Selector Safari

Production Build License: MIT Contributor Covenant


Selector Safari is a WIP game for learning CSS selectors!

Selector Safari is made by Drew, Nandana, Kevin, Janis, Nhi, and Lisha from the Teach LA Dev team.

This project is the brainchild of Matt and is inspired by Flexbox Froggy, Grid Garden, and Flexbox Defense. It uses React. We promise it will be playable soon :)


Development Setup

We'll use a really common Node.js project workflow!

First, let's clone our repository, and install all of our node dependencies:

git clone
cd selector-safari
npm install

To start our app, you just need to run npm start!

npm start

And to build our project for production (with CRA's webpack bundling and all that goodness),

npm run build

Contribution Workflow

Want to make a change? Great! Here are the steps:

  1. Either make a new branch or a fork of this repository. master is a protected branch, so you cannot push to it.
  2. Follow the instructions in "Development Setup" above. If you're on a fork, replace the URL with the fork's URL; if you're on a different branch, check it out using git checkout.
  3. Make your changes!
  4. Before you push, make sure your app builds with npm run build. If there are any errors, our CI/CD service will reject your build.
  5. Once you're ready, stage and commit your changes!
  6. Make a pull request with your changes, and let someone on the dev team know. Netlify has a neat feature called "Deploy Previews" that give you a link to preview your changes; see the blog post for more info!
  7. If your code passes code review, we'll merge it into master. Congratulations! If you'd like, it's now safe to delete your branch/fork.

Create React App Artifacts

You can delete these if you want!

This project was bootstrapped with Create React App.

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

npm run eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
