Dependencies

Requires Node.js 10.x or later, and Axios http client. No other dependencies to conflict with your app.

Installing With npm

npm install resurfaceio-logger --save

Logging From Express Middleware

After installing the module, add a HttpLoggerForExpress instance to your app, after any body parsers in use.

const express = require('express');
const app = express();

// add body parsers

const resurfaceio = require('resurfaceio-logger');
resurfaceio.HttpLoggerForExpress.add(app, {
    url: 'http://localhost:7701/message', 
    rules: 'include debug'
});

// define routes

Logging From Koa Middleware

After installing the module, add a HttpLoggerForKoa instance to your app, after any body parsers in use.

const Koa = require('koa');
const app = new Koa();

// add body parsers

const resurfaceio = require('resurfaceio-logger');
resurfaceio.HttpLoggerForKoa.add(app, {
    url: 'http://localhost:7701/message', 
    rules: 'include debug'
});

Logging From Apollo Server on Express

After installing the module, add a HttpLoggerForExpress instance before calling applyMiddleware.

const app = express();

const resurfaceio = require('resurfaceio-logger');
resurfaceio.HttpLoggerForExpress.add(app, {
    url: 'http://localhost:7701/message', 
    rules: 'include debug'
});

const server = new ApolloServer({ ... });

server.applyMiddleware({ app });

Logging From Specific Express Routes

After installing the module, create a logger and call it from the routes of interest.

const express = require('express');
const app = express();

const resurfaceio = require('resurfaceio-logger');
const logger = new resurfaceio.HttpLogger({
    url: 'http://localhost:7701/message',
    rules: 'include debug'
});

app.get('/', function (request, response) {
    response.render('pages/index', function (e, html) {
        response.status(200).send(html);
        resurfaceio.HttpMessage.send(logger, request, response, html);
    });
});

Logging With API

Loggers can be directly integrated into your application using our API. This requires the most effort compared with the options described above, but also offers the greatest flexibility and control.

API documentation

Protecting User Privacy

Loggers always have an active set of rules that control what data is logged and how sensitive data is masked. All of the examples above apply a predefined set of rules (include debug), but logging rules are easily customized to meet the needs of any application.
