NodeJS N PACKAGE ISSUES

sudo chown -R $(whoami) /usr/local/n
# we may need to run this
# sudo chown -R $(whoami) /usr/local/lib/node_modules/

We may need to run this

sudo chown -R $(whoami) /usr/local/bin/npm
sudo chown -R $(whoami) /usr/local/bin/node
sudo chown -R $(whoami) /usr/local/bin/npx

This seemed to be good solution

# make cache folder (if missing) and take ownership
sudo mkdir -p /usr/local/n
sudo chown -R $(whoami) /usr/local/n
# take ownership of node install destination folders
sudo chown -R $(whoami) /usr/local/bin /usr/local/lib /usr/local/include /usr/local/share
# no longer need sudo as you own the folders
n lts

What the point of using RegExp here?
Express patterns is simpler, yet almost as powerful as regular expressions:

app.get('/blog(?:/p/:page([0-9]+)?)?', blog.list);

This route will match all of the following urls:

/blog
/blog/
/blog/p
/blog/p/
/blog/p/123

In blog.list controller req.params.page will contain page number or will be undefined if it wasn't supplied.
