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 $APP_NAME --webpack=stimulus
, for example, your javascript/controllers/index.js
file would look something like this:
import { Application } from "stimulus"; import { definitionsFromContext } from "stimulus/webpack-helpers"; import { appsignal } from "./appsignal"; import { installErrorHandler } from "@appsignal/stimulus"; const application = Application.start(); installErrorHandler(appsignal, application); const context = require.context("controllers", true, /_controller\.js$/); application.load(definitionsFromContext(context));
