Introduction

When working with databases or APIs, you often need to filter data based on certain conditions. This is especially true when you want specific results returned in response to a query. If you're using Node.js alongside the SheetDB library, you may wonder how to incorporate comparison conditions into your requests. The following guide will explain how you can efficiently do this, unlocking the full potential of your data queries.

Understanding Conditions in Requests

In standard HTTP requests to the SheetDB API, it's straightforward to add conditions like <, >, <=, and >= to filter your data. For instance, a request might look like this:

This shows that you want to retrieve data where the id is less than 3. However, the question arises: Is it possible to use these conditions in the SheetDB Node.js library as well? The good news is, yes, you can use these conditions similarly when making requests with the SheetDB Node.js client.

Implementing Conditions in SheetDB Node.js Library

Here’s how to implement conditions in your requests using the SheetDB Node.js library component. Below are the steps and examples for using the comparison operators effectively.

Setting Up Your Client

Before diving into conditional requests, ensure that you have initialized your SheetDB client correctly. This should typically look something like this:
