I want to use connect-jsonrpc but I can't get my node.js app to run. I
have a fairly simple script:
var connect = require('express');
var math = {
add: function(a, b, fn){
console.log('add');
var result = a + b;
var message = a + " + " + b + " = " + result;
fn(null, result);
},
sub: function(a, b, fn){
fn(null, a - b);
}
};
var date = {
time: function(fn){
fn(null, new Date().toUTCString());
}
};
var port = process.env.PORT || 3000;
connect.createServer(
require('connect-jsonrpc')(math, date)
).listen(port);
console.log('server listening on port ' + port);
The associated package.json is:
{
"name": "node-example",
"version": "0.0.1",
"dependencies": {
"express": "2.2.0",
"connect-jsonrpc": "*"
}
}
When I deploy the app on Heroku I see the following in the logs:
2011-12-15T20:32:07+00:00 heroku[web.1]: State changed from up to
bouncing
2011-12-15T20:32:07+00:00 heroku[web.1]: State changed from bouncing
to created
2011-12-15T20:32:07+00:00 heroku[web.1]: State changed from created to
starting
2011-12-15T20:32:08+00:00 heroku[web.1]: Starting process with command
`node rpc.js`
2011-12-15T20:32:09+00:00 heroku[web.1]: Stopping process with SIGTERM
2011-12-15T20:32:09+00:00 app[web.1]: server listening on port 43825
2011-12-15T20:32:09+00:00 heroku[web.1]: Process exited
The "Process exited" at the end is what concerns me. If I try and test
my service with curl it says "curl: (7) couldn't connect to host".
I have logging set to debug, but I'm not seeing anything insightful. I
suspect it isn't like "connect-rpc" and as such my app isn't starting.
Any help is appreciated.
Thanks
Peter
