Quick Setup Using JSPM

Cross post from my employer's development blog:

Want to use JSPM rather than Bower for running the example? Follow these steps. This is basically a duplicate of the [Getting Started tutorial][tutorial] on the [ website][website] but using a really simple JSPM setup. This is a very crude guide where I list everything I had to do to get things running.

Create an empty project folder
npm install
Copy server code verbatim from the Getting Started guide
jspm install
Hit enter for all the prompts from JSPM

We’re going to modify the client side code a little bit. We have native support for ES6 compiling with JSPM/Babel so we can import the Deepstream client directly:

import deepstream from '';
let ds = deepstream( 'localhost:6020' ).login();

let record = ds.record.getRecord( 'someUser' );

let input = document.querySelector( 'input' );

input.onkeyup = function(){
   record.set( 'firstname', input.value );

record.subscribe( 'firstname', function( value ){
   input.value = value;

Save as index.js

Run `jspm bundle index.js index-bundle.js`

If you have an error about ‘yeast’ missing, run `jspm install npm:yeast`

For the HTML, we’re going to move all the JS into the body so that the `input` exists before we try to find it. Note JSPM requires a couple extra files, which should already be ready to go.


Run `node start.js` and open your index.html page in two browsers, you should now see the input’s staying in sync!

Again, this is a pretty crude “up and running” proof of concept. You’ll have to manually run JSPM’s `bundle` command for any client side changes. Ideally you’ll want a little more automated of an asset pipeline at some point.

Changing Password Requirements with SailsJS and Passport

Cross post from my employer's development blog:

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…
