This module injects meta tags between markers placed in an html file or removes code between markers. It can take a json file which will be transformed to strings and injected. It removes code between markers so you can for example remove livereload code which is not needed in a production environment. It can also inject the current git commit hash into the HTML as a comment so it is easily visible which commit is currently deployed.

This module was written in ES6 and requires node >= 4.0.0.

Usage

Place the markers in your html file to inject or remove code:

   <!DOCTYPE html>
   <html>
   <head>
     <title>Home</title>
     <meta name="viewport" content="width=device-width, initial-scale=1">

     <!-- inject:meta -->
     <meta name="devmeta" content="This meta will be replaced">
     <!-- endinject -->

   </head>
   <body>
        content
   </body>
   </html>
   <!-- inject:git-hash -->

The meta tags will be injected between the markers and the meta that are already there will be removed.

Options:

-h, --help             output usage information
-V, --version          output the version number
-i, --input <input>    Input file
-o, --output <output>  Output file (defaults to input when omitted)
-r, --remove <remove>  Remove condition
-H, --hash             Inject git hash of current commit

Examples

Given a meta.json file:

{
	"meta": [{
			"name": "testmeta",
			"content": "Example content"
		},{
			"name": "testmeta2",
			"content": "Example content 2"
		}]
}

injectmeta -i index.html -o dist/index.html -m meta.json

will result in the file dist/index.html:

   <!DOCTYPE html>
   <html>
   <head>
     <title>Home</title>

        <meta name="testmeta" content="Example content">
        <meta name="testmeta2" content="Example content 2">

   </head>
   <body>

   </body>
   </html>

Notice that the code

     <!-- remove:production -->
     <script src="http://localhost:35729/livereload.js?snipver=1"></script>
     <!-- endremove -->

has been removed.

The comment

    <!-- inject:git-hash -->

has been replaced by the git hash of the current commit.
