amber on cloud9
Locked
 
|
I have used amber on cloud9 before (https://c9.io/). However due to changes in the code, it doesn't seem to work anymore.
The only thing I need to be able to do is to specify a port and ip through javascript in nodejs, which are: "process.env.PORT" and "process.env.IP" instead of 4000 and 127.0.0.1 Before the changes, I used to edit server.js and just replace 4000 with "process.env.PORT", but this does not seem to be working anymore. Do I need to use amberc or something? Ideally there's a way to do this without a script change, but I'm not sure if I can get the port necessary outside of javascript. -Jacob

Hi Jacob, the Server and REPL have been merged into the AmberCli package which can be found in the cli directory. The ./bin/server script uses this package to retain old behavior but will be removed in the future.
You should be able to edit the file cli/js/amber-cli.js and replace the return values of defaultPort and defaultHost to get the desired behavior. AmberC is the comandline compiler for Amber and is not related to the server executable.

Hi Jacob,
use: $ node_modules/amber/bin/server --host $IP --port $PORT and then access the server with the "http://projectname.username.c9.io" URL scheme max On Friday, June 14, 2013 2:29:32 PM UTC+2, Zenchess wrote: I have used amber on cloud9 before (https://c9.io/).

Not .../bin/server --options (deprecated), but .../bin/amber serve --options (supported).

Mea culpa.
Pity the change did not slip into 0.11.0.

since we're trying to release more often, hopefully we won't have to wait too long :)

I just thought I'd test the latest Amber 0.12.1 on Cloud9 and I wonder if anyone could point to what I am doing wrong.

Hi Geert, this looks like an error on NPM side. I remember seeing something like this a few weeks ago on the Amber Travis. Unfortunately I can't find the link right now.
The warning about 'st' and 'js' directories is not necessarily an issue if you don't want to commit code back to the server. To get more information you could try to check the JavaScript console when loading the index.html file.

I am not too fussed about the warnings because I think had those with previous versions of Amber too.
With a previous version of Amber I was at least able to get to the Amber IDE via http://projectname.username.c9.io instead of the "500 Internal server error" I get now. |

IIRC one of the reasons why amber server gives 500 is when you load root of the site and index.html is missing (I wonder why it is not 404 or 403 at least).
Your example look like that.

Hi Geert, I just tried creating an Amber application on Cloud9 myself and didn't face any issues. Here are the steps I performed: 1. create a new Node.js workspace
2. remove all template files 3. 'npm install -g bower' 4. 'bower init' (this can probably be left out) 5. 'bower install amber --save' 6. create index.html with contents taken from https://github.com/amber-smalltalk/amber/blob/master/index.html
7. prepend paths for amber.js and require.js with 'bower_components/amber/' 8. './bower_components/amber/bin/amber serve --host $IP --port $PORT' 9. point browser to http://<your workspacename>.<your username>.c9.io
Afterwards, the browser loaded the Amber IDE. As indicated by Herby you are missing an index.html file in the directory from where you execute ./bin/amber serve. This is also printed in the console warning.
However, return 500 is probably not the best thing to do :-) I'll take a look and add a better error handling. Note that you can use --base-path to specify where your index.html is located or --fallback-page which tells the server which page to use if it can't find a specific resource.
Best, Manfred PS: it is really hard to separate the console output from what you actually wrote. It would be great if you could separate this a bit better the next time you have such an error.

For those who are interested in the topic, I added the changes to the following pull request:
It replaces the 500 error with a 404 answer and the response now contains a (hopefully) better description. Best, Manfred On Sun, Nov 24, 2013 at 1:43 PM, Manfred Kröhnert <[hidden email]> wrote:
