Common page layouts and partials.

Installation

npm install [--save] hmpo-templates

Setup

Install hmpo-govuk-template, hogan-express-strict and express-partial-templates as part of your project.

var app = require('express')();

require('hmpo-govuk-template').setup(app);

app.set('view engine', 'html');
app.use(require('hmpo-templates'));
app.engine('html', require('hogan-express-strict'));
app.use(require('express-partial-templates')(app));

Basic usage

my-page.html

{{< hmpo-layout}}
    {{$pageTitle}}...page title...{{/pageTitle}}

    {{$header}}
        <h1>...heading...</h1>
    {{/header}}

    {{$content}}
        <p>...intro content...</p>
        {{< hmpo-partials-form}}
            {{$form}}
                ...form inputs...
                ...form submit button...
            {{/form}}
        {{/ hmpo-partials-form}}
    {{/content}}
{{/ hmpo-layout}}

Templates

The templates are added to res.locals with hmpo as a prefix to the template names.

Layout:

• maincontent (sets maincontent-left as the default and provides a block to override)
• maincontent-left
• maincontent-right
• maincontent-full
• flash-card

Partials:

• analytics
• gtm
• gtm-noscript
• back-link
• back
• betatag
• body-end
• cookies
• error-summary
• form
• head
• new-window
• sidebar
• warning

Changing a page layout

Create layout.html in your views directory.

{{< hmpo-layout}}
    {{$pageTitle}}...page title...{{/pageTitle}}

    {{$main-content}}
        {{< hmpo-partials-maincontent-right}}
            {{$header}}...heading...{{/header}}
            {{$content}}...content...{{/content}}
        {{/ hmpo-partials-maincontent-right}}
    {{/main-content}}
{{/ hmpo-layout}}

This changes the main page layout to maincontent-right. In your custom pages you can now inherit from layout.html.

Compatibility

Use with hmpo-template-mixins for form inputs and view formatters. When used with hmpo-form-wizard you'll get a validation summary appearing at the top of your page when a form error occurs.

Google Analytics Classic

To enable Google Analytics tracking expose a GA ID as res.locals['ga-id'].

Page views and form validation error events will be sent to GA.

Events contained in the array res.locals.gaevents will be fired on page view, for instance:

res.locals.gaevents = [
    {
        gaCategory: 'Category',
        gaAction: 'Action',
        gaLabel: 'Label',
        gaValue: 42
    }
];

Google Tag Manager

To enable Google Tag Manager expose GTM settings as:

res.locals.gtm = {
    id: 'GT-XXXXXX',
    preview: 'env-1',
    auth: 'abcdefg'
};

For production environments only an ID is required.

Page views and form validation error events will be sent to GTM.

Events contained in the array res.locals.gaevents will be fired on page view, for instance:

res.locals.gaevents = [
    {
        gaEvent: 'My Event', // defaults to 'Custom Event'
        gaCategory: 'Category',
        gaAction: 'Action',
        gaLabel: 'Label',
        gaValue: 42
    }
];

Note: Enabling Google Tag Manager will disable Google Analytics Classic
