R2 via worker Accept Range

Hello,
Does anyone have javascript code for accepting bytes ranges in worker for R2 ?

You could check out kotx/render
Specifically:

kotx/render/blob/master/src/index.ts#L229-L256


      
          // Range handling
          if (request.method === "GET") {
            const rangeHeader = request.headers.get("range");
            if (rangeHeader) {
              file = await env.R2_BUCKET.head(path);
              if (file === null)
                return new Response("File Not Found", { status: 404 });
              const parsedRanges = parseRange(file.size, rangeHeader);
              // R2 only supports 1 range at the moment, reject if there is more than one
              if (
                parsedRanges !== -1 &&
                parsedRanges !== -2 &&
                parsedRanges.length === 1 &&
                parsedRanges.type === "bytes"
              ) {
                let firstRange = parsedRanges[0];
                range =
                  file.size === firstRange.end + 1
                    ? { suffix: file.size - firstRange.start }
                    : {
