Undead Logging

Logging for stupid idiots like me

import Logging from "@proxnet/undead-logging"

const log = new Logging("Main");

log.i("Hello World!");

Disable a source:

// .. logging source is in the scope
log.visible = false;

log.debug("I can't be seen!");

// no output

Change a source's name:

// .. logging source "Main" is in the scope

log.n("Network is networking");
log.source = "Main2";
log.n("Something happened");

// output:
// 2024-11-14T01:21:40.350Z Main [NETWORK] Network is networking
// 2024-11-14T01:21:40.350Z Main2 [NETWORK] Something happened

Disable a type of message globally:

import Logging, { MessageTypeVisibility } from "@proxnet/undead-logging";
// .. logging source "Main" is in the scope

MessageTypeVisibility.Error = false;

// somewhere else, could be a different script
log.i("I am visible");
log.error("I am not visible");

// output:
// 2024-11-14T01:21:40.350Z Main [INFO] I am visible

Event Listeners

Event listeners are called when a message is logged on any logging source

An event callback can either receive messages as either:

• Whole lines, including formatting, colors, excluding newlines or
• Individual msg (string), type (MessageType), source (string), and time (Date) arguments

Callback ran when a message is logged anywhere:

LoggingListeners.onmsg('basic', msg => {
    // `msg` is a string containing the entire line w/ formatting
});

Callback ran when a message is logged anywhere (this time components are split up):

LoggingListeners.onmsg('type', (msg, type, source, time) => {
    // msg: string
    // type: MessageType - import { MessageType } from "@proxnet/undead-logging";
    // source: string
    // time: Date
});

Remove callback:

const cb = msg => { /* do something with msg: string */ };
LoggingListeners.onmsg('basic', cb);
LoggingListeners.offmsg('basic', cb);

Time display modes

You can display four different formats for time:

• UTC
• Unix time (in milliseconds)
• Local [process] time (in milliseconds, from the performance API)
• RoundedLocal: Same as above, but rounded to the nearest whole ms

Set the time format:

import { LoggingConfiguration, TimeFormat } from "@proxnet/undead-logging";

LoggingConfiguration.timeFormat = TimeFormat.Local;
// or
LoggingConfiguration.timeFormat = TimeFormat.Utc;

(advanced) Logging timing

You can control when log functions are executed using LoggingConfiguration.logTiming.

Logs are sent synchronously by default. You can optionally defer logs with setImmediate using LogTiming.Deferred

LoggingConfiguration.logTiming = LogTiming.Sync;
// or
LoggingConfiguration.logTiming = LogTiming.Deferred;
