Features

• Add custom metadata to files within the weh files array
• Custom filter functions to include or exclude files from transforms

Installation

npm install --save @weh/metadata

Usage example

const weh = require('@weh/weh')
const metadata = require('@weh/metadata')

// metadata object
// a JavaScript object that you want to each to files in the weh array
const myMetaData = {
  name: 'My awesome website'
}

// enter our main function:
// the main function should be an async function so that
// it automatically returns a promise
weh(async site => {
  // we register our plugin...
  site.use(metadata, {metadata: myMetaData})
  // ...and initiate the build process
  return site
})

Filter example

You can pass a custom filter as an option to metadata to include or exclude files.

A filter is a function that takes the arguments file, options, and files. file is the current file, options is the options object passed to metadata, and files is the entire array of files created by weh.

When the filter function returns true, metadata applies its transforms to the current file object. Otherwise the file object remains unchanged.

The default filter in metadata always returns true, so the transform will be applied to every file:

function filter (file, options, files) {
  return true
}

This is how you could use a filter to only apply metadata to files ending with .md:

const weh = require('@weh/weh')
const metadata = require('@weh/metadata')

// metadata object
// a JavaScript object that you want to each to files in the weh array
const myMetaData = {
  name: 'My awesome website'
}

// custom filter function
// returns true if file path ends with '.md'
function myCustomFilter (file, options, files) {
  return file.path.endsWith('.md')
}

weh(async site => {
  // we register the metadata plugin with our custom filter function...
  site.use(metadata, {
    metadata: myMetaData,
    filter: myCustomFilter
  })
  // ...and initiate the build process
  return site
})

How does it work?

metadata takes any JavaScript object and writes it to the metadata property of files in the weh array.
