Starting with a detailed overview of Redux, we will follow the test-driven development (TDD) approach to develop single-page applications. We will set up JEST for testing and use JEST to test React, Redux, Redux-Sage, Reducers, and other components. We will then add important middleware and set up immutableJS in our application. We will use common data structures such as Map, List, Set, and OrderedList from the immutableJS framework. We will then add user interfaces using ReactJS, Redux-Form, and Ant Design.We will explore the use of react-router-dom and its functions. We will create a list of routes that we will need in order to create our application, and explore routing on the server site and create the required routes for our application. We will then debug our application and integrate Redux Dev tools.We will then set up our API server and create the API required for our application. We will dive into a modern approach to structuring our server site components in terms of Model, Controller, Helper functions, and utilities functions. We will explore the use of NodeJS with Express to build the REST API components.

Refaktoryzacja. Ulepszanie struktury istniejącego kodu. Wydanie II
Martin Fowler
Refaktoryzacja ma na celu ulepszanie istniejącego kodu. Poprawia jego strukturę, czytelność i wydajność. Prowadzona poprawnie, cechuje się zdyscyplinowaniem metody, systematycznością i konsekwencją w działaniu, a także ciągłym minimalizowaniem ryzyka wprowadzenia błędów. Niemniej refaktoryzacja jest ryzykowna. Polega na wprowadzaniu zmian do działającego kodu, co może doprowadzić do powstania trudno wykrywalnych błędów. Ryzyko wzrasta, jeśli refaktoryzacja jest przeprowadzana w sposób nieprzemyślany. Okazuje się, że transformacja kodu, która ma doprowadzić do jego ulepszenia, to spore wyzwanie. Ta książka jest zaktualizowanym wydaniem praktycznego przewodnika po refaktoryzacji. Choć jest przeznaczona dla profesjonalnego programisty, znalazło się tu zrozumiałe wprowadzenie do tego zagadnienia z opisem celów, technik i możliwości refaktoryzacji. Wspomniano także o problemach związanych z refaktoryzacją. Natomiast zasadniczą część książki stanowi znakomicie uzupełniony i wzbogacony katalog przekształceń refaktoryzacyjnych. Do zilustrowania poszczególnych technik refaktoryzacji autorzy wybrali język JavaScript, jednak kod został przedstawiony w taki sposób, aby prezentowane koncepcje bez trudu zrozumiał każdy programista. W tej książce między innymi: solidne wprowadzenie do refaktoryzacji przekształcenia refaktoryzacyjne: zasady, sposoby, testy enkapsulacja w refaktoryzacji upraszczanie wyrażeń oraz porządkowanie danych, zmiennych i pól refaktoryzacja klas i API Refaktoryzacja: czytelny kod, wydajne działanie i brak błędów! »» Spis wszystkich odwołań do stron w książce

Remote Usability Testing. Actionable insights in user behavior across geographies and time zones
Inge De Bleecker, Rebecca Okoroji
Usability testing is a subdiscipline of User Experience. Its goal is to ensure that a given product is easy to use and the user's experience with the product is intuitive and satisfying. Usability studies are conducted with study participants who are representative of the target users to gather feedback on a user interface. The feedback is then used to refine and improve the user interface.Remote studies involve fewer logistics, allow participation regardless of location and are quicker and cheaper to execute compared to in person studies, while delivering valuable insights. The users are not inhibited by being in a new environment under observation; they can act naturally in their familiar environment. Remote unmoderated studies additionally have the advantage of being independent of time zones.This book will teach you how to conduct qualitative remote usability studies, in particular remote moderated and unmoderated studies. Each chapter provides actionable tips on how to use each methodology and how to compensate for the specific nature of each methodology. The book also provides material to help with planning and executing each study type.
