What I learned

The major learnings in this project is Vue Router. I not only know how to use router to navigate a declarative location but I understand how to use router's instance methods which can programmatically link to nested the routes.

Also, I confronted a problem on navigating between views. I found the URL was changed, while the page was not loaded. Fortunately, I found the solution is to add a key prop to router-view (see below for the example) to force load.

<router-view :key="$route.path"/>

Useful resources

• Stackoverflow - This helped me to avoid redundant navigation on Vue Router. See the code in Component-Header.

• Common Vue problems - This helpmed me to solve the problem that vue router doesn't reload when navigating between Cards.
