#case study

Come and learn how you can supercharge your modern and secure applications using GraphQL and Javascript. In this workshop we will build a GraphQL API and we will demonstrate the benefits of the query language for APIs and what use cases that are fit for it. Basic Javascript knowledge required.

The workshop overviews key architecture principles, design patterns, and technologies used to build microservices in the Node.js stack. It covers the theory of the GRPC framework and protocol buffers mechanism, as well as techniques and specifics of building isolated services using the monorepo approach with lerna and yarn workspaces, TypeScript. The workshop includes a live practical assignment to create a currency converter application that follows microservices paradigms. It fits the best developers who want to learn and practice GRPC microservices pattern with the Node.js platform.
Prerequistes:- Good understanding of JavaScript or TypeScript- Experience with Node.js and writing Backend applications- Preinstall Node.js, npm- Preinstall Protocol Buffer Compiler- We prefer to use VSCode for a better experience with JavaScript and TypeScript (other IDEs are also ok)

You have been tasked with creating a collaborative text editing feature within your company’s product. Something along the lines of Notion or Google Docs.
CK 5 is a feature-rich framework and ecosystem of ready-to-use features targeting a wide range of use cases. It offers a cloud infrastructure to support the real-time collaboration system needs. During this workshop, you will learn how to set up and integrate CK 5. We will go over the very basics of embedding the editor on a page, through configuration, to enabling real-time collaboration features. Key learnings: How to embed, set up, and configure CK 5 to best fit a document editing system supporting real-time collaboration.
Table of contents:- Introduction to the CK 5 ecosystem.- Introduction to a “Notion-like” project template.- Embedding CK 5 on a page.- Basic CK 5 configuration.- Tuning up CK 5 for a specific use case.- Enabling real-time editing features.

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 + Vanilla JS frontend) to authenticate users with One Time Passwords (email) and OAuth, including:
- User authentication – Managing user interactions, returning session / refresh JWTs- Session management and validation – Storing the session securely 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.

In this workshop, we will go over how to build a knowledge base using Gatsby, a static site generator Framework that uses React and graphQL, Contentful, a Headless CMS to drive the content and deploy it to AWS S3.

npm and security, how much do you know about your dependencies?Hack-along, live hacking of a vulnerable Node app https://github.com/snyk-labs/nodejs-goof, Vulnerabilities from both Open source and written code. Encouraged to download the application and hack along with us.Fixing the issues and an introduction to Snyk with a demo.Open questions.

API's/Backends are difficult and we need websockets. You will be using VS Code as your editor, Parcel.js, Chakra-ui, React, React Icons, and Appwrite. By the end of this workshop, you will have the knowledge to build a real-time app using Appwrite and zero API development. Follow along and you'll have an awesome chat app to show off!
