How to Make API calls in express server - node.js

Question

I am trying to make a get request in an express server, currently the server simply prints all post requests and it works fine up to that, the issue is when GET request is made the response is returned as 'undefined'
var env = process.env.NODE_ENV || "development";
var config = require("./config")[env];
const express = require("express");
const bodyParser = require("body-parser");
const axios = require("axios");
const app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
const hostname = config.server.host;
const port = config.server.port;
app.post("/", (req, res) => {
console.log(req.body);
res.sendStatus(200);
axios
.get("https://reqres.in/api/products/3")
.then(response => {
console.log(response);
})
.catch(error => {
console.log(error.response);
});
});
app.listen(port, hostname, () =>
console.log(`Server running at http://${hostname}:${port}/`)
);

Answer 1

Use Postman to send Api calls to the server. I am attaching the link down below.
Install Postman chrome extension, if you're using chrome.
Use the Localhost:port server and post method and add variable to post your query
Hope this helps.
Moreover, Just add this tweak in your code and listen on a proper localhost,
var env = process.env.NODE_ENV || "development";
var config = require("./config")[env];
const express = require("express");
const bodyParser = require("body-parser");
const axios = require("axios");
const app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
const hostname = config.server.host;
const port = config.server.port;
app.post("/", (req, res) => {
console.log(req.body);
res.sendStatus(200);
axios
.get("https://reqres.in/api/products/3")
.then(response => {
console.log(response);
})
.catch(error => {
console.log(error.response);
});
});
app.listen(1337, function(){
console.log('Express listening on port', this.address().port);
});

Executed the below code
axios .get("https://reqres.in/api/products/3")
.then(response => { console.log(response); })
.catch(error => { console.log(error.response); })
Its executed and working fine.
My Guess is that in your case its going to catch block
Change the following line
.catch(error => {
console.log(error.response);
});
TO
.catch(error => {
console.log(error);
});
And see whether some error is printing.No response object is assigned to error, that may be u r receiving undefined
