A simple and colorful logger all types of JavaScript applications.
You can install PrismLogger using npm:
npm install prism-loggerThe 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.
| Function | Use |
|---|---|
| .error() | Logs an error message in red text |
| .success() | Logs a success message in green text |
| .warning() | Logs a warning message in yellow text |
| .red() | Logs a message in red text |
| .green() | Logs a message in green text |
| .yellow() | Logs a message in yellow text |
| .blue() | Logs a message in blue text |
| .magenta() | Logs a message in magenta text |
| .cyan() | Logs a message in cyan text |
| .white() | Logs a message in white text |
| Function | Use |
|---|---|
| .errorBg() | Logs an error message with red background |
| .successBg() | Logs a success message with green background |
| .warningBg() | Logs a warning message with yellow background |
| .redBg() | Logs a message with red background |
| .greenBg() | Logs a message with green background |
| .yellowBg() | Logs a message with yellow background |
| .blueBg() | Logs a message with blue background |
| .magentaBg() | Logs a message with magenta background |
| .cyanBg() | Logs a message with cyan background |
| .whiteBg() | Logs a message with white background |
That's all for the built-in functions. The above functions are availabe in both the loggers. Now let's talk about making your own custom logs.
You can use the .logBg() to create a custom log.
PrismLogger.logBg("Your message", "blue", "white");
// This will create a log with white background and blue textYou can use any of the following colors:
- black
- red
- green
- yellow
- blue
- magenta
- cyan
- white
- gray
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");
