This client library makes it easy to create Actions for the Google Assistant and supports Dialogflow, Actions SDK (v2), and Smart Home fulfillment.
- Client Library GitHub repo
- Client Library reference docs
- Actions on Google docs
- Actions on Google samples
Install the library with either npm install actions-on-google
or yarn add actions-on-google
if you use yarn.
To support features under Developer Preview, the library has a special preview
branch which can be installed using the @preview
tag.
This is installed with either npm install actions-on-google@preview
or yarn add actions-on-google@preview
.
The preview
tag will be kept up to date with every new version of the library.
You can use the Developer Preview version to experience exciting new features that we’re still testing to make sure we have the best developer experience, and help us providing feedback on the API design and feature set.
The APIs offered in Developer Preview have not matured to General Availability yet, which means:
- You can’t publish Actions that use features in Developer Preview.
- The APIs are potentially subject to backwards incompatible changes.
