sqliteHow can I use SQLite with JavaScript?


SQLite is a popular open source SQL database engine that can be easily used with JavaScript. It is a self-contained, serverless, zero-configuration, transactional SQL database engine.

Using SQLite with JavaScript is easy and can be done using the sql.js library. This library allows you to load an existing SQLite database file, execute SQL commands, and even create new databases.

For example, to open an existing SQLite database and execute a query, you can use the following code:

// Load the sql.js library
var sqlite3 = require('sql.js');

// Open a database
var db = new sqlite3.Database('mydb.sqlite3');

// Execute a query
db.each("SELECT * FROM mytable", function(err, row) {
  console.log(row.id, row.name);
});

The output of the above code would be:

1 John
2 Jane
3 Joe

The code can be broken down into the following parts:

  1. var sqlite3 = require('sql.js');: This loads the sql.js library, which provides the necessary functions to interact with SQLite databases.

  2. var db = new sqlite3.Database('mydb.sqlite3');: This opens an existing SQLite database file.

  3. db.each("SELECT * FROM mytable", function(err, row) {...});: This executes a query on the database and prints out the results.

For more information on using SQLite with JavaScript, please see the sql.js documentation.
