Unlock the Power of Universal Database Layering with nanoSQL
Imagine being able to switch between different databases without having to learn new query languages. Sounds too good to be true? Thanks to nanoSQL, a JavaScript database layer library, this is now a reality. In this tutorial, we’ll explore the world of nanoSQL and show you how to build a simple to-do backend app using this powerful tool.
What is nanoSQL?
nanoSQL is a standardized query language that allows you to interact with multiple databases, including MySQL, MongoDB, indexedDB, and Redis, to name a few. Its identical API makes it easy to migrate to other databases without having to rewrite existing queries. Whether you’re working with relational database management systems (RDBMSs) or NoSQL databases, nanoSQL has got you covered.
Building a Simple To-Do Backend App
To demonstrate the power of nanoSQL, we’ll build a simple to-do backend app using MongoDB as our database layer. Don’t worry if you’re new to MongoDB; we’ll guide you through the process.
Setting Up the Project
First, let’s set up our project structure and install the necessary dependencies. We’ll create a new project folder and initialize it using Node.js. Next, we’ll install the required dependencies, including nanoSQL.
Creating the Backend API
Our backend API will consist of five routes: /
returns a list of to-dos, /:id
returns a single to-do, /del/:id
deletes a single to-do, /update/:id
updates a single to-do, and /delete
deletes all to-dos.
Building Database Handlers
Our database handlers will be responsible for carrying out CRUD (Create, Read, Update, Delete) operations. We’ll create a database.js
file that will contain our database object, which will include methods for each CRUD operation.
Querying with nanoSQL
nanoSQL uses a standardized query language that makes it easy to perform data operations. We’ll define a retrieve
method that returns a single to-do item, a retrieveAll
method that returns a list of all to-dos, an insert
method that adds a new to-do item, an update
method that updates a single to-do item, and a delete
method that deletes a single to-do item.
Connecting the Database to API Routes
Now that we have our database handlers in place, let’s connect them to our API routes. We’ll update our app.js
file to include the necessary logic for each route.
Testing the API with Postman
It’s time to put our API to the test! We’ll use Postman to verify that our API is working as expected. We’ll start by retrieving the list of to-dos, then add a few new to-dos, update an existing to-do, and finally, delete a to-do item.
The Power of nanoSQL
With nanoSQL, you can switch between different databases without having to learn new query languages. Its standardized query language makes it easy to migrate to other databases, reducing the time and effort required to develop and maintain your application.
