Hello! Thank you for the project. So I am having this error that I would guess is related to the last update of Nest. Any idea?

Hi Paul,

I've prepared an update to the library to support nestjs 6. As I don't have the time to migrate one of my application yet, can I ask you to test if the changes I've made are working for you?

Here's how you can proceed:

• checkout the v2 branch to a temporary directory

cd ~/temp
git clone https://github.com/fvilers/nestjs-algolia.git
cd nestjs-algolia
git checkout v2.0.0

• build the v2:

npm install
npm run build

• make this build available locally:

cd dist
npm link

• use it in your project

cd ~/your-project
npm uninstall nestjs-algolia
npm link nestjs-algolia

If everything works great, I'll publish the package on npm and you will be able to use it from there.

• remove local link:

cd ~/your-project
npm unlink nestjs-algolia
cd ~/temp/nestjs-algolia/dist
npm unlink

Hi,

Thank you very much for the fix and sorry for the delay.

We are getting this error:

Nest can't resolve dependencies of the AlgoliaService (?). Please make sure that the argument ALGOLIA_MODULE_OPTIONS at index [0] is available in the SearchIndexModule context.

Potential solutions:
- If ALGOLIA_MODULE_OPTIONS is a provider, is it part of the current SearchIndexModule?
- If ALGOLIA_MODULE_OPTIONS is exported from a separate @Module, is that module imported within SearchIndexModule?
  @Module({
    imports: [ /* the Module containing ALGOLIA_MODULE_OPTIONS */ ]
  })

The fix for this is to export the ALGOLIA_MODULE_OPTIONS in the algolia.module.ts, then it's working perfectly:

@Module({
  providers: [AlgoliaService],
  exports: [ALGOLIA_MODULE_OPTIONS, AlgoliaService],
})

Are you happy with this change? If so I can cook a PR on your v2 version.

Thanks again!

Hi, sorry for the late response. I added the ALGOLIA_MODULE_OPTIONS to the export array. Could you give a try again?

Thanks in advance!
