Installation

Installing Appsignal for Node.js

In order to auto-instrument modules, the Appsignal module must be both required and initialized before any other package.

First, sign up for an AppSignal account and add the @appsignal/nodejs package to your package.json. Then, run yarn install/npm install.

You can also add these packages to your package.json on the command line:

1
2 yarn add @appsignal/nodejs
npm install --save @appsignal/nodejs

You can then import and use the package in your bundle:

1
2
3
4
5
6
7 const { Appsignal } = require("@appsignal/nodejs")

const appsignal = new Appsignal({
  active: true,
  name: "<YOUR APPLICATION NAME>",
  apiKey: "<YOUR API KEY>"
})

Uninstalling Appsignal for Node.js

Uninstall AppSignal from your app by following the steps below. When these steps are completed your app will no longer send data to the AppSignal servers.

In the package.json of your app, delete all lines referencing an appsignal package: "*appsignal/*": "*".
Run npm install or yarn install to update your package.lock/yarn.lock with the removed packages state.
- Alternatively, run npm uninstall @appsignal/<package name> or yarn remove @appsignal/<package name> to uninstall an AppSignal package.
Remove any AppSignal configuration from your app.
Commit, deploy and restart your app.
- This will make sure the AppSignal servers won't continue to receive data from your app.
Finally, remove the app on AppSignal.com
