Function omitGroups

omitGroups<T extends ApiContract, K extends string | number | symbol>(
contract: T,
...groups: K[],
): Readonly<Omit<T, K>>
Returns a new contract with the specified groups removed.

The TypeScript return type is Omit<T, K> — the listed groups are absent at both runtime and compile time. Useful for stripping debug, internal, or admin groups before sharing a contract with less-privileged consumers.
Type Parameters
- T extends ApiContract
  The shape of the source contract.
- K extends string | number | symbol
  The union of group keys to remove.
Parameters
- contract: T
  The contract to omit from.
- ...groups: K[]
  The group keys to exclude.
Returns Readonly<Omit<T, K>>
A new frozen contract without the listed groups.
Example
```
const fullApi = defineApi({ todos: {...}, auth: {...}, admin: {...}, debug: {...} });

// Strip internal groups before exporting to clients
const publicApi = omitGroups(fullApi, 'admin', 'debug');
// TypeScript: { todos: ..., auth: ... }
```
