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.

Using the client library

1. Select or create a Cloud Platform project.

2. Enable billing for your project.

3. Enable the Google Cloud Vision API API.

4. Set up authentication with a service account so you can access the API from your local workstation.

5. Install the client library:

    npm install --save @google-cloud/vision
   

6. 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

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.

Versioning

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.
