Better error handling in Express with HttpException classes

httpExceptions.ts

export abstract class HttpException extends Error {
    status: number;
    constructor(status: number, message: string) {
        super(message);
        this.status = status;
        this.name = "HttpError";
    }
}

export class HttpBadRequestException extends HttpException {
    constructor(message = "Incorrect request") {
        super(400, message);
        this.name = "HttpBadRequestError";
    }
}

export class HttpUnauthorizedException extends HttpException {
    constructor(message = "Not authorized") {
        super(401, message);
        this.name = "HttpUnauthorizedError";
    }
}

export class HttpForbiddenException extends HttpException {
    constructor(message = "Forbidden") {
        super(403, message);
        this.name = "HttpForbiddenError";
    }
}

export class HttpNotFoundException extends HttpException {
    constructor(message = "Not found") {
        super(404, message);
        this.name = "HttpNotFoundError";
    }
}
