Helix Importer

Foundation tools for importing website content into that can be consumed in an Helix project.

Basic concept of the importer: for an input url, transform the DOM and convert it into a Markdown / docx file.

Importer

An importer must extends PageImporter and implement the fetch and process method. The general idea is that fetch receives the url to import and is responsible to return the HTML. process receives the corresponding Document in order to filter / rearrange / reshuffle the DOM before it gets processed by the Markdown transformer. process computes and defines the list of PageImporterResource (could be more than one), each resource being transformed as a Markdown document.

Goal of the importer is to get rid of the generic DOM elements like the header / footer, the nav... and all elements that are common to all pages in order to get the unique piece(s) of content per page.

HTML2x helpers

HTML2x methods (HTML2md and HTML2docx) are convienence methods to run an import. As input, they take:

  • URL: URL of the page to import
  • document: the DOM element to import - a Document object or a string (see createDocumentFromString for the string case)
  • transformerCfg: object with the transformation "rules". Object can be either:
    • { transformDOM: ({ url, document, html, params }) => { ... return element-to-convert }, generateDocumentPath: ({ url, document, html, params }) => { ... return path-to-target; }} for a single mapping between one input document / one output file
    • { transform: ({ url, document, html, params }) => { ... return [{ element: first-element-to-convert, path: first-path-to-target }, ...] } for a mapping one input document / multiple output files (useful to generate multiple docx from a single web page)
  • config: object with several config properties
    • createDocumentFromString: this config is required if you use the methods in a non-browser context and want to pass document param as string. This method receives the HTML to parse as a string and must return a Document object.
    • setBackgroundImagesFromCSS: set to false to disable the background-image inlining in the DOM.
