Error: SQLite database file name must be specified

Question

Error: SQLite database file name must be specified

I'm currently working through this tutorial that guides us in building an app with next.js. The tutorial involves using sqlite and performing database testing. One of the key components of the tutorial is the 'database-test.js' file:

const sqlite = require('sqlite');

async function setup() {
    const db = await sqlite.open('./mydb.sqlite');
    await db.migrate({force: 'last'});

    const people = await db.all('SELECT * FROM person');
    console.log('ALL PEOPLE', JSON.stringify(people, null, 2));

    const vehicles = await db.all('SELECT * FROM vehicle');
    console.log('ALL VEHICLES', JSON.stringify(vehicles, null, 2));
}

setup();

Upon running $node database-test.js, I encounter the following error:

(node:26446) UnhandledPromiseRejectionWarning: Error: sqlite: filename cannot be null / undefined

I'm puzzled by the requirement to open a .sqlite file instead of a .db file. Despite verifying the correct path to the .sqlite file, I remain unsure about the cause of this error and how to resolve it. Unfortunately, I've been unable to find any further information or examples of the .open function.

Referencing @ANimator120's suggestion, I made a few adjustments. Utilize the require function as it operates on the server side. Begin by installing sqlite3 using npm i sqlite3. Next, include the path to your migrations folder if it is not located in the project root.

const sqlite3 = require('sqlite3');
const sqlite = require('sqlite');

async function openDb() {
  return sqlite.open({
    filename: './database.db',
    driver: sqlite3.Database,
  });
}

async function setup() {
  const db = await openDb();
  await db.migrate(
                    { 
                      migrationsPath: './src/migrations', //specify custom path for migrations
                      force: 'last' 
                    }
                  );

  const people = await db.all('SELECT * FROM Person');
  console.log('all person', JSON.stringify(people, null, 2));

  const vehicle = await db.all(`SELECT a.*, b.* FROM Person as a
  LEFT JOIN Vehicle as b
  ON a.id = b.ownerId
  `);
  console.log('all vehicles', JSON.stringify(vehicle, null, 2));
}

setup();

Everything seems to be functioning smoothly, at least from my perspective.

To utilize the open() method correctly, ensure that you have installed both sqlite and sqlite3 via npm. The proper way to implement the open() method is as shown below:

const sqlite = require('sqlite');
      const sqlite3 = require('sqlite3')
    const {open} = require('sqlite')

       async function openDB (){
    return open({
        filename : './mydb.sqlite',
        driver: sqlite3.Database
    })
}


async function setup(){
    const db = await openDB();
    await db.migrate({force : 'last'});
}

setup();

To start, ensure sqlite3 is installed by running the command npm i --save sqlite3 in your terminal.

In your JS file, replace your existing code with the following:

const sqlite = require('sqlite');
const sqlite3 = require('sqlite3');
const {open} = require('sqlite');

async function openDB (){
   return open({
      filename : './mydb.sqlite',
      driver: sqlite3.Database
   })
}


async function setup(){
    const db = await openDB();
    await db.migrate({force : 'last'});
}

setup();

However, when executing the command line

 const people = await db.all('SELECT * FROM Person'); console.log("ALL PEOPLE", JSON.stringify(people, null, 2));

, an error stating that the table 'Person' does not exist is displayed. To resolve this issue, I had to remove DROP TABLE Person; from the migration file.

It turns out that the tutorial was using sqlite 3.0.3. If you're using sqlite3, here is the proper way to use open() in this scenario:

import { open } from 'sqlite'
import sqlite3 from 'sqlite3'

// Remember to import or invoke this function in a different file
export async function openDB () {
  return open({
    filename: './mydb.sqlite',
    driver: sqlite3.Database
  })
}
