Summary
In this chapter, we experienced how to make a chatbot application with Slack, Watson, and Node-RED. This time, we used Slack as a chat platform, but you can use any chat platforms that have APIs, such as LINE, Microsoft Teams, and so on, instead of Slack.
This chapter is also very helpful for creating any applications that are not IoT-based. Node-RED can develop various applications by linking with any Web API.
In the next chapter, let's develop our own node. Of course, it can be used in any environment. Developing your own node with Node-RED means developing a new node that cannot be done with the existing nodes. This is surely the first step for advanced users of Node-RED.
