Formally know as handlebars-midden

assemble-midden

Assemble Helper to create pretty/interactive data dumps using midden.

See the midden docs for a further explanation.

Install

npm install assemble-midden --save

Using with Assemble.js

Require assemble-midden into your assemblefile.js and register it as a helper.

var assemble = require('assemble');
var midden = require('assemble-midden');
 
var app = assemble();
 
// register midden as a helper
app.helper('midden', midden(true));

Midden has one config variable: isActive. This allows you to deactivate it when generating pages for a production environment. When inactive, it just returns an empty string. It might be used like so...

/* assuming var environment was set earlier */
app.helper('midden', midden(environment==='development'));

For midden to work, you also need to include it's styles and client-side code. You can find those in node_modules/midden/dist/[styles, js].

Here's how you might add them to your css and script tasks.

Stylesheets

There are three stylesheets available: midden.scss, midden.css and midden.min.css. Here's how you might add midden.scss to a SASS task.

/* using sass and autoprefixer gulp plugins */
var sass = require('gulp-sass');
var autoprefixer = require('gulp-autoprefixer');
 
/* create an array of paths to outside stylesheets */
var styleIncludes = [
  'node_modules/midden/dist/styles/'
];
app.task('css', function () {
  return app.src('src/scss/app.scss')
    .pipe(sass({includePaths: styleIncludes})
    .pipe(autoprefixer())
    .pipe(app.dest('build/css'));
});

Then in your app.scss file...

/* Need to include extension so that SASS doesn't include the wrong file */
@import "midden.scss";

Client-Side JavaScript

If you're using browserify to process your Javascript, just require it in your main JS file.

require('midden/dist/js/midden-client.js');

On page load, it will look for midden elements to attach event handlers to.

Within your Handlebars Files

Wherever you need to inspect a context value just pass it to the helper.

{{midden "view.data"}}

Load that page from your destination directory and you should see something like this...

Tips for Use

• When passed large objects, midden can generate large amounts of HTML. If you're interested in just a small part of that object then specify it in your call to midden.
• The midden client-side code uses methods not supported by IE versions 9 and earlier (which shouldn't be a problem in a development only environment). Just in case you're using an older IE you might have to install a shim like classList.

Customizing Styles

The dist/styles/midden.scss file uses over-writable default values for colors, etc. See the file for a list of values.

Feel free to submit issues or pull requests for assemble-midden or midden. Questions on use can also be submitted to the issue queue.

There's a suite of unit tests. mocha test/*-spec.js

Midden also has a gulp file for generating client-side assets and integration testing. gulp default will spin up a server on port 8000. There, you can demo midden.
