Docx rendering library

Demo - https://volodymyrbaydalka.github.io/docxjs/

Goal
----
Goal of this project is to render/convert DOCX document into HTML document with keeping HTML semantic as much as possible.
That means library is limited by HTML capabilities (for example Google Docs renders *.docx document on canvas as an image).

Installation
-----
``
npm install docx-preview
`

Usage
-----
`html

`
API
---
`ts
// renders document into specified element
renderAsync(
document: Blob | ArrayBuffer | Uint8Array, // could be any type that supported by JSZip.loadAsync
bodyContainer: HTMLElement, //element to render document content,
styleContainer: HTMLElement, //element to render document styles, numbeings, fonts. If null, bodyContainer will be used.
options: {
className: string = "docx", //class name/prefix for default and document style classes
inWrapper: boolean = true, //enables rendering of wrapper around document content
hideWrapperOnPrint: boolean = false, //disable wrapper styles on print
ignoreWidth: boolean = false, //disables rendering width of page
ignoreHeight: boolean = false, //disables rendering height of page
ignoreFonts: boolean = false, //disables fonts rendering
breakPages: boolean = true, //enables page breaking on page breaks
ignoreLastRenderedPageBreak: boolean = true, //disables page breaking on lastRenderedPageBreak elements
experimental: boolean = false, //enables experimental features (tab stops calculation)
trimXmlDeclaration: boolean = true, //if true, xml declaration will be removed from xml documents before parsing
useBase64URL: boolean = false, //if true, images, fonts, etc. will be converted to base 64 URL, otherwise URL.createObjectURL is used
renderChanges: false, //enables experimental rendering of document changes (inserions/deletions)
renderHeaders: true, //enables headers rendering
renderFooters: true, //enables footers rendering
renderFootnotes: true, //enables footnotes rendering
renderEndnotes: true, //enables endnotes rendering
renderComments: false, //enables experimental comments rendering
renderAltChunks: true, //enables altChunks (html parts) rendering
debug: boolean = false, //enables additional logging
}): Promise

/// ==== experimental / internal API ===
// this API could be used to modify document before rendering
// renderAsync = parseAsync + renderDocument

// parse document and return internal document object
parseAsync(
document: Blob | ArrayBuffer | Uint8Array,
options: Options
): Promise

// render internal document object into specified container
renderDocument(
wordDocument: WordDocument,
bodyContainer: HTMLElement,
styleContainer: HTMLElement,
options: Options
): Promise
`

Thumbnails, TOC and etc.
------
Thumbnails is added only for example and it's not part of library. Library renders DOCX into HTML, so it can't be efficiently used for thumbnails.

Table of contents is built using the TOC fields and there is no efficient way to get table of contents at this point, since fields is not supported yet (http://officeopenxml.com/WPtableOfContents.php)

Breaks
------
Currently library does break pages:
- if user/manual page break is inserted - when user insert page break
- if application page break is inserted - could be inserted by editor application like MS word (ignoreLastRenderedPageBreak should be set to false)
- if page settings for paragraph is changed - ex: user change settings from portrait to landscape page

Realtime page breaking is not implemented because it's requires re-calculation of sizes on each insertion and that could affect performance a lot.

If page breaking is crutual for you, I would recommend:
- try to insert manual break point as much as you could
- try use editors like MS Word, that inserts break points

NOTE: by default ignoreLastRenderedPageBreak is set to true. You may need to set it to false, to make library break by break points

Status and stability
------
So far I can't come up with final approach of parsing documents and final structure of API. Only renderAsync function is stable and definition shouldn't be changed in future. Inner implementation of parsing and rendering may be changed at any point of time.

Contributing
------
Please do not include contents of ./dist` folder in your PR's. Otherwise I most likely will reject it due to stability and security concerns.
