Laravel File API

Features

• Handle files with Laravel Storage.
• Load files through Laravel routing instead of public path.
• Save images with thumbs, compressed image, and sizes are customisable.

Installation

1. Install File API

   composer require unisharp/laravel-fileapi

2. Set service provider in config/app.php

   Unisharp\FileApi\FileApiServiceProvider::class,

3. publish config file

   php artisan vendor:publish --tag=fileapi_config

Config

in config/fileapi.php

1. fill in the storage path, which make routes for you.

   'path' => ['/images/event/', '/images/article/'],

   it will generate routes like below :

   Route::get('/images/event/{filename}', function ($filename) {
       $entry = new \Unisharp\FileApi\FileApi('/images/event/');
       return $entry->getResponse($filename);
   });
   
   Route::get('/images/article/{filename}', function ($filename) {
       $entry = new \Unisharp\FileApi\FileApi('/images/article/');
       return $entry->getResponse($filename);
   });

2. set default thumb sizes(by key and value)

   'default_thumbs' => ['S' => '96x96', 'M' => '256x256', 'L' => '480x480'],

3. set default image compress quality

   'compress_quality' => 90,

4. choose whether you want to enable upload directly by url(api)

   'enable_api_upload' => false,

   and upload to url by below

   POST /upload/images/event/the-file-name
   

5. and you might also want to set some middlewares to protect the upload route

   'middlewares' => [],

Usage

Initialize File API

use \Unisharp\FileApi\FileApi;
    
$fa = new FileApi(); # use default path (as '/images/')
$fa_event = new FileApi('/images/event/'); # initialize it by giving a base path
$fa_article = new FileApi('/images/article/'); # initiate another instance

Save By Giving Uploaded File

• Default Usage : get unique filename

  $file = $fa->save(\Input::file('main_image')); // => wfj412.jpg

• Custimize your upload file name

  $file = $fa->save(\Input::file('main_image'), 'custom-file-name'); // => custom-file-name.jpg

• By default will set three thumbs(equal scaling)

Thumbnail functions

• Set custom thumb sizes

  $file = $fa
      ->thumbs([
          'S' => '150x100',
          'M' => '300x200',
          'L' => '450x300'
          ])
      ->save(\Input::file('main_image'));

• make cropped thumbs

  $file = $fa->crop()->save(\Input::file('main_image'));

Get image url

// large size
$fa->get('wfj412.jpg');
$fa->get('wfj412.jpg', 'L');
$fa->get('wfj412.jpg', FileApi::SIZE_LARGE);

// medium size
$fa->get('wfj412.jpg', 'M');
$fa->get('wfj412.jpg', FileApi::SIZE_MEDIUM);

// full size
$fa->get('wfj412.jpg', 'full');
$fa->get('wfj412.jpg', FileApi::SIZE_ORIGINAL);

// comporssed
$fa->get('wfj412.jpg', 'CP'); // => get image url of compressed one

Delete image and thumbs

$fa->drop('wfj412.jpg');

Get file fullpath (abstract path from Laravel Storage)

$fa->getPath('wfj412.jpg'); // => '/images/event/wfj412.jpg'

Parse File Path to URL

if you store your file into cloud storage and you want to get url cloud site, you can use url() method to get it

echo $fa->getUrl('wfjsdf.jpg'); // => "https://s3-ap-northeast-1.amazonaws.com/xxx/xxx/55c1e027caa62L.png"

Work with Laravel Storage

• Get file content

  \Storage::get($fa->getPath('wfj412.jpg'));

• Write files

  \Storage::put($fa->getPath('wfj412.jpg'));

• Get Mime Type

  \Storage::mimeType($fa->getPath('wfj412.jpg'));

Auto Upload

if enable_api_upload=true in config/fileapi.php, you can upload file to these two path

1. Image

   • head

        POST /api/v1/images/{target}/{param?}
     

   • body

        image={file multipart body}
     

2. Video

   • head

       /api/v1/videos/{target}/{param?}
     

   • body

       video={file multipar body}
     

After uploaded

you add event listener to finish up after file uploaded, file api will fire image.{target}.created and video.{target}.created

Step

1. Write listener under App\Listeners

    <?php
   
    namespace App\Listeners;
   
    class ArticleImageListener
    {
   
         public function handle($param, $filename, $path)
        {
            ... do something ...
        }
    }
   

2. Write event mapping in Providers\EvnetService\Providers

        protected $listen = [
            'image.article.created' => [
                'App\Listeners\ArticleImageListener'
            ],
        ];
   

Configurations

'enable_api_upload' => false, // auto upload api
'api_prefix' => '/api/v1',    // upload api url prefix
'middlewares' => [],          // middlewares that wrap the api upload route
