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

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

The Go language for experienced programmers

Why use Go?

• Like C, but with garbage collection, memory safety, and special mechanisms for concurrency
• Pointers but no pointer arithmetic
• No header files
• Simple, clean syntax
• Very fast native compilation (about as quick to edit code and restart as a dynamic language)
• Easy-to-distribute executables

How to update the Go version

System: Debian/Ubuntu/Fedora. Might work for others as well.

1. Uninstall the exisiting version

As mentioned here, to update a go version you will first need to uninstall the original version.

To uninstall, delete the /usr/local/go directory by:
