title: Parse S3FileAdapter
body: <p>I currently have a parse-server deployment working however every time I upload a file it stores it with the <code>GridStore</code> file adapter instead of the S3 one. My app JS looks like this:</p>
  
  <pre><code>// Example express application adding the parse-server module to expose Parse
  // compatible API routes.
  
  var express = require('express');
  var ParseServer = require('parse-server').ParseServer;
  var path = require('path');
  
  var S3Adapter = require('parse-server').S3Adapter;
  
  var databaseUri = process.env.DATABASE_URI || process.env.MONGOLAB_URI;
  
  if (!databaseUri) {
    console.log('DATABASE_URI not specified, falling back to localhost.');
  }
  
  var api = new ParseServer({
    databaseURI: databaseUri || 'mongodb://localhost:27017/dev',
    cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',
    appId: process.env.APP_ID || 'somAppId',
    masterKey: process.env.MASTER_KEY || '', //Add your master key here. Keep it secret!
    serverURL: process.env.SERVER_URL || 'http://localhost:1337/parse',  // Don't forget to change to https if needed
    liveQuery: {
      classNames: ["Posts", "Comments"] // List of classes to support for query subscriptions
    },
    filesAdapter: new S3Adapter(
      "S31",
      "S32",
      "bucket-name",
      {directAccess: true}
    )
  });
  // Client-keys like the javascript key or the .NET key are not necessary with parse-server
  // If you wish you require them, you can set them as options in the initialization above:
  // javascriptKey, restAPIKey, dotNetKey, clientKey
  
  var app = express();
  
  // Serve static assets from the /public folder
  app.use('/public', express.static(path.join(__dirname, '/public')));
  
  // Serve the Parse API on the /parse URL prefix
  var mountPath = process.env.PARSE_MOUNT || '/parse';
  app.use(mountPath, api);
  
  // Parse Server plays nicely with the rest of your web routes
  app.get('/', function(req, res) {
    res.status(200).send('Make sure to star the parse-server repo on GitHub!');
  });
  
  // There will be a test page available on the /test path of your server url
  // Remove this before launching your app
  app.get('/test', function(req, res) {
    res.sendFile(path.join(__dirname, '/public/test.html'));
  });
  
  var port = process.env.PORT || 1337;
  var httpServer = require('http').createServer(app);
  httpServer.listen(port, function() {
      console.log('parse-server-example running on port ' + port + '.');
  });
  
  // This will enable the Live Query real-time server
  ParseServer.createLiveQueryServer(httpServer);
  </code></pre>
  
  <p>After I deploy I do not get any errors. Everything seems to be running fine. However, when I upload a file it goes to my monglab DB instead of my S3 storage. Do I need to do something else to configure this? I'm using the docs as a reference to configure this:</p>

  <p>I also noticed that on the parse-server repo it does not have an S3FileAdapter:

  <p>Any help will be greatly appreciated!</p>
  
  <p>Thanks,</p>
