Render to HTML Leave feedback

When rendering to HTML, GroupDocs.Viewer renders each page of the source document as a separate HTML document.

GroupDocs.Viewer for Node.js provides two options to manage CSS, fonts, images, and other resources:

1. HTML with external resources stores page resources as separate files. This allows reusing common resources and results in reducing page size and loading speed.
2. HTML with embedded resources integrates page resources into HTML. This makes each document page self-sufficient but results in increasing page size and loading speed.

To render files to HTML, follow these steps:

1. Create an instance of the Viewer class. Specify the source document path as a constructor parameter.
2. Instantiate the HtmlViewOptions object. Specify a path to save the rendered pages.
3. Call the View.view() method of the Viewer object. Specify the HtmlViewOptions object as the parameter.

The following code snippet shows how to render a .docx document to HTML with external resources:

const viewer = new groupdocs.viewer.Viewer("sample.docx")
// Create an HTML file for each page.
// Specify the HTML file names and location of external resources.
// {0} and {1} are replaced with the current page number and resource name, respectively.
const viewOptions = groupdocs.viewer.HtmlViewOptions.forExternalResources("page_{0}.html", "page_{0}/resource_{0}_{1}", "page_{0}/resource_{0}_{1}")
viewer.view(viewOptions)

The following code snippet shows how to render a .docx document to HTML with embedded resources:

const viewer = new groupdocs.viewer.Viewer("sample.docx")
// Create an HTML files.
// {0} is replaced with the current page number in the file name.
const viewOptions = groupdocs.viewer.HtmlViewOptions.forEmbeddedResources("page_{0}.html")
viewer.view(viewOptions)
