In my previous podcast entitled Using VS Code's REST Client extension instead of Postman, I discussed using a GET request with VS Code's REST Client extension in a production environment. Now I will discuss using a POST request in a local environment.

First I had to add the following to my file (I found out that if I added the .rest extension, it would recognize the http language by default):

@hostname = localhost
@port = 3000
@host = {{hostname}}:{{port}}
@contentType = application/json

# POST /users
POST http://{{host}}/users HTTP/1.1
Content-Type: {{contentType}}

    "name": "Michael",
    "email": "",
    "age": 23,
    "password": "1234567"

The http code in is available for viewing in the transcript post of this podcast episode on

This code differs from the previous request code in a couple of ways. First of all, it is a POST request instead of a GET request. Second of all, the environment is local. And third of all, I am using environment variables here.

And this is what I had in my index.js (my Express server file):

const express = require('express')
const app = express()
const port = process.env.PORT || 3000
const User = require('./models/user')

express will automatically parse incoming json
to an object so we can access it in our request handlers
We can do that using req.body
app.use(express.json())'/users', (req, res) => {
	const user = new User(req.body)
	    .then(() => {
	    .catch(() => {})
app.listen(port, () => {
    console.log(`Server is running on Port ${port} ...`)

When I clicked on "Send Request" located right above POST, The following was returned in the Response:

HTTP/1.1 200 OK
X-Powered-By: Express
Content-Type: application/json; charset=utf-8
Content-Length: 119
ETag: W/"77-tTFyEkK9sxYeShiMfIo+M6HknHI"

Connection: close

  "age": 23,
    "_id": "5f58b8dbc3c61a59129690ff",
  "name": "Michael",
  "email": "",
  "password": "1234567",
  "__v": 0

And the following was returned in the mongo shell:

{ "_id" : ObjectId("5f58b8dbc3c61a59129690ff"), "age" : 23, "name" : "Michael", "email" : "", "password" : "1234567", "__v" : 0 }

And that is it! Well, you get the idea.

Just make sure that the server is running. Sometimes you may think that it is because you are sure you started running it a little while before, but for whatever reason, you might end up getting inadvertently disconnected (or perhaps you disconnected the server and forgot!). It is important to check whether the server is running before clicking on Send Request.

In order to make sure you are actually connected to the server via the REST Client, make sure that "port" has been selected with It should look something like this:

The reason why this is possible is because I created some environment variables including for the port. And that's what makes it possible for me to connect via localhost while the server is running on the same port as I define in my file.

And that is it!

I will be embedding this episode of Plugging in The Holes along with a transcript in the form of a post on for your hearing and reading pleasure. Bye for now!
