## Explanation of Build Files
|
|
|
|
| | UMD | CommonJS | ES Module |
|
|
| --- | --- | --- | --- |
|
|
| **Full** | vue.js | vue.common.js | vue.esm.js |
|
|
| **Runtime-only** | vue.runtime.js | vue.runtime.common.js | vue.runtime.esm.js |
|
|
| **Full (production)** | vue.min.js | | |
|
|
| **Runtime-only (production)** | vue.runtime.min.js | | |
|
|
|
|
### Terms
|
|
|
|
- **Full**: builds that contains both the compiler and the runtime.
|
|
|
|
- **Compiler**: code that is responsible for compiling template strings into JavaScript render functions.
|
|
|
|
- **Runtime**: code that is responsible for creating Vue instances, rendering and patching virtual DOM, etc. Basically everything minus the compiler.
|
|
|
|
- **[UMD](https://github.com/umdjs/umd)**: UMD builds can be used directly in the browser via a `<script>` tag. The default file from Unpkg CDN at [https://unpkg.com/vue](https://unpkg.com/vue) is the Runtime + Compiler UMD build (`vue.js`).
|
|
|
|
- **[CommonJS](http://wiki.commonjs.org/wiki/Modules/1.1)**: CommonJS builds are intended for use with older bundlers like [browserify](http://browserify.org/) or [webpack 1](https://webpack.github.io). The default file for these bundlers (`pkg.main`) is the Runtime only CommonJS build (`vue.runtime.common.js`).
|
|
|
|
- **[ES Module](http://exploringjs.com/es6/ch_modules.html)**: ES module builds are intended for use with modern bundlers like [webpack 2](https://webpack.js.org) or [rollup](http://rollupjs.org/). The default file for these bundlers (`pkg.module`) is the Runtime only ES Module build (`vue.runtime.esm.js`).
|
|
|
|
### Runtime + Compiler vs. Runtime-only
|
|
|
|
If you need to compile templates on the fly (e.g. passing a string to the `template` option, or mounting to an element using its in-DOM HTML as the template), you will need the compiler and thus the full build.
|
|
|
|
When using `vue-loader` or `vueify`, templates inside `*.vue` files are compiled into JavaScript at build time. You don't really need the compiler in the final bundle, and can therefore use the runtime-only build.
|
|
|
|
Since the runtime-only builds are roughly 30% lighter-weight than their full-build counterparts, you should use it whenever you can. If you wish to use the full build instead, you need to configure an alias in your bundler.
|
|
|
|
#### Webpack
|
|
|
|
``` js
|
|
module.exports = {
|
|
// ...
|
|
resolve: {
|
|
alias: {
|
|
'vue$': 'vue/dist/vue.esm.js' // 'vue/dist/vue.common.js' for webpack 1
|
|
}
|
|
}
|
|
}
|
|
````
|
|
|
|
#### Rollup
|
|
|
|
``` js
|
|
const alias = require('rollup-plugin-alias')
|
|
|
|
rollup({
|
|
// ...
|
|
plugins: [
|
|
alias({
|
|
'vue': 'vue/dist/vue.esm.js'
|
|
})
|
|
]
|
|
})
|
|
```
|
|
|
|
#### Browserify
|
|
|
|
Add to your project's `package.json`:
|
|
|
|
``` js
|
|
{
|
|
// ...
|
|
"browser": {
|
|
"vue": "vue/dist/vue.common.js"
|
|
}
|
|
}
|
|
```
|
|
|
|
### Development vs. Production Mode
|
|
|
|
Development/production modes are hard-coded for the UMD builds: the un-minified files are for development, and the minified files are for production.
|
|
|
|
CommonJS and ES Module builds are intended for bundlers, therefore we don't provide minified versions for them. You will be responsible for minifying the final bundle yourself.
|
|
|
|
CommonJS and ES Module builds also preserve raw checks for `process.env.NODE_ENV` to determine the mode they should run in. You should use appropriate bundler configurations to replace these environment variables in order to control which mode Vue will run in. Replacing `process.env.NODE_ENV` with string literals also allows minifiers like UglifyJS to completely drop the development-only code blocks, reducing final file size.
|
|
|
|
#### Webpack
|
|
|
|
Use Webpack's [DefinePlugin](https://webpack.js.org/plugins/define-plugin/):
|
|
|
|
``` js
|
|
var webpack = require('webpack')
|
|
|
|
module.exports = {
|
|
// ...
|
|
plugins: [
|
|
// ...
|
|
new webpack.DefinePlugin({
|
|
'process.env': {
|
|
NODE_ENV: JSON.stringify('production')
|
|
}
|
|
})
|
|
]
|
|
}
|
|
```
|
|
|
|
#### Rollup
|
|
|
|
Use [rollup-plugin-replace](https://github.com/rollup/rollup-plugin-replace):
|
|
|
|
``` js
|
|
const replace = require('rollup-plugin-replace')
|
|
|
|
rollup({
|
|
// ...
|
|
plugins: [
|
|
replace({
|
|
'process.env.NODE_ENV': JSON.stringify('production')
|
|
})
|
|
]
|
|
}).then(...)
|
|
```
|
|
|
|
#### Browserify
|
|
|
|
Apply a global [envify](https://github.com/hughsk/envify) transform to your bundle.
|
|
|
|
``` bash
|
|
NODE_ENV=production browserify -g envify -e main.js | uglifyjs -c -m > build.js
|
|
```
