Class Logless

Logless will automatically capture logs and diagnostics for your Node.js Lambda, Google Cloud Function or Express.js service.

Before you integrate the code, you will need to a key. You get it from the Bespoken Dashboard. Once integrated, this is where your logs and data will be viewable.

To use it with Lambdas, simply wrap your function handler, like so:


    var bst = require('bespoken-tools');

    exports.handler = bst.Logless.capture("<SECRET_KEY>", function (event, context) {
        // Lambda code goes here
        context.done(null, "Hello World");
    });

To use it with Google Cloud Functions, simply wrap your function handler:


    var bst = require('bespoken-tools');

    exports.hello = bst.Logless.capture("<SECRET_KEY>", function (request, response) {
        // Cloud Function code goes here
        response.json({ foo: "bar" });
    });

To use it with Express.js, simply configure it with your routes:


    var bst = require('bespoken-tools');

    var logless = bst.Logless.middleware("<SECRET_KEY>");
    app = express();

    app.use(bodyParser.json());
    app.use(logless.requestHandler);

    // Application handlers and routers registered here
    app.post("/", function {
        ...
    });

    // The Logless error handler must be registered last
    app.use(logless.errorHandler);

That's all there is to it. Then you can see all your logs through our handy dashboard!

We will effortlessly capture and format:

  • Request and response payloads
  • Console output (including instrumentation for timing and all debug levels)
  • Error and stack traces

    Returns Function

Static disableConsoleLogging

  • disableConsoleLogging(): void

Static enableConsoleLogging

  • enableConsoleLogging(): void
  • Experimental - this uses monkey-patching to trace console output associated with a transaction on ExpressJS The logs that come back associated with a particular log conversation should not be considered completely reliable at this point. ONLY necessary for ExpressJS.

    Returns void
