Options

`root`

Type: string
Default: ./

Root path for modules lookup.

`plugins`

Type: array | function
Default: []

PostHTML plugins to apply for every parsed module.

If a function provided, it will be called with module's file path.

`from`

Type: string
Default: ''

Root filename for processing apply, needed for path resolving (it's better to always provide it).

`initial`

Type: boolean
Default: false

Apply plugins to root file after modules processing.

`tag`

Type: string
Default: module

Use a custom tag name.

`attribute`

Type: string
Default: href

Use a custom attribute name.

`locals`

Type: object
Default: {}

Pass data to the module.

If present, the JSON object from the locals="" attribute will be merged on top of this, overwriting any existing values.

`attributeAsLocals`

Type: boolean
Default: false

All attributes on <module></module> will be added to locals

`parser`

Type: object
Default: {}

Options for the PostHTML parser.

By default, posthtml-parser is used.

`expressions`

Type: object
Default: {}

Options to forward to posthtml-expressions, like custom delimiters for example. Available options can be found here.

Component options

`locals`

You can pass data to a module using a locals="" attribute.

Must be a valid JSON object.

Example:

<!-- module.html -->
<p>The foo is {{ foo }} in this one.</p>
<content></content>

<!-- index.html -->
<module href="./module.html" locals='{"foo": "strong"}'>
  <p>Or so they say...</p>
</module>

Result

<p>The foo is strong in this one.</p>
<p>Or so they say...</p>

`attributeAsLocals`

All attributes on <module></module> will be added to locals

Example:

<!-- module.html -->
<div class="{{ class }}" id="{{ id }}" style="{{ style }}">
  <content></content>
</div>

<!-- index.html -->
<module 
  href="module.html" 
  class="text-center uppercase" 
  id="example"
  style="display: flex; gap: 2;"
>
  Module content
</module>

Result

<div class="text-center uppercase" id="example" style="display: flex; gap: 2;">
  Module content
</div>
