Source: https://github.com/mischov/reaver/blob/master/README.md

This snippet shows how to add Reaver as a project dependency in a Clojure application. The provided line should be added to the `project.clj` file under the `:dependencies` vector, allowing the project to use Reaver's functionalities.

### Extracting Headlines and Links from HTML using Reaver

Source: https://github.com/mischov/reaver/blob/master/README.md

This snippet demonstrates how to use Reaver to parse an HTML string and extract specific data, such as headlines and URLs, into a sequence of Clojure maps. It requires an HTML string as input, which can be fetched using `slurp` or other HTTP clients. The `parse` function converts the HTML into a traversable structure, and `extract-from` uses CSS selectors to pull out desired elements and their attributes or text content.

```Clojure
(require '[reaver :refer [parse extract-from text attr]])

; Reaver doesn't tell you how fetch your HTML. Use `slurp` or
; aleph or clj-http or what-have-you.
(def hacker-news (slurp "https://news.ycombinator.com/"))

; Extract the headlines and urls from the HTML into a seq of maps.
(extract-from (parse hacker-news) ".itemlist .athing"
              [:headline :url]
              ".title > a" text
              ".title > a" (attr :href))

;> ({:headline "...", :url "..."}, {:headline "...", :url "..."}, ...)
```
