Vue cli don t minify html

Webpack is an essential tool for developing Vue. It makes your development workflow much simpler by managing complex build steps and can optimise your apps size and performance.

Note: this article was originally posted here on the Vue. If you're using a template to build your app from vue-clia pre-made Webpack config is provided.

They're well optimised and there are no improvements I can suggest! But since they work so well out of the box, you probably don't have much idea of what they're really doing, right?

HTML minifier

Consider this article an overview of the Webpack config used in the vue-cli templates, as they include the same optimisations I'm discussing here. These come with an intrinsic problem, though: either your HTML markup needs to be in an awkward JavaScript string, or your template and component definition will need to be in separate files, making them hard to work with.

SFCs are made possible by the vue-loader Webpack plugin. This loader splits up the SFCs language blocks and pipes each to an appropriate loader, e. The final output of vue-loader is a JavaScript module ready for inclusion in your Webpack bundle. You can reduce your bundle size by omitting the compiler from the Webpack build. There is a runtime-only build of the Vue. It's about 20KB smaller than the full build so it's worth using if you can. The runtime-only build is used by default, so every time you use import vue from 'vue'; in your project that's what you'll get.

You can change to a different build, though, by using the alias configuration option:. Another way to reduce your Vue. These bloat your output bundle size with unnecessary code and also incur a runtime cost you're best to avoid.

Production Deployment

If you inspect the Vue source code you'll see that warning blocks are conditional on the value of an environment variable process. If process. You can use the DefinePlugin to set the value of process. A user's browser will cache your site's files so that they'll only download if the browser does not already have a local copy, or if the local copy has expired.

If all your code is in one file, then a tiny change would mean the whole file would need to be re-downloaded. Ideally you want your users to download as little as possible, so it'd be smart to separate your app's rarely changing code from its frequently changing code.

The Common Chunks plugin can decouple your vendor code e. If you do this you'll now have two separate files in your build output which will be cached by the browser independently:. By default, only when a cached file expires, or when the user manually clears the cache, will the browser request the file again from the server.

The file will be re-downloaded if the server indicates the file has changed otherwise the server return HTTP Not Modified. To save an unnecessary server request, we can change a file's name every time its content changes to force the browser to re-download it.

A simple system for doing this is to add a "fingerprint" to the file name by appending a hash e. The Common Chunks plugin emits a "chunkhash" which is updated if the file's content has changed. Webpack can append this hash to the file names when they're outputted:.

When you do this, you'll see that your outputted files will have names like app. Of course if you add a hash you'll have to update the reference to the file in your index file, otherwise the browser won't know about it:.

This plugin can auto inject references to the build files into your HTML file in the bundling process. Now your build files with hashes will automatically be added to your index file. Also, your index. By default, Webpack will output all your apps code into one large bundle. But if your app has multiple pages it would be more efficient to split the code so each individual pages code is in a separate file, and is only loaded when needed.Sponsor webpack and get apparel from the official shop!

All proceeds go to our open collective! This plugin extracts CSS into separate files. It's recommended to combine mini-css-extract-plugin with the css-loader. There are some cases in which using ES modules is beneficial, like in the case of module concatenation and tree shaking. This plugin should be used only on production builds without style-loader in the loaders chain, especially if you want to have HMR in development.

Here is an example to have both HMR in development and your styles extracted in a file for production builds. The mini-css-extract-plugin supports hot reloading of actual css files in development. While we attempt to hmr css-modules.

It is not easy to perform when code-splitting with custom chunk names. The core challenge with css-modules is that when code-split, the chunk ids can and do end up different compared to the filename. To minify the output, use a plugin like optimize-css-assets-webpack-plugin. Setting optimization. When inlining CSS data-href must be used.

You may also extract the CSS based on the webpack entry name. This is especially useful if you import routes dynamically but want to keep your CSS bundled according to entry. With the moduleFilename option you can use chunk data to customize the filename. In the example below, we'll use moduleFilename to output the generated css into a different directory.

