### Requirements

- [Node](https://nodejs.org) 8.14+
- [Yarn](https://yarnpkg.com) 1.12+

### Installation

Clone the repo:

```bash
> git clone https://github.com/Alamantus/little-library.git
```

Navigate to the folder:

```bash
> cd path/to/little-library
```

Run `yarn` to install all the dependencies:

```bash
> yarn
```

Then copy `settings.example.json` to `settings.json` and make sure everything is to your liking. Below is the default `settings.example.json` file:

```js
{
  "port": 3000, // The server's port
  "siteTitle": "Little Library",  // The name that appears in the site header
  "titleSeparator": " | ",  // The separator for the browser bar's title between page and site titles
  "fileLocation": "./public/files/",  // The relative path to where the ebook files will be served from
  "historyLocation": "./public/history/", // The relative path to where the history metadata files will be served from
  "maxLibrarySize": 0,  // The maximum number of books that can be added to the library. 0 means unlimited
  "maxFileSize": 0, // The maximum file size of an ebook allowed to be uploaded. 0 means unlimited
  "maxHistory": 0,  // The maximum number of history metadata files that will be saved on your server. 0 means unlimited
  "allowedFormats": [".epub", ".mobi", ".pdf"], // The file formats allowed to be uploaded
  "backupPassword": "password",  // The plaintext password that allows you to access the /backup features. Be sure to change this before going live!
  "hideVisitors": false,  // If true, the "Current Visitors" counter will not update on the front end
  "sslPrivateKey": null,  // The ssl private key received from your certificate authority for HTTPS support
  "sslCertificate": null, // The ssl certificate received from your certificate authority for HTTPS support
  "sslCertificateAuthority": null,  // The ssl certificate authority (CA) received from Let's Encrypt for HTTPS support
  "forceHTTPS": false // Redirect all traffic for http to https (not sure why you wouldn't want this)
}
```

### Usage

Run `npm start` to start the Little Library server:

```bash
> npm start
```

Navigate to `localhost:3000` in your favorite browser to see the Little Library.

The Little Library allows anyone with access to it to give or take ebooks. I'll write a more in-depth bit about how exactly to use it when I have some more time.

### Management

There is a backup utility located at the `/backup` path when running the server, i.e. `http://localhost:3000/backup`.
In order to utilize it, you need to include your `backupPassword` in the url, like this:  
`http://localhost:3000/backup?pass=password`

This utility allows you to download a `.zip` file of all the ebook and history files on your server and then re-upload those same `.zip` files back to another server. This is helpful if you use a service like Heroku that does not persist your files when you re-upload the core script files.
