ACL / Roles + Permissions

https://github.com/djvirgen/virgen-acl Simple and elegant, create your own checks. No middleware?

https://github.com/OptimalBits/node_acl Use as middleware, create your own roles and access. Great choice.

https://github.com/tschaub/authorized Similar to connect roles... but a bit more robust? you can create roles and action, and associate many roles with that action

Installing the Postgres PostGIS extension on OSX

For reference: http://postgis.net/install

If you don’t already have PG installed

The most reliable way to get PostGIS on OSX is to download and install Postgres.app. Great for development and testing. Do not mix with other installations. Select the extension when prompted.

If you already have PG installed
