express-file-store

express middleware to access/write/remove files (using file path) with various backends.

Usage (middleware)

$ npm install express-file-store --save

var express = require('express');
var FileStore = require('express-file-store');

// using file system
var fileStore = FileStore('fs', {
  path: __dirname + '/public/uploads'
});

// or using gridfs
var fileStore = FileStore('gridfs', {
  url: 'mongodb://localhost:27017/test'
});

// or using s3
var fileStore = FileStore('s3', {
  key: process.env.AMAZON_ACCESS_KEY_ID,
  secret: process.env.AMAZON_ACCESS_KEY_SECRET,
  bucket: 'test',
  region: 'ap-southeast-1'
});

// in express
var app = express();

// POST /a/b/c.png to upload
// GET /a/b/c.png to download
// DELETE /a/b/c.png to remove
app.use(filestore.routes);

// or directly

fileStore.get('/a/b/c.png', function(err, file) {
  console.log(err, file); // null, { filename: '/a/b/c.png', contentType: 'image/png', length: 512, stream: [Readable] }
});

fileStore.put({
  filename: '/a/b/c/d.pdf',
  contentType: 'application/pdf',
  stream: fs.createReadStream('/d.pdf')
}, function(err) {
  console.log(err); // undefined
});

fileStore.remove('../../../../../usr', function(err, file) {
  console.log(err.message); // 'File not found'
});

// ...
