I tried this solution to fetch data from multiple apis with async await but the output is undefined, what could be going wrong?
const getData = async (jwt) => {
try {
const [response1, response2, response3] = await Promise.all(
[
fetch("http://localhost:3000/api/confirmed"),
fetch("http://localhost:3000/api/deaths"),
fetch("http://localhost:3000/api/recovered"),
],
{
method: "GET",
headers: {
"user-agent": "vscode-restclient",
"content-type": "application/json",
accept: "application/json",
authorization:
"Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwibmFtZSI6IkxlYW5uZSBHcmFoYW0iLCJ1c2VybmFtZSI6IkJyZXQiLCJpYXQiOjE1OTY1MDY4OTN9.KDSlP9ALDLvyy0Jfz52x8NePUejWOV_mZS6cq4-JZXs",
},
}
);
const { data1 } = await response1.json();
const { data2 } = await response2.json();
const { data3 } = await response3.json();
console.log(data1, data2, data3);
} catch (err) {
console.error(`Error: ${err}`);
}
};
getData();
Promise.all only accepts a single parameter, an array of promises. Your second parameter (the object with method and headers) is therefore simply ignored. That obect needs to be passed as a second parameter to the fetch function, not to Promise.all.
Try the following:
const getData = async (jwt) => {
try {
const fetchOptions = {
method: "GET",
headers: {
"user-agent": "vscode-restclient",
"content-type": "application/json",
accept: "application/json",
authorization:
"Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwibmFtZSI6IkxlYW5uZSBHcmFoYW0iLCJ1c2VybmFtZSI6IkJyZXQiLCJpYXQiOjE1OTY1MDY4OTN9.KDSlP9ALDLvyy0Jfz52x8NePUejWOV_mZS6cq4-JZXs",
},
};
const [response1, response2, response3] = await Promise.all(
[
fetch("http://localhost:3000/api/confirmed", fetchOptions),
fetch("http://localhost:3000/api/deaths", fetchOptions),
fetch("http://localhost:3000/api/recovered", fetchOptions),
],
);
const { data1 } = await response1.json();
const { data2 } = await response2.json();
const { data3 } = await response3.json();
console.log(data1, data2, data3);
} catch (err) {
console.error(`Error: ${err}`);
}
};
getData();
