Symlink for static files

Among applying the changes in the other files in this gist, you need to symlink the directory you are serving the app with in the root app's public directory so that NGINX can serve the static files in the sub-app.

For example, if you have an app at /home/coffeencoke/apps/app.coffeencoke.com/current/public as your root app, and you have the sub app served at http://app.coffeencoke.com/admin, then you need to symlink /home/coffeencoke/apps/admin-app.coffeencoke.com/current/public to /home/coffeencoke/apps/app.coffeencoke.com/current/public/admin like so:

ln -s /home/coffeencoke/apps/admin-app.coffeencoke.com/current/public /home/coffeencoke/apps/app.coffeencoke.com/current/public/admin

JedWatson

This is an example of how to scaffold API endpoints to list / get / create / update / delete Posts in a Keystone website.

It's a modification of the default project created with the yo keystone generator (see https://github.com/JedWatson/generator-keystone)

Gists don't let you specify full paths, so in the project structure the files would be:

routes-index.js        -->    /routes/index.js         // modified to add the api endpoints
routes-api-posts.js    -->    /routes/api/posts.js     // new file containing the Post API route controllers
