A simple package to trace back exception errors on any environment and also give the exact clue to the issue when they happen.
Getting stacktrace in a node application is a little bit laborious expecially on a console or logging systems like cloudwatch. Developers only have access to the exceptions and maybe add extra info in the messages. Clue allows a stack trace of the error, it also recommends possible solutions for this errors and exceptions. This trace can then logged to a more advanced system like elastic search or kanban for better audit
bash npm install trace-back
If you will like to get the stack trace of your application, simple use the errorStackTraceMiddleWare nodejs middleware that has been provided for you.
const stackTraceLogger = errorStackTraceMiddleWare((err, request, response, next) => { logger.error('Error when registering', {
tag: ['CRITICAL', 'SALES`'],
stackTrace: err,
});
return response.json('error has failed'); });
app.use(stackTraceLogger); ``` The errorCalBack parameter in the stacktrace will give you are nice error you can then stream to a logging platform like like AWS cloud watch for your use.
async function bootstrap() {
const app = await NestFactory.create(ApplicationModule);
// Enables dark theme aswell app.useGlobalFilters(new StackTraceExceptionFilter({ errorTrace: (stackTrace: ErrorStackTrace, request, response) => { console.log(errorTrace) }}));
await app.listen(3000);}bootstrap(); ``` Straceback is higly inspired from Laravel Ignition , Nest Js Enligten as well as how developers always find it difficult to trace production bugs on production environment.
