Requires an Azure Maps subscription key to fetch weather data, which is not included.

In plain English

MinimalWeather is a sample project that shows how to build a simple weather API using different programming approaches. When you send it a location (like a latitude and longitude), it gives you back a combined weather report: current conditions, an hourly forecast for the next 24 hours, and a daily forecast for the next 10 days. Instead of you having to make three separate requests to get all that information, the project handles it in one call. The project works by talking to Microsoft Azure Maps, which provides the underlying weather data. When a request comes in, the code fires off three questions to Azure Maps at the same time: "What's the weather right now?", "What's the hourly forecast?", and "What's the daily forecast?" Once all three answers come back, the code bundles them into a single, tidy response and sends it to you. The repo contains three different versions of the same API, written to compare approaches. One uses a minimalist style in C# that fits in a single short file. Another uses the same language but a more traditional, structured approach with separate files for different responsibilities. A third version is written in TypeScript using Express, a popular JavaScript framework. All three do the exact same thing, just with different tools and code organization styles. This project would be useful for a developer learning how to build APIs in ASP.NET Core or Express, or for someone comparing the two ecosystems. If you are building a weather app and want to see how to combine multiple data sources into one response, this gives you a working blueprint. It also demonstrates a common pattern: making several requests in parallel rather than one at a time, which speeds things up. To use it yourself, you would need a subscription key from Azure Maps, since that is where the weather data actually comes from. The README does not go into detail on setup beyond the code itself.

Copy-paste prompts

Prompt 1
Using the MinimalWeather repo as a reference, write a C# ASP.NET Core minimal API that takes a latitude and longitude, calls three weather endpoints in parallel, and returns a combined JSON response.
Prompt 2
Using the MinimalWeather repo as a reference, write an Express TypeScript API that fetches current conditions, hourly, and daily forecasts from Azure Maps in parallel and returns them as one bundled response.
Prompt 3
Refactor a single-file minimal C# API into a structured multi-file project with separate services for each weather data source, following the MinimalWeather pattern.
Prompt 4
Write a Node Express route that uses Promise.all to fire off three concurrent requests to a weather API and combines the results into one response object.
