Cloud Natural Language API provides natural language understanding technologies to developers, including sentiment analysis, entity analysis, and syntax analysis. This API is part of the larger Cloud Machine Learning API family.
A comprehensive list of changes in each version may be found in the CHANGELOG.

npm install @google-cloud/language
async function quickstart() {
// Imports the Google Cloud client library
const language = require('@google-cloud/language');
// Instantiates a client
const client = new language.LanguageServiceClient();
// The text to analyze
const text = 'Hello, world!';
const document = {
content: text,
type: 'PLAIN_TEXT',
};
// Detects the sentiment of the text
const [result] = await client.analyzeSentiment({document: document});

Samples are in the samples/

The Natural Language Node.js Client API Reference documentation also contains samples.
Our client libraries follow the Node.js release schedule. Libraries are compatible with all current active and maintenance versions of Node.js.
Client libraries targeting some end-of-life versions of Node.js are available, and
can be installed via npm dist-tags.
The dist-tags follow the naming convention legacy-(version)
.
Legacy Node.js versions are supported as a best effort:
- Legacy versions will not be tested in continuous integration.
- Some security patches may not be able to be backported.
- Dependencies will not be kept up-to-date, and features will not be backported.
legacy-8
: install client libraries from this dist-tag for versions compatible with Node.js 8.
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.
