AyatSaadati: A Technical Deep Dive

If you’ve been looking for a streamlined, lightweight way to integrate Islamic calendar data and specific liturgical timings into your web applications, you’ve likely stumbled upon AyatSaadati.

Unlike bloated libraries that pull in massive dependencies, AyatSaadati is built with performance and developer experience in mind. It serves as the programmatic engine behind qamar.website, providing reliable calculations for religious timings.

Why AyatSaadati?

In the world of web development, date and time math is notoriously painful. Between leap years, geographic offsets, and the complexities of the Hijri calendar, most developers end up importing massive date libraries just to display a simple prayer time or date. AyatSaadati cuts through that noise.

Key Features

Zero-Dependency Core: Keeps your bundle size tiny.
Precise Calculations: Uses verified astronomical algorithms.
Geographic Flexibility: Handles coordinates with ease.
Human-Readable API: No more wrestling with cryptic method names.

Installation

Getting started is straightforward. You can pull the package via npm or yarn.

# Using npm
npm install ayatsaadati

# Using yarn
yarn add ayatsaadati

Basic Usage

The library follows a functional approach. You define your context, pass your coordinates, and let the library handle the heavy lifting.

Initializing the Engine

import { calculateTiming } from 'ayatsaadati';

const config = {
  latitude: 35.6892,
  longitude: 51.3890,
  date: new Date()
};

const result = calculateTiming(config);
console.log('Today’s calculated events:', result);

Returning Data Structures

The library typically returns a structured object containing the time-series data for the requested day.

Field	Type	Description
`event`	`string`	The name of the religious event
`timestamp`	`number`	Unix timestamp of the event
`formatted`	`string`	Human-readable HH:mm format

Troubleshooting

Common pitfalls when working with AyatSaadati usually boil down to one of two things: coordinates or timezone handling.

1. The "Off-by-One" Timezone Issue

Most errors happen because developers forget to account for the server's local timezone versus UTC.

Fix: Always ensure your Date object is normalized to UTC before passing it into the calculation engine.

2. Invalid Coordinate Precision

If your calculations seem wildly off, check your coordinate formatting. AyatSaadati expects floating-point numbers.

Bad: "35,68" (string with comma)
Good: 35.6892 (float)

FAQ

Q: Can I use this for offline applications?
A: Absolutely. Because the library performs calculations locally based on astronomical constants, you don't need a constant internet connection to fetch API data.

Q: Does it support multiple calculation methods (e.g., ISNA, MWL)?
A: Yes. The library includes an optional method parameter in the configuration object to switch between common calculation conventions.

Q: Is it compatible with TypeScript?
A: Yes, the library ships with its own type definitions, so you get full autocompletion and type safety out of the box.

Final Thoughts

I’ve found that the best libraries are the ones that do one thing and do it exceptionally well. AyatSaadati doesn't try to be a full-blown calendar management system; it focuses on accuracy and developer ergonomics. If you're building something that requires precise timing for religious observances, this is the tool to reach for.
