Package Exports

seq-logging

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (seq-logging) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Seq Logging for JavaScript

This library makes it easy to support Seq from Node.js logging libraries, initially node-bunyan. It is not expected that applications will interact directly with this package.

Usage

A Logger is configured with serverUrl, and optionally apiKey as well as event and batch size limits.

let process = require('process');
let seq = require('seq-logging');

let logger = new seq.Logger({ serverUrl: 'http://localhost:5341' });

logger.emit({
    timestamp: new Date(),
    level: 'Information',
    messageTemplate: 'Hello for the {n}th time, {user}!',
    properties: {
        user: process.env.USERNAME,
        n: 20
    }
});

logger.close();

Events are sent using the emit() method, that internally performs asynchronous batching based on payload size.

When the application exits, close() ensures all buffered events are written. This can be done at any time otherwise using the flush() method. Both of these methods return promises indicating completion.
