react-native-puree
A log collector for React Native.
Features:
- Buffering: Store logs to AsyncStorage and send them later
- Batching: Send logs in a single request
- Retrying: Retry to send logs after backoff time if sending logs fails
import Puree from 'react-native-puree'
function epochTime () {
return Math.floor(new Date().getTime() / 1000)
}
const puree = new Puree()
puree.addFilter(function addTableName(log) {
return Object.assign({ table_name: 'table' }, log)
});
puree.addFilter(function addEventTime(log) {
return Object.assign({ time: epochTime() }, log)
})
puree.addOutput(async (logs) => {
console.log(logs)
})
puree.start()
// send log
puree.send({ event: 'click', recipe_id: 1234 })
Usage
Configure
const puree = new Puree({
flushInterval: 2 * 60 * 1000, // the interval to flush logs in milli second
maxRetry: 5 // try to send logs until max retry count
firstRetryInterval: 1 * 1000 // the interval between the fail to send logs and the first retry
})
Record logs
puree.send({ event: 'click', recipe_id: 1234 })
A log is stored into persistent storage ( AsyncStorage ) after applying filters to it.
Flush logs
You can automatically send logs every interval with puree.start()
.
puree.start()
or manually:
puree.flush()
Recipe
Flush logs on resume
Use AppState
and puree.flush()
.
