Compelete typescript definition for node's SystemError. A partial definition exists within TypeScript.

NodeSystemError.ts

/*
 Missing from TypeScript but documented by node.

 See https://nodejs.org/api/errors.html#class-systemerror
*/

interface NodeSystemError extends Error{
    address?: string; //If present, the address to which a network connection failed
    code:string;// The string error code
    dest:string;// If present, the file path destination when reporting a file system error
    errno:number;// The system-provided error number
    info?:Object;// If present, extra details about the error condition
    message:string;// A system-provided human-readable description of the error
    path?:string;// If present, the file path when reporting a file system error
    port?:number;// If present, the network connection port that is not available
    syscall:string;// The name of the system call that triggered the error
}

export type { NodeSystemError };

Extremely useful. Thank you!

I believe I eventual found some of this in the existing typescript files but nothing like this where it was all in one place.

You may want to use NodeJS.ErrnoException from @types/node, which is somewhat similar

I wrote this before discovering the official type which is preferable since it will be kept updated should node change. The official type does not currently include all documented attributes. However it should work for most use cases.
