38 | ## Quickstart
|
39 |
|
40 | ### Before you begin
|
41 |
|
42 | 1. [Select or create a Cloud Platform project][projects].
|
43 | 1. [Enable billing for your project][billing].
|
44 | 1. [Enable the Google Cloud Vision API API][enable_api].
|
45 | 1. [Set up authentication with a service account][auth] so you can access the
|
46 | API from your local workstation.
|
47 |
|
48 | ### Installing the client library
|
49 |
|
50 | ```bash
|
51 | npm install @google-cloud/vision
|
52 | ```
|
53 |
|
54 |
|
55 | ### Using the client library
|
56 |
|
57 | ```javascript
|
58 | async function quickstart() {
|
59 | // Imports the Google Cloud client library
|
60 | const vision = require('@google-cloud/vision');
|
61 |
|
62 | // Creates a client
|
63 | const client = new vision.ImageAnnotatorClient();
|
64 |
|
65 | // Performs label detection on the image file
|
66 | const [result] = await client.labelDetection('./resources/wakeupcat.jpg');
|
67 | const labels = result.labelAnnotations;
|
68 | console.log('Labels:');
|
69 | labels.forEach(label => console.log(label.description));
|
70 | }
|
71 |
|
72 | ```
