typescript
The application will receive a POST request with the user's input as a query parameter, parse it, and respond back to Twilio with the weather information. The application uses TypeScript, Express.js, and Twilio Programmable SMS to build a simple web hook that receives text messages and responds with current weather information for a given location.
The application handles environment variables using `env-cmd` to notify the runtime of the environment variables and make them accessible to the application. It also includes error handling using the `withErrorHandling` function to catch any transient errors that may occur when contacting the Weather API or returning the TwiML response.
