Create A New Processor First, By Invoking It: Use `processor()` Instead Of `processor`.

by ADMIN 88 views

Introduction

As a developer, upgrading your dependencies is an essential part of maintaining a healthy and efficient codebase. However, sometimes these upgrades can lead to unexpected errors. In this article, we'll explore the issue of upgrading to mdsvex@0.12.5 and the resulting processor() error in a Svelte Kit 2 project.

The Error

When upgrading to mdsvex@0.12.5, you may encounter the following error:

Error: processor() is not a function

This error occurs when trying to invoke the processor() function, which is no longer a function in the latest version of mdsvex.

The Cause

The cause of this error lies in the way mdsvex is imported and used in your project. In previous versions of mdsvex, you could import it as a function and use it directly. However, in version 0.12.5, the import syntax has changed.

The Solution

To resolve this error, you need to update your import statement to use the new syntax. Instead of importing mdsvex as a function, you should import it as an object and use its processor property.

Updating Your Code

To update your code, you need to modify your svelte.config.js file. Specifically, you need to change the line where you import and use mdsvex:

- import { mdsvex } from 'mdsvex'
+ import { createMdsvex } from 'mdsvex'

/** @type {import('@sveltejs/kit').Config} */
const config = {
  // Consult https://github.com/sveltejs/svelte-preprocess
  // for more information about preprocessor

  extensions: ['.svelte', ...mdsvexConfig.extensions],
  preprocess: [
    createMdsvex(mdsvexConfig),
    vitePreprocess({
      postcss: true,
    }),
  ],

  kit: {
    adapter: vercelAdapter(),
  },
}

export default config

You also need to update your mdsvex.config.js file to use the new createMdsvex function:

export default {
  extensions: ['.svelte.md', '.md', '.svx'],
  smartypants: {
    dashes: 'oldschool',
  },
  remarkPlugins: [
    [
      remarkGithub,
      {
        repository: 'https://github.com/callmeberzerker/portfolio',
      },
    ],
    remarkAbbr,
  ],
  rehypePlugins: [
    rehypeSlug,
    [
      rehypeAutolinkHeadings,
      {
        behavior: 'wrap',
      },
    ],
    rehypeExternalLinks,
    {
      target: true,
    },
  ],
}

Conclusion

Upgrading to mdsvex@0.12.5 requires some changes to your code. By updating your import statements and using the new createMdsvex function, you can resolve the processor() error and continue using the latest version of mdsvex.
