À propos de Sylvain
Bonjour 🖖
Je m'appelle Sylvain, je suis développeur depuis près de 16 ans. Depuis huit ans, je me concentre sur TypeScript, un langage que j'adore et qui m'a permis d'écrire le livre "TypeScript - Notions fondamentales". Du côté de la communauté, je co-organise le meetup TypeScript de Paris avec quelques amis et je suis également Microsoft MVP dans la catégorie Developer Technologies !
Je suis passionné par le développement web depuis le début de ma carrière, et plus particulièrement côté backend. J'aime créer des services web en utilisant mes patterns préférés : CQRS et Event Sourcing. J'aime aussi la méthodologie Agile, l'approche eXtreme Programming et le Behavior Driven Development. En ce qui concerne le cloud, je suis un afficionado d'AWS, en particulier les services Serverless tels que Lambda, DynamoDB, Event Bridge, etc. Je suis également un grand fan de CloudFormation ! J'aime utiliser CDK pour mon Infra as Code et avec GitHub Actions, c'est ma combinaison préférée 😎.

- Editions ENIAuthorEDITION DE LOGICIELSnovembre 2019 - Aujourd'hui (6 ans et 7 mois)Nantes, FranceWriting of the book (french) "TypeScript Notions Fondamentales"Release date:- November 8, 2019 (version 1)- August 21, 2023 (version 2)Link: https://www.editions-eni.fr/livre/typescript-notions-fondamentales-2e-edition-9782409041266This book on the TypeScript language is intended for developers, who already have programming experience in other languages, who wish to optimize and secure the production of JavaScript code in a development project. If the basic knowledge of JavaScript is a plus for reading this book, it is not essential to understand the different concepts studied.In the first chapter, the authors first present the principles of language operation before setting up the development environment used for the examples, which is based on Visual Studio Code and Node.js. Then, in the following chapters, the reader discovers the different functionalities of the language (types, modules, decorators, genericity, asynchronism, advanced types...) as well as the possible programming paradigms (object-oriented programming and functional programming).Finally, the last chapter proposes an implementation of the different concepts studied through the step-by-step development of a Node.js application with the Fastify library. It also allows you to discover how to enrich the operation of a library by using the functionalities of TypeScript and several design templates (MVC, Repository, dependency injection).
