This project frontend is made with Angular and that is already included in the dist directory. If you want to change the frontend you can find the repo here.
You can find the live version hosted in heroku here
Run npm install to install all the dependencies.
Make sure you have an instance of Postgres running and create the environmental variables or an .env file with the names inside the .env.example file.
Once Postgres and the variables are set up, run the database migrations with npx sequelize-cli db:migrate. If you need to undo a migration you can run npx sequelize-cli db:migrate:undo.
For more information about Sequelize migrations see here.
Run npm run dev for a dev server. Navigate to http://localhost:4000/ (or the port you specified in the variable PORT).
Run npm start for the production server.
NOTE: Right now the src/app.js and the src/server.js include as origin my heroku application, so make sure you change it or otherwise the application won't run properly.
