## Subsystems

Ordered by how much of the rest of the system depends on them, not by how much code they
contain. A small module many things import shapes this codebase more than a large one nothing
imports.

| Subsystem | Depended on by | Entities | Starts at |
|---|---|---|---|
| **Utils** | 6 | 148 | `Accept`, `parseAccept` |
| **Helper** | 5 | 109 | `Accept`, `acceptsConfig` |
| **Jsx** | 2 | 147 | `RenderToStringOptions`, `RenderToReadableStreamOptions` |
| **Middleware** | 1 | 110 | `handler`, `handler` |
| **Client** | 1 | 25 | `BuildSearchParamsFn`, `ClientRequestOptions` |
| **Docs** | 0 | 73 | `Contributor Covenant Code of Conduct`, `Contribution Guide` |
| **Adapter** | 0 | 71 | `getConnInfo`, `LambdaEvent` |
| **Router** | 0 | 21 | `LinearRouter`, `PatternRouter` |

`Client`, `Docs` depend on no other subsystem here — they are the leaves.
