[Meldiron]

Snippet:

    async onChange(event: any) {
      const file: File = event.target.files[0];

      const appwrite = new Appwrite();

      appwrite
        .setEndpoint("http://localhost/v1") // Your Appwrite Endpoint
        .setProject("dev"); // Your project ID

      try {
        await appwrite.account.createAnonymousSession();
      } catch (err) {
        //OK, account is set
      }

      appwrite.storage
        // @ts-ignore
        .createFile("bb", "unique()", file, undefined, undefined, (p) => {
          console.log("P", p);
        })
        .then((f) => {
          console.log(f);
        })
        .catch((err) => {
          console.error(err);
        });
    },
