[Deprecated] carbone-render

Note: This package has been deprecated and will no longer be receiving support updates.

Library to generate a document from an existing template and JSON data. This is a wrapper around carbone, please refer to their documentation for more detail.

Prerequisites

This library will require LibreOffice installed to do pdf generation.

Installation

npm i @bcgov/carbone-render

Usage

const carboneRenderer = require('@bcgov/carbone-render');

startFactory

Optional call to start up the carbone python converter. This is recommended to call on the start of your application. Otherwise, the first call to render will take longer as it starts the converter in the background.

carboneRenderer.startFactory();

fileTypes

Return a dictionary of allowable file conversions. Convert to pdf is always allowed.

const allowedConversions = carboneRenderer.fileTypes;

Returns dictionary
