# NasaGO
# Objective
The objective of this project is to create a go script that will fetch the latest image of the day from the NASA image of the day website.
Later, I will add the functionality to download the image and set it as the wallpaper automatically.
# Usage
To use this script, you will need to have go installed on your system. You can download it from [here](https://golang.org/dl/).
Once you have go installed, you can run the following command to get the image of the day:
```bash
go run main.go
```
# How it works
It is decomposed into two main parts:
1. Fetching the image of the day from the NASA website.
2. Downloading each image.
## Fetching the image of the day from the NASA website
To fetch the image of the day, I used the [colly library](https://github.com/gocolly/colly). This library is a fast and flexible web scraping framework. It is used to extract the links to each image of the day from the NASA website.
With the links, I can now request the images in high resolution from their own specific page.
## Downloading each image
To download the images, I used the [net/http](https://pkg.go.dev/net/http) library. This library is used to download the images from the links I extracted from the NASA website.
All I have to do is to send a GET request to the link and save the response body to a file that I name based on the title of the image.
# Future improvements
In the future, I will add the functionality to set the image as the wallpaper automatically with crontabs.
