This project utilizes the fantastic:

Open-Meteo weather forecast API

Nominatim open-source geocoding service which uses OpenStreetMap data.

A big thanks to their teams for providing these valuable resources!

This project implements a GraphQL gateway in Elixir using Phoenix and Absinthe. It seamlessly integrates the Open-Meteo weather API and Nominatim geocoding service as data sources, providing a structured GraphQL interface.

Leverages Elixir's concurrency and fault tolerance for a robust and scalable solution.

Employs Phoenix for efficient web server handling and interaction.

Utilizes Absinthe for defining and managing the GraphQL schema and resolvers.

Offers dedicated contexts for interacting with each API:

Both contexts utilize HTTP clients for communication with their respective APIs.

GraphqlAdapter and GraphqlSerializer components within each context bridge the gap between GraphQL and the APIs (data fetching and serialization).
