Using custom express middleware in Sails.js circa v0.9.3

custom-express-middleware.md

Custom middleware is a legacy option, since most times you just want to use policies.

HOWEVER! There are times you want to use sails for quick/dirty things you would normally use express for (but you already have sails around, w/e). More pertinently, if you want middleware to run before the static files from your assets folder are served, policies won't let you do that.

Here's an example of using the BasicAuth middleware for everything:

// Put this in `config/express.js`
module.exports.express = {
  customMiddleware: function (app) {
    app.use(require('../node_modules/sails/node_modules/express').basicAuth('balderdash', 'wickywocky'));
  }
};

Keep in mind this technique only works with Express (and your static files are only available that way anyhow)

Hi Mike,

For some reason, my customMiddleware function is not firing. I have the code in the right file (config/express.js). Any ideas? Here's the code -

var passport = require('passport');

module.exports.express = {
customMiddleware: function (app) {
console.log('INITIALIZE');
app.use(passport.initialize());
app.use(passport.session());
}
};

Thanks,

_K

Scratch that Mike. I didn't have express installed. Now, I get past this issue and stuck at the passport Verify handler for Google Oauth never being called issue. The search continues :)

@kkotak @mikermcneil I wonder as _K did by putting passport.initialize on a new file under config directory.
Is that a preferable and clean way for sails? Should it have any other way to initialize passport in api directory, instead?

For new .10 Sails JS use http.
module.exports = {
http: {
customMiddleware: function(app) {
console.log('Express middleware for passport');
app.use(passport.initialize());
app.use(passport.session());
}
}
};

I'm new to sails and node.js and I don't know if I'm doing it the sails way. I've defined my middleware configuration for passport like this:

// Location: /config/passport.js
var passport    = require('passport'),
  LocalStrategy = require('passport-local').Strategy,
  bcrypt = require('bcrypt');

passport.serializeUser(function(user, done) {
  done(null, user[0].id);
});

passport.deserializeUser(function(id, done) {
  User.findById(id, function (err, user) {
    done(err, user);
  });
});

passport.use(new LocalStrategy(
  function(username, password, done) {
    User.find({username: username}).exec(function(err, user) {
      if (err) { return done(null, err); }
      if (!user || user.length < 1) { return done(null, false, { message: 'Incorrect User'}); }
      bcrypt.compare(password, user[0].password, function(err, res) {
        if (!res) return done(null, false, { message: 'Invalid Password'});
        return done(null, user);
      });
    });
  })
);

module.exports = {
  init: function(app){
    app.use(passport.initialize());
    app.use(passport.session());
  }
}

// Location: /config/express.js
module.exports.express = {
  customMiddleware: function(app){
    require('./passport.js').init(app);
  }
}

It works fine for me but I don't know if it follows proper conventions. Sails version is 0.10.5.

I am sending
type : "POST",
data: "a",
contentType : "application/x-www-form-urlencoded;charset=ISO-8859-15",
dataType : 'json',
ajax request but I am getting
{ "a": ""} in my back-end in sails.
Since I'm new to sails I have problem regarding writing middlewares.
Please help me in configuring "config/http.js" regarding my ajax requests.
Thanks in advance@mikermcneil
