A CodeIgniter 4 Skeleton Application with Vue.js integration.

• SPA application with Vue Router with cached pages after visited.
• Using server side template from CodeIgniter 4, compiled with Vue.compile() in Vue.js component's render().
• Using Vuex for state management library, combo with sessionStorage on portfolio page.
• Webpack support for production

1. Run composer create-project command:

composer create-project samsonasik/ci4-vue

2. Copy file ci4-vue/env to ci4-vue/.env:

cp ci4-vue/env ci4-vue/.env

3. Set environment and app configuration

Open ci4-vue/.env and set CI_ENVIRONMENT, app.baseURL, app.indexPage:

# file ci4-vue/.env
CI_ENVIRONMENT = development

app.baseURL    = 'http://localhost:8080'
app.indexPage  = ''

4. Run PHP Development server

# go to ci4-vue directory
cd ci4-vue

# run php development server inside ci4-vue directory
php spark serve

5. Open web browser http://localhost:8080

For deploy to production purpose, it has webpack.config.js in root directory that when we run webpack command, we can get public/js/dist/bundle.js after run it. If you don't have a webpack installed yet in your system, you can install nodejs and install webpack and webpack-cli:

sudo npm install -g webpack
sudo npm install -g webpack-cli

So, we can run:

webpack

After it generated, we can update .env file as follow:

# file .env
CI_ENVIRONMENT = production

app.baseURL    = 'https://www.your-website.com'
app.indexPage  = ''

In app/Views/layout.php, we have a ENVIRONMENT check to use js/app.js when on development, and use /js/dist/bundle.js on production when exists.

// src/App/templates/layout/default.phtml
<?php $isDevelopment = ENVIRONMENT === 'development'; ?>

// ...
    <script src="<?php echo site_url($isDevelopment
            ? '/js/app.js'
            : (
                // when after run webpack, allow to use bundled js
                // fallback to use /js/app.js when not
                file_exists(ROOTPATH . 'public/js/dist/bundle.js')
                    ? '/js/dist/bundle.js'
                    : '/js/app.js'
            )) ?>" type="module"></script>
// ...

that will automatically take care of that.
