zone.js/node breaks for fs.realpath.native and fs.realpathSync.native

[lamweili]

Which @angular/* package(s) are the source of the bug?

Don't known / other

Is this a regression?

No

Description

1. Using the ready-made https://angular.io/generated/zips/universal/universal.zip from https://angular.io/guide/universal.

2. Edited server.ts or the TypeScript would whine (TS4111) and refuse to run.

   -  const port = process.env.PORT || 4000;
   +  const port = process.env['PORT'] || 4000;

3. I added the following at the very beginning of the server.ts:

   +  console.log("NODEJS VERSION:", process.version);
   
   +  console.log("=====1=====");
   +  import * as fs from 'fs';
   +  console.log("2nd-level API fs.appendFile:", fs.appendFile); // a second-level API (fs.xxx)
   +  console.log("2nd-level API fs.realpath:", fs.realpath);
   +  console.log("3rd-level API fs.realpath.native:", fs.realpath.native); // a third-level API (fs.xxx.yyy)
   
   =  import 'zone.js/node';
   
   +  console.log("=====2=====");
   +  console.log("2nd-level API fs.appendFile:", fs.appendFile); // a second-level API (fs.xxx)
   +  console.log("2nd-level API fs.realpath:", fs.realpath);
   +  console.log("3rd-level API fs.realpath.native:", fs.realpath.native); // a third-level API (fs.xxx.yyy)
   
   =  import { ngExpressEngine } from '@nguniversal/express-engine';

4. npm install followed by npm run dev:ssr command.

5. It seems like the import 'zone.js/node'; did something to the fs.
   fs.realpath.native become undefined from the logs.

   

6. It does seem like zone.js/node did not factor in fs third-level functions. From the fs API documentation, most are second-level functions (i.e. fs.xxx). But there are 2 exceptions since NodeJS 9.2.0 that are in third-level (i.e. fs.xxx.yyy), which are fs.realpath.native and fs.realpathSync.native. So when the package did some wrapping around, the third-level functions broke.

Please provide a link to a minimal reproduction of the bug
