Cloud AutoML: Node.js Client

🔔AutoML API NodeJS Client is now available in Vertex AI. Please visitnode-js-aiplatformfor the new NodeJS Vertex AI client. Vertex AI is our next generation AI Platform, with many new features that are unavailable in the current platform.Migrate your resources to Vertex AI to get the latest machine learning features, simplify end-to-end journeys, and productionize models with MLOps.

Quickstart

Before you begin

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

Installing the client library

npm install @google-cloud/automl

Using the client library

const automl = require('@google-cloud/automl');const fs = require('fs');// Create client for prediction service.const client = new automl.PredictionServiceClient();/** * TODO(developer): Uncomment the following line before running the sample. */// const projectId = `The GCLOUD_PROJECT string, e.g. "my-gcloud-project"`;// const computeRegion = `region-name, e.g. "us-central1"`;// const modelId = `id of the model, e.g. “ICN723541179344731436”`;// const filePath = `local text file path of content to be classified, e.g. "./resources/flower.png"`;// const scoreThreshold = `value between 0.0 and 1.0, e.g. "0.5"`;// Get the full path of the model.const modelFullId = client.modelPath(projectId, computeRegion, modelId);// Read the file content for prediction.const content = fs.readFileSync(filePath, 'base64');const params = {};if (scoreThreshold) {  params.score_threshold = scoreThreshold;}// Set the payload by giving the content and type of the file.const payload = {};payload.image = {imageBytes: content};// params is additional domain-specific parameters.// currently there is no additional parameters supported.const [response] = await client.predict({  name: modelFullId,  payload: payload,  params: params,});console.log('Prediction results:');response.payload.forEach(result => {  console.log(`Predicted class name: ${resuresultplayName}`);  console.log(`Predicted class score: ${resuresultssification.score}`);});

Supported Node.js Versions

Our client libraries follow theNode.js release schedule.Libraries are compatible with all currentactive andmaintenance versions ofNode.js.If you are using an end-of-life version of Node.js, we recommend that you updateas soon as possible to an actively supported LTS version.

Google's client libraries support legacy versions of Node.js runtimes on abest-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, andcan be installed through npmdist-tags.The dist-tags follow the naming conventionlegacy-(version).For example,npm install @google-cloud/automl@legacy-8 installs client librariesfor versions compatible with Node.js 8.

Versioning

This library followsSemantic Versioning.

This library is considered to bestable. The code surface will not change in backwards-incompatible waysunless absolutely necessary (e.g. because of critical security issues) or withan extensive deprecation period. Issues and requests againststable librariesare addressed with the highest priority.
