expressjsHow can I use Express.js and SQLite together to develop a web application?

Express.js is a web application framework for Node.js and is used to build web applications. SQLite is a lightweight, server-less database system that can be used to store and manipulate data. The two can be used together to develop a web application by following the steps below:

1. Create a database using SQLite.

2. Install Express.js and create a project.

3. Connect to the SQLite database using the sqlite3 module.

Example code

const sqlite3 = require('sqlite3').verbose();
let db = new sqlite3.Database('./mydb.db', (err) => {
   if (err) {
      console.error(err.message);
   }
   console.log('Connected to the mydb database.');
});

Output example

Connected to the mydb database.

4. Create a web server using Express.js and set up routes to serve the web pages and handle requests.

5. Create an API using Express.js and use it to interact with the database.

6. Use the API to fetch data from the database and render it on the web pages.

7. Deploy the application on a web server.
