Your personal butler on discord.

About

This is a fun purpose project made using nodejs with TypeScript. It uses the Discord.js library to connect with the discord api and interprete the given commands. Also, it consumes two external services to provide gif and news fetching!

Technologies

• Nodejs
• TypeScript
• Discord.js
• @giphy/js-fetch-api
• ts-newsapi
• Tsyringe

Implemented patterns and principles

• Dependency Injection
• S and D from SOLID

Commands

Currently, the bot only responds to these commands:

$gif searchTerm - which, of course, sends the fetched gif to the current channel

$news [--country] searchTerm - which fetches and retrives some links (max to 5) to headlines on news platforms

ps: the argumet --country should be replaced for a to etter representation of a country, such as us, br, uk and so forth. Besides, since it is optional, the default value is br, which fetch news on brazillian vehicles.

Project requirements

Connecting with external services is awesome, but it has it's trade-offs. If you check the .env.example file, you should find the necessary tokens to connect to those platforms. Make sure to get all of the listed keys and to create a .env file on the root dir to have access to the command functionalities.
