Elixir HTTP Client

Introduction to Elixir HTTP Clients

Elixir provides robust libraries for making HTTP requests, with HTTPoison and Req being the most popular. These libraries allow developers to interact with external APIs seamlessly. In this guide, we'll explore how to use both HTTPoison and Req for making HTTP requests.

Using HTTPoison for HTTP Requests

HTTPoison is a popular choice for making HTTP requests in Elixir. It is built on top of Hackney, providing a simple and intuitive API. To get started, you'll need to add HTTPoison to your project dependencies.

Once HTTPoison is installed, you can make a simple GET request to fetch data from an API. Here's how to perform a basic GET request:

Using Req for HTTP Requests

Req is another powerful HTTP client library for Elixir, known for its simplicity and ease of use. To use Req, add it to your project dependencies:

With Req installed, you can perform HTTP requests with a concise syntax. Here's an example of making a GET request:

Choosing Between HTTPoison and Req

Both HTTPoison and Req offer unique features that may suit different project needs. HTTPoison is well-suited for projects that require more control over HTTP requests and responses, while Req is ideal for developers seeking a more straightforward and minimal interface.

• HTTPoison: Offers more control and is built on Hackney.
• Req: Provides simplicity and ease of use.

Consider your project's specific requirements when choosing the right library.
