react-native-source-maps

Utilities to easily add support of Source Maps to your React Native project

----------
#### Usage:
1) Add sourcemaps generation to your build script (or customize default one)
``
...
--sourcemap-output "$DEST/main.jsbundle.map"
`


2) Initialise at the app start with source map bundle file and other options
`
import {initSourceMaps} from 'react-native-source-maps';
initSourceMaps({sourceMapBundle: "main.jsbundle.map", collapseInLine: true});
`

3) Use it with your logging utilities
Example:
`
const stack = !__DEV__ && await getStackTrace(error);
if (stack) {
error.stack = stack;
}
log.error({message: 'Error (' + error.message + ')', error});
`

4) To caught all uncaught errors in app you can add global error handler:
`
import log from "../log";
import {getStackTrace} from 'react-native-source-maps';
import ErrorUtils from "ErrorUtils";

(async function initUncaughtErrorHandler() {
const defaultGlobalHandler = ErrorUtils.getGlobalHandler();

ErrorUtils.setGlobalHandler(async(error, isFatal) => {
try {
if (!__DEV__) {
error.stack = await getStackTrace(error);
}
log.error({message: 'Uncaught error (' + error.message + ')', error, isFatal});
}
catch (error) {
log.error({message: 'Unable to setup global handler', error});
}

if (__DEV__ && defaultGlobalHandler) {
defaultGlobalHandler(error, isFatal);
}
});
})();
