            ## Node Types


            ### 1. `function`

            **Definition**:  

            A **Hydra function node** used to provide a *subject* or perform a
            custom computation. It encapsulates reusable logic defined within
            the Hydra platform.


            ### 2. `flow`

            **Definition**:  

            A node that **invokes another flow**, either **synchronously** or
            **asynchronously**, enabling flow modularization and reuse.


            ### 3. `condition`

            **Definition**:  

            A **branching node** that evaluates a condition to determine the
            **flow of execution**, similar to `if`/`else` logic in programming.


            ### 4. `map`

            **Definition**:  

            A **data transformation node** used to **reshape or remap the
            payload**, allowing the flow to adapt the structure of data as it
            progresses.


            ### 5. `eval`

            **Definition**:  

            Executes **simple JavaScript code** to dynamically **evaluate
            expressions**, perform calculations, or manipulate data inline
            within the flow.


            ### 6. `integration`

            **Definition**:  

            Similar to a `function` node, but specifically tied to **predefined
            APIs**. It uses an HTTP-like interface and references **a known set
            of external services** managed by the platform.
