SendAsyncHttpR

SendAsyncHttpR is a lightweight, asynchronous HTTP client library designed for use within the R programming environment. It is built on top of the popular **httpuv** package, leveraging the **libuv** event loop for efficient non-blocking network operations. The library is particularly useful for applications requiring concurrent HTTP requests, such as web scraping, API interactions, or data retrieval from multiple endpoints simultaneously.

One of the key features of SendAsyncHttpR is its ability to execute HTTP requests asynchronously, allowing R scripts to perform other tasks while waiting for responses. This is achieved through the use of futures and promises, which enable parallel processing without overloading the system’s resources. The library supports standard HTTP methods, including GET, POST, PUT, DELETE, and PATCH, along with custom headers, query parameters, and request bodies.

SendAsyncHttpR is particularly well-suited for scenarios where traditional synchronous HTTP calls would introduce delays or bottlenecks. For example, when fetching data from multiple APIs, the library can queue requests and process them asynchronously, significantly improving performance. It also includes built-in error handling to manage issues such as timeouts, connection failures, or invalid responses.

The package is maintained as an open-source project, with contributions from the R community. While it is not as feature-rich as some commercial alternatives, its simplicity and efficiency make it a practical choice for developers working with asynchronous HTTP operations in R. Documentation and examples are available through the package’s CRAN page, providing guidance on installation, usage, and troubleshooting common issues.
