generating ﬁles static ﬁles data templates requests browsers

Templating Engines code express in

var compiled = _.template("hello: <%= name %>"); compiled({name: 'patrick'}); =>
"hello: patrick"

var compiled = Handlebars.compile("hello: {{ name }}”); compiled({name: 'patrick'}); =>
"hello: patrick"

handlebars abstractions top level template partials helpers

multiple environments http://template-demo.divshot.io/

design process Data templates DOM populate render improve data improve
templates ﬁles browser

entering JavaScript var Handlebars = require(‘handlebars’); $ npm install handlebars
// fetch handlebars with node package manager: // require in .js scripts

build.js -> page var Handlebars = require('handlebars'); var helpers =
require('./helpers'); var partials = require('./partials'); var templates = require(‘./templates’); ! var fs = require(‘fs'); // for working with files ! // initial data var creatives = JSON.parse(fs.readFileSync(‘./creatives.json')); ! // assemble templates var rendered = Handlebars.templates.profiles( {creatives: creatives.shots} );

simple build $ node build.js

build automation partials.js: handlebars -c handlebars -p -f partials.js ./partials/*
! templates.js: handlebars -c handlebars -f templates.js ./templates/* ! all: partials.js templates.js node build.js $ make -B all $ vim Makefile

Static ListView Example

Top-level template <h2>Profiles</h2> ! {{#creatives}} {{>profile}} {{/creatives}}

cURL data from e.g. dribbble.com [{ id: 1684751, title: 'Overview',
description: '<p>I\'ve been working on this in the little spare time that I have these days ;)</p>', height: 600, width: 800, likes_count: 124, comments_count: 6, rebounds_count: 0, url: 'http://dribbble.com/shots/ 1684751-Overview', short_url: ‘…’ }]

include helpers var Handlebars = require('handlebars'); ! Handlebars.registerHelper('html5', function(main) {
var html = '\ <!DOCTYPE html> \ <html> \ <head> \ <meta charset="utf-8"> \ <meta http-equiv="X-UA-Compatible" content="IE=edge"> \ <title>voki.me</title> \ </head> \ <body>'; ! return html + main.fn(main.data.root) + '</body></html>'; }); ! module.exports = Handlebars;

generate full page {{#html5}} ! <h2>Profiles</h2> ! {{#creatives}} {{>profile}} {{/creatives}}
! {{/html5}}
