Soshot make webshot of internet page with headless machine (Google Chrome).


## Ideas

  - If webshot exist in desired size, serve them, if not, verif if complete exist, if exist, crop and resize, save and serve
  - If webshot not exist get information of page and add in the queue
  - Cron job take a webshot of complete page and save them (1920 x complete lenth)
  - Crop image and resize desired format (1920x1080, 1280x720, 160x90 ...), save and serve

SoShot always make complete webshot (1920x page lenght) + first demande size.

Size use 16/9 ratio :

  - fav       = define by config (default 48px)
  - og        = define by the website himself (no resize or crop)
  - thumb     = 160x90
  - nhd       = 640x360
  - hd        = 1280x720
  - full      = 1920x1080
  - complete  = 1920xpage height

## Installation

### Docker (recommended)

For the moment I don't provide any image in any hub.

#### Build image

```shell
wget https://forge.leslibres.org/Knah-Tsaeb/Soshot/raw/branch/main/Dockerfile
docker buildx build --no-cache -t soshot:0.3.0 .
```

#### Start container

You can use native docker volume.

docker run -v soshot_datas:/var/www/datas -v soshot_cache:/var/www/cache -e TZ=UTC -p 8187:80 --name soshot soshot:0.3.0

Or use absolute path

docker run -v /opt/soshot/datas:/var/www/datas -v /opt/soshot/cache:/var/www/public/cache -e TZ=UTC -p 8187:80 --name soshot soshot:0.3.0

### Classic way

#### Requirements

  - PHP 8.*
  - Sqlite3
  - PDO
  - Composer
  - Imagick
  - PHP-GD
  - CRON
  - Chrome / Chromium

Make directory on your web server and go in

```shell
mkdir /var/www/soshot && cd /var/www/soshot
```

Clone git repo

```shell
git clone https://forge.leslibres.org/Knah-Tsaeb/Soshot.git .
```

Install dependencies

```shell
composer install --no-dev
```

Add cron task

```shell
sudo crontab -u www-data -e
```

```shell
php /var/www/soshot/bin/thumbShoter.php
```

Configure your web server to serve in "public" directory.

Go to web page
https://shoshot.your-domain.tld

## Configuration

You can use a web interface (if option "use web gui" is set to true), https://shoshot.your-domain.tld/backend?page=settings

Or you can modify config file /datas/config.json.

```json
{
    "onlyLocalServer": true,
    "webPage": false,
    "log": true,
    "alwaysMakePdf": true,
    "icoSize": 48,
    "expireCache": 12,
    "maxGenPerBatch": 50,
    "permitType": [
        "fav",
        "og",
        "pdf",
        "thumb",
        "nhd",
        "hd",
        "full",
        "complete"
    ],
    "password": "$2y$10$HE5odSvieeVv0cbmK4jau.eg6nqrtpoN0KNPHHaVnPC3vDACAYVAu",
    "key": "acb295c94b12d6364e433d73",
    "chromePath": "chromium",
    "fileFormat": "jpeg"
}
```

| log | bool | true | Not implemented yet |
| alwaysMakePdf | bool | false | If true, SoShot make a complete webshot and PDF of page |
| icoSize | int | 48 | Define size of favicon |
| expireCache | int | 12 | Not implemented yet |
| permitType | array | null | Select authorized size or type of webshot |
| maxGenPerBatch | int | 5 | Foreach cron task as launch, SoShot make 5 webshot |
| key | string | 12 | !!! DANGER !!! If you change key, all previous generation will be invalid. Soshot re make all previous generationt |
| password | string | null | Password for admin interface. No min or max character |
| chromePath | string | null | If path of Chrome/Chromium is not in PATH, you can define here |

## Usage

For generating webshot the entry point is https://shoshot.your-domain.tld/api?

You need to define 3 parameters :

  - type (fav, og, pdf, thumb, hd, full, complete)
  - hmac (hash_hmac('sha1', url of page, your Api key);)
  - url (url of page encode with url_encode)


Example : https://shoshot.your-domain.tld/api?type=fav&hmac=44a2b3f1bc43895c23779f4e71558e9976a4daf2&url=https%3A%2F%2Ffr.wikipedia.org%2Fwiki%2FLogiciel_libre
