Function defineConfigSection

defineConfigSection<T>(definition: ConfigSection<T>): ConfigSection<T>
Declares a typed section over flat configuration keys.

Every entry in keys is read as prefix + key; the schema receives those values under their prefix-stripped names. For example, prefix: 'DATABASE_' and keys: ['URL'] read DATABASE_URL and pass { URL } to the schema. The returned declaration is an immutable snapshot, so later mutations to the caller-owned definition cannot change a cached section.
Type Parameters
- T
  The validated output produced by schema
Parameters
- definition: ConfigSection<T>
  The flat-key prefix, declared keys, and schema
Returns ConfigSection<T>
A reusable section definition for ConfigPluginOptions.sections
Example
```
const database = defineConfigSection({
  prefix: 'DATABASE_',
  keys: ['URL'],
  schema: { parse: (input) => input },
});
```
