Road Sign Manager


Road Sign Manager is a Code4Good at Yale, MakeHaven and New Haven collaborative project to create a cloud platform that can convert and send data to electronic road signs in the city. The project is developed by a team of student developers.

Installation and Usage

  1. git clone the repository.
  2. yarn or npm install.
  3. Rename .env.sample to .env and set the variables accordingly. Note that DATABASE_URL is for the production database; the test and development databases use sqlite and run from memory or a file respectively. You can ignore DATABASE_URL if you don't plan to deploy yet.
  4. yarn dev or npm run dev for development.
  5. If you want to run on the production database, use yarn start or npm start.
  6. yarn test or npm test to run tests.


  1. Deploy
  2. After installing, go to Settings to add parking spaces and road signs.
  3. If you wish to change the password or other config variables, go to the settings page of the heroku instance and edit cofig variables.


At the moment, road-sign-manager is developed by a student team at Code4Good at Yale University. However, feel free to create issues and open pull requests.

  1. git clone the repository if you haven't already.
  2. Make sure you are on the master branch with git status.
  3. git pull to pull the latest updates.
  4. git checkout -b <BRANCH NAME> to checkout a new feature/issue branch. Name the branch after your feature/issue.
  5. Make the changes and test them locally. Remember to install dependencies with yarn else you will get a module not found error. When testing, remember to make a COPY of .env.sample and name it .env before filling out the environment variables.
  6. Before proceeding to submit, run yarn precommit or npm run precommit as well as yarn test/npm run test.
  7. When you are ready to submit, git add . git commit -m "<CHANGES MADE>" git push origin <BRANCH NAME>. DO NOT push to origin master.
  8. Open a pull request on Github and assign @spaceraccoon as the reviewer. In your message, remember to add #<ISSUE NUMBER> so that the request automatically closes the issue when it is merged.
  9. @spaceraccoon will either approve or suggest changes. If the latter, repeat steps 5-6.
You can’t perform that action at this time.
