Slack Clone Coding [Real-time Chat with React]

It's really great. It covers a lot of the overall front-end technology. The answers are almost like Slack clone coding, so they're quick to the point of real-time socket communication, so communication is really good. If you listen to Zerocho's free React lecture and listen to this, you'll get a lot out of it.

I haven't finished the lecture yet, but I think it's a good enough lecture, and I'm writing it in advance because a pop-up popped up on Inflearn asking me to write a course review. First of all, as the course introduction says, it uses TypeScript, but you can think of it as a React, Webpack, SWR, Emotion, and Socket.IO course. If you're taking the course to study React + TypeScript, you might be a little disappointed. On the other hand, even if you don't know TypeScript, there's no problem taking the course. However, I recommend the All-in-One TypeScript course, and I think it's a good course for those who want to study React + TypeScript while also using TypeScript. First of all, since it's a lecture that's faithful to React, it's good for setting up React structure and development direction. Second, it tells you the initial settings of Webpack and starts, but even if you don't know it, you can still develop, but since I think the initial settings are really important later, the content on the initial settings was really good. Third, it was good that it suggested which units to create style components in when applying styles and proceeded with the class as is. Lastly, it was good to give basic explanations and tips on socket communication, but I can't give you a definitive answer because I'm listening to it now. The downside is that, in my opinion, it's been a while since the lecture came out, so there are a lot of changes in the code. However, since they are consistently uploading updated codes to GitHub, and if you have any difficulties, you can ask questions on the Inflearn Q&A board or Slack and they will answer quickly, so if you want to study on your own, you can sufficiently supplement it. I'm listening while reflecting the contents of GitHub react-query in parallel with the lecture contents, and I was able to search and solve the contents that changed due to library updates. Lastly, as for the lecture listening tip, for the initial setup, there are some changes, so instead of following along, copy and paste the GitHub code, listen to the lecture step by step, and try setting it up on your own, I think it's a good idea. Also, since it's a basic lecture, if you're already using React and TypeScript well in practice and have experience applying socket communication, there may be less content than you think. Personally, I gained a lot from it, so it was a good lecture experience.

Originally, I thought I wasn't suited for online lectures because there weren't many solid lectures.... But I'm currently taking this course and it's really fun.

I will buy all the other lectures too Why did I only find out about zerocho now?

You can learn how to set up a React development environment without CRA. You can gain know-how on front-end development. It was a lecture that made me feel like I was working on a project as a front-end developer because back-end materials were prepared. Thank you.

Personally, I feel like the lectures have improved and become better. I am very satisfied because you teach me properly what you need to know and leave out what you need to leave out. I really learn a lot ㅎㅎ I have benefited a lot from Zerocho in my personal projects and company work. I am also looking forward to the upcoming nuxt lectures!!! Thank you :)

Even if you follow the instructions as they are, you will get lost because the library versions have changed, but they consistently provide answers and there are updates and solutions posted in the notices, which is very helpful when solving problems.

I took the free React lecture by Zerocho and liked it so much. I used to study React by myself because I used to make internal tools at my company, but I learned a lot by watching how other people do it. However, here are some of the disadvantages. - Front-end libraries keep getting updated, so there are some parts that don't work well just by watching the lecture. I thought it would be better to just fix the version and teach, but on the other hand, I think it's better to learn with the latest version even if you look it up yourself. - Since it's clone coding, there's a lot of code, so it's not easy to follow along while typing out all the code in the lecture. This is... Since I have to implement the details of Slack, there's a lot of code specific to that function rather than code for studying the front-end. Those who are planning to take the class should be aware of this and listen to it so that it doesn't get boring. LOL Still, I learned a lot of useful things. When doing a React project, how to set up the basics, what the essential libraries are, what libraries are useful for detailed parts, TypeScript-related tips, how to use web sockets, and basic patterns. I think I learned a lot from just one lecture. That's why I think it's a good lecture.
