@botbuildercommunity/middleware-spell-check v1.0.1

Spell Check Middleware

The Spell Check Middleware offers Bot Framework middleware components for the Cognitive Services Bing Spell Check API. You will need an Azure account, as well as a Cognitive Services resource created on Azure. Take a look at the Bing Spell Check API documentation for details.

Installing

npm install @botbuildercommunity/middleware-spell-check --save

Usage

All middleware is created and use in the same way. For example, for spell check, import the SpellCheck class from the package, and add it to your bot adapter:

import { SpellCheck } from '@botbuildercommunity/middleware-spell-check';

adapter.use(new SpellCheck(YOUR_BING_SPELL_CHECK_KEY));

When used, the turnState on the TurnContext will have a property named suggestion which is the actual suggestion. Furthermore turnState will have a property token which is the phrase which has been classified by the service to be replaced by the suggestion. A full example can be seen in the sample bot test file.

Supported middleware classes include:

• SpellCheck

Each class takes the one required parameter like in the example usage above.

In each case, properties are added to the turnState of the TurnContext You can retrieve them in your bot via:

• context.turnState.get("token") //This is the token which you could replace by suggestion
• context.turnState.get("suggestion") //This is the suggestion which the token could be replaced with
