SWR and CRUD functionality?

Hey guys, I’m having a hard time figuring this one out. I am switching certain CRUD functionality that I used to provide with a token, but now I am using SWR. Here are the docs:

I’m working on refactoring the POST request that I passed with the token like I have here:

  const postArt = async (title, year, medium, url, price) => {
    const artBody = {
      title: title,
      year: year,
      medium: medium,
      poster: url,
      price: price
    }
    const response = await fetch(`${API}/chizetteart`, {
      method: "POST",
      mode: "cors",
      cache: "no-cache",
      credentials: "same-origin",
      headers: {
        "Accept": "application/JSON",
        "Content-Type": "application/json",
        "token": token
      },
      body: JSON.stringify(artBody)
    })
    if (response.status !== 200) {
      alert(`Unable to create this masterpiece!`)
    } else {
      alert(`Art Created!`)
    }
    setArtList([artBody, ...artList])
  }

But now, I have SWR calling the data and caching it in a higher level context:

import React, { createContext } from "react"
import useSWR from 'swr'

// Node API
// const API = process.env.REACT_APP_API
const API = 'http://localhost:3000'

export const ArtListContext = createContext()


export function ArtListProvider(props) {

  const fetcher = url => fetch(url).then(r => r.json())
  const { data } = useSWR(`${API}/chizetteart`, fetcher)

  return (
    <ArtListContext.Provider
      value={{ data }}
    >
      {props.children}
    </ArtListContext.Provider>
  )
}


And I am calling that data in the component that I want the admin to make a POST request with the token as a header. I am looking at the multiple arguments array but not quite sure how to get it done here:

Lines 47 - 66 — the logic to take from the form state and put into an object,
93 - 102 — the submit event listener, where I am trying to use the SWR hook mutate().

Any help would be much appreciated.
