I wanted to set title to my webpage created with vue cli 3 and thus looked into public/index.html. There, I found <title><%= htmlWebpackPlugin.options.title %></title>.
How do I set and modify htmlWebpackPlugin.options.title in vue cli 3 project?

vue. config. js is an optional config file that will be automatically loaded by @vue/cli-service if it's present in your project root (next to package. json ).
You can add Vue functionality to existing project without Vue CLI. Preferably a project using Webpack as bundler...then it is pretty simple. You need 3 packages: vue@next, @vue/compiler-sfc and vue-loader and add some rule configuration in your webpack. config.
The CLI ( @vue/cli ) is a globally installed npm package and provides the vue command in your terminal. It provides the ability to quickly scaffold a new project via vue create . You can also manage your projects using a graphical user interface via vue ui .
Looking at the popularity of the question, I decided to add an elaborate answer with references to make it more authentic and complete. I have also created an article on this topic and covered this topic in this and this courses.
Though the question is looking for setting htmlWebpackPlugin.options.title, the ultimate effect is changing the title of the web-page.
The simplest way to do this is to modify the public/index.html and hard-code the title.
<!DOCTYPE html>
<html lang="">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<link rel="icon" href="<%= BASE_URL %>favicon.ico">
<title>
<%= htmlWebpackPlugin.options.title %>
</title>
</head>
<body>
<noscript>
<strong>We're sorry but <%= htmlWebpackPlugin.options.title %> doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>
</noscript>
<div id="app"></div>
<!-- built files will be auto injected -->
</body>
</html>
This is the default public/index.html that is generated by vue cli. And in this, you just need to change
<title>
<%= htmlWebpackPlugin.options.title %>
</title>
to
<title>Title of your choice</title>
name field in package.json
Another simple solution is to change the "name": "your-project-name". However, there are many restrictions on the name you can use in package.json. You can read more about this here. Basically, package.json must contain a name and that must be lowercase and one word, and may contain hyphens and underscores.
pages field in vue.config.js
vue.config.js is an optional file that you can add to provide additional configurations to Vue CLI and this file, if present, will be automatically loaded by Vue CLI. You need to create vue.config.js in the root folder - the folder containing you package.json file.
According to Vue documentation, you can use pages field to define entrypoint for multi-page app. However, you can also use this to define title for single page app as well. Create vue.config.js in the root directory and add pages field to your exports as follows:
module.exports = {
pages: {
index: {
// entry for the page
entry: 'src/main.js',
title: 'My Title',
},
}
}
Note that if you are already running development server, this change will be reflected only when you stop and restart the development server. In other words, these changes will not be hot reloaded.
You can chain Webpack in vue.config.js as shown below
module.exports = {
chainWebpack: config => {
config
.plugin('html')
.tap(args => {
args[0].title = "My Vue App";
return args;
})
}
}
Note that similar to solution 3, this change will be reflected only when you stop and restart the development server, in case you are already running development server. In other words, these changes will not be hot reloaded.
The next solution in the list is to use JavaScript to modify the title. You can do this either in mounted lifecycle hook of your root component or if you want different title for different routes, you can do the same for components loaded by each route.
<script>
export default {
data() {
return {
//
};
},
mounted() {
document.title = 'new title'
}
}
</script>
Finally you can use Vue Meta to manage all metadata for your Vue app including title. First you need to add Vue Meta to your project and then use metaInfo field as shown below to configure metadata for your page or route.
{
metaInfo: {
meta: [
{ charset: 'utf-8' },
{ name: 'viewport', content: 'width=device-width, initial-scale=1' },
{ title: 'My title'}
]
}
}
The first 4 solutions are static ways of changing your title or in other words you can't change your title at runtime using these ways. Also all of these are not hot reloaded. The last 2 options use JavaScript and can manipulate the title at runtime.

create a file vue.config.js at the root
//vue.config.js
module.exports = {
chainWebpack: config => {
config
.plugin('html')
.tap(args => {
args[0].title = "My Vue App";
return args;
})
}
}
