How we built it

  • For the app, we used React-Native and Expo, Google Maps API to show map.
  • We used Infobip to exchange SMS messages with the user.
  • Using Google Cloud's Vertex AI, we classified requests and generated responses.
  • Our weather, washroom, and campground data are all from the Government of Canada.
  • The MySQL database is hosted on GCP using CloudSQL.
  • GitHub actions automatically test our APIs using Postman's Newman. Actions also automatically containerize and build our app in Google Cloud using Cloud Run.

Challenges we ran into

  • Displaying routes using the Google Maps API was quite difficult. We ended up using GeoJSON to map coordinates in GoogleMaps and the Polyline component to display the route.
  • We had issues importing data into MySQL
  • Creating GitHub actions and modifying them (if it wasn't obvious from the commits)

Accomplishments that we're proud of

  • We were able to automate deployment and testing using GitHub actions
  • It's our first time using MySQL
  • We are able to send and receive SMS using Infobip

Building a React-Native app for the first time!!! It was really fun learning about how to use components in React-Native and make a development build through Expo.

What we learned

  • How to use Infobip
  • How to use GitHub actions
  • SQL syntax
  • Managing applications in GCP

What's next for TrailGuide

Implementing an algorithm to find the optimal hiking route between two locations and show potential alternative routes.
