v4.1.0

Breaking changes

  • interactive is no longer a function on the Wit client. Instead, you require it from the library. require('node-wit').interactive

v4.0.0

After a lot of internal dogfooding and bot building, we decided to change the API in a backwards-incompatible way. The changes are described below and aim to simplify user code and accommodate upcoming features.

We moved to a Promise-based API, instead of callbacks. This makes the code simpler and the error-handling more straight-forward. It's also inline with where JS is going with standards like fetch() and async/await that are based on Promises.

See ./examples to see how to use the new API.

Breaking changes

  • say renamed to send to reflect that it deals with more than just text
  • Removed built-in actions merge and error
  • Actions signature simplified with request and response arguments
  • Actions need to return promises and do not receive the cb parameter anymore
  • INFO level replaces LOG level
  • configuration is now done when instantiating the Wit object, instead of using env vars

v3.3.2

  • allows for overriding API version, by setting WIT_API_VERSION

v3.3.1

  • adding API versioning (defaults to 20160516)
  • warns instead of throwing when validating actions
  • fixing null values when cloning context

v3.3.0

  • callbacks are not called asynchronously by default, choice is left to the developer (use process.nextTick in your callback to emulate the previous behavior)
  • using node-fetch instead of requests
  • the message() API takes now an optional context as second parameter

v3.2.2

  • fixing context not updated in interactive mode
  • fixing array values in context
  • create readline interface only in interactive mode

v3.2.0

Unifying action parameters.

breaking

  • the say action now takes 4 parameters: sessionId, context, message, cb
  • the error action now takes 3 parameters: sessionId, context, error

v3.1.0

Updating action parameters.

breaking

  • the merge action now takes 5 parameters: sessionId, context, entities, message, cb
  • the error action now takes the context as second parameter
  • custom actions now take 3 parameters: sessionId, context, cb

v3.0.0

Bot Engine integration
