cartero-node-hook

A hook for cartero implemented in Node.js.

Installation

npm install cartero-node-hook

Usage

var hook = require( 'cartero-node-hook' );
var path = require( 'path' );
 
var h = hook( path.join( __dirname, 'static/assets' ) );
 
// get the html tags to load the js and css assets associated with
// an entry point for which cartero was run.
h.getTagsForEntryPoint( entryPointPath, function( err, tags ) {
  // tags.script is a string of <script> tags
  // tags.style is a string of <link> tags
} );

Using Express? cartero-express-midddleware automatically populates res.locals with the script and link tags for the view being rendered.

API

h = hook( outputDirPath, options );

outputDirPath is the absolute path to your cartero output directory, as passed into cartero at build time. options may contain:

• outputDirUrl (default: '/') - the base url corresponding to the cartero output directory relative to the domain root.

• appRootDir (default: undefined) - The root directory of your application. (You generally only need to supply this option if the directory structure of the system on which your application is being run is different than of the system on which cartero was run.)

• cache (default: true) - whether or not to cache meta data. Set to false in dev mode so that you don't need to restart your application when assets are changed.

h.getTagsForEntryPoint( entryPointPath, cb )

Get the HTML tags to load the script and style assets for a JavaScript entry point.

h.getTagsForEntryPoint( '/usr/rotunda/my-app/views/page1/page1.js', function( err, tags ) {
    // tags.script is a string of <script> tags
    // tags.style is a string of <link> tags
} );

h.getAssetsForEntryPoint( entryPointPath, cb )

Returns a hash of asset paths keyed by asset type. All paths are relative to the output directory.

h.getAssetsForEntryPoint( '/usr/rotunda/my-app/views/page2/page2.js', function( err, assets ) {
    console.log( assets.style );  // array of paths (ex: [ 'url/to/bundle.css' ])
}

h.getAssetUrl( assetPath )

Returns the url of the asset with the absolute path assetPath using metaData.json assetMap

h.getAssetUrl( '/usr/rotunda/my-app/views/page2/photo.png') //'url/to/package/img/photo_sha.png'

Change log

v0.3.2

• Add option to support set the crossorigin attribute in script tag.

v3.0.0

• Changed getAssetUrl implementation (looks in asset data in the metaData created by cartero)

v2.0.0

• Changed getParcelTags to getTagsForEntryPoint and getParcelAssets to getAssetsForEntryPoint

v1.0.0

• Removed parcelDirPath argument from initializer. (No longer needed since parcel paths are now stored in meta data as absolute paths.) Note this is an API change that will affect all users. Just get rid of the first argument to the intializer and you'll be good to go.
• cacheParcelData option changed to just cache
• Other assorted tweaks to work with new metaData.json file from cartero v3.0.0. You must use cartero >= v3.0.0 with this hook.

v0.3.1

• First version in this change log.
