A browser-based MMORPG in a fantasy world.

• Node.js 0.10 or higher with npm;
• CoffeeScript;
• Gulp;
• Bower;
• PostgreSQL 9.1 or higher.

uonline expects environment variables DATABASE_URL and DATABASE_URL_TEST to be set. If they are not, it will use following default credentials. You'll probably find it convinient to make the dev environment match them.

• Hostname localhost;
• DB user anonymous with password nopassword;
• Databases: uonline and uonline_test.

• Clone the repo.
• Run script/setup. Please note that it expects database credentials to be set. Also, it will try to create databases if they don't exist.

By the way, running script/update will update the stuff like dependencies and DB revisions. You typically use it after every pull.

Run script/run.

There are also some alternatives:

• foreman start if you want to simulate Heroku environment.
• ./main.coffee for plain run.
• make monitor to automatically restart server on changes.

The following environment variables are recognized:

• IP, PORT — IP and port to listen;
• DATABASE_URL, DATABASE_URL_TEST — database credentials;
• SQLPROF=true — show SQL timings in console;
• NOCSP — don't output CSP header;
• NEW_RELIC_LICENSE_KEY — you don't need this.

This project uses Scripts to Rule Them All for performing routine tasks. All scripts except console are supported.

Run gulp to check and test your code. It will lint your code, run tests, show coverage stats and so on. Please run it before every commit.

Useful subtasks:

• gulp check — only lint;
• gulp build — build static assets;
• gulp watch — same as gulp build, but works automagically.
• gulp test — run unittests without additional checks.

Useful options:

• gulp test --single health-check.coffee — run only one testsuite;
• gulp test --reporter verbose — use other reporter.

• Use tabs, not spaces. Don't mix them and don't use smarttabs.
• Prefer single quotes. Use double quotes when you need to escape ' itself.
• Place use strict in every file.
• Don't omit extension while requiring: require('./utils.js');.
• Sync is better than async. Async is better than callbacks.
• Write tests for everything.
• Write good assert comments: they should answer the question "What do this function should do?".
• Keep things outside of main thread: use asynchronous API. And remember: fs.readFile.sync() is way better than fs.readFileSync().

• Use ? when checking for null or undefined: if error? then ....
• Leave two empty lines between function definitions.
• -> is preferred, () -> is acceptable.
• Use interpolation instead of concatenation.
• Use unless instead of if not. Don't use unless ... else at all.
• Use is instead of == when you don't mean calculations.
• Overall: don't try to make CS look like JS.

• Use if (!!something) when checking for null or undefined.
• Use semicolons even if they're optional.
• Place figure brackets on the same line when you declare an anonymous function and on separate line otherwise.

exports.closeSession = function(dbConnection, sess, callback) {
	if (!sess)
	{
		callback(undefined, 'Not closing: empty sessid');
	}
	else
	{
		dbConnection.query(
			'UPDATE `uniusers` SET `sessexpire` = NOW() WHERE `sessid` = ?',
			[sess], callback);
	}
};

• Use trailing commas. Place them even after last element — it allows you to swap lines easily.
