@eyegym/structured-log-seq-sink v0.6.3

A structured-log plugin that writes log events to Seq.

Requires polyfills for Promise and fetch if those aren't supported in your target platform/browser.

Installation

npm i @eyegym/structured-log-seq-sink --save

Usage

var structuredLog = require("@eyegym/structured-log");
var seqSink = require("@eyegym/structured-log-seq-sink");

var logger = structuredLog
  .configure()
  .writeTo(
    seqSink({
      /* ... options ...  */
    })
  )
  .create();

Available options

Dynamic Level Control

Much like Serilog's Dynamic Level Control via Seq, Seq can be used to dynamically control the log level of structured-log. To configure, setup a DynamicLevelSwitch and pass it to the sink:

var levelSwitch = new structuredLog.DynamicLevelSwitch("info");
var log = structuredLog
  .configure()
  .minLevel(levelSwitch)
  .writeTo(
    SeqSink({
      url: "http://localhost:5341",
      apiKey: "API_KEY",
      levelSwitch: levelSwitch,
    })
  )
  .create();

This can be used as the log level across the entire pipeline (by using .minLevel(levelSwitch), or just for the seq sink (by passing it in the options array).

Building and testing

To build the modules yourself, you need Node 8 or greater. Check out the code, then install dependencies and run the build script:

npm i
npm run build

Then, you can test the bundled module by running:

npm test
