SkyBot

Hi there, welcome to SkyBot repository!

SkyBot is a user-friendly and straightforward implementation designed for retrieving astronomical transits based on specific parameters for astrology applications. This project was built to provide astrology enthusiasts, developers, and businesses with accurate astrological data for their applications (yep, it is free and open-source!).

Also, this API might be used for scientific purposes too, since the astronomical data it provides comes from Moshier's Ephemeris algorithms.

This work is derived from CircularNatalHoroscopeJS (v1.1.0). I just wrapped it into an API that can be deployed on Docker containers. There are no relevant changes to the main algorithm but I decided not to make use of the origin library as a module so SkyBot can incorporate updates and extension in the future without relying in the origin project.

Key Features

SkyBot inherits all the features of the CircularNatalHoroscopeJS v1.1.0, but was built with containerization in mind, so these are the actual features:

Allows user to switch between tropical and sidereal zodiacs when constructing calculations;
Calculates the major angles (ascendant and midheaven) in relation to the point of origin;
Calculates the positions for all major bodies (sun, moon, mercury, venus, mars, jupiter, saturn, uranus, neptune, pluto, chiron, sirius) in relation to the point of origin;
Calculates the positions of the north/south Lunar Nodes and Lilith in relation to the point of origin;
Notes whether a planet is in retrograde at the given date/time;
Provides the cusps of each house in relation to the point of origin within multiple house systems (placidus, koch, topocentric, regiomontanus, campanus, whole-sign, equal-house);
Provides the cusps of each astrological sign in relation to the point of origin;
Provides a configurable list containing all the computed major and minor aspects of all bodies / points / angles;
Provides a way to extend the project with other language and deliver language-specific labels and names within the results (SkyBot added Brazilian Portuguese);
Docker Container Compatibility: SkyBot allows seamless deployment and scalability within Docker containers. This ensures easy integration into various environments;
JWT Token Authentication: Adds an extra layer of security to the API and allows future extension into a multi-user API.

Future Work

The current version uses an SQLite database in memory to store user credentials, in the future SkyBot can be extended to support multiple users, move the SQLite database to disk and store usage information for each user, making possible to set limits per user and quantify some metrics;
Validate query parameters;
Implement customOrbs query parameter.
Implement JWT authentication using RSA-signed tokens.

How to Run SkyBot?

Using Docker

This project is designed to run in Docker containers. To configure the application and build the Docker image, use the build.sh script:

./build.sh -u <username> -p <password> -a <app-port>

Parameters:

-u or --username: Provide the username for the application.
-p or --password: Provide the password for the application.
-a or --app-port: Specify the port on which the application will run.

Example:

./build.sh -u your_username -p your_password -a 3000

Please note that you need to replace <username>, <password> and <app-port> with your actual values. After building, you need to deploy a container and route the ports, to make it easier you can run the deploy.sh script:

./deploy.sh -p <app-port>

Parameters

-p or --app-port: Specify the port on which the application will run. It routes from container to host.

NOTE: You don't need to use the build.sh and deploy.sh scripts, they are there just to make things easier, but if you know what you're doing you can build and deploy without them.

Without Docker

If you don't want to run the app in a Docker container, you can run it in the host machine by following these steps:

Install dependencies:

npm install

Configue the app:

npm run setup <username> <password> <app-port>

The setup script creates a .env file containing the encrypted password and other important app variables, like the APP_KEY (which is used to generate JSON Web Tokens). If you know what you're doing, you can edit the .env file manually.

Build the app:

npm run build

After building, you can run it from the dist folder:

npm run dist

By doing so, the SkyBot starts running on port 8080 (you can change in the .env file). Now you are free to setup your production environment the way you want or just start having fun!

Using the API

With SkyBot running you have the following API routes:

Login

Endpoint to authenticate a user and obtain a JSON Web Token (JWT).

URL: /login
Method: POST

Request:

Content-Type: application/json

Body:

 {
 	"username": "example_user",
 	"password": "secure_password"
 }

Response:

Status: 200 OK

 {
 	"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
 }

Status: 401 Unauthorized
```
 {
 	"error": "Unauthorized"
 }
```

Status: 500 Internal Server Error

 {
 	"error": "Internal Server Error"
 }

Description:
- Validates user credentials against the stored hash in the database.
- Issues a JWT token with a 1-hour expiration upon successful authentication.
- Returns appropriate error responses for failed authentication or internal errors.
