Change Express view folder based on where is the file that res.render() is called

Question

I would like to change the view folder of Express when I call res.render().

For example, if I call res.render(viewName) inside /folder/file.js, I would like that Express look for the view inside /folder/views.

If the file is inside /folder1/folder2/file.js, I would like that Express look for the view inside /folder1/folder2/views

Is it possible ?

You can use the method set() to redefine express's default settings.

app.set('views', path.join(__dirname, '/yourViewDirectory')); 

• Express documentation

For a dynamic path change you can do something like this:

var express = require('express'); var path = require('path'); var app = express();  app.engine('jade', require('jade').__express); app.set('view engine','jade');  app.customRender = function (root,name,fn) {      var engines = app.engines;     var cache = app.cache;      view = cache[root+'-'+name];      if (!view) {         view = new (app.get('view'))(name, {           defaultEngine: app.get('view engine'),           root: root,           engines: engines         });          if (!view.path) {           var err = new Error('Failed to lookup view "' + name + '" in views directory "' + root + '"');           err.view = view;           return fn(err);         }          cache[root+'-'+name] = view;     }      try {       view.render(opts, fn);     } catch (err) {       fn(err);     } }  app.get('/', function(req, res) {      app.customRender(path.join(__dirname, '/path/to/user/'),'index',function (err,html) {         if (err)             res.send(404);         else             res.send(200,html);     });  });  app.listen(3000);
