How to install

npm install nestjs-algolia
npm install --save-dev @types/algoliasearch

or

yarn add nestjs-algolia
yarn add -D @types/algoliasearch

How to use

Register the module

import { AlgoliaModule } from 'nestjs-algolia';

@Module({
  imports: [
    AlgoliaModule.register({
      applicationId: 'YOUR_APPLICATION_ID',
      apiKey: 'YOUR_API_KEY',
    }),
  ],
})
export class AppModule {}

Inject the service

import { AlgoliaService } from 'nestjs-algolia';

@Injectable()
export class AppService {
  constructor(private readonly algoliaService: AlgoliaService) {}

  addRecordToIndex(
    indexName: string,
    record: any,
  ): Promise<algoliasearch.Task> {
    const index = this.algoliaService.initIndex(indexName);

    return index.addObject(record);
  }
}

Async options

Quite often you might want to asynchronously pass your module options instead of passing them beforehand. In such case, use registerAsync() method, that provides a couple of various ways to deal with async data.

Use factory

AlgoliaModule.registerAsync({
  useFactory: () => ({
    applicationId: 'YOUR_APPLICATION_ID',
    apiKey: 'YOUR_API_KEY',
  }),
});

Obviously, our factory behaves like every other one (might be async and is able to inject dependencies through inject).

AlgoliaModule.registerAsync({
  imports: [ConfigModule],
  useFactory: async (configService: ConfigService) => ({
    applicationId: configService.getString('ALGOLIA_APPLICATION_ID'),
    apiKey: configService.getString('ALGOLIA_API_KEY'),
  }),
  inject: [ConfigService],
}),

Use class

AlgoliaModule.registerAsync({
  useClass: AlgoliaConfigService,
});

Above construction will instantiate AlgoliaConfigService inside AlgoliaModule and will leverage it to create options object.

class AlgoliaConfigService implements AlgoliaOptionsFactory {
  createAlgoliaOptions(): AlgoliaModuleOptions {
    return {
      applicationId: 'YOUR_APPLICATION_ID',
      apiKey: 'YOUR_API_KEY',
    };
  }
}

Use existing

AlgoliaModule.registerAsync({
  imports: [ConfigModule],
  useExisting: ConfigService,
}),

It works the same as useClass with one critical difference - AlgoliaModule will lookup imported modules to reuse already created ConfigService, instead of instantiating it on its own.
