This plugin is intended to work with PostHTML. It will allow you to keep HTML head elements - title, script, link, base and meta - in a separate JSON file:
{
"meta": [
{
"charset": "utf-8"
},
{
"http-equiv": "X-UA-Compatible",
"content": "IE=edge"
},
{
"name": "description",
"content": "A front-end template that helps you build fast, modern mobile web apps."
},
{
"name": "viewport",
"content": "width=device-width, initial-scale=1"
}
],
"title": "Web Starter Kit",
"link": [
{
"rel": "manifest",
"href": "manifest.json"
},
{
"rel": "icon",
"sizes": "192x192",
"href": "images/touch/chrome-touch-icon-192x192.png"
}
],
"script": [
{
"src": "//cdn.polyfill.io/v1/polyfill.min.js"
}
],
"base": [
{
"href": "/"
}
]
}A custom tag, which signifies where the HTML head elements should be inserted during the build process, needs to be placed in the document head:
<!doctype html>
<html lang="en">
<head>
<posthtml-head-elements></posthtml-head-elements>
<!-- Add to homescreen for Chrome on Android -->
<meta name="mobile-web-app-capable" content="yes">
<meta name="application-name" content="Web Starter Kit">This is then configured like below if you are using gulp-posthtml. Please read the PostHTML GitHub page for plugin configuration guidelines.
var posthtml = require('gulp-posthtml');
var gulp = require('gulp');
var jsonPath = '/data/posthtml-head-elements.json';
gulp.task('posthtml', function() {
var plugins = [
require('posthtml-head-elements')({headElements: jsonPath})
];
return gulp.src('/app/index.html')
.pipe(posthtml(plugins))
.pipe(gulp.dest('/build/'));
});Note that the HTML head elements are inserted into the document in the spatial order they are laid out - from top to bottom
It is possible to mix the head elements, but the JSON syntax requires a unique key. Therefore, if you are using more than one head element, place an underscore immediately afterwards.
An example of a JSON file with multiple head elements:
{
"meta": [
{
"charset": "utf-8"
},
{
"http-equiv": "X-UA-Compatible",
"content": "IE=edge"
},
{
"name": "description",
"content": "A front-end template that helps you build fast, modern mobile web apps."
},
{
"name": "viewport",
"content": "width=device-width, initial-scale=1"
}
],
"title": "Web Starter Kit",
"link": [
{
"rel": "manifest",
"href": "manifest.json"
}
],
"meta_1": [
{
"name": "mobile-web-app-capable",
"content": "yes"
},
{
"name": "application-name",

}
],
"link_1": [
{
"rel": "icon",
"sizes": "192x192",
"href": "images/touch/chrome-touch-icon-192x192.png"
}
],
