|

|
|
<p><code class="docutils literal notranslate"><span class="pre">Funda</span></code> is a real estate housing market that tries to keep track of all houses that are currently for sale.
|
||
|
|
Scraping is not allowed, but on github there are several projects that still try to do this.</p>
|
||
|
|
<p>A quick test from several github projects landed us with <a class="reference external" href="https://github.com/whchien/funda-scraper">this project</a>.</p>
|
||
|
|
<p>This project still works, but is very limited in the filtering methods.
|
||
|
|
A few patches to code allows us to inject a URL that will be used and no other filters will be applied.
|
||
|
|
Next we can setup a basic filter in the browser and copy the URL in order to do scraping.</p>
