The Cloud Vision API allows developers to easily integrate vision detection features within applications, including image labeling, face and landmark detection, optical character recognition (OCR), and tagging of explicit content.
-
Set up authentication with a service account so you can access the API from your local workstation.
-
Install the client library:
npm install --save @google-cloud/vision -
Try an example:
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));
}Samples are in the samples/ directory. The samples' README.md
has instructions for running the samples.

The Vision API Node.js Client API Reference documentation also contains samples.
This library follows Semantic Versioning.
This library is considered to be in beta. This means it is expected to be mostly stable while we work toward a general availability release; however, complete stability is not guaranteed. We will address issues and requests against beta libraries with a high priority.
