conference faq what is the purpose of mastering javascript patterns mastering javascript patterns helps developers write code more clearly and efficiently improve code architecture catch up with team members and potentially become a consultant or mentor with better skills and deeper understanding of software principles what is a factory pattern in javascript the factory pattern is about defining a method for creating objects in a superclass but allowing subclasses to alter the type of objects that will be created it helps in creating a function that produces additional objects while maintaining specific principles what is a singleton pattern in javascript the singleton pattern ensures that a class has only one instance and provides a global point of access to it this pattern is useful for scenarios requiring a single shared resource or centralized management such as logging utilities or database connections what is an observer pattern in javascript the observer pattern involves a subject or publisher that maintains a list of its dependents observers or subscribers and notifies them of any state changes this pattern is useful for implementing distributed event handling systems such as in user interface frameworks why should i learn javascript patterns learning javascript patterns sets a normal developer apart from a skilled developer it improves coding principles and problem solving abilities helps make better decisions about code architecture and design and leads to fewer bugs greater job satisfaction and less stress about production issues can you give examples of javascript patterns used in popular frameworks yes examples include the factory pattern in next js for creating dictionary services the adapter pattern in next js server features the decorator pattern in node js for handling data events and the mvc pattern in angular for structuring applications what is a decorator pattern in javascript the decorator pattern allows you to wrap an existing object or function with new behavior without altering its structure it s like adding a layer of wrapping paper around a gift enhancing or modifying its functionality dynamically what is an adapter pattern in javascript the adapter pattern acts as a bridge between two incompatible interfaces allowing them to work together it converts the interface of a class into another interface that a client expects facilitating compatibility between different systems or components what is a composite pattern in javascript the composite pattern lets you build a tree structure of objects where individual objects and groups of objects composite objects are treated the same way it s useful for hierarchical data structures like organizational hierarchies or file systems what are some main categories of javascript patterns the main categories of javascript patterns include object creational patterns structural patterns behavioral patterns and architectural patterns best practices javascript patterns

performance debugging masterclass react summit 2023 170 min react performance debugging masterclass top content featured workshop ivan akulov ivan s first attempts at performance debugging were chaotic he would see a slow interaction try a random optimization see that it didn t help and keep trying other optimizations until he found the right one or gave up back then ivan didn t know how to use performance devtools well he would do a recording in chrome devtools or react profiler poke around it try clicking random things and then close it in frustration a few minutes later now ivan knows exactly where and what to look for and in this workshop ivan will teach you that too here s how this is going to work we ll take a slow app debug it using tools like chrome devtools react profiler and why did you render pinpoint the bottleneck and then repeat several times more we won t talk about the solutions in 90 of the cases it s just the ol regular usememo or memo but we ll talk about everything that comes before and learn how to analyze any react performance problem step by step note this workshop is best suited for engineers who are already familiar with how usememo and memo work but want to get better at using the performance tools around react also we ll be covering interaction performance not load speed so you won t hear a word about lighthouse react performance best practices advanced debug react debugger react performance react profiler react hooks tips only the pros know react summit remote edition 2021 177 min react hooks tips only the pros know top content featured workshop maurice de beijer the addition of the hooks api to react was quite a major change before hooks most components had to be class based now with hooks these are often much simpler functional components hooks can be really simple to use almost deceptively simple because there are still plenty of ways you can mess up with hooks and it often turns out there are many ways where you can improve your components a better understanding of how each react hook can be used you will learn all about the pros and cons of the various hooks you will learn when to use usestate versus usereducer we will look at using usecontext efficiently you will see when to use uselayouteffect and when useeffect is better react best practices react hooks deep dive react 18 hooks react profiler react typescript and tdd react advanced 2021 174 min react typescript and tdd top content featured workshop paul everitt reactjs is wildly popular and thus wildly supported typescript is increasingly popular and thus increasingly supported the two together not as much given that they both change quickly it s hard to find accurate learning materials react typescript with jetbrains ides that three part combination is the topic of this series we ll show a little about a lot meaning the key steps to getting productive in the ide for react projects using typescript along the way we ll show test driven development and emphasize tips and tricks in the ide react best practices typescript devtools web development test driven development react designing effective tests with react testing library react summit 2023 151 min designing effective tests with react testing library top content featured workshop josh justice react testing library is a great framework for react component tests because there are a lot of questions it answers for you so you don t need to worry about those questions but that doesn t mean testing is easy there are still a lot of questions you have to figure out for yourself how many component tests should you write vs end to end tests or lower level unit tests how can you test a certain line of code that is tricky to test and what in the world are you supposed to do about that persistent act warning in this three hour workshop we ll introduce react testing library along with a mental model for how to think about designing your component tests this mental model will help you see how to test each bit of logic whether or not to mock dependencies and will help improve the design of your components you ll walk away with the tools techniques and principles you need to implement low cost high value component tests table of contents the different kinds of react application tests and where component tests fit in a mental model for thinking about the inputs and outputs of the components you test options for selecting dom elements to verify and interact with them the value of mocks and why they shouldn t be avoided the challenges with asynchrony in rtl tests and how to handle them prerequisites familiarity with building applications with react basic experience writing automated tests with jest or another unit testing framework you do not need any experience with react testing library machine setup node lts yarn react testing best practices deep dive react testing react testing library test driven development react react patterns made simple

a library might seem easy at first glance but how do you choose the right library how do you upgrade an existing one and how do you wade through the documentation to find what you want in this workshop we ll discuss all these finer points while going through a general example of building a code editor using codemirror in react all while sharing some of the nuances our team learned about using this library and some problems we encountered javascript build tools check out more articles and videos we constantly think of articles and videos that might spark git people interest skill us

this talk discusses the usage of microfrontends in remix and introduces the tiny frontend library kazoo a used car buying platform follows a domain driven design approach and encountered issues with granular slicing tiny frontend aims to solve the slicing problem and promotes type safety and compatibility of shared dependencies the speaker demonstrates how tiny frontend works with server side rendering and how remix can consume and update components without redeploying the app the talk also explores the usage of micro frontends and the future support for webpack module federation in remix

epicreact dev testingjavascript com kent c dodds discusses the concept of problem elimination rather than just problem solving he introduces the idea of a problem tree and the importance of avoiding creating solutions prematurely kent uses examples like tesla s electric engine and remix framework to illustrate the benefits of problem elimination he emphasizes the value of trade offs and taking the easier path as well as the need to constantly re evaluate and change approaches to eliminate problems remix best practices web development using useeffect effectively react advanced 2022 30 min

conditions and cleanup and optimizing performance it also discusses the correct use of useeffect in react 18 the distinction between activity effects and action effects and the potential misuse of useeffect the talk highlights the benefits of using usequery or swr for data fetching the problems with using useeffect for initializing global singletons and the use of state machines for handling effects the speaker also recommends exploring the beta react docs and using tools like the stately ai editor for visualizing state machines react best practices state management react hook missing
