Feature request View global option ignore extname

[reggi]

In react-engine you set the view engine via a global app.set variable.

app.set('view engine', 'js')

My request is for another global view option

app.set('view ignore extname', true)

Here's why:

In react engine you pass the current page url to res.render

app.get("/", function(req, res){
  return res.render(req.url, data)
})

When that url has a period it is picked up by a rendering engine the as an extname. So for the url /hello?url=google.com you get an error because it's looking for the module com.

You can enable periods in react-engine simply by commenting out this line. I'm putting in a pull request to copy the whole View with this line commented but it would be great if express supported it.

Is there a way to do this already?

Hi @reggi ! I'm not sure what feature you are requesting. Can you add more details/specificity?

[reggi]

Sorry @dougwilson I pressed enter too quickly and it posted with no content, updated!

[dougwilson]

Unfortunately view names are specifically file system based names. This means you cannot pass in URLs. At best, you can always do res.render(url.parse(req.url).pathname, data) to strip off the query string.

Actually, something we could do is provide something better than a "default" engine, or even expand the default engine in Express 5.0 to include files that have an extension but no mapping.

@dougwilson in the case of react-engine it allows (encourages you) you to pass in req.url. They have methods of rending a specific react view based on the entire url.

Here's a log from this at line [75 of view.js]

Visiting route with this.ext uncommented. (Error Cannot find module 'world')

{ useRouter: true,
  defaultEngine: 'js',
  ext: '.world',
  name: '/hello.world',
  root: '/Users/thomas/Desktop/node-app/public/views' }

Visiting route with this.ext commented. (Works)

{ useRouter: true,
  defaultEngine: 'js',
  name: '/hello.world',
  root: '/Users/thomas/Desktop/node-app/public/views',
  ext: '.js' }

Yes, they can recommend stuff all they want, but it doesn't change the fact that our current views only work with file system names. Frankly, their documentation is wrong/incomplete. You need to use res.render(url.parse(req.url).pathname, data) to strip off the query string.

@dougwilson The example above is the url /hello.world this error would occur with the period in any part of the url even /index.html, so it's not specific to periods in the query string.

@dougwilson The example above is the url /hello.world this error would occur with the period in any part of the url even /index.html.

I've already provided the solution we will implement at #2708 (comment) which would work for the use-case you presented here.
