Language Translator Node.js

The IBM Watson™ Language Translator service provides an Application Programming Interface (API) that lets you identify the language of text, and then use a custom business domain to translate the text from one supported language to another.
You can translate either by letting the service identify the source language or by selecting a source language and then by selecting a target language, and a business domain. Domain translation is linguistically targeted these business domains:

• The News domain - targeted at news articles and transcripts, it translates English to and from Arabic, Brazilian Portuguese, French, Italian, or Spanish. It also translates Spanish to and from French.
• The Conversational domain - targeted at conversational colloquialisms, it translates English to and from Arabic, Brazilian Portuguese, French, Italian, or Spanish.
• The Patent domain - targeted at technical and legal terminology, it translates Brazilian Portuguese, Chinese, or Spanish to English.

Getting started

1. You need an IBM Cloud account. If you don't have one, sign up. Experimental Watson Services are free to use.

2. Download and install the Cloud-foundry CLI tool if you haven't already.

3. Edit the manifest.yml file and change <application-name> to something unique. The name you use determines the URL of your application. For example, <application-name>.mybluemix.net.

   applications:
   - services:
     - language-translator-service
     name: <application-name>
     command: node app.js
     path: .
     memory: 128M

4. Connect to IBM Clod with the command line tool.

cf api https://api.ng.bluemix.net
cf login

1. Create the Language Translator service in the IBM Cloud.

   cf create-service language_translator lite language-translator-service
   cf create-service-key language-translator-service myKey
   cf service-key language-translator-service myKey

2. Create a .env file in the root directory by copying the sample .env.example file using the following command:

cp .env.example .env

You will update the .env with the information you retrieved in steps 5.

The .env file will look something like the following:

LANGUAGE_TRANSLATOR_USERNAME=<username>
LANGUAGE_TRANSLATOR_PASSWORD=<password>
LANGUAGE_TRANSLATOR_URL=<url>

1. Install the dependencies you application need:

npm install

1. Start the application locally:

npm start

1. Point your browser to http://localhost:3000.

2. Optional: Push the application to IBM Cloud:

cf push

After completing the steps above, you are ready to test your application. Start a browser and enter the URL of your application.

        <your application name>.mybluemix.net
