NestJS
The AppSignal for Node.js integration for NestJS.
Installation
NestJS is instrumented automatically by the AppSignal for Node.js package.
When calling nest start
directly, you can use the NODE_OPTIONS
environment variable to require it:
NODE_OPTIONS='--require ./appsignal.cjs' nest start
The start script references the appsignal.cjs
file that was created when configuring AppSignal.
To use AppSignal from the npm
commands generated when creating an application with the nest new
command, modify the following scripts from the scripts
section of your package.json
file as follows:
{ "scripts": { "start": "NODE_OPTIONS='--require ./appsignal.cjs' nest start", "start:dev": "NODE_OPTIONS='--require ./appsignal.cjs' nest start --watch", "start:debug": "NODE_OPTIONS='--require ./appsignal.cjs' nest start --debug --watch", "start:prod": "node --require ./appsignal.cjs dist/main" } }
Features
The NestJS integration will send AppSignal a child span representing the execution time of each middleware, as well as a child span for the request handler.
The name of the controller class and method that handled the request will be used as the name of the action.
Any errors raised by your NestJS application will be reported to AppSignal.
