Here is a snippet:

async function updateForm(data: FormData) {
"use server"
await updateTodo(data)
}

..from updatetodo.js

export async function updateTodo(data: FormData ) {
'use server'

const title = data.get("title")?.valueOf()
if (typeof title !== "string" title.length === 0)
throw new Error('title issues')

const uid = data.get("id")?.valueOf()
if (typeof uid !== "string" uid.length === 0)
throw new Error('uid issues')

await prisma.todo.update({ where: { id:uid }, data: { title } })
}

afterwards I have to refresh the browser for the new data to show in my UI?
