Certificate Template Parser

This is a cli application that parses html files into json certificate templates.

Getting Started

To run this program, you should already have NodeJs installed.

Install all dependencies by running

npm install

Overview

The essence of this application is to simplify the process of generating certificate templates. This is done by parsing a html file containing the desired template.

Creating the Html file

To begin designing a template, it is advised that you start from the starter file provided i.e starter.html. You can add texts and elements by following the instructions below

Texts

A text object refers to anyform of text that is on a certificate. Texts could be attributes or hard text values. Attributes will get replaced by the data from the certificate object e.g a name attribute would get replaced by the name of the certificate holder.

<!-- Add Texts  -->
<h2 id="text-8">Lorem Ipsum has been the industry.</h2>

<!-- Add Texts that are attributes   -->
<h2 id="text-10" data-attribute="date">{{date}}</h2>

Texts should be created using "h2" tags. There's no hard reason for this except when the json is parsed back into a template, a h2 tag is used to represent the text. If a text is an attribute, the h2 tag should contain data-attribute="<enter_attribute>" as seen above. When a text is an attribute, the innerText wouldn't be taken into consideration. As a result the example above could be rewritten as

...

<!-- Add Texts that are attributes   -->
<h2 id="text-10" data-attribute="date">Anything you want</h2>

Another important thing to note is that all texts should have an id that begins with text- followed by any random string

Elements

A element object refers to any form of image that is on a certificate that isn't the background image. Texts could be replaced by the users logo by specifying the data-logo with any data inside. The image will get replaced by the logo from the user.

<!-- Add elements  -->
<img src="https://somesource" alt="" id="#element-1" />

<!-- Add elements that would be replaced by the logo  -->
<img src="https://somesource" alt="" id="#element-1" data-logo="true" />

Elements should be created using "img" tags. The src of the image tags should be live links to where the logo image

Preview

Usage: node index preview [options] filename

Generates a preview of the json certificate template

Arguments: filename path to json file

Options: -o, --output output Name of output pdf file (default: "output.pdf") -h, --help display help for command
