Sesam microservice utils

SesamUtils

Python module to simplify common tasks when developing microservices for the Sesam integration platform.

Usage examples

Environment Variables

from sesamutils import VariablesConfig
import sys

required_env_vars = ["username", "password", "hostname"]
optional_env_vars = ["debug", ("auth_type", "user")] # Default values can be given to optional environment variables by the use of tuples

config = VariablesConfig(required_env_vars, optional_env_vars=optional_env_vars)

if not config.validate():
    sys.exit(1)


print(config.username)

Dotdictify

from sesamutils import Dotdictify

example_dict = {
    "test": {
        "my_thing": "hello"
    }
}

dot_dict = Dotdictify(example_dict)

print(dot_dict.test.my_thing)

# hello

Profiler

You can use this (A profiling decorator) to see complete details of execution time taken by a function in your program. Based on that, you can optimize your python code if required.

from sesamutils import profiler

@profiler
def <Name of your method>():
    <your method definition>

# Apply to any function with @profiler
# Profiles the function using cProfile, and prints out a report to screen.
# belwo are few lines for illustration  purpose.

Sesam Logger

You can use this to save time and lines of code. It provides the standard customization of root level logging- configuration and gives you SESAM uniform standard settings.

from sesamutils import sesam_logger

logger = sesam_logger('<name of your module or logger>')

# User can provide environment variable "LOG_LEVEL" with valid values else log level will be 'INFO' by default.
# While logging to screen, timestamp is set to false by default, since sesam-node has it's own. 
# However if you want to make it enable, then you just need to create instance like this:  
      logger = sesam_logger('<name of your module or logger>', timestamp=True)     

Installation

pip install sesamutils
