Stackoverflow Career (Job & Companies) scrapper

Quick n Dirty implementation with scrappy to scrap all jobs and companies on http://careers.stackoverflow.com/jobs

Dependencies

How to run

➜  scrapy-stackoverflows git:(master) ✗ scrapy list
stackoverflowjob
stackoverflowcompany

Import company schema into MySQL:

mysql -u user -p'pass' -H host jobs < company.sql

➜  scrapy-stackoverflows git:(master) ✗ scrapy crawl stackoverflowjob -o test.json -t json

Crawled results are cached in Redis:

redis 127.0.0.1:6379> LRANGE 'stackoverflowcompany:items' 0 11

You can also deploy scrapy as a daemon, see #http://scrapyd.readthedocs.org/en/latest/

TODO

  • Backoff and retry base upon (e.g: http status code)
  • A thin web interface to manipulate jobs (schedule, cancel jobs etc)
  • Add more spiders and crawlers to cover other job boards
  • Deploy it as a real-time API that returns job JSON
  • Basic machine learning with PredictionIO or Mahout
  • Ability to answer basic questions like, what is the top 10 hot jobs in Seattle?
