WARNING: Should not be used for commercial purposed. If you really want, please use the Azure Service.

An easy way to get the translator service from Bing.

Getting Started

Install

$ npm install bing-translate-service

Usage

// For typescript
import { BingTranslator } from "bing-translator-service";

// create an instance of translator from 'en' to 'zh-Hans'. 
const translator = await BingTranslator.createTranslator("en", "zh-Hans");
translator.translate("Hello world")
    .then(data => {
      console.log(JSON.stringify(data, null, 2));
    })
    .catch(err => {
      console.log(err);
    });

// For javascript
import BingTranslator from "bing-translator-service";

// create an instance of translator from 'auto-detect' to 'zh-Hans'. 
const translator = await BingTranslator.createTranslator("auto", "zh-Hans");
// don't use the default translation rule and use a given one.
translator.translate("Hello world", "en", "zh-Hans")
    .then(data => {
      console.log(JSON.stringify(data, null, 2));
    })
    .catch(err => {
      console.log(err);
    });

Result

{
  "detectedLanguage": {
    "language": "en",
    "score": 1
  },
  "translations": [
    {
      "text": "世界您好",
      "transliteration": {
        "text": "shìjiè nínhǎo",
        "script": "Latn"
      },
      "to": "zh-Hans",
      "sentLen": {
        "srcSentLen": [
          11
        ],
        "transSentLen": [
          4
        ]
      }
    }
  ]
}

Why do this

Although bing-translate-api has already provided a simple way to help using bing translate service, during using it, I found some more features are needed:

• Hot start, to increase the startup speed.
• More information from response.

So,

• I write a cache to save status, which not only reduces impact on bing service, but also starts service quickly.
• Pass out the complete result of the bing service.

API

export interface TranslationResult {
  detectedLanguage: DetectedLanguage
  translations: Translation[]
}

export interface DetectedLanguage {
  language: string
  score: number
}

export interface Translation {
  text: string
  transliteration?: Transliteration
  to: string
  sentLen: SentLen
}

export interface Transliteration {
  text: string
  script: string
}

export interface SentLen {
  srcSentLen: number[]
  transSentLen: number[]
}

export class BingTranslator {
    static createTranslator(fromLang: string, toLang: string): Promise<BingTranslator>;
    static enableLog(): void;
    static disableLog(): void;
    static isLanguageSupported(lang: string): boolean;
    translate(text: string, fromLang: string, toLang: string): Promise<TranslationResult>;
}

Supported languages could be found here: lang.json.
