Package Exports

ts-log-debug
ts-log-debug/lib/layouts/utils/colorizeUtils

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 (ts-log-debug) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Breaking change 3.x

Since v3.x, the logger is completely rewritten to support new features. This new version is inspired by the excellent project log4js.

Quick start

Minimalist version:

import {$log} from "ts-log-debug";
$log.level = "debug";
$log.name = "APP";

$log.debug("Some debug messages");

Will be procude the following log output:

[2017-06-17 11:43:37.987] [DEBUG] [APP] - Some debug messages

Create your custom logger:

import {Logger} from "ts-log-debug";

const logger = new Logger("loggerName");
logger.appenders
    .push({
        type: "stdout",
        levels: ["debug", "info", "trace"]
    })
    .push({
        type: "stderr",
        levels: ["fatal", "error", "warn"],
        layout: {
          type: "pattern",
          pattern: "%d %p %c %X{user} %m%n"
        }
    })
    .push({
        type: "file",
        filename: `${__dirname}/app.log`,
        layout:{
            type: "json",
            separator: ","
        }
    })
