Usage

Application.handleError

The default Stimulus integration is a function that binds to the Application.handleError property. In a new app created using rails new $APP_NAME --webpack=stimulus, for example, your javascript/controllers/index.js file would look something like this:

import { Application } from "stimulus";
import { definitionsFromContext } from "stimulus/webpack-helpers";
 
import Appsignal from "@appsignal/javascript";
import { installErrorHandler } from "@appsignal/stimulus";
 
const appsignal = new Appsignal({
  key: "YOUR FRONTEND API KEY",
});
 
const application = Application.start();
installErrorHandler(appsignal, application);
const context = require.context("controllers", true, /_controller\.js$/);
application.load(definitionsFromContext(context));
