How to use it
- Shape your data like the sample data below; serve it as JSON from your server.
- Load the definition with getTemplate(id), or save the JSON below in your project.
- Change the company name, logo, seal and wording with [Open in the designer], then [Save] the JSON.
- Printing and PDF, Excel and HWPX export are already in the viewer toolbar.
import { getTemplate, createViewer } from '@freereportjs/core';
import '@freereportjs/core/styles.css';
const t = getTemplate('employment-certificate'); // a fresh copy each call
createViewer(document.getElementById('report'), {
definition: t.definition,
data: myData, // same structure as the sample data below
});Seals are generated from text in the data; to use a real seal image, set an image on the seal element in the designer. The default fonts are Nanum Gothic and Nanum Myeongjo.