For long term caching use filename: "[contenthash]. Optionally add [name].GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. If nothing happens, download GitHub Desktop and try again.

Is your feature request related to a problem? Please describe. Describe the solution you'd like For the minify feature and the dependency on the html-minifier package to be removed in the next major version of html-webpack-plugin ie v4 on the webpack-4 branch.

This idea was previously mentioned in and Describe alternatives you've considered Leaving the html-minifier dependency as-is in v4.

Furthermore it will only pick up html-webpack-plugin files if it is added after the html-webpack-plugin. Webpack itself also ships with a built in js minifier.

Ah good point about html-minifier-webpack-plugin not using caching, whereas the minify feature here does. If we were to go with 1which minify options would we enable? Given some are potentially unsafe. Using any option that isn't used by the projects above is probably risky, since a they probably had good reason not to enable it, b it's not getting as much real-world coverage. One other thing we would need to decide, is whether any user-provided minify options should be merged into the proposed defaults above, or completely override them?

The former would save them having to copy-paste all options into their project when they only want to tweak it slightly - so perhaps it makes most sense? I would rather go for explicit over implicit and not merge it you would just get what you configured and nothing else. However if most users expect it to be merged we can also merge it.

Merging would be your preferred way wouldn't it? The Python part of me does prefer explicit over implicit too, so I agree not merging might actually be best Looking at conservativeCollapse more closely, I don't think we need or want to use it.

The examples given in the doc linked above now preserve whitespace correctly, even without using conservativeCollapse. For example try this in the online minifier :. As such, I think we should just use standard collapseWhitespace without enabling conservativeCollapse for now.

I've updated the suggested config above accordingly.Running tsc locally will compile the closest project defined by a tsconfig. TypeScript 3. Get the latest version today!

This section is only relevant if you are using a custom build setup. During development, Vue provides a lot of warnings to help you with common errors and pitfalls.

In addition, some of these warning checks have small runtime costs that can be avoided in production mode. If you are using the full build, i. Both versions can be found in the Installation guide. When using a build tool like Webpack or Browserify, the production mode will be determined by process. All vue-cli templates have these pre-configured for you, but it would be beneficial to know how it is done:.

This tells vueify to avoid including hot-reload and development related code. Apply a global envify transform to your bundle. For example:. Or, using envify with Gulp:. Or, using envify with Grunt and grunt-browserify :. When using in-DOM templates or in-JavaScript template strings, the template-to-render-function compilation is performed on the fly. This is usually fast enough in most cases, but is best avoided if your application is performance-sensitive.

The easiest way to pre-compile templates is using Single-File Components - the associated build setups automatically performs pre-compilation for you, so the built code contains the already compiled render functions instead of raw template strings. If you are using Webpack, and prefer separating JavaScript and template files, you can use vue-template-loaderwhich also transforms the template files into JavaScript render functions during the build step.

Extracting the CSS across all components into the same file will avoid these issues, and also result in better CSS minification and caching. It might be a good idea to leverage this hook together with an error-tracking service like Sentrywhich provides an official integration for Vue.

This allows vue-cli to be used in environments where there is development inside another larger server backend e.

I understand that it requires a removal of the hashing of the names, but usually hashing is the responsibility of the server not the UI framework so I'm ok if this doesn't including hashing. This isn't about filenamehashing, it's out having no template or index name. Not every build needs to do a replacement to an index. I just mentioned filenameHashing in that this feature doesn't need to work with filenameHashing enabled because of the inherent problems with filenameHashing and not creating the HTML file.

If you don't need the generated index. Actually the html-webpack-plugin does a lot of things underlylingly. So, removing it will add complexity.

Also, documentation need to be added for things like modern mode without index. So I'm reluctant to do this…. I'm also want to build without index. Ant this is heplful. Skip to content.
