TypeScript NextJS destructuring-CodePudding

I have object from postgresql:

Need to get id, name and content on NextJS component like that:

export async function getServerSideProps() {
  const data = await prisma.note.findFirst()
  return {
    props: {
      userNote: data,
    },
  }
}
interface INote {
  id: number
  name: string
  content: string
}

const Home = ({ name, content, id }: INote) => {
  console.log(name)
  return <div>hello world</div>
}

but i got undefined. What's wrong?

CodePudding user response：

The problem is that your props in the Home component are not

{
  id: number
  name: string
  content: string
}

but actually,

{
 userNote: {
  id: number
  name: string
  content: string
 }
}

You'll either need to change your destructuring and the type:

const Home = ({ userNote: { name, content, id } }: { userNote: INote }) => {

or you could change your getServerSideProps:

export async function getServerSideProps() {
  const data = await prisma.note.findFirst()
  return {
    props: data,
  }
}

In my experience it's more idiomatic to go with the first approach and change it to:

export async function getServerSideProps() {
  const data = { id: 1, name: 'test', content: 'content' }
  return {
    props: {
      userNote: data,
    },
  }
}

interface INote {
  id: number
  name: string
  content: string
}

interface HomeProps {
   userNote: INote
}

const Home = ({ userNote: { name, content, id } }: HomeProps) => {
  console.log(name)
  return <div>hello world</div>
}

export default Home
