React Native - npx instrumentdynatrace
When using a React Native app, when first setting up Dynatrace for it, you’ll need to run:
npx instrumentdynatrace
This is not necessarily a one-and-done command.
What does the command do and when to run it?
When running the command npx instrumentdynatrace, the command will take the configurations from dynatrace.config.js, takes each portion (iOS and Android), and copies it to the correct file in their respective OS folders.
You must run this command every time you make any changes to the dynatrace.config.js. Without using the command, changes will not take affect.
Once you have run the command, you can view the configuration from the dynatrace.config.js in its respective OS folder:
For Android:
You should be able to see the changes in the dyantrace.gradle
{project name}/node_modules/@dynatrace/react-native-plugin/files/dynatrace.gradle
For iOS:
You should be able to see the change in the p.list.
{project name}/ios/{project name}/Info.plist
Once the command npx instrumentdynatrace has been ran, you can view the change from the terminal:
If you made changes and it was successful:
You should be able to see that for both OSs, that the configuration has been updates

If no changes were made to the dynatrace.config.js
For Android, the gradle file will be written, but since nothing change, the output will be the same.
For iOS, the plugin is aware that the p.list is the same and does not make any further changes to the p.list
