Welcome to databot’s world!¶
The databot applicaton is made with one or many pipes and run by
The simplest applicaton looks like:
Concept of the databot is very simple.
`I doubt if it is good to write a guide :-)`
Pipe works at the Top level. It combines the Node and Route together.
Node is callable: in python world, we have three callable things:
- function object. Class with
Route is for duplicating data for multiple purposes. for simple applicaiton, you don’t need route. Just a main pipe.
- case 1: when get a tick bitcoin price from api,
- you want save it to file and mysql at same time.
Pipe( get_price, Branch(save_to_db), save_to_file ）
case 2: crawler gets a google search result page. It may need to parse search result and next page link .
Pipe( "https://www.google.com/search?q=kkyon+databot", HttpLoader(), Branch(parse_search_result,save_to_db), parse_all_page_url, HttpLoader(), parse_search_result, save_to_db )
The above two code blocks look like pseudo code, but they are workable samples.
In this documentationm. Data, Message, Event are the same thing.
