Is it worth it to do the entire server part on express js?

Question

Python

mysql database. I want to use express.js on the server. How bad is a memory leak problem?
The server is required to get data from the database and send it to the client in json format.
Previously, I used python for such tasks.
I wanted to consider the js option, since it is inconvenient to constantly switch from one language to another (back-end -- front-end)

Answer 1

According to the experience of a moderately loaded project, 100-1000 API requests per minute,
having 2 services in Python and NodeJS, we got that, in principle, everything works fine.
Restarting the server when it crashes is necessary in any case, regardless of whether it is python or nodejs.
In nodejs, use nodemon or forever for this for example.
P.S. Naturally, work with the database is many times more active than queries, moreover, there are several databases.
