# queryParam

Constructs one named query-parameter AST node.

## Signatures

```ts
export declare const queryParam: (name: string, value: PathAst) => PathAst.QueryParam;
```

## Why

Literal and decoded query policies share the same value AST representation.

## Ownership and lifetime

`queryParam` returns a fresh plain AST node immediately and retains any supplied child nodes or arrays by reference; it acquires no external resource.
