Custom Logger

Todo: Change from the register method to decorators

Custom loggers can easily be created by extending the Base class

import { Base, HttpGroups, useCustomLogger } from '@sign-logger/express';
import { format, Colors, Backgrounds } from '@sign-logger/core';
import express, { Request, Response } from 'express';

class CustomLogger extends Base {
    onInformational(req: Request, res: Response) {
        console.log(format(`${req.method} ${req.originalUrl} INFORMATIONAL`).apply(Colors.WHITE, Backgrounds.BLUE));
    }

    onAnotherInformational(req: Request, res: Response) {
        console.log(format(`${req.method} ${req.originalUrl} another INFORMATIONAL`).apply(Colors.WHITE, Backgrounds.BLUE));
    }
}

const app = express();
const logger = new CustomLogger();
logger.register(HttpGroups.INFORMATIONAL, logger.onInformational, onAnotherInformational);


app.use(useCustomLogger(logger));

Base#register(group: HttpGroups, ...methods: Function[])

Used to register listeners for a specific HTTP group

enum HttpGroups

Used to define the HTTP group for the listeners

INFORMATIONAL (100 - 199)
SUCCESS (200 - 299)
REDIRECTION (300 - 399)
CLIENT_ERROR (400 - 499)
SERVER_ERROR (500 - 599)
