    Cloud Media Translation: Node.js Client

    release level npm version codecov

    Mediatranslation client for Node.js

    A comprehensive list of changes in each version may be found in the CHANGELOG.

    Read more about the client libraries for Cloud APIs, including the older Google APIs Client Libraries, in Client Libraries Explained.

    Quickstart

    Before you begin

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

    Installing the client library

    npm install @google-cloud/media-translation

    Using the client library

    const fs = require('fs');
    
    // Imports the CLoud Media Translation client library
    const {
      SpeechTranslationServiceClient,
    } = require('@google-cloud/media-translation');
    
    // Creates a client
    const client = new SpeechTranslationServiceClient();
    
    async function quickstart() {
      /**
       * TODO(developer): Uncomment the following lines before running the sample.
       */
      // const filename = 'Local path to audio file, e.g. /path/to/audio.raw';
      // const encoding = 'Encoding of the audio file, e.g. LINEAR16';
      // const sourceLanguage = 'BCP-47 source language code, e.g. en-US';
      // const targetLangauge = 'BCP-47 target language code, e.g. es-ES';
    
      const config = {
        audioConfig: {
          audioEncoding: encoding,
          sourceLanguageCode: sourceLanguage,
          targetLanguageCode: targetLanguage,
        },
      };
    
      // First request needs to have only a streaming config, no data.
      const initialRequest = {
        streamingConfig: config,
        audioContent: null,
      };
    
      const readStream = fs.createReadStream(filename, {
        highWaterMark: 4096,
        encoding: 'base64',
      });
    
      const chunks = [];
      readStream
        .on('data', chunk => {
          const request = {
            streamingConfig: config,
            audioContent: chunk.toString(),
          };
          chunks.push(request);
        })
        .on('close', () => {
          // Config-only request should be first in stream of requests
          stream.write(initialRequest);
          for (let i = 0; i < chunks.length; i++) {
            stream.write(chunks[i]);
          }
          stream.end();
        });
    
      const stream = client.streamingTranslateSpeech().on('data', response => {
        const {result} = response;
        if (result.textTranslationResult.isFinal) {
          console.log(
            `\nFinal translation: ${result.textTranslationResult.translation}`
          );
          console.log(`Final recognition result: ${result.recognitionResult}`);
        } else {
          console.log(
            `\nPartial translation: ${result.textTranslationResult.translation}`
          );
          console.log(`Partial recognition result: ${result.recognitionResult}`);
        }
      });
    

    Samples

    Samples are in the samples/ directory. Each sample's README.md has instructions for running its sample.

    Supported Node.js Versions

    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 tags available

    • legacy-8: install client libraries from this dist-tag for versions compatible with Node.js 8.

    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.
