Storing notes in SQL with SQLite3

To get started with more normal databases, let's see how to use SQL from Node.js. First, we'll use SQLite3, a lightweight, simple-to-set-up database engine eminently suitable for many applications.

Note

To learn about that database engine, visit http://www.sqlite.org/. To learn about the Node.js module, visit https://github.com/mapbox/node-sqlite3/wiki/API or https://www.npmjs.com/package/sqlite3.

The primary advantage of SQLite3 is that it doesn't require a server; it is a self-contained, no-set-up-required SQL database.

The first step is to install the module:

$ npm install sqlite3@3.x --save

SQLite3 database schema

Next, we need to make sure that our database is configured. We're using this SQL table definition for the schema (save this as models/schema-sqlite3.sql):

CREATE TABLE IF NOT EXISTS notes (
    notekey VARCHAR(255),
    title VARCHAR(255),

How do we initialize this schema before writing some code? One way is to ensure that the sqlite3...
