That’s all we need to do r to connect our Node.js web server with MySQL database. In the end, we set the server to listen at Port 3000.This table will have the attributes “id”, “name”, and “designation.” For the last step, we pass this query to the query() method and the query executes.Īpp.get('/createemployee', (req, res) => ` Ĭonsole.log('Server started on port 3000') After the database is created, create a table called “employee” to store the employee details into the database.The latter throws an error if the query wasn’t successfully executed. We then pass this query to the query() method along with the error callback method. Notice that we have first defined the SQL query for creating the database. We use the GET API request to create the database.

Since we are using the Express module to create the web server, we create a variable named app that behaves as an object of the express module.This method will also throw an error if any issues arise while connecting to the MySQL database. Now that we have created the bridge between Node.js and MySQL, let’s use the connect() method to actually connect to the database.

Host: Specifies the host that runs the database.

We define the following parameters, which in turn facilitates proper connection to the database.

After we add the modules, we use the createConnection() method to create a bridge between the Node.js and MySQL.

We can add these modules using the terminal inside VSCode.

We are importing a couple of modules that we will need in the application: express, and mysql.

So let’s go ahead and explore what each snippet of code does in this file. Since our main goal is to understand the connection between Node.js and MySQL database, this will be the only file that we create and work on in this project. We are working only on a single file called index.js, so the project directory is very simple.Ĭreate a file called index.js in the project directory. Let’s first take a look at how the project directory should look at the end of this tutorial. Learn to build network applications quickly and efficiently using JavaScript with the Node.js Training. We will be able to create, update, and delete employees in the database. The code that we’re writing now will allow us to create the employee database. We are going to connect the Node.js web server with the MySQL database to store the employee details. Press Enter to leave the default settings as they are.

Open the newly created directory in VS Code inside the terminal, and type npm init to initialize the project.

Create an empty folder and name it node.js mysql.

To download the application, go to its official website.

#Nodejs mysql install

Then, open the installer to install MySQL on your system, keeping the default settings.įor this tutorial, we are using the Postman application to work with the API requests in our code. Similar to Node.js installation, you can download the MongoDB Community Server from its official website. We are using Visual Studio Code in this tutorial, but you can also use other editors-like Atom and Sublime Text-if you are more comfortable with them.įig: Visual Studio Code download page MySQL Installation Verify whether it is installed or not with the following command in CMD: npm -version NPM includes many libraries that are used in web applications such as React. When we install Node.js, we gain access to NPM (Node Package Manager). Verify that Node.js was properly installed by opening the command prompt and typing this command: node -versionĤ. The installer will install Node.js and prompt you to click on the finish button.ģ. You can leave the other settings in default mode.
