在 ReactJS MySQL Node.js 和 Express 中完成的论坛的查询问题

Question

I am a junior developer and right now I'm building a simple forum using ReactJS, Node.js, Express and MySQL.

In the forum each Topic must have many many Posts.

I do not know if the problem comes from the back-end query or if it comes from the client side but the posts aren't well separated per topic. Right now I have all the posts from the posts table in topic 1 and again in topic 2.

Test Page

In the server folder here are my imports in index.js

Server side imports

and here are my queries for Posts.

Thank you for any help.

Have a very nice day, Ana

Answer 1

Your query seems ok, which will return all records by inner join with topics table. One more suggestion, use the below code to get the proper HTTP response code.

return res.status(200).send(result);

Also, use try...catch to handle exceptions as well.
