ThingsDB module builder

Project description


Library for creating ThingsDB modules using the Python language


$ pip install py-timod


Modules for ThingsDB read from stdin and write a response back to stdout. Work by the module must be non-blocking.

If the module requires configuration data, for example a connection string, then this configuration will be send immediately after start-up but may be received again when the module configuration is changed in ThingsDB.

Do not use functions like print since these function will write to stdout and this is reserved for ThingsDB. Instead, use logging... to write to stderr instead.

The following code may be used as a template: (see:

import logging
from timod import start_module, TiHandler, LookupError

class Handler(TiHandler):

    async def on_config(self, cfg):

    async def on_request(self, req):
        if 'message' not in req:
            raise LookupError('missing `message` in request')

        return req['message']

if __name__ == '__main__':
    start_module('demo', Handler())
