Developer Experience (DX) refers to how developers feel when using a tool, framework, API, library, or platform—essentially, it’s the user experience (UX) for developers. It measures how easy, efficient, and enjoyable it is for developers to get their work done.
Key aspects of DX:
- Ease of use – How simple is it to set up and start using?
- Documentation – Is it clear and helpful?
- Tooling – Are the tools reliable and developer-friendly?
- Error handling – Are error messages understandable?
- Support – Are there guides, examples, and community help?
