Initial setup issues

npm install hangs

Downgrade to version 5.5.1: npm install -g npm@5.5.1.

re-natal missing

Create a link: ln -sf node_modules/re-natal/index.js re-natal

react-native run desktop complaining about missing qmldir:

Error copying directory from "/path-to-status-react/node_modules/react-native/ReactQt/runtime/src/qmldir" to "/path-to-status-react/desktop/lib/React".
make[2]: *** [lib/CMakeFiles/copy-qmldir] Error 1
make[1]: *** [lib/CMakeFiles/copy-qmldir.dir/all] Error 2
make: *** [all] Error 2

Can be solved by re-running npm install react-native which put the ReactQt/runtime/src/qmldir file back.

Missing web3 package issue

After last upgrade of react-native-desktop to the v.0.53.3 of original react-native appeared some incompatibility between react-native and web3 packages on npm install. Initially it installed usually fine, but after react-native desktop command execution web3 package is get removed from node_modules. Manual install of web3 by npm install web3 installs web3 package, but removes react-native package. Workaround or solution?

Related to https://github.com/rjeczalik/notify/issues/139. Solution: re-run.

App issues

Node server crashing

node ./ubuntu_server.js log:

DEBUG [status-im.utils.handlers:36] - Handling re-frame event:  :signal-event {"type":"node.crashed","event":{"error":"node is already running"}}
DEBUG [status-im.ui.screens.events:350] - :event-str {"type":"node.crashed","event":{"error":"node is already running"}}
DEBUG [status-im.utils.instabug:8] - Signal event: {"type":"node.crashed","event":{"error":"node is already running"}}
DEBUG [status-im.ui.screens.events:362] - Event  node.crashed  not handled

Solution: prevent starting Node when there is an instance already running.

Reload JS - blank screen

Console log for react-native run-desktop shows error 533. Solution: reload again. Still, might hang at Signing you in... step (due to node attempted to be restarted). Re-run Figwheel and react-native run-desktop

ReactButton.qml non-existent property "elide" error upon startup

qrc:/qml/ReactButton.qml:33: Error: Cannot assign to non-existent property "elide"
"Component for qrc:/qml/ReactWebView.qml is not loaded"
QQmlComponent: Component is not ready
"Unable to construct item from component qrc:/qml/ReactWebView.qml"
"Can't create QML item for componenet qrc:/qml/ReactWebView.qml"
"RCTWebViewView" has no view for inspecting!

Reload JS does not help, restarting Figwheel/react-native might not as well. Restarting Metro bundler solved it for me.

After login when several contacts are available: realm errors

  1. attempting to create an object of type 'chat'...
  2. attempting to create an object of type 'transport'...
  3. Error text containing only the public key. The realm stack trace follows.

inotify errors

upon running npm start on linux, watchman may indicate: "The user limit on the total number of inotify watches was reached"

This can be fixed by running the below command. Note, changes will only be as valid as the current terminal session.

echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_user_watches && echo 999999 | sudo tee -a
/proc/sys/fs/inotify/max_queued_events && echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_user_instances &&
watchman shutdown-server && sudo sysctl -p

metro bundler caching issue

Time to time metro bundler for some reasons doesn't recognize changes in JavaScript sources and returns old version of the files on react-native app request. Cleaning of cache should help to solve the issue (usually running react-native start --reset-cache to start the bundler should work) .

On Linux metro bundler saves cache to the following directories (can be removed manually): /tmp/metro-cache-*
