Description

Telegram bots are quite popular because they are easy to make, easy for people to use, and they come with lots of useful features like verifying who you are, sending messages, making payments, and more.

At the start of this course, you will discover the essential functions of Telegram bots. We'll delve into topics like commands, messages, the different events a bot can handle, reply keyboards, inline keyboards, inline queries, and more. This will show you that the Telegram Bot API is versatile and can be used for many purposes.

Once you get the hang of these functions, you'll be able to build your own bot. We're going to make a bot called the Taboo bot. If you don't know about it, Taboo is a fun board game where you have to explain a word without using certain words that are off-limits. Our bot will let you play Taboo on Telegram. This part of the course is hands-on, closely simulating real-world development. You'll work with technologies like Spring, Hibernate, and PostgreSQL extensively. These are valuable tools for Java developers and are often prerequisites for Java job positions. Enrolling in this course will enhance your job prospects and make you more appealing to potential employers.

In the end, you'll deploy the bot on AWS (EC2) using a somewhat manual process, which is adaptable for deploying on any server. This means that the steps you learn in the final section will generally apply to most VDS/VPS servers of your choice.
