Copy local page assets to permalink folder

Instalation

Available on npm

npm install eleventy-plugin-page-assets --save-dev

Open up your Eleventy config file (probably .eleventy.js) and use addPlugin:

FILENAME .eleventy.js

const pageAssetsPlugin = require('eleventy-plugin-page-assets');

module.exports = function(eleventyConfig) {
    eleventyConfig.addPlugin(pageAssetsPlugin, {
        mode: "parse",
        postsMatching: "src/posts/*/*.md",
    });
};

How it works

This folder structure

📁 src/posts/
  📁 some-title/
    📄 index.md <-- when a template file is processed
    🖼 cover.png    assets relative to it are automatically
    🖼 image.jpg    copied to the permalink folder
  📁 good-title/
    📄 index.md 
    🖼 cover.png
  📁 bar-title/
    📄 index.md
    📁 icons/ 
      🖼 icon.png
  📄 my-post.md
  🖼 img.png

Will generate this output

📁 dist/
  📁 perma-some-title/
    📄 index.html 
    🖼 89509eae15a24c2276d54d4b7b28194a1391ee48.png 
    🖼 63d8ddb9ffadd92e3d9a95f0e49ae76e7201a672.jpg 
  📁 perma-good-title/
    📄 index.html 
    🖼 d0017352f4da463a61a83a1bc8baf539a4c921c1.png
  📁 perma-bar-title/
    📄 index.md
    🖼 faa22a543b2dcb21fdd9b7795095e364ef00d540.png
  📁 perma-my-post/
    📄 index.md

Directory mode

On directory mode the template is not parsed, assets on the same level as template are copied to the permalink folder, even if not used.

Note: Paths are not rewritten and folder structure is kept inside the perma folder.

This mode is cheaper as it does not parses the html or transforms it.

Options

Option	Required	Type	Default	Description
mode	false	string	parse	Parse mode will resolve assets referenced inside the template. Directory mode blindly copies files on the folder as the template.
postsMatching	false	string	"*.md"	Pattern (glob) filtering which templates to process
assetsMatching	false	string	".png	.jpg	*.gif"	Specify a pattern (glob) that matches which assets are going to be resolved
recursive	false	boolean	false	Recursively scan assets under subdirectories (example src/posts/foo/bar/baz/img.jpg) (directory mode only)
hashAssets	false	boolean	true	Rewrite filenames to hashes. This will flatten the paths to always be next to the post .html file. (parse mode only)
hashingAlg	false	string	sha1	Hashing algorithm sha1	md5	sha256	sha512 <https://nodejs.org/api/crypto.html#crypto_crypto_createhash_algorithm_optionsetc (parse> mode only)
hashingDigest	false	string	hex	Digest of the hash hex	base64 (parse mode only)
addIntegrityAttribute	false	boolean	false	Add a integrity attribute to the tag (parse mode only)

TO-DO:

• Parse the rendered html files looking for assets, and only used imported assets (similat to how what webpack loaders work)
• Rewrite paths on the output files, possibly renaming files to md5 hashes, so images also have permalinks.
• Write tests
