Vuejs3 came and if you are new then you must check below link:

  1. Vue 3 Tutorials

Friends now I proceed onwards and here is the code snippet and please use this carefully to avoid the mistakes:

1. Firstly friends we need fresh vuejs(Vue 3) setup with bootstrap 5, axios modules and for that we need to run below commands into our terminal and also w should have latest node version installed on our system:

npm install -g @vue/cli

vue create vuedemo

cd vuedemo

npm install bootstrap --save

npm install axios

npm run serve //http://localhost:8080/

2. Finally guys we need to add below code into our src/App.vue file to get final output on web browser:

 <div class="container p-5">
 <h1 class="text-center border-bottom pb-3 mb-3">Vue 3 Showing PostgreSQL Data Using NodeJS Express WEB API</h1>
  <table class="table table-hover table-bordered mt-5">
        <th scope="col">ID</th>
        <th scope="col">User Name</th>
        <th scope="col">Country</th>
     <tr v-for="user in users" :key="">
//importing bootstrap 5 and axios
import "bootstrap/dist/css/bootstrap.min.css";
import axios from 'axios'
export default {
  return {
 mounted () {
    //api caling
      .then((resp) => {
        this.users =;

Guy’s now we will do Nodejs setup and make WB API using express:

1. Guys first create empty folder name `nodebackend` inside your pc any drive and then please below commands to set node modules:

npm init  

npm i express 

npm i nodemon -D

npm i pg pg-hstore

npm i --save cors

2. Now guy’s inside your nodebackend/package.json file add below code:

  "name": "postgres",
  "version": "1.0.0",
  "description": "This is test project.",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "serve": "nodemon index.js"
  "author": "",
  "license": "ISC",
  "dependencies": {
    "cors": "^2.8.5",
    "express": "^4.17.1",
    "pg": "^8.7.1",
    "pg-hstore": "^2.3.4",
    "sequelize": "^6.6.5"
  "devDependencies": {
    "nodemon": "^2.0.12"

3. Now guy’s create `index.js` file inside nodebackend folder and add below code inside it:

const express = require('express');

//solve cors issue
const cors = require("cors");

const app = express();

const port = 5000;
const Pool = require('pg').Pool;
  //Enter here your Postres database details
const pool = new Pool({
    user: 'postgres',
    host: 'localhost',
    database: 'dbname',
    password: 'root',
    dialect: 'postgres',
    port: 5432
  //Database connection and also please create postgres database first
pool.connect((err, client, release) => {
    if (err) {
        return console.error(
            'Error acquiring client', err.stack)
    client.query('SELECT NOW()', (err, result) => {
        if (err) {
            return console.error(
                'Error executing query', err.stack)
        console.log("Connected to Database !")
app.get('/users', (req, res, next) => {
    console.log("TEST DATA :");
    pool.query('Select * from users')
        .then(testData => {

app.listen(port, () => {
  console.log(`Horror jassa app is running on port ${port}.`);

4. Now guy’s run below command to run NodeJS:

npm run serve

Now we are done friends also and If you have any kind of query or suggestion or any requirement then feel free to comment below.

Note: Friends, I just tell the basic setup and things, you can change the code according to your requirements. I will come with more demo which will helpful to all.
