Using Exceptionless in the NodeJS environment is similar to using it in other JavaScript environments.

To use this package, your must be using ES6 and Node 18+.

npm install @exceptionless/node --save

While your app is starting up, you should call startup on the Exceptionless client. This ensures the client is configured and automatic capturing of unhandled errors occurs.

import { Exceptionless } from "@exceptionless/node";

await Exceptionless.startup(c => {
  c.apiKey = "API_KEY_HERE";

  // set some default data
  c.defaultData["mydata"] = {
    myGreeting: "Hello World"
  };

  c.defaultTags.push("Example", "JavaScript", "Node");
});

Once that's done, you can use the Exceptionless client anywhere in your app by importing Exceptionless followed by the method you want to use. For example:

await Exceptionless.submitLog("Hello world!");

Please see the docs for more information on configuring the client.

For improved stack traces launch your Node app with the --enable-source-maps command line option.

node app.js --enable-source-maps
