# svelte-sequential-preprocessor

> A [Svelte](https://svelte.dev) preprocessor that wraps preprocessors to force them to be called sequentially.

## Overview

Svelte evaluates preprocessors by running all markup preprocessors first, then script and finally styles.  Some preprocesses may not work if other preprocessors haven't been run.  For example, [svelte-image](https://github.com/matyunya/svelte-image) uses `svelte.parse()` internally, so [svelte-preprocess](https://github.com/sveltejs/svelte-preprocess) needs to be run before if any scss is present.

## Installation

Using npm:

```bash

$ npm i -D svelte-sequential-preprocessor

```

## Usage

### With `rollup-plugin-svelte`

```js

// rollup.config.js

import svelte from 'rollup-plugin-svelte';

import seqPreprocessor from 'svelte-sequential-preprocessor'

import autoPreprocess from 'svelte-preprocess'

import image from 'svelte-image'

export default {

  ...,

  plugins: [

    svelte({

      preprocess: seqPreprocessor([ autoPreprocess(), image() ])

    })

  ]

}

```

### With `svelte-loader`

```js

  ...

  module: {

    rules: [

      ...

      {

        test: /\.(html|svelte)$/,

        exclude: /node_modules/,

        use: {

          loader: 'svelte-loader',

          options: {

            preprocess: require('svelte-sequential-preprocessor')([ require('svelte-preprocess'), require('svelte-image')])

          },

        },

      },

      ...

    ]

  }

  ...

```

### With Sapper

```js

import seqPreprocessor from 'svelte-sequential-preprocessor';

import autoPreprocess from 'svelte-preprocess'

import image from 'svelte-image'

const preprocess = seqPreprocessor([ autoPreprocess(), image() ]);

export default {

  client: {

    plugins: [

      svelte({

        preprocess,

        // ...

      }),

  },

  server: {

    plugins: [

      svelte({

        preprocess,

        // ...

      }),

    ],

  },

};

```
