local-microservice
This is a boilerplate for microservices, it includes a basic express server and application performance monitoring (currently using elastic APM).
How to use
npm install local-microservice --save
Define PORT AND ELASTIC_APM_SERVICE_NAME in the corresponding .env file.
PORT=3000
ELASTIC_APM_SERVICE_NAME=local-microservice
In the service's main file setup express as follows:
// make sure you import the microservice after importing environmental variables
import {api, catchAll, startTransaction, startSpan, logError} from 'local-microservice';
api.get('/requesturl', (req, res) => {
const transaction = startTransaction('something');
try {
// do something
transaction.end('success');
} catch (e) {
logError(e);
transaction.end('error');
}
};
catchAll();
