- name: 'set-cookie' | 'Set-Cookie'): string[];
Get all headers matching the name
Only supports
"Set-Cookie". All other headers are empty arrays.@param nameThe header name to get
@returnsAn array of header values
const headers = new Headers(); headers.append("Set-Cookie", "foo=bar"); headers.append("Set-Cookie", "baz=qux"); headers.getAll("Set-Cookie"); // ["foo=bar", "baz=qux"] Convert Headers to a plain JavaScript object.
About 10x faster than
Object.fromEntries(headers.entries())Called when you run
JSON.stringify(headers)Does not preserve insertion order. Well-known header names are lowercased. Other header names are left as-is.

Helper type for avoiding conflicts in types.
Uses the lib.dom.d.ts definition if it exists, otherwise defines it locally.
This is to avoid type conflicts between lib.dom.d.ts and @types/bun.
Unfortunately some symbols cannot be defined when both Bun types and lib.dom.d.ts types are loaded, and since we can't redeclare the symbol in a way that satisfies both, we need to fallback to the type that lib.dom.d.ts provides.
