CRUD for browser js-ipfs

I have ipfs in browser.
I init ipfs

  let ipfs = await IPFS.create({
          repo: './fs',
          emptyRepo: true,
          start: true,
          Identity: {

          preload: {
            enabled: true
          EXPERIMENTAL: {
            pubsub: true,
          config: {
            Addresses: {
              Swarm: [
