Interface SystemError

Interface for Node.js System errors

Node.js generates system errors when exceptions occur within its runtime environment. These usually occur when an application violates an operating system constraint. For example, a system error will occur if an application attempts to read a file that does not exist.

interface SystemError {
    address?: string;
    code: string;
    dest?: string;
    errno: string | number;
    info?: unknown;
    message: string;
    name: string;
    path?: string;
    port?: string;
    stack?: string;
    syscall: string;
}
