I am a front-end developer, and I am glad to chat with you here.
I had the same problem as you before, so I also built many blogs. Recently, I open-sourced a blog project named DevNow based on Astro. You can find it here https://github.com/LaughingZhu/DevNow . The content of the article can be md/mdx. I recommend you to use .mdx, which can better support some advanced features, such as media embed, callout, copy code, etc. The project supports vercel for one-click deployment. You only need to write .mdx content in md format in vscode, and then push it to github. Vercel will redeploy itself. If you are interested, you can try it, but the unfriendly thing is that the comments used in my project are mostly in Chinese. If you are interested, I am happy to provide some help.
