We are planning on building a Node.js service. Here's our evaluation of the current ORM landscape:

Last updated: May 2 2016

• Objection.js
  • http://vincit.github.io/objection.js/#introduction
  • Bad: API is Promise based and bulky. This means people can forget to have an error handler due to not being error first
    • http://vincit.github.io/objection.js/#getting-started
  • Good: Uses JSON schema for validation; this means content should be relatively reusable between server/browser

Debugging Node.js web applications running on Heroku using ngrok

Introduction

Heroku only allows each dyno to send and receive external network traffic on a single port, which means you can't simply run node --debug server.js and attach your debugger to your-app.herokuapp.com:5858.

To work around this, you can use ngrok and Heroku ngrok Buildpack to tunnel to the debugger's port and access it externally.

import { h, Component } from 'preact';


/** Creates a new store, which is a tiny evented state container.
 *  @example
 *    let store = createStore();
 *    store.subscribe( state => console.log(state) );
 *    store.setState({ a: 'b' });   // logs { a: 'b' }
 *    store.setState({ c: 'd' });   // logs { c: 'd' }

About this gist

With this gist I wanted to freeze some concepts about BackboneJS that could
save some time in the future either to me if I needed to use this functionality
again, or to somebody else.

This implementation addresses the need to retrieve some data from an API and
to populate a BackboneJS collection accordingly, storing the retrieved items 
as Models inside the Collection.
If you want to see this functionality built into an application, have a look

I've been deceiving you all. I had you believe that Svelte was a UI framework — unlike React and Vue etc, because it shifts work out of the client and into the compiler, but a framework nonetheless.

But that's not exactly accurate. In my defense, I didn't realise it myself until very recently. But with Svelte 3 around the corner, it's time to come clean about what Svelte really is.

Svelte is a language.

Specifically, Svelte is an attempt to answer a question that many people have asked, and a few have answered: what would it look like if we had a language for describing reactive user interfaces?

A few projects that have answered this question:

const useThunk = (reducer, initState) => {
  const [state, dispatch] = useReducer(reducer, initState);
  const thunkDispatch = action => {
    if (typeof action === "function") {
      action(dispatch, () => state);
    } else {
      dispatch(action);
    }
  };
  return [state, thunkDispatch];

Boolean() or !! (double bang, double negation)?

What's the best way to answer the question "true or false?" in JavaScript

JavaScript does not bother you too much with types (at first), which is both a blessing and a cure. But we all know the Boolean type. Boolean variables can either be true or false. Yes or no.

Every value in JavaScript can be translated into a boolean, true or false. Values that translate to true are truthy, values that translate to false are falsy. Simple.

This is about two ways to make that translation.
