Weather Forecast Application
A weather forecast application that allows users to search a city’s weather and save their favorite cities. The application performs API calls to a third party resource to fetch for weather data. The backend is built with Flask and the frontend is built with JavaScript, Bootstrap, HTML, and CSS.
Live site
https://weather-app100.herokuapp.com/
Main Features
- Usage of Flask Template to built User Registration, Login/Logout, and Account Views.
- Save and delete cities functionality built with CRUD operation.
- Usage of Flask-SQLAlchemy to built Database to store user information
- Implemented AJAX calls with jQuery to allow users to request for a different city weather without having to reload the page.
- Usage of Flask-Bcrypt for User Authentication and storage of Password
- Usage of request library to fetch third party’s data through its API
- Package Structure and Configuration for deployment in Heroku
Features in development
- Ability to modify cities in dashboard
- Ability to use Google map to select location
Challenges
- First time adding AJAX to a flask application. This stack is uncommon, hence it was more difficult to find useful documentations.
- Some libraries mentioned in the tutorial were deprecated. I had to find solutions to replace the deprecated methods.
- First time deploying on Heroku, hence running into many unfamiliar challenges specifically related to deployment.
Others
Third Party API limitation
OpenWeatherMap API only support up to 60 calls within an hour. If you see an error in the website, this could mean that you have reached the limitation of API calls.
Heroku limitation
Heroku’s free tier hosting server will sleep the server after 30 minutes of
inactivity, hence the website could take a couple minute to load up.
