Like any kind of apps, there are difficult issues to solve when we write Node apps.

In this article, we’ll look at some solutions to common problems when writing Node apps.

Synchronous Requests in Node.js

We can make synchronous requests in Node apps with the sync-request package.

For instance, we can write:

const request = require('sync-request');

try {
  const res1 = request('GET', '/yrl1');
  const res2 = request('GET', '/url2');
  //...
} 
catch (e) {
  //...
}

We import the sync-request package an use its request function to make requests synchronously.

However, as usual, synchronous code is blocking, so it shouldn’t be used in production apps.

However, it may be good for scripts.
