Bottender is built on top of Messaging APIs.

You can install Bottender globally to use the cli tools:

Examples

We have a bunch of examples in the examples folder. Here is the first one to get you started:

const { ConsoleBot } = require('bottender');  const bot = new ConsoleBot();  bot.onEvent(async context => {   await context.sendText('Hello World'); });  bot.createRuntime();

This will create and run a bot which always reply "Hello World" in the console.

You'll notice that there is an async function to be passed to the onEvent method, we call it handler. You can put your bot logic in there.
