nocl

Styled nodejs console logger

Installation

npm i nocol

Usage

import nocl, { Nocl } from "nocol";

nocl.log("Hello world!");

Default export: nocl - an instance of Nocl class

Create new instance

const nocl2 = new Nocl(options);
nocl2.log("Hello world from nocl2!");

Class init options / properties

You can also modify the properties directly to change the styling without creating new instance

name	type	default	description
symbolPrefix	object		Symbol to be prepend to theme's symbol
symbolPostfix	object		Symbol to be append to theme's symbol
encloseSymbol	boolean	true	Enclose symbol with square brackets
useChalkTemplate	boolean	false	Color text with chalk template
theme	object	DefaultTheme	Logging theme style object

Examples

Modifying theme

This will merge into current instance theme

nocl.info("default theme");
const theme = {
  info: {
    symbol: "info",
    symbolColor: "#074880",
  },
};
nocl.theme = theme;
nocl.info("modified theme");
// OR
const nocl3 = new Nocl({
  theme,
});
nocl3.info("modified theme from nocl3");

Modifying theme: ts

Change timestamp display

nocl.ts("default theme: ts");
nocl.theme = {
  ts: {
    // type LocalesArgument
    locales: undefined,
    // type DateTimeFormatOptions
    options: {
      hour12: true,
      timeStyle: "medium",
    },
  },
};
nocl.ts("modified theme: ts");

Using symbolPrefix

nocl.log("without symbolPrefix");
nocl.symbolPrefix = {
  symbol: "1/10",
};
nocl.log("with symbolPrefix");

Using symbolPostfix

nocl.log("without symbolPostfix");
nocl.symbolPostfix = {
  symbol: "username",
};
nocl.log("with symbolPostfix");

Using encloseSymbol

nocl.info("with encloseSymbol");
nocl.encloseSymbol = false;
nocl.info("without encloseSymbol");

Using useChalkTemplate

This will fallback to chalk if there was an error coloring using template

nocl.log("{yellow without using chalk template}");
nocl.useChalkTemplate = true;
nocl.log("{yellow using chalk template}");

Using session log

nocl.startSession(filepath, options); // createWriteStream
nocl.log("hello");
nocl.endSession();
