Add Serving Static Files to Documentation

[cama]

Background history

This happens when Facebook sends messages that BotStackJS not yet able to handle correctly. Typically, this is a service message from facebook. In the future we will properly handle.

This is inside the Class BotStack:
this.server.get('/images/', (req, res, next) => {
//res.send(__dirname + '/images')
let serveData = {
directory: './images', -------- I cannot understand where is
the root for this restify function and it just won't serve an html from a
subfolder. I tried for 2 hours different debugging things and couldn't find
it...
file: 'images.html',
}
restify.serveStatic(serveData),
});
Under the hood BotStackJS uses Restify, perhaps you should read the documentation on restify.serveStatic

Usually the root directory is the directory where you run node for execution.

BotStackJS can serve static files for you. All you just need to set 2 environment variables: BOTSTACK_STATIC and BOTSTACK_URL.

For example, you can set this value: BOTSTACK_STATIC=./media
And next create public path inside media (it's Restify issue). After this you can get your files by this URL for example : http://localhost:3000/public/myfile.png

BOTSTACK_URL reserved for future use. You can setup this variable with empty value: BOTSTACK_URL=
