Developer Experience: How happy are your engineers?

Developer Experience: How happy are your engineers?

With the complex tooling in the JavaScript ecosystem, different frameworks, CSS styles, different paradigms in architecture, mono repo, dependency management etc., every decision adds bits and pieces to your developer experience. When you have many engineers working together on a product or app, your engineers’ happiness is key to success. With the proper tooling, faster pipelines and a local environment, they can perform well and deliver fast!

This talk focuses on how to improve your developer experience and keep your team happy. It focuses on the complexity of front-end development tools, the ecosystem, and the culture you build and run it. I’ll discuss

- The setting up the build systems, decision on which choice can be right for you
- How different approaches can add/remove complexity to your work, e.g. decision on a mono repo, micro-frontends
- Testing tools, pipeline runs, code analysis
- From starting a fresh project to transforming it into a complex one, in each step, integrate how the developer experience can suffer from it and what are the options to prevent it.
