Dew Point Forecast

This is a small web application that provides the dew point for forecast for a selected location. The dew point is the temperature at which dew forms as air is cooled. Knowing the dewpoint is good for determining how humid a day will feel.

Building

This application is built with Rust using the Rocket web framework. It also makes use of the IP2Location DB for mapping IPs to countries. The database is available from https://lite.ip2location.com/database/db1-ip-country and should be placed in the root of the project.

Configuration

There is a sample config file in Rocket.toml.sample, copy this to Rocket.toml and add the two keys. For the OpenWeather API key you will need to create an account at https://openweathermap.org/.

Configuration can also be done via environment variables, which is handy for prod deployment. See the Rocket documentation for details.

Build

cargo build

The binary will be in target/debug/dewpoint.

Production Build

Add --release to the build command:

cargo build --release

The binary will be in target/release/dewpoint.

Run

cargo run

Tips

Fast auto-rebuilding server:

watchexec -w src -w templates -s SIGINT -r 'mold -run cargo run'

Note:

• watchexec watches the file-system and runs a command when changes are detected
• mold is a fast linker for Linux.
