Changing Password Requirements with SailsJS and Passport

Cross post from my employer's development blog: http://rootinc.github.io/2016/03/16/pass-requirements-sails/

If you perform an installation of [Passport][passport] with [SailsJS][sails] using the [Sails Passport Auth Generator][sails-generate-auth] you get several files in your app already configured for you. If you then use passport-local, you will already have a complexity requirement on the password. It defaults to requiring 8 characters minimum, letters, numbers, and symbols.

What if you want to change this requirement? In the generated model file `Passport.js`, you should see a line that says `provider   : { type: 'alphanumericdashed' },` and `password    : { type: 'string', minLength: 6 }`. The minLength is an easy and obvious change. What about the complexity requirement though? This stumped me for a bit. There doesn’t seem to be any mention of these keywords or providers on the Passport official site, nor anything in the [Passport-local repository][passport…

Moving to Babel 6 on the Server

Cross post from my employer's development blog: http://rootinc.github.io/2016/03/14/babel-6-server/

Decided it was time to upgrade my server-side code to run on Babel 6. Below is a synopsis of all the issues I ran into and resolved while upgrading my 0.11.3 SailsJS server to run with Babel 6 transpilation.

The upgrade to Babel 6 itself is easily achieved in Sails by upgrading the `sails-hook-babel` package.

### Missing preset
`couldn't find preset "stage-0" relative to directory`
Just because a preset is on the official Babel preset page, doesn’t mean that Babel comes with it. Simple fix by installing the [package][1] from npm. Read more [here][2].

### Need strict mode everywhere
`Block-scoped declarations (let, const, function, class) not yet supported outside strict mode`
I didn’t have to worry about this before, and I don’t feel like …

IE Caches a Lot

Cross post from my employer's development blog: http://rootinc.github.io/2016/03/09/ie-caches/

In developing a page, I decided to do things a bit differently on the server. By doing an explicit check on the HTTP request headers, I can detect server-side if a request to the server is coming via XHR (Ajax) or a standard page load. I can then serve different content based on the request type. So, I can use the same URL for retrieving the initial HTML page and the raw JSON data associated with that page. Express makes this pretty easy:
if (req.xhr){      return res.json(await this.usersData());    }    else {      return res.view('users', await this.usersData());    }
I’m not sure if it’s technically more RESTful than having separate URL routes for data and HTML, but it felt like it made sense. The URL is referring to the same data, and based on a header, I want to determine how it is represented, but the data doesn’t change so why should the URL? This also makes it possible to d…
