Create a private fork of a public repository

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

  1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

How I migrated from ReactRouter v2 to v4

First couple things I thought about when migrating after reading the docs

So migrating my existing app wasn't as troublesome as I originally thought. First thing I did was take a look at my router and routes and figure try to make a mental model of all the files where I had nested routes in the existing app because those components/containers will contain {this.props.children}. So I need to replace those with the nested <Match /> components.

So just to give an example:

In v2:

<Router history={history}>
  <Route path="/" component={App}>

Drop-in replacement for React Router <Link> that works with React Redux optimizations (https://github.com/reactjs/react-router/issues/470)
// While I claim this is a drop-in replacement, it is a little bit slower.
// If you have hundreds of links, you might spend a few more milliseconds rendering the page on transitions.
// KNOWN ISSUES WITH THIS APPROACH:
// * This doesn't work great if you animate route changes with <TransitionGroup>
// because the links are going to get updated immediately during the animation.
// * This might still not update the <Link> correctly for async routes,
// as explained in https://github.com/reactjs/react-router/issues/470#issuecomment-217010985.
