fs: export constants from `fs/promises`
This pr re-export constants
from fs/promises
Motivation
see https://github.com/nodejs/node/issues/43140#issuecomment-1130087002
constants
is only export from fs
, but not export from fs/promises
.
When writing code that uses the promise based fs library via fs/promises
, if fs constants is used, we have to add another import module which is not convenient:
import fs from 'fs/promise';
import { constants } from 'fs';
If we re-export constants
from fs/promises
, then we could reduce two import to one:
import fs, { constants } from 'fs/promises';
