javascript - How can I use a buffer as image (without writing it as a file and read again)

Question

  buffer = canvas.toBuffer("image/jpeg");
  await fs.writeFileSync(id + ".jpeg", buffer);
  (async() => {
    var { media } = await client.uploadPhoto({
      photo: id + ".jpeg",
      caption: "",
      post: "feed"
    });
    console.log(`https://www.instagram.com/p/${media.code}/`);
  })();

First I create a buffer to write a file. Then I write it to the current path with the name of id. In the async function, I try to get a photo as id+"jpeg". However, I don't want to do that because I run it on a server. Servers do not have storages. So it gives an error. I need something like

...client.uploadPhoto({
          photo: buffer.toImage(),
          caption: "",
          post: "feed"
        });

Any help is appreciated. Thanks in advance... The API that I use is this
