Usage

Each web crawler is defined in a yml file

# the name of the crawler
name: Python 3.x docs
# the number of parallel thread workers
threads: 3

# start urls
params:
  start_url: https://docs.python.org/3/index.html

# how/where the results are saved
results:
  type: Json
  file: "python.json"

# on each url labeled "result", results will be extracted using
# this scheme
result_extractor:
  fields:
  - name: title
    rules:
      select: h1
      text: yes
      single: true


# the first page is labeled "start" and for each extracted url, we label it
# accordingly. In this example, we extract the results directly from
# the first page
steps:
- name: start
  label: start
  extract:
  - type: ahrefs
    label: result
    rules:
      select: a.biglink
