How to serve a static folder in sails.js?

Question

I want to serve a folder app, which is at the same level with assets folder, under the url /app.

It's possible with AppController to serve file according the url, but I want to know whether it is possible to do this like the following with express?

app.use(express.static(__dirname + '/public'));

Answer 1

In Sails 1.0 you can modify the file config/routes.js and add this:

var express = require('express')
var serveStatic = require('serve-static')
var os = require('os')

const dir = `${os.homedir()}/foo` // dir = /home/dimas/foo

module.exports.routes = {

  '/public/*': serveStatic(dir, {skipAssets: true}), // <-- ADD THIS

  '/': {
    controller: 'FooController',
    action: 'checkLogin'
  },

};

Then you have to create the directory structure:

/home/dimas/foo/public

NOTE that the public entry (the route) is INCLUDED in the filesystem path, the files to be served must be placed there!

After that you can access any content by hitting the following URL:

http://localhost:1337/public/foratemer.txt

You can use custom middleware for express in sails by adding it to your config/http.js:

var express = require('express');
module.exports.express = {
  customMiddleware: function (app) {
      app.use(express.logger());
      app.use(express.compress());
      app.use('/app', express.static(process.cwd() + '/../client/www/'));
    }
};

Off the top of my head, there's two choices:

1. Create a symlink assets/app pointing to your destination. The resources should be accessible via http://your.host.com/app/* since that's the way Sails serves assets.

2. There's still Express underneath Sails, you should be able to access it with sails.express.app and do your thing, let's say, from config/bootstrap.js:

   var express = require('express');

   …

   sails.express.app.use(express.static(process.cwd() + '/app'));
