@appsignal/reactAppSignal.com websiteDocumentationSupportThe @appsignal/javascript integration for React v15+.See also the mono repo README for more information.InstallationAdd the @appsignal/react and @appsignal/javascript packages to your package.json. Then, run yarn install/npm install.You can also add these packages to your package.json on the command line:yarn add @appsignal/javascript @appsignal/reactnpm install --save @appsignal/javascript @appsignal/reactUsageError BoundaryIf you are using React v16 or higher, you can use the ErrorBoundary component to catch errors from anywhere in the child component tree.import React from "react"import ReactDOM from "react-dom"import Appsignal from "@appsignal/javascript"import { ErrorBoundary } from "@appsignal/react"const appsignal = new Appsignal({ key: "YOUR FRONTEND API KEY"})const FallbackComponent = () => ( div>Uh oh! There was an error :(div>)const App = () => ( ErrorBoundary instance={appsignal} fallback={(error) => FallbackComponent />}> { /** Child components here **/} ErrorBoundary>)ReactDOM.render(App />, document.getElementById("root"))Legacy Boundary⚠️ WARNING: The API that this component uses is unstable at this point in React's development. We offer this component as a means to support those running React v15, but do not guarantee its reliablity. You are encouraged to use the ErrorBoundary whenever possible.The LegacyBoundary works in almost exactly the same way as the ErrorBoundary:import React from "react"import ReactDOM from "react-dom"import Appsignal from "@appsignal/javascript"import { LegacyBoundary } from "@appsignal/react"const appsignal = new Appsignal({ key: "YOUR FRONTEND API KEY"})const FallbackComponent = () => ( div>Uh oh! There was an error :(div>)const App = () => ( LegacyBoundary instance={appsignal} fallback={(error) => FallbackComponent />}> { /** Child components here **/} LegacyBoundary>)ReactDOM.render(App />, document.getElementById("root"))DevelopmentInstallationMake sure mono is installed and bootstrapped, see the project README's development section for more information.You can then run the following to start the compiler in watch mode. This automatically compiles both the ES Module and CommonJS variants:You can also build the library without watching the directory:yarn build # build both CJS and ESMyarn build:cjs # just CJSyarn build:esm # just ESMTestingThe tests for this library use Jest as the test runner. Once you've installed the dependencies, you can run the following command in the root of this repository to run the tests for all packages, or in the directory of a package to run only the tests pertaining to that package:VersioningThis repo uses Semantic AppSignal helps your team communicate without any effort, keeping allcommunication and context in one place.

New Error("Oops");};const funcTwo = async () => { await Promise.resolve(); await funcThree();};const funcOne = async () => { await new Promise((resolve) => setTimeout(resolve, 10)); await funcTwo();};const init = async () => { await new Promise((resolve) => setTimeout(resolve, 10)); await funcOne();};init().then( () => console.log("success"), (error) => console.error(error.stack));">This results in an output like so:If we run the same code on a version of Node.js older than 12, the output looks like this:">In this case, at isn’t very helpful in revealing the full context of the error.However, this works differently with async stack traces. When an error occurs in a callback function, the call stack is captured at the point when a callback is scheduled (the init() function in this case), rather than when it is executed.Set Up AppSignal for Your Express.js AppAppSignal can assist you in identifying and troubleshooting problems with your app, including issues related to slow performance, errors, crashes, and downtime. You can resolve these issues quickly before they negatively impact your users.In this tutorial, we will walk you through how to integrate AppSignal into your Express.js app.Note: You can follow along with the source code for the following tutorial here.Firstly, sign up for an account on appsignal.com and create a new app by following these guides.Then start a new Node.js project:Install AppSignal for Node.js:In your repo’s root directory, create an appsignal.cjs file and paste the following code to require and configure AppSignal:Note: An application's Push API key is given during setup and can be found in the App settings > Push & deploy tab.In your package.json file, edit the start script to load AppSignal's configuration before any other library using the --require flag, like so:Integrating AppSignal into your Express app is very easy. You just need to require the expressErrorHandler module and then use it in your app with app.use, as shown below:The expressErrorHandler module consists of middleware designed to forward any errors in your Express application to AppSignal.Tracking Async Callback Errors with AppSignalLet's create an error inside an asynchronous callback to see how AppSignal handles it: { await Promise.resolve(); throw new Error("Oops");};const funcTwo = async () => { Key NestJS monitoring featuresError trackingTrack NestJS errors and receive alerts when they occur.

If not properly handled.Complexity: It can be more difficult to navigate and analyze a larger stack trace, particularly for complex applications.With that in mind, you should use a reasonable limit that provides the necessary information without causing performance issues.Wrapping UpIn this post, we've seen how async stack traces in Node.js can help you debug and trace errors in your asynchronous code by capturing call stacks.We also explored how integrating AppSignal into your Node.js application makes it a lot easier to detect and resolve async callback errors in real time.Finally, we discussed how expanding stack trace size in Node.js can offer more insights into the execution of your code and help you understand an error's context. However, it's important to use this feature judiciously, taking into account its possible impact on performance, memory usage, security, and navigability.Happy coding!P.S.
