Quickstart
Before you begin
- Select or create a Cloud Platform project.
- Enable billing for your project.
- Enable the Google Cloud Vision API API.
- Set up authentication with a service account so you can access the
API from your local workstation.
Installing the client library
npm install @google-cloud/vision
Using the client library
async function quickstart() {
// Imports the Google Cloud client library
const vision = require('@google-cloud/vision');
// Creates a client
const client = new vision.ImageAnnotatorClient();
// Performs label detection on the image file
const [result] = await client.labelDetection('./resources/wakeupcat.jpg');
const labels = result.labelAnnotations;
console.log('Labels:');
labels.forEach(label => console.log(label.description));
}

Versioning
This library follows Semantic Versioning.
This library is considered to be General Availability (GA). This means it
is stable; the code surface will not change in backwards-incompatible ways
unless absolutely necessary (e.g. because of critical security issues) or with
an extensive deprecation period. Issues and requests against GA libraries
are addressed with the highest priority.
