What to do when documentation have change the way you use to get things done?

Yes, it is tricky. Documentation and tutorials can quickly go out-of-date, especially with NodeJS and Express who have major releases more often. Most software will publish change logs and possibly migration guides to help users adapt to new methodologies.

What I do is get familiar with what has changed that way I can spot what I need to modify mentally when progressing through tutorials.

Ok. I'm trying to be updated according to the method I am having doubts on the link to the other question in the link. Thanks.

You can't. I think any tutorials on something as bleeding edge as node are actually counterproductive, because they are overly specific.

Well my problem was while typing res.render("index.exo") instead of res.send("Hello world")

I've being asking in other forums but they gave me answers that will display the index.eco file but it won't be using the render method that also is important for me because the project I am working on, needs to be done with that or similar. But as I am new to node.js it's quite hard to chose another way like the example they gave me in the forum.

I've just recieved this answer:

express = require("express")
app = express()
cons = require("consolidate")

 app.engine "eco", cons.eco
     app.get "/", (req, res) ->
     res.render __dirname + "/template.eco", layout: false

They told me that eco is now supported by requiring "consolidate". Is this the new way to get this done?

Thanks Chris. I'll keep going as you told me to.

Hey Rodrigo Muñoz did you complete the Code Racer Project. I am so disappointed that the source code is not available and Everything changed so much.
