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.

Once you have go installed, you can run the following command to get the image of the day:

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. 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 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.
