Logger

RCE.JS includes it's own logger for information, warnings, debugging and errors. You can learn how to configure the logger here!

Configuration

By default the logger is set to ignore debugging to keep your logs less clustered, however you can change how the logger works.

The following log levels are available to set:

None | Info | Warn | Error | Debug

None - this will completely disable the logger

Info - this will log all important information, include warnings and errors

Warn - this will log only warnings and errors

Error - this will only log errors

Debug - this is the highest logger level and will log everything including debugging

By default, the log level is Info when no value is provided

Log File

Optionally, you may also provide a file-name to log ALL content to, this is very useful for debugging! Simply provide a "file" parameter in the LoggerOptions.

TypeScript

import { RCEManager, LogLevel } from "rce.js";

const rce = new RCEManager({
    logger: {
        level: LogLevel.Info,
        file: "rce.log"
    }
});

JavaScript

Custom Logger

This will only work for TypeScript

For TypeScript users, there is a logger interface provided which can be used to create your own custom logger - see the below example.

Only the info, warn, error and debug methods are strictly required - beyond that, you can implement your own methods and styles too!

TypeScript

import { ILogger, LogLevel } from "rce.js";
import { inspect } from "util";

export default class MyCustomLogger implements ILogger {
    private level: LogLevel;
    
    public constructor(level: LogLevel) {
        this.level = level;
    }
    
    private format(content: any) {
        return typeof content === "string"
            ? content
            : inspect(content, { depth: 5 });
    }
    
    private has(level: LogLevel): boolean {
        return level >= this.level;
    }
    
    public debug(content: string) {
        if (!this.has(LogLevel.Debug)) return;
        
        console.log(`[DEBUG] ${this.format(content)}`);
    }
    
    public error(content: string) {
        if (!this.has(LogLevel.Error)) return;
        
        console.log(`[ERROR] ${this.format(content)}`);
    }
    
    public info(content: string) {
        if (!this.has(LogLevel.Info)) return;
        
        console.log(`[INFO] ${this.format(content)}`);
    }
    
    public warn(content: string) {
        if (!this.has(LogLevel.Warn)) return;
        
        console.log(`[WARN] ${this.format(content)}`);
    }
    
    // ...
}

After creating your custom logger class, you can set rce.js to use it like below!

TypeScript

import { RCEManager, LogLevel } from "rce.js";
import MyCustomLogger from "./logger";

const rce = new RCEManager({
    logger: {
        instance: new MyCustomLogger(LogLevel.Info)
    }
});
