Overview

Why does skrape{it} provide its own http client implementations?

Skrape{it} offers an unified, intuitive and DSL-controlled way to make parsing of websites as comfortable as possible.

• Http-Client DSL without verbosity and ceremony to make requests and corresponding request options like headers, cookies etc. in a fluent style interface.

• Pre-configure a client once to either reuse it or adjust only the things that differ at certain requests - especially handy while working with authentication flows or custom headers.

• Can handle client side rendered web pages (e.g. pages created with frameworks like React.js, Angular or Vue.js or pages manipulated with jQuery or other javascript)

A Http request is done as easy as in the given example. Just call the skrape function wherever you want in your code. It will force you to pass a fetcher and makes further request option available in the clojure.

skrape(HttpFetcher) { // <-- pass any Fetcher, e.g. HttpFetcher, BrowserFetcher, ...
    request {
        // ... request options goes here, e.g the most basic would be url
    }
    response {
        // do stuff with the response like parsing the response body ...
    }
}

The http-request is only executed after either the response function has been called. This behaviour also allows to preconfigure the http-client and reusing request settings for multiple calls.
