This framework simplifies the task of writing code for Roll20 character sheets. It aims to provide an easier interface between the html and sheetworkers with some minor css templates.

const path = require('path');
const fs = require('fs/promises');
const kStatus = require('./kStatus');

const renderTemplates = async (destination,sourceDir) => {
  if(!sourceDir) return;
  return Promise.all(
    Object
      .entries(destination)
      .map(async([destDir,files]) =>{
        const readmeTemplatePath = path.resolve(sourceDir,'readme.md');
        const jsonTemplatePath = path.resolve(sourceDir,'sheet.json');
        let readme = '';
        let sheetJSON = {};
        const sheetDestPath = path.resolve(destDir,'sheet.json');
        let origJSON;
        try {
          origJSON = await fs.readFile(sheetDestPath,'utf8')
            .catch(e => e);
        } catch (error) {

        }
