Setting up the vweb web server

We will set up the web server in the main.v file by performing the following steps:

1. To begin, import the vweb and sqlite modules, as shown in the following code:

   // file: main.v
   module main
   import vweb
   import sqlite

2. Next, we will create a struct, named App, which appears as follows:

   // file: main.v
   struct App {
       vweb.Context
   mut:
       db sqlite.DB
   }

   The preceding code shows the App struct, which holds vweb.Context along with fields such as the port field on which our app will be running and a mutable db field of the sqlite.DB type.

3. Next, we will modify the main function, which will appear as follows:

   // file: main.v
   fn main() {
       db := sqlite.connect('notes.db') or { panic(err) }
       db.exec('drop table if exists Notes')
       ...
