I will show you how to build a CRUD application with a full stack example. The back-end server and front-end side use the same programming language.

The JWT Authentication & Authorization example is an example.

One place to run both projects.

How to serve/combine Vue App with Express

Serverless with Firebase:

– Vue Firebase Realtime Database: CRUD example

– Vue Firestore: Build a CRUD App example

An example of Vue.js and Express.

A full-stack application will be built in that.

  • Tutorial has id, title, description, published status.
  • User can create, retrieve, update, delete Tutorials.
  • There is a search box for that.

Here are screenshots of the example.

– Add an object:

– Show all objects:

Click on the button to change the object.

On this Page, you can:

You can change the status using the Publish button.

The button is used to remove the object from the database.

This object’s details can be updated with the Update button.

– Search objects by field ‘title’:

Full-stack CRUD App Architecture

We’re gonna build the application with following architecture:

The Node.js Express interacts with a database using an ORM.

Axios is used to consume data on the components how to learn mobile app development. The Vue Router is used for navigation.

Node.js Express Back-end

The Node.js Express App will use these.

Methods Urls actions get all Tutorials, get all posts, get all updates, get all warnings, get all warnings, get all warnings, get all warnings, get all warnings, get all warnings, get all warnings, get all warnings, get all warnings, get all warnings.

Project Structure

The db.config.js is exported.

The Express web server is in server.js.

Next, we create a Sequelize data model in models.

– Tutorial controller in controllers.

There are routes for handling all CRUD operations.

Please visit if you want to use raw SQL without Sequelize.

Build Node.js Rest APIs with Express & MySQL

This backend works well with the back end.

Implementation

Create Node.js App

First, we create a folder:

$ mkdir nodejs-express-sequelize-mysql $ cd nodejs-express-sequelize-mysql

The Node.js App has a package.js file.

The name is npm and the version is 1.0.0.

The necessary modules are express, sequelize, and body-parser.

Run the command:

npm install express sequelize mysql2 body-parser cors –save

Setup Express web server

In the root folder, we can create a server.js file.

const express, const bodyParser, const cors, const app, and var corsOptions are all related.

What we do are:

– import express , body-parser and cors modules:

  • Express is for building the Rest apis
  • The req.body object can be created with the help of body-parser.

object cors provides Express to enable CORS.

Add body-parser and cors middlewares using the app.use method. The origin is: http://localhost:8081.

A simple test route is defined.

– listen on port 8080 for incoming requests.

The app can be run with the command.

You can open your browser by clicking on the link:

The first step is over. We are going to work with Sequelize.

Configure MySQL database & Sequelize

In the app folder, we create a separate folder for the configuration of the app.

HOST: “localhost”, USER: “root”, PASSWORD: “123456”,DB: “testdb”, dialect: “mysql”, pool: max: 5, min: 0, acquire: 30000

First five parameters are for MySQL connection.

The pool will be used for the Sequelize connection pool configuration.

max : maximum number of connection in pool

Minimum number of connections in pool.

The maximum time that a connection can be in the pool is milliseconds.

The maximum time that a pool can try to get a connection before throwing an error is milliseconds.

You can visit the reference for the Sequelize constructor.

Initialize Sequelize

Sequelize is going to be put in the app/models folder.

Now create app/models/index.js with the following code:

“Require”, “sequelize”, and “const sequelize” are some of the terms used in the definition of “Require”, “sequelize”, and “const sequelize”

Don’t forget to call sync() method in server.js:

The const app is as follows: app.use(…); const db is as follows: require(…)

Force is true as following code:

“Drop and re-sync” is what the console.log says.

Define the Sequelize Model

In models folder, create tutorial.model.js file like this:

module.exports is a part of the module.

The model represents a table in a database. The columns will be created automatically.

After initializing Sequelize, we don’t need to write functions anymore.

  • create a new Tutorial: create(object)
  • find a Tutorial by id: findByPk(id)
  • get all Tutorials: findAll()
  • The data is where: id:.
  • remove a Tutorial: destroy(where: { id: id })
  • remove all Tutorials: destroy(where: {})
  • You can find all the videos by title.

These functions will be used in our Controller.

We can make the example better by adding comments. The One-to-Many Relationship is a topic I write about at:

Sequelize Associations: One-to-Many example – Node.js, MySQL

You can add tags for each tutorials and tags for the many to many relationship.

Sequelize Many-to-Many Association example with Node.js & MySQL

Create the Controller

Inside the app/controllers folder, let’s create aController.js.

  • create
  • findAll
  • findOne
  • update
  • delete
  • deleteAll
  • findAllPublished

“Require(“../models)”); “Require(“../tutorials)”; “Require(“..Sequelize.Op)”; “Require(“..Sequelize.Op)”; “Require(“..Sequelize.Op)”.

You can implement this app step by step.

An example with Express, Sequelize and MySQL.

Run the Node.js Express Server

You can run our application with the command.

The console shows:

There is a server running. If the table does not exist in the first place, then create it if it does exist in the second place.

Vue.js Front-end

There is an App component. It has a way to find routes.

– TutorialsList component gets and displays Tutorials.

The component has a form for editing the details.

There is a form for submission of a new Tutorial.

These components use axios to make and receive requests.

Technology

  • vue: 2.6.10
  • vue-router: 3.1.3
  • axios: 0.19.0

Please visit if you want to use Vue 3.

There is a CRUD example with the Axios.

Project Structure

The package contains 3 main modules.

There are three components.

– router.js defines routes for each component.

The http-common.js is used for axios.

There are methods for sending requests to the anis.

– vue.config.js configures port for this Vue Client.

Implementation

Setup Vue.js Project

Go to the folder you want to save the project folder in.

vue create vue-js-client-crud

Choose the default option and you will see options.

The process is over. New folders and files are created by us.

Open public/index.html, add bootstrap inside tag:

title>vue-js-client-crud/title>,,,,,,,,,,,,,,,,,,,,

Add Vue Router to Vue.js 2 CRUD App

– Run the command: npm install vue-router .

In the folder, create a new Router.js and define it as follows:

export default new Router, path: “/”, name: “/tutorials”

– Open src/main.js, then import router :

import Vue from ‘vue’ import App from ‘./App.vue’ import routers from ‘./router’

The app component is the root container for our application, it will have a navigation bar.

nav class=”navbar-expand-navbar-dark bg-dark” class “navbar-brand”

Initialize Axios for Vue.js 2 CRUD HTTP Client

Npm will be used to install axios.

Under the folder, we create a file like this:

export default axios from “axios”

It depends on the url that your server uses.

Create Data Service

The service will use axios from the client.

return http.get(“/tutorials”), get(id), create(

Create Vue Components

We have 3 components that are related to 3 routes.

  • Add new Item
  • List of items
  • Item details

You can follow the steps in the post.

Vue.js CRUD App with Vue Router & Axios

Or using a data-table example.

Run Vue.js Client

You can run our app with a command.

If the process is successful, you can open the browser and check it.

Source Code

You can find the Github source code for this topic.

Conclusion

There is an overview of a full-stack CRUD App.

We take a look at the client-server architecture and the project structure for building a front-end app.

You will learn more about how to implement the system.

One place to run both projects.

How to serve/combine Vue App with Express

You can get a typescript version for the app.

There is a typescript CRUD application that can be used.

There is server side pagination in Node.js.

There is a server side pagination example.
