How to pass fetched API data to HTML table

Question

I have a google-map with customized markers. Those markers are logos of companies. After inquiring the APIs I am able to obtain a json file with the vessels I am interested in.

The problem I have is that I have been trying to inject these vessels into a table on the user interface, without success unfortunately. How to do that?

Below the typical response from the API

[  
    {  
        "AIS":{  
            "MMSI":227441980,
            "TIMESTAMP":"2017-08-11 11:17:37 UTC",
            "LATITUDE":46.1459,
            "LONGITUDE":-1.16631,
            "COURSE":360.0,
            "SPEED":0.0,
            "HEADING":511,
            "NAVSTAT":1,            
            "IMO":0,
            "NAME":"CLEMENTINE",
            "CALLSIGN":"FJVK",
            "TYPE":60,
            "A":0,
            "B":0,
            "C":0,
            "D":0,
            "DRAUGHT":0.0,
            "DESTINATION":"",
            "ETA_AIS":"00-00 00:00",
            "ETA":"",
            "SRC":"TER",
            "ZONE": "North Sea",
            "ECA": true      
        }
    }
]

Below the code I am using to inject the value from the API fetch into the Table:

ShipTracker.js

import React from 'react';
import { Table } from 'reactstrap';

const shipCompanyMap = {
    MICHIGAN: 'DONJON',
    ATLANTIC SALVOR': 'DONJON',
    STUYVESANT: 'DUTRA'
};

const Ship = ({ ship, logoMap, logoClick }) => {
const shipName = ship.AIS.NAME;
const company = shipCompanyMap[shipName];
const img = logoMap[company && company.split(' ').join('').toUpperCase()];
return (
    <div onClick={(event) => logoClick(event, ship)}>
        {/* Render shipImage image */}
        <img src={img} alt="Logo" />
    </div>
);
};
export { Ship };

const ShipTracker = ({ ships, setActiveShip }) => {
console.log('These are the ships: ', { ships });

return (
    <div className="ship-tracker">
        <Table className="flags-table" responsive hover>
            <thead>
                <tr>
                    <th>#</th>

                </tr>
            </thead>
            <tbody>
                {ships.map((ship, index) => {
                    // const { IMO, NAME, CALLSIGN, HEADING, SOG, MMSI, LONGITUDE, LATITUDE } = ship;
                    // const cells = [ NAME, CALLSIGN, HEADING, SOG, IMO, MMSI, LONGITUDE, LATITUDE ];

                    const {
                        MMSI,
                        TIMESTAMP,
                        LATITUDE,
                        LONGITUDE,
                        COURSE,
                        SPEED,
                        HEADING,
                        NAVSTAT,

                    const cells = [

                        NAME,
                        CALLSIGN
                    ];

                    return (
                        <tr
                            onClick={() => setActiveShip(ship.AIS.NAME, ship.AIS.LATITUDE, ship.AIS.LONGITUDE)}
                            key={index}
                        >

                            {cells.map((cell) => <td key={ship.AIS.MMSI}>{cell}</td>)}
                        </tr>
                    );
                })}
            </tbody>
        </Table>
    </div>
);
};

export default ShipTracker;

The file GoogleMap.js below is carrying <ShipTracker /> information:

class BoatMap extends Component {
    constructor(props) {
        super(props);
        this.state = {
            buttonEnabled: false,

        );
    }
}

I have been researching a lot and came across this source and this other source which were useful but didn't solve the problem. Am I maybe misunderstanding the response of the API and how to inject the data?

Thanks for pointing in the right direction for solving this issue.

Answer 1

You just need to go one level deeper on your destructuring:

If you log ship , it will be an object looking like this {AIS: {...}} . So, change this: const {MMSI, ... } = ship to const {MMSI, ... } = ship.AIS .
