Hi @tigernassau ,

For running a Kemal project on another port different to 3000, you have three alternatives (or even more):

1. You can compile the app by executing the command crystal build src/<name_of_your_app>.cr [options], execute the command ./<name_of_your_app> --port <port_number> and your app will run in the specified port if it is available.
2. You can override the default port number used by Kemal. All you have to do is write Kemal.config.port = <port_number> somewhere in your app. That way you can run the app using the crystal executable like this: crystal src/<name_of_your_app>.cr, and again, your app will run in the specified port if it is available.
3. You can change the default configuration used by Kemal to run the server in development mode. To do that you have to go to libs/kemal/kemal/config.cr and change the instance variable of the class Config at the line 19.

You can change environment with KEMAL_ENV. For example:

KEMAL_ENV=production crystal app.cr

Can you guys add this to the documentation on kemal's website?

@plainas just opened an issue on kemalcr.com repo 👍

@sdogruyol But how does the ECR include stuff works?

So include a view partial from another folder?

@oltmannsdaniel you can use render inside you ecr file.

# /views/main.ecr
<%= render "./views/partial.ecr" %>

Hello from main.
