Mutations in Sanity Studio v3

[irinainina]

Hello, I'm having trouble with Mutations in Sanity v3
How to rewrite the example mutations proposed in the documentation for the Sanity v3?
Function that works in the Sanity v2 for sending a POST request looks like this

const saveTitle = async (title) => {    
  const mutations = [
    {
      createOrReplace: {
        _id: '123',
        _type: 'article',
        title: title
      },
    },
  ];

  const url =
  `https://${projectId}.api.sanity.io/v2021-06-07/data/mutate/production`;

  const response = await fetch(url, {
    method: 'post',
    headers: {
      'Content-type': 'application/json',
      Authorization: `Bearer ${process.env.NEXT_PUBLIC_TOKEN}`,
    },
    body: JSON.stringify({ mutations }),
  });
  const result = await response.json();
};

There aren't any changes to the mutation API, so this should be the same as before.

Having said that - be careful about putting tokens with write access into a public javascript bundle (such as process.env.NEXT_PUBLIC_TOKEN), as those tokens will be readable by anyone with access to the source of the application.
