Handle CORS Client-side

Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources (e.g. fonts) on a web page to be requested from another domain outside the domain from which the first resource was served. This is set on the server-side and there is nothing you can do from the client-side to change that setting, that is up to the server/API. There are some ways to get around it tho.

Sources : MDN - HTTP Access Control | Wiki - CORS

CORS is set server-side by supplying each request with additional headers which allow requests to be requested outside of the own domain, for example to your localhost. This is primarily set by the header:

Access-Control-Allow-Origin

This effect system requires several of THREE.js's non-default post-processing and shader scripts.

UPDATE(10/9/2017): Check out aframe-effects; it's easier than what I've done here, and works in VR (which this Gist does not).

//**dataURL to blob**
function dataURLtoBlob(dataurl) {
    var arr = dataurl.split(','), mime = arr[0].match(/:(.*?);/)[1],
        bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n);
    while(n--){
        u8arr[n] = bstr.charCodeAt(n);
    }
    return new Blob([u8arr], {type:mime});
}

I really liked @tjvantoll article Handling Failed HTTP Responses With fetch(). The one thing I found annoying with it, though, is that response.statusText always returns the generic error message associated with the error code. Most APIs, however, will generally return some kind of useful, more human friendly message in the body.

Here's a modification that will capture this message. The key is that rather than throwing an error, you just throw the response and then process it in the catch block to extract the message in the body:

fetch("/api/foo")
  .then( response => {
    if (!response.ok) { throw response }
    return response.json()  //we only get here if there is no error
 })

function debounce(callback, wait, immediate = false) {
  let timeout = null 
  
  return function() {
    const callNow = immediate && !timeout
    const next = () => callback.apply(this, arguments)
    
    clearTimeout(timeout)
    timeout = setTimeout(next, wait)

Comparison of npm scripts vs Gulp

npm scripts

Pros

• npm scripts are low-level and leverage the actual library you want to use (example: "lint": "eslint ./")
• package.json is a central place to see what scripts are available (also npm run will list all scripts)
• When things get too complicated you can always defer to another file (example: "complex-script": "babel-node tools/complex-script.js")
• npm scripts are more powerful than one might first think (pre/post hooks, passing arguments, config variables, chaining, piping, etc...)

Guide on how to create and set up your Django project with webpack, npm and ReactJS :)

Hopefully this will answer "How do I setup or start a Django project?" I was trying to set up my own website, and there was a lot to read, learn and digest! Therefore, I put this together which is a collection of all the guides/blog posts/articles that I found the most useful. At the end of this, you will have your barebones Django app configured and ready to start building :)

NOTE: This guide was built using Django 1.9.5, NodeJS 4+ with NPM 3+
