Current behavior

When running in production SSR mode, ngx-cache fails on second load. It looks like it tries to create the .cache folder twice, and fails:

Error: EEXIST: file already exists, mkdir '/Users/foo/bar/.cache'
    at Object.fs.mkdirSync (fs.js:874:3)
    at new FsStorageService (/Users/foo/bar/node_modules/@ngx-cache/fs-storage/bundles/ngx-cache-fs-storage.umd.js:131:20)
    at _createClass (/Users/foo/bar/node_modules/@angular/core/bundles/core.umd.js:20740:24)
    at _createProviderInstance (/Users/foo/bar/node_modules/@angular/core/bundles/core.umd.js:20712:30)

    at resolveNgModuleDep (/Users/foo/bar/node_modules/@angular/core/bundles/core.umd.js:20676:25)

Expected/desired behavior

The expectation is that the cache services should check to see if the folder exists before trying to recreate it. This error breaks everything and shows in the browser.

Minimal reproduction of the problem with instructions

1. Checkout the latest ng-seed/universal.
2. Use npm run start:ssr:prod to start on localhost:4000

has anybody figured out how to fix/workaround this?

I am facing the same issue, any ideas what is happening?

Hi, same problem here, some hint to resolve ?

[meatfly]

there is bug in XpFsStorageService use if (!stat.isDirectory()) { not
if (!stat.hasOwnProperty('isDirectory')) {

workaround can by done by own implementation of storageService
https://gist.github.com/meatfly/baff02d8004802a870b77171f0b3f6e0

and than use in app.server.module.ts

   ServerCacheModule.forRoot([
      {
        provide: CACHE,
        useClass: FsCacheService
      },
      {
        provide: STORAGE,
        useClass: XpFsStorageService
