Dance Party

Build Status codecov

Steps to get up and running

git clone git@github.com:code-dot-org/dance-party.git
cd dance-party
nvm install
nvm use
yarn
yarn run dev

At this point the app will be running at localhost:8080. Open the developer tools in Chrome and you can access the API via nativeAPI.*

If you want to make changes locally in dance-party and have them show up in your apps build, do the following:

  • In the code-dot-org/apps directory, run yarn link <path to dance-party>

For example if your dance-party and code-dot-org projects are stored in your root directory, you would run yarn link ~/dance-party. Note that there will be local changes in package.json and yarn.lock that you want to make sure you don't commit.

To debug unit tests in the Chrome debugger: node --inspect --debug-brk ./node_modules/.bin/tape ./test/unit/*.js Open chrome://inspect in Chrome browser (requires Chrome 55+) Tap on inspect link under "Remote Target"

Additional build notes

Node 14.17.1 or higher should be used. This can be achieved by running:

nvm use v14.17.1

It also appears that Python 2.7 should be used and must be available for installing node-gyp. Techniques may vary, but this worked in one situation:

apt-get install python2.7
ln -s /usr/bin/python2.7 /usr/bin/python

Adding New Characters

To add a new character to Dance Party, follow the instructions here: https://github.com/code-dot-org/dance-spritesheets to create the spritesheet for the character.

Effects Testing

yarn run test:visual uses pixelmatch to test for consistency in screenshots between your local branch and an accepted baseline. Accepted baselines are saved in test/visual/fixtures. To debug a test failure, run node ./test/visual/helpers/generateScreenshot.js <effectName> <pathToDirectory> to output the local screenshot to the given directory. If a baseline does not exist for a given effect, the screenshot from your local branch is saved as the baseline. Effects are drawn with no characters on the screen so effects appear the same when drawn as backgrounds or foregrounds.

To Add Test Coverage For a New Effects

Add the name of the effect to the list of effects in backgrounds.js. Run yarn run test:visual. After a new baseline is generated, manually inspect it to ensure it matches expectations.

To Update A Baseline

Delete the accepted baseline. Run yarn run test:visual. After a new baseline is generated, manually inspect it to ensure it matches expectations.

Publishing a new version

First, ensure you have the main branch checked out locally, and that it's up to date.

To publish a new version, the following command should work:

yarn version 1.0.4

With 1.0.4 replaced by the new version number that should be published.

Note: make sure you are logged into npm first. If not, the command may fail with a misleading E404 error. You can see if you're logged in with yarn npm whoami, and if not logged in, can can use yarn npm login.
