A single-player basketball simulation game. Make trades, set rosters, draft players, and try to build the next dynasty, all from within your web browser. The game is implemented entirely in client-side JavaScript, backed by IndexedDB.

Basketball GM is NOT open source, but it is also not completely closed. Please see LICENSE.md for details.

If you just want to play the game, go to http://basketball-gm.com/. Instructions below are for developers who want to run a copy locally so they can make changes to the code.

If you want to contribute but get stuck somewhere, please contact me! I'm happy to help.

If you want to contribute code to Basketball GM, you must sign a contributor license agreement. There are separate forms for individuals and entities (such as corporations):

• Individual CLA (this is probably what you want)
• Entity CLA

Make a copy of the form, fill in your information at the bottom, and send an email to commissioner@basketball-gm.com with the subject line, "Contributor License Agreement from YOUR_NAME_HERE (GITHUB_USERNAME_HERE)".

All of the tooling used in development can be installed by simply installing npm and running

npm install

from within this folder.

Basketball GM uses the Browserify for JS minification and clean-css for CSS minification. To minify everything, run

npm run build

However during development, you probably would rather do

npm run watch-js

which will constantly look for changes in your JS files and recompile. Then for CSS files, if you go to Tools > Debug Mode (inside the game), it will use the raw uncompiled CSS files so you don't need to keep compiling them after each change. Debug Mode also creates a global variable window.bbgm which gives you access to many of the internal functions of Basketball GM.

To run the game locally, you need some way of running a web server to display the content. There are currently three ways to do it. It doesn't matter which you use as long as you can get it to run on your computer.

Run the included mongoose-tiny-4.1.exe and point your browser to http://localhost:8080/.

That's it.

If that doesn't work, try right clicking on the Mongoose icon in your notification area and poke around in there. You can also see if there is a newer version of Mongoose available http://cesanta.com/downloads.html.

Run

npm start

and point your browser to http://localhost:3000/.

The mod_rewrite rules in .htaccess can be used to make Apache run Basketball GM. Everything should work if you just have a domain/subdomain point at this folder with mod_rewrite enabled. That's how it's done on basketball-gm.com.

ESLint is used to enforce some coding standards. It's mostly pretty standard Crockfordian stuff. To run ESLint on the entire codebase, run

npm run lint

Integration and unit tests are bunched together in the js/test folder. Coverage is not great. They can be run from the command line in Karma with

npm test

or manually within a web browser by running npm run build-test (or npm run watch-test) and going to http://localhost:8080/test.

Basketball GM is a single-page app that runs almost entirely client-side by storing data in IndexedDB. All the application code is in the js folder. Routes are set in js/app.js. Most of the important stuff is in js/core.

UI is ultimately driven by js/util/bbgmView.js, a small UI layer I wrote on top of Knockout which is used by all the views in the js/views folder. Each view also has a corresponding HTML file in the templates folder. Adding a new page is kind of a bitch. You need to explicitly include the template file in js/templates.js, and explicitly include the view in js/views.js. Beyond that, my best guidance is to copy from an existing page and use that as a starting point.

For database access, I wrote a very thin Promises-based wrapper around IndexedDB which can be found in js/dao.js. Understanding how IndexedDB works is critical in any non-trivial work on Basketball GM.

Code should ideally be documented as described in the Google Closure Compiler documentation: https://developers.google.com/closure/compiler/docs/js-for-compiler. Google Closure Compiler itself isn't actually used for anything (yet).

If you want to contribute changes back to the project, first create a fork on GitHub. Then make your changes in a new branch. Confirm that the tests (hopefully including new ones you wrote!) and ESLint all pass. Finally, send me a pull request.

It's also probably a good idea to create an issue on GitHub before you start working on something to keep me in the loop.

Basketball GM's layout is currently based on Bootstrap 3.1.1 with the following options:

• @font-size-base set to 13px

Abbreviations of stats should be done like basketball-reference.com stat pages. For instance, "defensive rebounds" is "drb".

• Make sure tests all pass (if necessary)

• Write database upgrade code in db.js (if not already done piecemeal)

• Write key changes in js/data/changes.js

• Set version in index.html, CHANGES.md, and README.md, like http://semver.org/

• Tag it in git like:

    git tag -a v3.0.0-beta.2 -m ''
    git push --tags
  

The game runs equally well within a web browser and within Cordova (Android 4.4+). The codebase is designed to handle both situations (the main difference is absolute vs relative paths, governed by window.inCordova in index.html). To collect the files needed for Cordova, run npm run build-cordova and look in the cordova folder.

Warning: This hasn't been tested in a while and is probably broken by now.
