Quickstart

Before you begin

1. Select or create a Cloud Platform project.
2. Enable billing for your project.
3. Enable the Generative Language API API.
4. Set up authentication so you can access the API from your local workstation.

Installing the client library

npm install @google-ai/generativelanguage

Using the client library

 * It will require modifications to work.
 * It may require correct/in-range values for request initialization.
 * TODO(developer): Uncomment these variables before running the sample.

 *  Required. The model name to use with the format name=models/{model}.

 *  Required. The free-form input text given to the model as a prompt.
 *  Given a prompt, the model will generate a TextCompletion response it
 *  predicts as the completion of the input text.

 *  attribute of the `Model` returned the `getModel` function.
 *  Values can range from 0.0,1.0,
 *  inclusive. A value closer to 1.0 will produce responses that are more
 *  varied and creative, while a value closer to 0.0 will typically result in

The Generative Language API Node.js Client API Reference documentation also contains samples.

Supported Node.js Versions

Our client libraries follow the Node.js release schedule. Libraries are compatible with all current active and maintenance versions of Node.js. If you are using an end-of-life version of Node.js, we recommend that you update as soon as possible to an actively supported LTS version.

Google's client libraries support legacy versions of Node.js runtimes on a best-efforts basis with the following warnings:

• Legacy versions are not tested in continuous integration.
• Some security patches and features cannot be backported.
• Dependencies cannot be kept up-to-date.

Client libraries targeting some end-of-life versions of Node.js are available, and can be installed through npm dist-tags. The dist-tags follow the naming convention legacy-(version). For example, npm install @google-ai/generativelanguage@legacy-8 installs client libraries for versions compatible with Node.js 8.

Versioning

This library follows Semantic Versioning.

This library is considered to be in preview. This means it is still a work-in-progress and under active development. Any release is subject to backwards-incompatible changes at any time.
