Function fetchTileJSON

fetchTileJSON(
    url: string,
    options?: {
        fetch?: {
            (input: URL | RequestInfo, init?: RequestInit): Promise<Response>;
            (input: string | URL | Request, init?: RequestInit): Promise<Response>;
        };
    },
): Promise<TileJSONSpecification>
Download a TileJSON document and make its relative tiles[] entries absolute.

osm() and satellite() do no I/O, so this is how you obtain a TileJSON when the style needs one at build time — to inline it via urls, or to inspect it with osm.languages(). To resolve an already-built style instead, use inlineSources().
