| // <div id="progress-container"></div> | |
| // If you want to put the progress inside the Vue instance (for example in the layout or below the Navbar) | |
| // you have to validate first that the element exists (#progress-container in this case). | |
| // Now you can use it here | |

| }, 2000) | |
| // Or in any view or component | |
| // this.$bar.start() | |
| // this.$bar.finish() | |
| // It can also be combined with navigation guards to automate the progress a little | |
