Custom logger

Waylis outputs logs to the terminal and also has a built-in ability to save them to files.

By default, a simple built-in SimpleLogger is used:

import { SimpleLogger } from "@waylis/core";

const app = new AppServer({
    logger: new SimpleLogger({
        levels: ["error", "warn", "info", "debug"],
        logsDir: "logs",
        writeToFile: true,
    }),
});

If you wish, you can use your own logger, which must satisfy the Logger interface:

interface Logger {
    info(...args: unknown[]): void;
    warn(...args: unknown[]): void;
    error(...args: unknown[]): void;
    debug(...args: unknown[]): void;
}
