parcel-reporter-gas-imports
🔥 Parcel plugin that enables bundling of Google App Script HTML.
This is the plugin for Parcel v2. The plugin for the first version can be found here.
📚 Introduction
If you've ever developed an add-on for Google's Office Suite with Google Apps Script,
then you'll know how inefficient it is to develop your add-on's UI.
This is because Google's Apps Script supports only .gs and .html files.
If you want to use CSS and JS, the only option is to create an HTML file and wrap
your CSS code inside <style> tag or your JS inside <script> tag and include
it in your UI using scriptlets.
This approach has serious flaws.
Parcel (nor any other modern JS bundler for that matter), doesn't recognize scriptlets <?!= ?>.
Because of this, it won't apply any code transformation to those files and won't bundle them.
Why is this approach bad?
-
🚫 CSS not prefixed (The UI breaks on some browsers) -
🚫 JS not transpiled (Usage of modern JS not possible) -
🚫 Code can't be split in modules -
💣 Large file sizes (Code not minified)
📦 Installation
# Installs the plugin and saves it as a development dependency
npm i parcel-reporter-gas-imports -D
🔌 Configuration
We need to create .parcelrc configuration file and add the plugin to reporters like this:
Syntax "..." instructs Parcel to apply the plugin on top of existing reporters
{
"extends": "@parcel/config-default",
"reporters": ["...", "parcel-reporter-gas-imports"]
}
☁️ Usage
The plugin allows you to include your JS and CSS just like you would normally do it in HTML:
# Example add-on UI files
src
├── index.html
├── style.css
└── script.jsindex.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
<link rel="stylesheet" href="style.css" />
</head>
<body>
<h1>Google Apps Script Sidebar</h1>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="script.js"></script>
</body>
</html>
🚀 Build
parcel build src/index.html
# Fully optimized project ready for deployment
dist
├── index.html
├── style.e308ff8e.css.html
└── script.75da7f30.js.html
