In this technical guide, Thibaut Barrère shares his method for creating a disk cache plugin for the Elixir Req HTTP client to store HTTP responses on disk and read from the cache for subsequent requests. This approach is particularly useful when working with scripting and data processing tasks that involve repeated HTTP queries, as it reduces the reliance on network calls and speeds up the script execution. The plugin is flexible and integrates into Req's extensible API, allowing for the automatic storage of responses, including the status code and headers, without requiring modifications. Barrère provides a detailed walkthrough of the problem, the core concept of HTTP caching with Req, and his solution which includes registering options, attaching request and response steps to the processing pipeline, and constructing cache filenames based on URLs. He also illustrates how to serialize and deserialize the whole response for efficient caching and retrieval. The article highlights the power of Elixir's programming model for extensibility and the benefits of self-contained scripts enabled by Mix.install/2.
