Improving demo templating maintainability

[amtins]

As Pillarbox maintainer, I'd like to make templating management more developer-friendly, to make maintenance easier.

To achieve this, it would be interesting to investigate the following solutions:

• take advantage of parceljs/posthtml/posthtml-include
• using web components
• html templates

Acceptance criteria

• select the most sustainable approach

After testing and investigating the different technologies listed above here are some feedback I've gathered :

PostHTML:

• Integrated templating framework within Parcel.
• Designed for compile-time use, and dynamic templating is limited.
• Possible to use PostHTML at runtime, but other solutions like Handlebars may be more suitable.

Web Components:

• Suitable solution, but templating is more focused on interpolation rather than bundling HTML files.
• Integrating a lightweight framework like Lit reduces the learning curve significantly.

HTML Template:

• Handlebars is commonly used for HTML templating.
• Templates need precompilation for performance.
• Parcel supports precompilation with plugins (not officially provided by parcel), but availability and maintenance may vary.
