Alleup

Flexible way to resize and upload images to Amazon S3 or file system storages for Node.js. Possible to add different versions of the same file in cropped or resized variant.

Installation

$ npm install alleup

Quick Start

  1. You need to create alleup configuration file with image variants and your storages Example:

    {
        "variants": {
            "resize": {
                "mini" : "300x200",
                "preview": "800x600"
            },
            "crop": {
                "thumb": "200x200"
            }
        },
    
        "storage": {
            "aws": {
                "key" : "AWS_KEY",
                "secret" : "AWS_SECRET",
                "bucket" : "AWS_BUCKET"
            },
            "dir": {
                "path" : "./public/images/" 
            }
        }
    }
    Example config with scopes (only from version 0.1.0):
    
    {
        "variants": {
            "projects": { //projects is scope
              "resize": {
                  "mini" : "300x200",
                  "preview": "800x600"
              },
              "crop": {
                 "thumb": "200x200"
              }
            },
    
            "gallery": { //gallery is scope
               "crop": {
                "thumb": "100x100"
               }    
            }
        },
    
        "storage": {
            "aws": {
                "key" : "AWS_KEY",
                "secret" : "AWS_SECRET",
                "bucket" : "AWS_BUCKET"
            },
            "dir": {
                "path" : "./public/images/" 
            }
        }
    }
    
  1. Now you can use Alleup

    var  Alleup = require('alleup');
    var alleup = new Alleup({storage : "aws", config_file: "path_to_alleup_config.json"})
    
    You can use `storage: 'aws'` for store files on Amazon S3 or `storage: 'dir'` for store files in filesystem
    

UPLOAD, URL and DELETE

  1. Upload example:

    app.get('/upload_form', function(req, res) {
      res.writeHead(200, {'content-type': 'text/html'});
        res.end(
          '<form action="/upload" enctype="multipart/form-data" method="post">'+
            '<input type="text" name="title"><br>'+
            '<input type="file" name="upload" multiple="multiple"><br>'+
            '<input type="submit" value="Upload">'+
          '</form>'
        );
    
    });
    
    app.post('/upload',  function(req, res) {
     // Without Scopes
      alleup.upload(req, res, function(err, file, res){
    
          console.log("FILE UPLOADED: " + file);
          // THIS YOU CAN SAVE FILE TO DATABASE FOR EXAMPLE
          res.end();
      });
    
     //With Scope `projects` (look at example of configuration file)
     alleup.upload(req, res, function(err, file, res){
    
         console.log("FILE UPLOADED: " + file);
         // THIS YOU CAN SAVE FILE TO DATABASE FOR EXAMPLE
         res.end();
     }, 'projects');
    
    });
    
  1. Remove uploaded file example:

    // Without Scopes
    app.get('/delete',  function(req, res) {
      alleup.remove('1322506647.jpg', function(err) {
    
          // THIS YOU CAN DELETE FILE FROM DATABASE FOR EXAMPLE
          res.end();
      });
    
    // With Scope `projects` (look at example of configuration file)
    app.get('/delete',  function(req, res) {
      alleup.remove('1322506647.jpg', function(err) {
    
          // THIS YOU CAN DELETE FILE FROM DATABASE FOR EXAMPLE
          res.end();
      }, 'projects'); 
    });
    
  1. Get file url example:

    alleup.url(file, variant);
    

file - The name of the file you uploaded, saved for example in database (345621345.jpg), variant - one of your image variants names from alleup_congig.json
