![]() ![]() In the previous tutorial, I compared how to access SQlite and PostgreSQL with Express to be able to write the same code to access both databases. I have already seen how to access a SQlite database, then PostgreSQL. Having written the code, let’s start the server.

Install SQLite3 packages: npm i sqlite3 -D. InitialisationĪt the terminal create a directory, and install the relevant packages:Ĭonst db = require ( 'better-sqlite3' )( 'chinook.db', exports. It covers data modeling, migrations and querying a database. However, the primary focus of this article will be how to use the sequelize. I’m using Manjaro Linux 21.2.6, node v16.13.2, npm v8.3.2, better-sqlite3 v7.5.3 and apollo-server v3.8.1. Quickstart In this Quickstart guide, you'll learn how to get started with Prisma from scratch using a plain TypeScript project and a local SQLite database file. In this tutorial I will be demonstrating how to build a simple contacts management web application using Node.js, Express.js, Vue.js in conjunction with the sequelize.js object relational mapper (ORM) backed by a SQLite database. It probably isn’t a great place to start though if you don’t understand the GraphQL fundamentals, in that case you might try Oh-so minimal GraphQL API example with Apollo Server first.Īll code can be found at the repo PreciousChicken/sqlite-graphql-apollo-server. This worked example is designed to mimic the tutorial as closely as possible - the queries and responses are almost exactly the same. As per the site I’m using the sample database chinook.db. The differences being I’m using the better-sqlite3 rather than the sqlite3 npm package 1 and I’m using a GraphQL API (powered by Apollo Server) to present the data (as opposed to console.log). This packages gives you basic access to an SQLite database. I would like to make this more interactive, so the javascript would read the generated data from the database and create statistics out of it. I can simply open this report locally (i.e. npm install -save oracledb Oracle Database. Run the list of commands below to install node-red-node-sqlite in your Node-RED user directory. Currently I have a tool which creates a report (a bunch of images, html files and an sqlite database). In this tutorial you will learn to make a simple setup of Sequelize. Having SQLite installed in your Raspberry Pi. This worked example builds on their Querying Data in SQLite Database from Node.js Applications tutorial. Follow this next tutorial to learn how to Install SQLite database on a Raspberry Pi. The website has some good pointers on using the SQLite database. ![]()
