  • Neutrino v8

Installation

@neutrinojs/vue can be installed via the Yarn or npm clients. Inside your project, make sure neutrino and @neutrinojs/vue are development dependencies. You will also need Vue for actual Vue development.

Yarn

❯ yarn add --dev neutrino @neutrinojs/vue
❯ yarn add vue

npm

❯ npm install --save-dev neutrino @neutrinojs/vue
❯ npm install --save vue

Project Layout

@neutrinojs/vue follows the standard project layout specified by Neutrino. This means that by default all project source code should live in a directory named src in the root of the project. This includes JavaScript files, CSS stylesheets, images, and any other assets that would be available to import your compiled project.

Quickstart

The fastest way to get started is by using the create-project scaffolding tool. Don’t want to use the CLI helper? No worries, we have you covered with the manual installation.

create-project

Run the following command to start the process. Substitute <directory-name> with the directory name you wish to create for this project.

Yarn

❯ yarn create @neutrinojs/project <directory-name>

Note: The create command is a shorthand that helps you do two things at once. See the Yarn create docs for more details.

npm/npx

npx comes pre-installed with npm. If you’re running an older version of npm, then npm install -g npm to update to the latest version.

❯ npx @neutrinojs/create-project <directory-name>

The CLI helper will prompt for the project to scaffold, and will offer to set up a test runner as well as linting to your project. Refer to the Create new project section for details on all available options.

Manual Installation

After installing Neutrino and the Vue preset, add a new directory named src in the root of the project, with two files index.js and App.vue in it.

❯ mkdir src && touch src/index.js && touch src/App.vue

This Vue preset exposes an element in the page with an ID of root to which you can mount your application. Edit your src/index.js file with the following:

import Vue from 'vue';
import App from './App.vue';
 
new Vue({
  el: '#root',
  render: (h) => h(App),
});

Next, edit your src/App.vue with the following:

<script>
  export default {
    name: 'App',
    data() {
      return {};
    }
  };
</script> 
 
<template>
  <div>
    <h1>Hello world!</h1>
  </div>
</template>

Now edit your project's package.json to add commands for starting and building the application:

{
  "scripts": {
    "start": "neutrino start --use @neutrinojs/vue",
    "build": "neutrino build --use @neutrinojs/vue"
  }
}

If you are using .neutrinorc.js, add this preset to your use array instead of --use flags:

module.exports = {
  use: ['@neutrinojs/vue']
};

Yarn

❯ yarn start
✔ Development server running on: http://localhost:5000
✔ Build completed

npm

❯ npm start
✔ Development server running on: http://localhost:5000
✔ Build completed

Start the app, then open a browser to the address in the console:

Building

@neutrinojs/vue builds static assets to the build directory by default when running neutrino build. Using the quick start example above as a reference:

❯ yarn build
 
✔ Building project completed
Hash: b26ff013b5a2d5f7b824
Version: webpack 3.5.6
Time: 9773ms
                           Asset       Size    Chunks             Chunk Names
   index.dfbad882ab3d86bfd747.js     181 kB     index  [emitted]  index
 runtime.3d9f9d2453f192a2b10f.js    1.51 kB   runtime  [emitted]  runtime
                      index.html  846 bytes            [emitted]
✨  Done in 14.62s.

You can either serve or deploy the contents of this build directory as a static site.

Static assets

If you wish to copy files to the build directory that are not imported from application code, you can place them in a directory within src called static. All files in this directory will be copied from src/static to build/static. To change this behavior, specify your own patterns with @neutrinojs/copy.

Paths

The @neutrinojs/web preset loads assets relative to the path of your application by setting Webpack's output.publicPath to ./. If you wish to load assets instead from a CDN, or if you wish to change to an absolute path for your application, customize your build to override output.publicPath. See the Customizing section below.

Preset options

You can provide custom options and have them merged with this preset's default options to easily affect how this preset builds. You can modify Vue preset settings from .neutrinorc.js by overriding with an options object. Use an array pair instead of a string to supply these options in .neutrinorc.js.

The following shows how you can pass an options object to the Vue preset and override its options. See the Web documentation for specific options you can override with this object.

module.exports = {
  use: [
    ['@neutrinojs/vue', {
      /* preset options */
 
      // Example: disable Hot Module Replacement
      hot: false,
 
      // Example: change the page title
      html: {
        title: 'Epic Vue App'
      },
 
      // Target specific browsers with babel-preset-env
      targets: {
        browsers: [
          'last 1 Chrome versions',
          'last 1 Firefox versions'
        ]
      },
 
      // Add additional Babel plugins, presets, or env options
      babel: {
        // Override options for babel-preset-env:
        presets: [
          ['babel-preset-env', {
            modules: false,
            useBuiltIns: true,
            exclude: ['transform-regenerator', 'transform-async-to-generator'],
          }]
        ]
      }
    }]
  ]
};

Customizing

To override the build configuration, start with the documentation on customization. @neutrinojs/vue creates some conventions to make overriding the configuration easier once you are ready to make changes. Most of the configuration for @neutrinojs/vue is inherited from the @neutrinojs/web preset; continue to that documentation for details on customization.

By default Neutrino, and therefore this preset, creates a single main index entry point to your application, and this maps to the index.* file in the src directory. The extension is resolved by webpack. This value is provided by neutrino.options.mains at neutrino.options.mains.index. This means that the Web preset is optimized toward the use case of single-page applications over multi-page applications. If you wish to output multiple pages, you can detail all your mains in your .neutrinorc.js.

module.exports = {
  options: {
    mains: {
      index: 'index', // outputs index.html from src/index.*
      admin: 'admin', // outputs admin.html from src/admin.*
      account: 'user' // outputs account.html from src/user.*
    }
  },
  use: ['@neutrinojs/vue']
}

Rules

The following is a list of additional rules and their identifiers this preset defines, in addition to the ones provided by @neutrinojs/web, which can be overridden:

Name Description Environments and Commands
vue Compiles Vue files from the src directory using Babel and vue-loader. Contains a single loader named vue. all

Plugins

This preset does not define any additional plugins from those already in use by @neutrinojs/web.

Advanced configuration

By following the customization guide and knowing the rule, loader, and plugin IDs from @neutrinojs/web and above, you can override and augment the build by providing a function to your .neutrinorc.js use array. You can also make these changes from the Neutrino API in custom middleware.

Vendoring

By defining an entry point named vendor you can split out external dependencies into a chunk separate from your application code.

Example: Put Vue into a separate "vendor" chunk:

module.exports = {
  use: [
    '@neutrinojs/vue',
    (neutrino) => {
      neutrino.config
        .entry('vendor')
          .add('vue');
    }
  ]
};
