    npm-version npm-installs dev-deps issues Node.js CI


    Unofficial SDK for Microsoft® Cognitive Services written for Node.JS.

    Usage of Microsoft® Cognitive Services is bound by their Terms and Conditions.

    Getting Started

    To get started first sign up and grab your API keys. Then figure out which API you want to use, you can find descriptions here.

    To use this SDK in your project, run npm install --save cognitive-services.

    Then make a JS file in your project directory and add the following:

    const cognitiveServices = require('cognitive-services');

    You are now ready to use the APIs, for example:

    const parameters = {
        "mode": "proof",
        "mkt": "en-us"
    const body = "Text=Bill+Gatas"
    const spellCheckClient = new cognitiveServices.bingSpellCheck({
        apiKey: "YOUR-API-KEY",
        endpoint: "YOUR-ENDPOINT"
    }).then(response => {

    If you want to see more examples of use you can see within the test folder.


    PRs are welcome! If you want to contribute, follow these steps:

    1. You need to have Node >= 10.0.0. (Tip: use nvm!)
    2. Download the source code and run npm install.
    3. Update the file tests/config.js with your own API keys.
    4. Run npm test.

    NOTE: if you want to run the tests in just one class, change describe to describe.only and run npm test.
