How to fetch data from an API using express.js - express

Question

API
(https://api.mosmarts.com/truck/v0/api.php)
The API is scripted in PHP and accepts GET & POST commands and in return it responds back with a JSON response data.
To retrieve data the API requires “functionality” and “action” among other params as show below.
Command for retrieving all truck
Command for retrieving all truck
Payloads
{
"functionality" : "get",
"action" : "get_all_truck"
}
Command to retrieving truck inspection details by id
Payloads
{
"functionality" : "get",
"action" : "get_inspection_history",
"truckId" : "1"
}
NB: you will get truckId from command "get_all_truck" above
What’s expected from you
As the software developer you are tasked to design and develop a web-based backend solution that will have:
Dashboard: -
• Retrieve and indicate total number of trucks
• Retrieve and indicate number of inspection repairs requested 2. List all Trucks: -
• Implement search option
Inspection List: -
• Implement filter by truck
i have some code using express.js bt i get is a 404 error, no data retrieved.
app.js
const apiCallFromRequest = require('./Request')
const apiCallFromNode = require('./NodeJsCall')
const http = require('http')
http.createServer((req, res) => {
if(req.url === "/request"){
apiCallFromRequest.callApi(function(response){
//console.log(JSON.stringify(response));
res.write(JSON.stringify(response));
res.end();
});
}
else if(req.url === "/node"){
apiCallFromNode.callApi(function(response){
res.write(response);
res.end();
});
}
// res.end();
}).listen(3000);
console.log("service running on 3000 port....");
NodeJsCall.js
const https = require('https');
_EXTERNAL_URL = 'https://api.mosmarts.com/truck/v0/api.php';
const callExternalApiUsingHttp = (callback) => {
https.get(_EXTERNAL_URL, (resp) => {
let data = '';
// A chunk of data has been recieved.
resp.on('data', (chunk) => {
data += chunk;
});
// The whole response has been received. Print out the result.
resp.on('end', () => {
return callback(data);
// console.log(JSON.stringify(data));
});
}).on("error", (err) => {
console.log("Error: " + err.message);
});
}
module.exports.callApi = callExternalApiUsingHttp;
Request.js
const request = require('request');
_EXTERNAL_URL = 'https://api.mosmarts.com/truck/v0/api.php';
const callExternalApiUsingRequest = (callback) => {
request(_EXTERNAL_URL, { json: true }, (err, res, body) => {
if (err) {
return callback(err);
}
return callback(body);
});
}
module.exports.callApi = callExternalApiUsingRequest;

Hey Gerald you can find a simple response for this kind of question on google.
if you are a real beginner I would propose you the Axios npm.
here is an example of a really simple GET request with axios.
axios.get('https://api.github.com/users/mapbox')
.then(response => {
console.log(response.data.created_at);
});
