  - JSON
  - HTML
  - Text
  - CSV
- Supports [ShareX](https://getsharex.com/) and other screenshot tools

### Demo

See the real world example at [uguu.se](https://uguu.se).

## Requirements

Original development environment is Nginx + PHP5.3 + SQLite, but is confirmed to
work with Apache 2.4 and newer PHP versions like PHP7.3.

Node is used to compile Uguu.

## Install

**Detailed installation and configuration can be found at [Uguu Documentation](https://blog.yeet.nu/blog/uguu-docs).**

If you don't need a detailed one just follow the instructions below.

### Compiling

 First you must get a copy of the uguu code.  To do so, clone this git repo.
 ```bash
 git clone https://github.com/nokonoko/uguu
 ```

 **Run the following commands to do so, please configure `dist.json` before you compile.**
 ```bash
 cd uguu/
 make
 make install
 ```
 OR
 ```bash
 make install DESTDIR=/desired/path/for/site
 ```
 After this, the uguu site is now compressed and set up inside `dist/`, or, if specified, `DESTDIR`.

 ## Configuring

 Front-end related settings, such as the name of the site, and maximum allowable
 file size, are found in `dist.json`.  Changes made here will
 only take effect after rebuilding the site pages.  This may be done by running
 `make` from the root of the site directory.

 **Back-end related settings, such as database configuration, and path for uploaded files, are found in `includes/settings.inc.php`.  Changes made here take effect immediately. Change the following settings:**
 ```php
 define('UGUU_DB_CONN', 'sqlite:/path/to/db/uguu.sq3');
 define('UGUU_FILES_ROOT', '/path/to/file/');
 define('UGUU_URL', 'https://subdomainforyourfiles.your.site');
 ```

 **If you intend to allow uploading files larger than 2 MB, you may also need to
 increase POST size limits in `php.ini` and webserver configuration. For PHP,
 modify `upload_max_filesize` and `post_max_size` values. The configuration
 option for nginx webserver is `client_max_body_size`.**

 **Edit checkdb.sh and checkfiles.sh to the proper paths:**
 ```bash
 sqlite3 /path/to/db/uguu.sq3 "DELETE FROM files WHERE date <= strftime('%s', datetime('now', '-1 day'));"
 ```
 ```bash
 find /path/to/files/ -mmin +1440 -exec rm -f {} \;
 ```
 **Then add them to your crontab:**
 ```bash
 0,30 * * * * bash /path/to/checkfiles.sh
 0,30 * * * * bash /path/to/checkdb.sh
 ```

 These scripts check if DB entries and files are older then 24 hours and if they are deletes them.

 ## MIME/EXT Blocking

 **Blocking certain filetypes from being uploaded can be changed by editing the following settings in `includes/settings.inc.php`:**
 ```php
 define('CONFIG_BLOCKED_EXTENSIONS', serialize(['exe', 'scr', 'com', 'vbs', 'bat', 'cmd', 'htm', 'html', 'jar', 'msi', 'apk', 'phtml', 'svg']));
 define('CONFIG_BLOCKED_MIME', serialize(['application/msword', 'text/html', 'application/x-dosexec', 'application/java', 'application/java-archive', 'application/x-executable', 'application/x-mach-binary', 'image/svg+xml']));
 ```
By default the most common malicious filetypes are blocked.

 ## IP logging
 This is turned off by default, but you can enable it by changing:
 ```php
 define('LOG_IP', 'false');
```

## Anti dupe
This is turned off by default, if a user uploads a file already uploaded the link to the already existing file will be returned instead.
 ```php
 define('ANTI_DUPE', 'false');
```

 ## Using SQLite as DB engine

 We need to create the SQLite database before it may be used by uguu.
 Fortunately, this is incredibly simple.  

 First create a directory for the database, e.g. `mkdir /var/db/uguu`.  
 Then, create a new SQLite database from the schema, e.g. `sqlite3 /var/db/uguu/uguu.sq3 -init /home/uguu/sqlite_schema.sql`.
 Then, finally, ensure the permissions are correct, e.g.
 ```bash
 chown www-data:www-data /var/db/uguu
 chmod 0750 /var/db/uguu
 chmod 0640 /var/db/uguu/uguu.sq3
 ```

 Finally, edit `includes/settings.inc.php` to indicate this is the database engine you would like to use.  Make the changes outlined below
 ```php
 define('UGUU_DB_CONN', '[stuff]'); ---> define('UGUU_DB_CONN', 'sqlite:/var/db/uguu/uguu.sq3');
 define('UGUU_DB_USER', '[stuff]'); ---> define('UGUU_DB_USER', null);
 define('UGUU_DB_PASS', '[stuff]'); ---> define('UGUU_DB_PASS', null);
 ```

 *NOTE: The directory where the SQLite database is stored, must be writable by the web server user*

## API
To upload using curl or make a tool you can post using: 
```
curl -i -F files[]=@yourfile.jpeg https://uguu.se/upload.php (JSON Response)
```
```
curl -i -F files[]=@yourfile.jpeg https://uguu.se/upload.php?output=text (Text Response)
```
```
curl -i -F files[]=@yourfile.jpeg https://uguu.se/upload.php?output=csv (CSV Response)
```
```
curl -i -F files[]=@yourfile.jpeg https://uguu.se/upload.php?output=html (HTML Response)
```
