# nuxt-bulma-slim



[Nuxt.js](https://nuxtjs.org) module to automatically make a slim

[Bulma](https://bulma.io) build of used features with

[Purgecss](https://www.purgecss.com). Simply drop in this module and

save precious kilobytes. Also gets rid of annoying warnings for you.



![Demo](./example/assets/images/demo.png)



## Setup



Install the dependency:



```shell

npm install nuxt-bulma-slim

```



Add it to the `modules` section of `nuxt.config.js`:



```javascript

{

  modules: [

    'nuxt-bulma-slim'

  ]

}

```



Or with custom options:



```javascript

{

  modules: [

    [

      'nuxt-bulma-slim',

      {

        variablesPath: 'assets/scss/my-variables.scss',

        additionalPaths: ['assets/scss/component-styles.scss']

      }

    ]

  ]

}

```



## Options



### `srcGlobs`



This is an Array of glob paths. These paths can be absolute or relative to the

Nuxt App `srcDir` option. The Array is passed to Purgecss'

[`content`](https://www.purgecss.com/configuration.html#content) option.



#### Default



```javascript

srcGlobs = [

  '/layouts/**/*.vue',

  '/pages/**/*.vue',

  '/components/**/*.vue'

]

```



### `variablesPath`



This is a String of a path to a `.sass`/`.scss` file that contains variables.

Use this file to overwrite

[Bulma's variables](https://bulma.io/documentation/overview/variables).



Note that the path can be absolute or relative to the Nuxt App `srcDir` option

and must be a `.sass` or `.scss` file.



For convenience this module checks if one of these files exists and

automatically set the `variablesPath` option if you haven't set it already:



- `/assets/sass/variables.sass`

- `/assets/scss/variables.scss`



#### Default



```javascript

variablesPath = null // if none of the above files exist, or ...

variablesPath = '/assets/sass/variables.sass' // or ...

variablesPath = '/assets/scss/variables.scss'

```



### `sassTempPath`



This is a String of a path to the temporary `.sass` file that will be consumed

by Nuxt.



#### Default



```javascript

sassTempPath = '/.tmp/nuxt-bulma-slim.sass'

```



### `cssTempPath`



This is a String of a path to the temporary `.css` file that will be consumed

by Nuxt.



#### Default



```javascript

cssTempPath = '/.tmp/nuxt-bulma-slim.css'

```



### `disablePostCSSWarnings`



This is a Boolean to disable PostCSS warnings when compiling Bulma's SASS to

CSS. If `true`, it will set this option in the Nuxt settings:



```javascript

{

  build: {

    postcss: {

      plugins: {

        'postcss-custom-properties': {

          warnings: false

        }

      }

    }

  }

}

```



Check out the [related issue](https://github.com/nuxt/nuxt.js/issues/1670).



#### Default



```javascript

disablePostCSSWarnings = true

```



### `whitelist`



This is an Array of whitelisted selectors and is given to Purgecss'

[`whitelist`](https://www.purgecss.com/configuration.html#whitelist) option.



Note that `html` and `body` are already whitelisted by this module.



#### Default



```javascript

whitelist = []

```



### `whitelistPatterns`



This is an Array of whitelisted selectors based on RegEx and is given to

Purgecss'

[`whitelistPatterns`](https://www.purgecss.com/configuration.html#whitelistpatterns)

option.



#### Default



```javascript

whitelistPatterns = []

```



### `whitelistPatternsChildren`



This is an Array of whitelisted children selectors based on RegEx and is given

to Purgecss'

[`whitelistPatternsChildren`](https://www.purgecss.com/configuration.html#whitelistpatternschildren)

option.



#### Default



```javascript

whitelistPatternsChildren = []

```



### `additionalPaths`



This is an Array of additional `.sass`/`.scss`/`.css` paths that will be bundled

along with the `variablesPath` and the Bulma build. This is useful if you want

to bundle 3rd party libraries like [Buefy](https://buefy.github.io) that depend

on Bulma.



#### Default



```javascript

additionalPaths = []

```



## How does it work?



In development mode (`nuxt dev`) a temporary `.sass` file is written with your

defined `variablesPath`, the complete Bulma features, and any `additionalPaths`.



Temporary files are written to the Nuxt's `rootDir` in the `.tmp` folder.



This `.sass` file is then injected into the

[`css`](https://nuxtjs.org/api/configuration-css) Array of Nuxt. Since Nuxt can

compile SASS, it will also automatically hot-reload your styles when you change

your variables or additional paths content.



In production mode (`nuxt build`/`nuxt start` & `nuxt generate`), this module

will bundle the SASS just like in development. Additionally it will compile the

SASS to CSS.



This CSS is then run thru Purgecss to minify it, then it is written to a

temporary `.css` file and injected into Nuxt's `css` Array.



## Development



#### `npm test`



Run all the tests.



#### `npm run test:watch`



Re-run specific tests on file changes.



#### `npm run lint`



Lint all the code.



#### `npm run dev`



Run the `./example` Nuxt App in dev mode (will use the whole Bulma library).



#### `npm run build`



Build the example Nuxt App (will only bundle Bulma features that are used).



#### `npm start`



Will start the example Nuxt App in production.



#### `npm run upgrade`



Will start [npm-check](https://github.com/dylang/npm-check) to interactively

upgrade the depeendencies.
