I'm trying to connect my web client (written in Reactjs) to DialogFlow. I tried using the soon to be defunct javascript api. When I tried to import `ApiAiClient` into my project, the website failed to render, saying that there was no such class in the library I was attempting to import it from, which was `api-ai-javascript`. Is there any way to connect the web client directly to DialogFlow? I noticed the V2 libraries include node.js, but importing the node.js library that doesn't seem to work. I'm aware that connecting my client to firebase would enable me to use cloud functions and that's what I could use to connect my web client to dialogflow but I'm trying to set this thing up as cheaply as possible and cloud functions would only be another expense.
