Package Exports
- prism-logger
- prism-logger/dist/index.js
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 (prism-logger) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
PrismLogger
A simple and colorful logger all types of JavaScript applications.
Installation
You can install PrismLogger using npm:
npm install prism-loggerUsage
The package provides two different Loggers - PrismLogger for NodeJs applications and ConsoleLogger for browser consoles. You may use any one based on your project requirements, but the usage is same for the both of them.
- Import the
PrismLoggerclass from prism-logger
import { PrismLogger } from "prism-logger";- Use the varius log functions provided. For instance,
PrismLogger.yellow("This will be printed in yellow");
// The yellow() logs the text in yellow fontNOTE: PrismLogger has static methods so you don't need to create an object but for ConsoleLogger an object has to be created with a boolean parameter named 'debug'. This will determine whether the logs will show up in the console. This will be particulary useful when you need to show some logs in development for dubugging but you don't want them in produnction environment. Setting the debug value to 'false' in production will remove all logs.
Pretty simple, right? Well that's the purpose of this package. There's also a way to make your own custom logger. But let's discuss it later.
First let's dicuss other built-in log functions.

Examples
import { PrismLogger, ConsoleLogger } from "prism-logger";
const logger = new ConsoleLogger((debug = true)); // the boolean variable debug determines whether the logger will log anything
logger.log("Hello, world!", "cyan");
logger.error("Something went wrong");
logger.success("Task completed successfully");
logger.warning("Be cautious!");
logger.logBg("This is a log with custom colors", "white", "blue");
logger.errorBg("This is an error with red background");
