• JavaScript Standard Style
• Are Semicolons Necessary in JavaScript? (8’ background explanation)

The Vue.js community favors omitting optional semicolons ; in Javascript.

Axios HTTP Library

• Documentation with Examples

Bootstrap 4 and BootstrapVue

• BootstrapVue Components
  • Layout and Grid System
  • Link
  • Button
  • Form
• BootstrapVue Online Playground

Plain Bootstrap 4 uses a popular JS library called jQuery for dynamic components (e.g., dropdowns). However, using jQuery with Vue is problematic and therefore we use BootstrapVue here.

Debug in VSCode with Chrome

1. [VSCode] Set a breakpoint in your Javascript code
2. [Terminal] Run npm run serve to serve the client
3. [VSCode] Select Debug > Start Debugging (F5) to automatically start a debug session in Chrome¹
4. [Chrome] Browse in Chrome to trigger your breakpoint and the focus will jump back to VSCode

Find illustrated instructions in the Vuejs Debug Docs.

¹ Chrome will launch with a separate user profile (not to mess up with your familiar daily Chrome profile) in a temp folder as described in the VSCode Debugger for Chrome. It is recommended to install the vue-devtools Chrome Extension there.
