restify-request-logger.js

this.server.pre((req, res, next) => {
    this.logger.debug(`Start ${req.method} ${req.url}`);
    const requestStart = process.hrtime();
    res.on('finish', () => {
        const [reqTimeS, reqTimeNS] = process.hrtime(requestStart),
        requestDurationMS = (reqTimeS * 1e3 + reqTimeNS / 1e9).toFixed(2);
        this.logger.debug(`End ${req.method} ${req.url} (status=${res.statusCode} duration=${requestDurationMS}ms)`);
    });
    next();
});
