After upgrading my app to the newest version of react native 0.73.x, I encountered an issue where the UI on iOS starts freezing and becoming unresponsive in production. The main screen loads react-native-maps with numerous markers, and this was not a problem prior to the update. Do you have any thoughts or suggestions on how to resolve this performance issue?
I was able to successfully resolve the issue by revising the map setup and code. I ensured that the map markers were only rendered once, cleaned up the connected states, and ignored any updates to external states that should not affect the markers (such as region updates). Instead of causing re-renders with each region update (such as user drag actions), I dispatched the new region via Redux and accessed the state only where needed.
So, it turns out that RN 0.73 was not related to the issue at all.const { json } = require('express/lib/response'); const mysql=require ('mysql'); const express=require('express'); var app=express(); const bodyparser=require('body-parser'); app.use(bodyparser.json()); var mysq ...
