Get Your Front-end Rolling with Vue and InertiaJS

What to expect

  • An overview of cbInertia and Inertia.js
  • Why you would use this library
  • Example app to explore performance
  • Live coding some cbInertia views!

It will help if you are familiar with...

  • ColdBox Handlers and Routing
  • Vue Components and Templates

What is cbInertia?

Why am I learning about another JavaScript framework?

Today's Web Apps

  • Fast
  • Lightweight
  • Inertactive

Option #1

Multi-page Server-rendered App

Multi-page Server-rendered App

Cons

  • Full page refresh for each request
  • JavaScript feels bolted on

Pros

  • Codebase you are familiar with
  • Only one repository to configure routing, security, etc.

Option #2

Single Page App (SPA)

Single Page App (SPA)

Cons

  • Have to build an API
  • Client Side Auth and Routing
  • CORS

Pros

  • Fast (No page refreshes)
  • Interactive
  • Lightweight, Cacheable Payloads

Option #3

cbInertia & Inertia.js

cbInertia & Inertia.js

Pros

  • Single source of truth for routing, security, etc.
  • SPA-like Performance
  • No need for an API
  • Framework-agnostic

No, really, what is cbInertia?

  • Not a new framework, but the glue between frameworks
  • Build a SPA without the API
  • Use React, Vue, or Svelte as your View layer
  • cbInertia is the ColdBox server-side adapter for Inertia.js
  • Inertia.js was developed by Jonathan Reinink
  • There is an official server-side adapters for Laravel (PHP)
  • There are lots of community adapters (like ColdBox!)
  • There are official client-side adapters for React, Vue, and Svelte

Getting Started

Client-side Setup

Setup

npm install @inertiajs/vue3 vue
npm install --save-dev vite coldbox-vite-plugin @vitejs/plugin-vue

Setup

// vite.config.js

import { defineConfig } from "vite";
import coldbox from "coldbox-vite-plugin";
import vue from "@vitejs/plugin-vue";

export default () => {
    return defineConfig({
        plugins: [
            vue(),

// resources/assets/js/app.js

import { createApp, h } from "vue";
import { createInertiaApp } from "@inertiajs/vue3";
import { resolvePageComponent } from "coldbox-vite-plugin/inertia-helpers";

createInertiaApp({
    id: "app",
    title: title => `${title} | Quick Tailwind Inertia Template`,
    resolve: name =>
        resolvePageComponent(
            `./Pages/${name}.vue`,
            import.meta.glob("./Pages/**/*.vue")
        ),
    setup({ el, App, props, plugin }) {
        createApp({ render: () => h(App, props) })
            .use(plugin)
            .mount(el)
    }
});

Usage

Simple Render

// handlers/Dashboard.cfc
component {

    property name="cbInertia" inject="Inertia@cbInertia";

    function index( event, rc, prc ) {
        variables.cbInertia.render( "Dashboard/Index" );
    }

}

Vue Template

<!-- resources/assets/js/Pages/Dashboard/Index.vue -->

<template>

    property name="userService" inject="quickService:User";

    function index( event, rc, prc ) {
        variables.cbInertia.render( "Users/Index", {
            "users": variables.userService.asMemento().get()
        } );
