Add HTTP API for your `Scrapy <https://scrapy.org/>`_ project in minutes.

You send a request to ScrapyRT with spider name and URL, and in response, you get items collected by a spider
visiting this URL. 

* All Scrapy project components (e.g. middleware, pipelines, extensions) are supported
* You run Scrapyrt in Scrapy project directory. It starts HTTP server allowing you to schedule spiders and get spider output in JSON.


Quickstart
===============

**1. install**

.. code-block:: shell

    > pip install scrapyrt

**2. switch to Scrapy project (e.g. quotesbot project)**

.. code-block:: shell

    > cd my/project_path/is/quotesbot

**3. launch ScrapyRT**

.. code-block:: shell

    > scrapyrt

**4. run your spiders**

.. code-block:: shell

    > curl "localhost:9080/crawl.json?spider_name=toscrape-css&url=http://quotes.toscrape.com/"

**5. run more complex query, e.g. specify callback for Scrapy request and zipcode argument for spider**

.. code-block:: shell

    >  curl --data '{"request": {"url": "http://quotes.toscrape.com/page/2/", "callback":"some_callback"}, "spider_name": "toscrape-css", "crawl_args": {"zipcode":"14000"}}' http://localhost:9080/crawl.json -v

Scrapyrt will look for ``scrapy.cfg`` file to determine your project settings,
and will raise error if it won't find one.  Note that you need to have all
your project requirements installed.

Note
====
* Project is not a replacement for `Scrapyd <https://scrapyd.readthedocs.io/en/stable/>`_ or `Scrapy Cloud <https://www.zyte.com/scrapy-cloud/>`_ or other infrastructure to run long running crawls
* Not suitable for long running spiders, good for spiders that will fetch one response from some website and return items quickly
