Web-based authentication support for Google services
npm install @langchain/google-webauthThis package contains resources to access Google AI/ML models
and other Google services. Authorization to these services use
either an API Key or service account credentials that are included
in an environment variable.
If you are running this on the Google Cloud Platform, or in a way
where service account credentials can be stored on a file system,
consider using the @langchain/google-gauth
package _instead_. You do not need to use both packages. See the
section on Authorization below.
``bash`
$ pnpm install @langchain/google-webauth
Authorization is either done through the use of an API Key, if it is
supported for the service you're using, or a Google Cloud Service
Account.
To handle service accounts, this package uses the google-auth-library
package, and you may wish to consult the documentation for that library
about how it does so. But in short, classes in this package will use
credentials from the first of the following that apply:
1. An API Key that is passed to the constructor using the apiKey attributeauthInfo
2. Credentials that are passed to the constructor using the attributeAPI_KEY
3. An API Key that is set in the environment variable
4. The Service Account credentials that are saved directly into the
