#api development

API stands for Application Programming Interface. It is a set of functions and procedures that allow two or more applications to communicate with each other. In the context of JavaScript, an API is a set of commands, functions, protocols, and objects that can be used to create interactive web-based applications. APIs help developers access data from external sources and integrate it into their own web applications, making them more dynamic and user friendly.

Best Practices and Patterns for Managing API Requests and States
With the rise of frameworks, such as React, Vue or Angular, the way websites are built changed over the years. Modern applications can be very dynamic and perform multiple API requests to populate a website with fresh content or submit new data to a server. However, this paradigm shift introduced new problems developers need to deal with. When an API request is pending, succeeds, or fails, a user should be presented with meaningful feedback. Other problems can comprise API data caching or syncing the client state with the server. All of these problems require solutions that need to be coded, but these can quickly get out of hand and result in a codebase that is hard to extend and maintain. In this workshop, we will cover how to handle API requests, API states and request cancellation by implementing an API Layer and combining it with React-Query.
To make the most out of this workshop, you should be familiar with React and Hooks, such as useState, useEffect, etc. If you would like to code along, make sure you have Git, a code editor, Node, and npm installed on your machine.

Building GraphQL APIs on top of Ethereum with The Graph
Workshop Free
The Graph is an indexing protocol for querying networks like Ethereum, IPFS, and other blockchains. Anyone can build and publish open APIs, called subgraphs, making data easily accessible.
In this workshop you’ll learn how to build a subgraph that indexes NFT blockchain data from the Foundation smart contract. We’ll deploy the API, and learn how to perform queries to retrieve data using various types of data access patterns, implementing filters and sorting.
By the end of the workshop, you should understand how to build and deploy performant APIs to The Graph to index data from any smart contract deployed to Ethereum.

Building GraphQL APIs With The Neo4j GraphQL Library
Workshop Free
This workshop will explore how to build GraphQL APIs backed Neo4j, a native graph database. The Neo4j GraphQL Library allows developers to quickly design and implement fully functional GraphQL APIs without writing any resolvers. This workshop will show how to use the Neo4j GraphQL Library to build a Node.js GraphQL API, including adding custom logic and authorization rules.
Table of contents:
- Overview of GraphQL and building GraphQL APIs
- Building Node.js GraphQL APIs backed a native graph database using the Neo4j GraphQL Library
- Adding custom logic to our GraphQL API using the @cypher schema directive and custom resolvers
- Adding authentication and authorization rules to our GraphQL API

How to Troubleshoot API Errors and Reduce MTTD/R
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.
We prefer to use VSCode for a better experience (other IDEs are fine)
Preinstall npm and node
