mœwe | typescript client

moewe (german for seagull 🐣) is a open source, privacy preserving crash logging and config platform that can be self-hosted.

motivation

During foss development, I always wished there was a simple platform for crash reporting and knowing roughly how many people are using the software. mœwe aims to be exactly this without the privacy concerns of the large analytics solutions. I hope this is useful to you.

features

• crash logging
• event logging
• user feedback collection
• live config via feature flags
• includes simple UI components for simple integration
  • compatible with React, Angular, Vue, Svelte and more
• let users know about new app versions

usage

initialize the client within your Flutter applications main.dart

// setup Moewe
await new moewe.Moewe({
  host: "open.moewe.app",
  project: "projectId",
  app: "appId",
}).init();

render(...)

That's it 🎉

you can now use the moewe() client within your app:

moewe().events.appOpen({});
moewe().log.debug("this is a debug message");
moewe().crash("an error occurred", null);

// report user feedback
moewe().ui.showFeedbackDialog(); // using package UI
moewe().feedback(...) // manually

// get flag value from server
moewe().config.flagString("fav_food");

feature flags

mœwe allows your client to access variables defined on the server. This makes it possible to:

• let users know whether a new version of your application is available for them
• toggle specific (maybe experimental) features on and off
• do A/B testing

you can access these flags with the following function. Make sure to await the moewe init() call before using feature flags. Otherwise all flags are null

moewe().config.flagString("abc");
moewe().config.flagInt("def");
moewe().config.flagBool("ghi");

crash logging

You can log crashes using the moewe.crash(...) function. You can also use this for wrapping your application
