How to serve a Gitbook on Heroku
Do not run the gitbook-cli directly on Heroku, gitbbok will use a lot of memory and pass the 512MB limit for a free dyno. The best way is to first build your book to a static website and then serve the static content with either nodejs with express static or with sinatra.
Run the following inside your gitbook folder.
gitbook buildA new folder will be created, _book and all your html files will be here. You can now create a new app on Heroku and serve your static content.
After you do gitbook build, you can serve that directory with Express by creating an app.js file like this:
var express = require('express'); var app = express();app.use(express.static(__dirname + '/_book'));app.listen(process.env.PORT || 3000);Dead-easy. For more information: Static files served by node.js on heroku - is it a good idea?
