Graphical interface, such as Adminer, or using the command line. The next thing we need to do is to create a database and a database table to work with.

To delete the public folder run the following command: rm -rf public Delete existing routes and create a new route for quotes #Īt this point, we will make some changes to the routes. We don’t need any CSS or js for the purpose of this tutorial as we will deal with JSON. Delete public folder #Īs we are building a REST API for quote in this Node.js tutorial with Express we will delete the public folder. The generated basic express app can be seen in this pull request. You should see the below output on your browser:
#NODEJS MYSQL INSTALL#
To quickly check the output execute the following: cd nodejs-mysql & npm install & DEBUG =nodejs-mysql:* npm start You can generate an express js app without any view engine for this Node.js MySQL tutorial with the following command: npx express-generator -no-view -git nodejs-mysql To set up express, we will use the express-generator. Given you have Node.js running (either on the machine or with Docker), we can start with setting up Express first: Setup Express js for Node.js MySQL tutorial # It will be best to read on REST verbs and run some cURL commands to POST APIs. Before diving deeper into the steps, I would really recommend you to take a refresher on REST(REpresentational State Transfer).
