minifyfromhtml
This little helper minifies scripts and css starting from an html file.
What it is
I am making a js
widget, like a map, or a calendar field or something. This is the index.html
I use while developing the widget:
<!DOCTYPE html>
<html lang="en">
<head>
<title>example page</title>
<script src="somelib.js"></script>
<script src="someotherlib.js"></script>
<script src="awesomelib.js"></script>
<script src="spectacularlib.js"></script>
<script src="app.js"></script>
<link rel="stylesheet" type="text/css" href="some.css" />
<link rel="stylesheet" type="text/css" href="app.css" />
</head>
<body>
<div id="widget"></div>
<script>
myapp(document.getElementById('widget'));
</script>
</body>
</html>
I am not using a framework like angular or react. I am coding along in app.js
, and add libraries as I need them to index.html
.
Then comes a time I want to distribute my widget to the world. To do that, I would like to
- minify all referenced js files in index.html
- minify all css files
so that users of my widget can just include widget.js
and widget.css
and be good to go.
Is there something I can use that does that for me with minimal hassle? Something like
$ magictool index.html
- nice html you have. let me parse that and see what I need to do...
- oh, you have somelib.js. let me minify that for you and put it in dist.js
- oh, you have someotherlib.js. let me minify that for you and put it in dist.js
- oh, you have awesomelib.js. let me minify that for you and put it in dist.js
- oh, you have spectacularlib.js. let me minify that for you and put it in dist.js
- oh, you have app.js. let me minify that for you and put it in dist.js
- oh, you have some.css. let me minify that for you and put it in dist.css
- oh, you have app.css. let me minify that for you and put it in dist.css
! dist.js and dist.css created!
that reads index.html
and creates a dist.js
and dist.css
.
the magictool is minifyfromhtml.
Quickstart
npm i -g minifyfromhtml
minifyfromhtml --js=dist.js --css=dist.css < index.html
=>
some.css -> dist.css
app.css -> dist.css
somelib.js -> dist.js
someotherlib.js -> dist.js
awesomelib.js -> dist.js
spectacularlib.js -> dist.js
app.js -> dist.js
