hosting spa on github pages

### Notes on client-side routing:
### GitHub Pages doesn’t support routers that use the HTML5 `pushState` history API under the hood 
### (for example, React Router using `browserHistory`). 
### This is because when there is a fresh page load for a url like `http://user.github.io/todomvc/todos/42`, 
### where `/todos/42` is a frontend route, 
### the GitHub Pages server returns 404 because it knows nothing of `/todos/42`. 
### If you want to add a router to a project hosted on GitHub Pages, 
### here are a couple of solutions:* 
### You could switch from using HTML5 history API to routing with hashes. 
### If you use React Router, you can switch to `hashHistory` for this effect, 
### but the URL will be longer and more verbose 
### (for example, `http://user.github.io/todomvc/#/todos/42?_k=yknaj`). 
### [Read more](https://reacttraining.com/react-router/web/api/Router) about different history implementations in React Router.* 
### Alternatively, you can use a trick to teach GitHub Pages to handle 404 by redirecting 
### to your `index.html` page with a special redirect parameter. 
### You would need to add a `404.html` file with the redirection code to the `build` folder before deploying 
### your project, and you’ll need to add code handling the redirect parameter to `index.html`. 
### You can find a detailed explanation of this technique [in this guide](https://github.com/rafrex/spa-github-pages).

### extra note from me: If you still can't get anything to render except the homepage even after giving the "exact" param
### then try moving your homepage router to the end of the switch tag
### that way it'll be checked at the very last for matching the url
