JSON in Gatsby with GraphQL

Question

I have one JSON file named Test.json with all data in it.

[  { "name" : "Margo",
     "birthDate": "1990.03.15",
     "timetable": [
       {"time": "8.00",
        "task": "toDoMargoElem1"},
       {"time": "9.00",
        "task": "toDoMargoElem2"}
   },
   { "name" : "Arthur",
     "birthDate": "1990.03.15",
     "timetable": [
       {"time": "8.00",
        "task": "toDoArthurElem1"},
       {"time": "9.00",
        "task": "toDoArthurElem2"}
   }
}

I'd like to use call data from component, so I tried to call GraphiQL. Code exporter gives me

const ComponentName = () => {
  const data = useStaticQuery(graphql`
    {
      allTestJson {
        edges {
          node {
            name
            timetable {
              time
              task
            }
          }
        }
      }
    }
  `)
  return <pre>{JSON.stringify(data, null, 4)}</pre>
}

In my component Mycomponent I did next

import React from 'react'
import {useStaticQuery, graphql} from 'gatsby'


export default function Sched() {
  const data = useStaticQuery(graphql`
  {
    allTestJson {
      edges {
        node {
          name
          timetable {
            time
            task
          }
        }
      }
    }
  }
  `)
  const results = data.allTestJson.edges.map (({node}) => {
    const {name, time, task} = node;
    return {
      name, 
      time,
      task
    }
  })
  return (<div>
    {results.map (({eventName, time, task})=> 
      <div key = {name}>
        {name}
        {time}
        {task}
      </div>
    )}
  </div>
 ) 
}

But as a result i see just construction like

<div> {name} </div>
<div> {name} </div>

How can I see {time, task}? Why map doesn't show all nodes of my objects?

Answer 1

Check the object desctructing

 const results = data.allTestJson.edges.map (({node}) => {
    const {name, time, task} = node; // check here
    const {name, timetable:{time, task}} = node; // this is an example of nested object destructing
    return {
      name, 
      time,
      task
    }
  })

Answer 2

time and task are inside timetable nested object so the resulting code should look like:

import React from 'react'
import {useStaticQuery, graphql} from 'gatsby'


export default function Sched() {
  const data = useStaticQuery(graphql`
  {
    allTestJson {
      edges {
        node {
          name
          timetable {
            time
            task
          }
        }
      }
    }
  }
  `)
 return data.allTestJson.edges.map (({node}) => {
    const {name, timetable} = node;
    return <div key = {name}>
        {name}

        {timetable.map(item=><div key={item.task}>{item.time},{item.task}</div>)}
      </div>
    
  })

}

birthday field is not being queried (I guess it's a typo) so add it in the correct position.
