Now, we are ready to start coding. I would split the code application into sections and for each section, I would explain the code and provide helpful comments I have.

Settings service

This is the service responsible for providing the configurations for the entire system.

Steps:

  1. create a config Folder below src/app/.

explanation:

  1. Here we define the interface IConfigManager Which will provide the required configuration settings.

Twitter service

This is the service responsible for integrating with Twitter APIs. It wraps around Twitter APIs – the ones we need in our project – and displays them in a specific language for a specific domain (DSL).

Steps:

  1. create a twitter Folder below src/app/.

explanation:

  1. Here we define the interface ITwitterService Which will provide the WatchToFilterStream function.
import "reflect-metadata"; import  inject, injectable  from 'inversify'; import  ConfigManagerLocator, IConfigManager  from './../config/config-service'; import Twit from 'twit';

Twitter bot service

This is the service responsible for wrapping the main bot module.

Steps:

  1. create a twitter-bot Folder below src/app/.

explanation:

  1. Here we define the interface ITwitterBot Which will provide the Initialize function.
