Use this extension to perform natural language processing (NLP) tasks on strings (for example, reviews) written to a Cloud Firestore collection. The tasks available are sentiment analysis, entity extraction and text classification.
This extension listens to your specified Cloud Firestore collection. If you add a string to a specified field in any document within that collection, this extension:
- Performs the configured NLP tasks using the input string.
- Adds the NLP data of the string to a separate specified field in the same document.
You specify the desired NLP tasks at configuration time. All tasks are powered by the Google Cloud Natural Language API. The options offered are:
- Sentiment analysis.
- Entity extraction. Additional customization is available for this task. You can specify the types of entities to save (for example,
LOCATION,PERSON) and specify if the extension should save common noun entities. - Text classification.
If the original input field of the document is updated, then the NLP data will be automatically updated, as well.
Before installing this extension, make sure that you've set up a Cloud Firestore database in your Firebase project.
This extension uses other Firebase or Google Cloud Platform services which may have associated charges:
- Cloud Natural Language API
- Cloud Firestore

When you use Firebase Extensions, you're only charged for the underlying resources that you use. A paid-tier billing plan is only required if the extension uses a service that requires a paid-tier plan, for example calling to a Google Cloud Platform API or making outbound network requests to non-Google services. All Firebase services offer a free tier of usage. Learn more about Firebase billing.
