javascript - Development server of create-react-app does not auto refresh -


i following tutorial on react using create-react-app. application created create-react-app v1.3.0

create-react-app my-app

the dev server run by

npm start

after changing code several times, browser not updated live / hot reload changes. refreshing browser not help. stopping dev server , starting on again capture new changes code.

have seen “troubleshooting” section of user guide?
describes a few common causes of problem:

when save file while npm start running, browser should refresh updated code.

if doesn’t happen, try 1 of following workarounds:

  • if project in dropbox folder, try moving out.
  • if watcher doesn’t see file called index.js , you’re referencing folder name, need restart watcher due webpack bug.
  • some editors vim , intellij have “safe write” feature breaks watcher. need disable it. follow instructions in “working editors supporting safe write”.
  • if project path contains parentheses, try moving project path without them. caused webpack watcher bug.
  • on linux , macos, might need tweak system settings allow more watchers.
  • if project runs inside virtual machine such (a vagrant provisioned) virtualbox, create .env file in project directory if doesn’t exist, , add chokidar_usepolling=true it. ensures next time run npm start, watcher uses polling mode, necessary inside vm.

if none of these solutions please leave comment in thread.

i hope helps!
