See the developer documentation.

We highly recommend using an IDE for development. The backend codebase adheres to SOLID principles, utilizes interfaces, static typing and generics. We recommend to start learning EspoCRM from the Dependency Injection article in the documentation.

Metadata plays an integral role in the EspoCRM application. All possible parameters are described with a JSON Schema, meaning you will have autocompletion in the IDE. You can also find the full metadata reference in the documentation.

The frontend is an SPA built on a custom framework. It utilizes nested views and service DI, with the core partially written in TypeScript. Developers primarily work with existing form and field view implementations.
