HTTPoison
Yet Another HTTP client for Elixir powered by hackney
HTTP client for Elixir, based on HTTPotion. HTTPoison uses hackney to execute HTTP requests instead of ibrowse. Using hackney we work only with binaries instead of string lists. First, add HTTPoison to your mix.exs dependencies. Add :httpoison to your applications list if your Elixir version is 1.3 or lower. You can also easily pattern match on the HTTPoison.Response struct. There are a number of supported options(not to be confused with the HTTP options method), documented here, that can be added to your request. The example below shows the use of the :ssl and :recv_timeout options for a post request to an api that requires a bearer token. The :ssl option allows you to set options accepted by the Erlang SSL module, and :recv_timeout sets a timeout on receiving a response, the default is 5000ms. -

Elixir Code Smells
Catalog of Elixir-specific code smells
Elixir-Code-Smells is a research-driven catalog of code smells specific to the Elixir programming language. Unlike generic code smell lists, this project identifies issues emerging from Elixir’s functional, concurrent, and process-based nature. Initially compiled via grey literature (blogs, talks, forums), the catalog now includes 23 Elixir-specific smells plus 12 traditional smells adapted to Elixir. Each entry documents the name, category, problem, example, refactoring strategy, and step-by-step treatments. The smells are grouped into two categories: design-related (coarse-grained, harder to detect, affecting architecture/processes) and low-level concerns (fine-grained, often readability and maintainability issues). The catalog evolves with community feedback and contributions, aiming to help developers recognize harmful patterns and apply disciplined refactoring to improve maintainability, testability, and performance in Elixir systems. -

Elixir
Dynamic, functional language designed for building scalable apps
Elixir is a dynamic, functional language for building scalable and maintainable applications. Elixir leverages the Erlang VM, known for running low-latency, distributed, and fault-tolerant systems. Elixir is successfully used in web development, embedded software, data ingestion, and multimedia processing, across a wide range of industries. All Elixir code runs inside lightweight threads of execution (called processes) that are isolated and exchange information via messages. Due to their lightweight nature, it is not uncommon to have hundreds of thousands of processes running concurrently in the same machine. Isolation allows processes to be garbage collected independently, reducing system-wide pauses, and using all machine resources as efficiently as possible (vertical scaling). Processes are also able to communicate with other processes running on different machines in the same network. -

Jason
A blazing fast JSON parser and generator in pure Elixir
A blazing-fast JSON parser and generator in pure Elixir. The parser and generator are at least twice as fast as other Elixir/Erlang libraries (most notably Poison). The performance is comparable to jiffy, which is implemented in C as a NIF. Jason is usually only twice as slow. Both the parser and generator fully conform to RFC 8259 and ECMA 404 standards. The parser is tested using JSONTestSuite. The package can be installed by adding jason to your list of dependencies in mix.exs. Jason follows the JSON spec more strictly, for example, it does not allow unescaped newline characters in JSON strings - e.g. "\"\n\"" will produce a decoding error. No support for decoding into data structures (the as: option). No built-in encoders for MapSet, Range and Stream. No support for encoding arbitrary structs - explicit implementation of the Jason.Encoder protocol is always required. Different pretty-printing customization options (default pretty: true works the same). -
