# F95API

Unofficial Node JS module for scraping F95Zone platform

These APIs have been developed to support [this application](https://github.com/MillenniumEarl/F95GameUpdater) and allow you to obtain data on games and mods on the platform [F95zone](https://f95zone.to/) (**NSFW**)

A simple usage example can be found in [app/example.js](https://github.com/MillenniumEarl/F95API/blob/master/app/example.js)

**Attention**: Two-factor authentication is not supported

# Data scraping
Games/mods can be obtained by name or URL

```javascript
// The name is case insensitive
let listOfFoundGames = await F95API.getGameData("your game name");
let listOfFoundMods = await F95API.getGameData("your mod name", true);

let specificGame = await F95API.getGameDataFromURL("the URL of your game");
```

While user data (after authenticating) with 

```javascript
let authResult = await F95API.login(username, password);

let loggedUserData = await F95API.getUserData();
```

# Classes
## Games and mods
Information about games and mods is stored in a GameInfo object with the following fields:

```
name: The game name
author: The game developer
url: The URL that leads to the game thread on F95Zone
overview: Description of the game
language: Main language of the game
supportedOS: List of supported OS (Windows/Linux/Mac/Android...)
censored: Are the NSFW parts censored?
engine: Game engine (Unity, Ren'Py, RPGM...)
status: Completed/Abandoned/Ongoing/Onhold
tags: List of tags
previewSrc: Source URL of the game description image
version: Version of the game
lastUpdate: Date of the last update (it's a Date object)
isMod: Is it a game or a mod?
changelog: Latest changelog available
```

The serialization in JSON format of this object is possible through `JSON.stringify()` while the deserialization must happen through the static method `GameInfo.fromJSON()`.

## User data
User data (after authentication) can be stored in a UserProfile object, consisting of the following fields:

```
username: Name of the logged in user
avatarSrc: Source URL of the user's profile picture
watchedGameThreads: List of URLs of threads followed by the user
```

## Login results
The outcome of the authentication process is represented by the LoginResult object:

```
success: Was the authentication successful?
message: Possible error message (unrecognized user, wrong password...) 
         or authentication successful message
```

# Logging
To log the behavior of the application [log4js](https://github.com/log4js-node/log4js-node) is used with a default level of "warn". This option can be changed with the `loggerLevel` property.

# Guidelines for errors

- If you can, return a meaningful value
- Return `null` only if the function should return a complex object (including strings)
- Return an empty array if the function should return an array
- Return `false`, `-1` when the function should return `boolean` or `number`
- Throw an exception only if it is an error or if a wrong value could mess up the functioning of the library
