This package assumes a node express application using node-app-base.

• middleware for adding request metrics
• augment application logs with request and session IDs

In the entry point to the application (before passing the logger to any modules), request the logger and initialise using the node-app-base logger. Pass the wrapped logger to any modules that require a logger.

const createRequestLogger = require('express-utils').createRequestLogger;

const {
    config, timers, metrics, logger,
} = require('node-app-base')('my-app');

const requestLogger = createRequestLogger(logger);

const app = require('./app')(
    requestLogger,
);

Once the express app is created, create storeIdsMiddleware and load into the application. If you are using session middleware, make sure the session comes before storing the Ids:

const app = express();

const sessionMiddleware = session();
const storeIdsMiddleware = require('express-utils').createStoreIdsMiddleware();

app.use(sessionMiddleware)
app.use(storeIdsMiddleware);

Pass logger, metrics and timers, along with instructions for linearBuckets to the metricsMiddleware and attach using app.use.

const app = express();

const metricsMiddleware = require('express-utils').createMetricsMiddleware(logger, metrics, timers, [5, 5, 5]);

app.use(metricsMiddleware);
