Simply set the title in the vue.config.js inside the pages configuration:

// vue.config.js
module.exports = {
  pages: {
    index: {
      title: 'Your Page Title',
    },
  },
};

Don't forget to include <title><%= htmlWebpackPlugin.options.title %></title> in your index.html file for this to take effect. Also, if your use-case demands, runtime title updates can be achieved using Vue Meta or JavaScript. More on these below!

Vue Meta: Metadata Management Guru

Vue Meta is a Japanese sensei for maintaining your Vue app's metadata! Install it (npm install vue-meta), use it in your main.js and define the metadata (including title) in your Vue components. Check how easy-peasy it is:

// Who needs Chuck Norris if you've got Vue Meta? 😄
import Vue from 'vue';
import VueMeta from 'vue-meta';

Vue.use(VueMeta);

Now, you can define the title in your components:

// Your component is now a horseshoe to my foot…
export default {
  metaInfo: {
    title: 'Dynamic Page Title',
    // Populate more meta tags as you please...
  }
}

Vue Meta supports real-time updates and works well with SSR (Server-Side Rendering).

JavaScript: Native DIY Method

Need to change the title at runtime? Just use JavaScript in your component's mounted hook:

// Look mum, no external libraries! 💪
mounted() {
  document.title = 'Your Dynamic Title';
}

Static Title: Minimalist's Choice

Hardcoding: The Old School Style

You can set the title directly in the public/index.html file. It's as simple as:

<!-- I’m HTML5 and I was here first! -->
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Your Static Page Title</title>
</head>
<body>
    <div id="app"></div>
</body>
</html>

Webpack Chain: For the Inner Control Freak

Alternatively, you can talk directly to Webpack via the chainWebpack property:

// Chain me up, Scotty! 🛸
module.exports = {
  chainWebpack: config => {
    config.plugin('html')
      .tap(args => {
        args[0].title = 'Your Page Title';
        return args;
      });
  }
}

Remember to restart your server after changes to vue.config.js, as these don't support hot reloading.

Environmental Wisdom: A Title for Every occasion

Environment Variables: The Swiss Army Knife Approach

Keeping title as an environment variable allows you to pivot it as per the respective environment. You need a .env file in your project root - like .env.development or .env.production. Set your titles like VUE_APP_TITLE=My Awesome App and then access them within your app:

// I see dead variables 👻
mounted() {
  document.title = process.env.VUE_APP_TITLE;
}

It's like having unique headgear for every occasion!

Don’t Forget UX: Titles Matter!

Ensure your title reflects your app and makes sense for the user – remember, UX comes first!

Common Traps and Triumphs

Title Updates MIA

Changes not showing up after updates in vue.config.js? Restart your server – hot reloading doesn't cover these changes.

Missing Dynamic Title Updates

Not seeing live title updates? Make sure you're using Vue Meta or setting document.title in a mounted hook.

Title Not Reading Environment Variable

Ensure environment variables carry the VUE_APP_ prefix to be accessible in your Vue app.
