default logging capabilities.

Yes, Fastify provides good support for TypeScript, enhancing the developer experience by ensuring type safety and facilitating tooling and integrations.

Yes, Fastify is suitable for production applications. It was designed with performance and scalability in mind, making it capable of handling real-world production workloads effectively.

Fastify has built-in logging through the Pino logger. Pino is highly performant and allows for customized logging strategies, making it suitable for both development and production environments.

Fastify uses a schema-based approach to validate and serialize input and output. It typically uses JSON Schema for validation, which helps in defining the structure of the data and ensuring that the data adheres to specified formats.

To start the Fastify workshop, you need to have Node.js installed, specifically a Long Term Support (LTS) version such as Node 14. This setup ensures compatibility and stability with the Fastify framework.

Building WebApps That Light Up the Internet with QwikCity

Miško Hevery

Building instant-on web applications at scale have been elusive. Real-world sites need tracking, analytics, and complex user interfaces and interactions. We always start with the best intentions but end up with a less-than-ideal site.
QwikCity is a new meta-framework that allows you to build large-scale applications with constant startup-up performance. We will look at how to build a QwikCity application and what makes it unique. The workshop will show you how to set up a QwikCitp project. How routing works with layout. The demo application will fetch data and present it to the user in an editable form. And finally, how one can use authentication. All of the basic parts for any large-scale applications.
Along the way, we will also look at what makes Qwik unique, and how resumability enables constant startup performance no matter the application complexity.

The modern web would be different without rich client-side applications supported by powerful frameworks: React, Angular, Vue, Lit, and many others. These frameworks rely on client-side JavaScript, which is their core. However, there are other approaches to rendering. One of them (quite old, by the way) is server-side rendering entirely without JavaScript. Let's find out if this is a good idea and how Remix can help us with it?
Prerequisites- Good understanding of JavaScript or TypeScript- It would help to have experience with React, Redux, Node.js and writing FrontEnd and BackEnd applications- Preinstall Node.js, npm- We prefer to use VSCode, but also cloud IDEs such as codesandbox (other IDEs are also ok)

Have you ever struggled with designing and structuring your Node.js applications? Building applications that are well organised, testable and extendable is not always easy. It can often turn out to be a lot more complicated than you expect it to be. In this live event Matteo will show you how he builds Node.js applications from scratch. You’ll learn how he approaches application design, and the philosophies that he applies to create modular, maintainable and effective applications.

Platformatic allows you to rapidly develop GraphQL and REST APIs with minimal effort. The best part is that it also allows you to unleash the full potential of Node.js and Fastify whenever you need to. You can fully customise a Platformatic application by writing your own additional features and plugins. In the workshop, we’ll cover both our Open Source modules and our Cloud offering:- Platformatic OSS (open-source software) — Tools and libraries for rapidly building robust applications with Node.js (https://oss.platformatic.dev/).- Platformatic Cloud (currently in beta) — Our hosting platform that includes features such as preview apps, built-in metrics and integration with your Git flow (https://platformatic.dev/).
In this workshop you'll learn how to develop APIs with Fastify and deploy them to the Platformatic Cloud.

Deno 1.9 introduced a new web server API that takes advantage of Hyper, a fast and correct HTTP implementation for Rust. Using this API instead of the std/http implementation increases performance and provides support for HTTP2. In this workshop, learn how to create a web server utilizing Hyper under the hood and boost the performance for your web apps.

Passwordless authentication may seem complex, but it is simple to add it to any app using the right tool.
We will enhance a full-stack JS application (Node.JS backend + React frontend) to authenticate users with OAuth (social login) and One Time Passwords (email), including:- User authentication - Managing user interactions, returning session / refresh JWTs- Session management and validation - Storing the session for subsequent client requests, validating / refreshing sessions
At the end of the workshop, we will also touch on another approach to code authentication using frontend Descope Flows (drag-and-drop workflows), while keeping only session validation in the backend. With this, we will also show how easy it is to enable biometrics and other passwordless authentication methods.
Table of contents- A quick intro to core authentication concepts- Coding- Why passwordless matters
Prerequisites- IDE for your choice- Node 18 or higher

Suspense is a mechanism for orchestrating asynchronous state changes in JavaScript frameworks. It ensures async consistency in UIs and helps avoid trust erosion and inconsistencies. Suspense boundaries are used to hoist data fetching and create consistency zones based on the user interface. They can handle loading states of multiple resources and control state loading in applications. Suspense can be used for transitions, providing a smoother user experience and allowing prioritization of important content.
