The discourse-amazon-sns plugin enables push notifications in Discourse forums through Amazon Simple Notification Service (SNS). It’s designed to work in conjunction with a mobile app to deliver push notifications to iOS and Android devices via APNS and GCM/FCM. Amazon SNS handles the communication with each protocol, this plugin ensures that Discourse events (replies, watched topics, PMs, etc.) trigger events in SNS.

Features

  • Push notification support for both iOS (APNS) and Android (GCM/FCM) platforms
  • Device token registration and management
  • Automatic handling of disabled or invalid endpoints
  • Integration with Discourse’s existing notification system
  • Support for React Native webview communication

Requirements

  • AWS account with SNS access
  • Amazon SNS platform applications configured for:
    • iOS (APNS or APNS_SANDBOX)
    • Android (GCM/FCM)
  • AWS credentials with permissions to publish to SNS
  • Mobile application that can register for and receive push notifications

Hi everyone! I’m using Discourse 3.5.2 by discourse/discourse image, and this is the only plugin that causes problems during installation, resulting in a 5xx error in our installation. The error is as follows:

ActionView::Template::Error (The asset 'plugins/discourse-amazon-sns.js' was not found in the load path.)

All assets have already been precompiled by running:

RAILS_ENV=production bundle exec rake assets:precompile

Can you help me understand what might be causing this problem?

Sorry about that. Is this a new error? Meaning, did you already have this plugin installed and it stopped working at some point?

It’s something new, we just introduced the plugin into our installation (we have other plugins and they all work), but then the site gives a 5xx error, and when I check the logs, I see what I sent you. My Dockerfile looks something like this:

FROM discourse/discourse:3.5.2

WORKDIR /var/www/discourse

# Install discourse-amazon-sns plugin
RUN git clone https://github.com/discourse/discourse-amazon-sns.git /var/www/discourse/plugins/discourse-amazon-sns && \
    chown -R discourse:discourse /var/www/discourse/plugins/discourse-amazon-sns

EXPOSE 80

That is an experimental image, and will have plenty of compatibility issues with plugins

Yeah, @caue-pareto, sorry, I think this has to do with that image. I see no issues with this plugin on my self-hosted install following the standard install.
