diet-ect-fix

HTML template engine module for diet based on ect. The Fastest JavaScript template engine with embedded CoffeeScript syntax.

This is a fork of diet-ect

Adam appears to have abandoned Diet, and I'm sick of having to manually fix this every time I start a new Diet project.

This fork fixes 2 problems:

Actually able to render pages other than "index.html"
Sends a status code of 200 instead of 404 when serving pages

Anyway here's the README

{{ if this.page is 'home' :}}
	<h1>Users:</h1>
	<ul>
		{{for user in this.users :}}
			<li>{{-user.name}} is cool.</li>
		{{end}}
	</ul>
{{ else :}}
	<h1>404 Page not Found</h1>
{{ end }}

Install

npm install diet-ect-fix

Please note the new v1.0.x only works with diet >=v0.9.17

ECT:

You can learn to use ECT quickly with the Quick Syntax Guide below or in more detail on ECT's websites. Please note diet-ect by default uses differnt open and curly braces {{ and }}, while ECT by default uses uses <% and %>.

Usage

Server Setup

~/yourApp/index.js


// Initialize Server
var server = require('diet')    // Require Diet
var app = server() // Create App
app.listen(8000)   // Configure Domain

// Require ECT
var ect = require('diet-ect')({ path: app.path+'/static' })

// Load ECT as a global header
app.header(ect)

// Listen on GET /
// ECT is a global header so you can access it 
// from every route with the `$.html()` method
app.get('/', function($){
   // Set a template variable
   $.data.myVar = 'ect'
   
   // Now serve the html file 
   // by default: /your_app/static/index.html 
   // use the `root` config to change this
   $.html() 
})

Write Dynamic HTML

~/yourApp/static/index.html

<!DOCTYPE html>
<html>
    <head>
        <title>Hello World!</title>
    </head>
    <body>
        <h1>Hello World at {{-this.myVar}}</h1>
    </body>
</html>

Template Variables

You can access anything defined in the $ signal from your templates including:

$.query 	// in template {{ this.query }}
$.body 		// in template {{ this.body }}
$.params 	// in template {{ this.params }}
$.url 		// in template {{ this.query}}
$.data 		// in template {{ this }} data is a special variable

The $.data variable

The $.data object has a priority and will overwrite the variables from the signal.
The $.data variable is directly accessible like {{-this.myVar}} instead of {{-this.data.myVar}}.
The $.data object is also used by the $.json() response making APIs easier to build.

Custom file

By default $.html() will serve an index.html file relativ to the root config.

$.html('yourFile.html') // will serve /your_app/static/yourFile.html

You can change the file when you call $.html() by passing in an argument with a different path.

Config

You can use any config that ECT already has. These are the defaults with diet-ect:

require('diet-ect')({
	root : '/', 
	ext: '.html', 
	open: '{{', close: '}}',
	cache: true,
	watch: true,
	gzip: true
})

Quick Syntax Guide

Printing

Escaped Output

<h1>{{- this.title }}</h1>

Unescaped Output

<code>{{= this.source }}</code>

Decision Making

If

{{if this.is :}}
	then show this
{{end}}

If - Else

{{ if this.is :}}
	then show this
{{ else :}}
	otherwise show this
{{ end }}

If - Else If - Else

{{ if this.is :}}
	then show this
{{ else if this.otherwise :}}
	otherwise show this
{{ else :}}
	every other way show this
{{ end }}

Including

Let's say this is our project structure:

/views
....../html
............/header.html
............/home.html
............/about.html

And we would like to resue header.html in both home.html and about.html.

This is header.html:

<section>
	<a id="logo">A Wonderful Service</a>
</section>

And this is home.html:

{{ include 'header' }}
<h1>Welcome to my homepage</h1>
...

And this is about.html:

{{ include 'header' }}
<h1>About Me</h1>
...

Voala! You can use .html in the include string but it is not necessary. Please note if you define a new variable inside a template it will only be passed to included files if it was defined within the this variable.

Looping

Looping Through Array

The data:

$.data.letters = ['A', 'B', 'C']

The template:

{{for letter in this.letters :}}
	{{-letter}} <br>
{{end}}

The output:

A
B
C

Looping Through Object

The data:

$.data.capitals = { a: 'A', b: 'B', c: 'C' }

The template:

{{for key, value of this.capitals :}}
	{{-key}}: {{-value}} <br>
{{end}}

The output:

a: A
b: B
c: C

Please note if you would like to iterate over just the keys that are defined on the object itself, by adding a hasOwnProperty check to avoid properties that may be inherited from the prototype, use the own directive in the looping syntax like:

{{for own key, value of object :}}
	{{-key}}: {{-value}} <br>
{{end}}

Looping Through Array of Objects

The data:

$.data.grades = [
	{ student: 'Arnold', value: 'A+' }, 
	{ student: 'Billy', value: 'B+' }, 
	{ student: 'Carol', value: 'C-' }
];

The template:

{{for grade in this.grades :}}
	{{-grade.student}} received {{-grade.value}} <br>
{{end}}

The output:

Arnold received A+
Billy received B+
Carol received C-

Looping Through Array with Indexes

The data:

$.data.letters = ['A', 'B', 'C']

The template:

{{for value, index in this.letters :}}
	{{-index}}. {{-value}} <br>
{{end}}

The output:

1. A
2. B
3. C

Functions

Simple Function Declaration

{{ link = (url, text) -> }}
	<li><a href="{{- url }}">{{- text }}</a></li>
{{ end }}

<ul>
	{{-link '/', 'home'}}
	{{-link '/about', 'about'}}
	{{-link '/contact', 'contact'}}
</ul>

Using Local Template Variables

Please note you cannot access template variables that are created locally within the template unless it is defined as a property of the global context object this.

This IS working:

<!-- define GLOBAL template variable -->
{{this.preText = 'Learn more about '}}

{{ myFunction = (text) -> }}
	<li>{{- this.preText }} {{- text }}</li>
{{ end }}

<!-- call the function -->
{{-text 'football'}}
{{-text 'hockey'}}

This IS NOT working:

<!-- define LOCAL template variable -->
{{preText = 'Learn more about: '}}

<!-- create function -->
{{ myFunction = (text) -> }}
	<li>{{- preText }} {{- text }}</li>
{{ end }}

<!-- call the function -->
{{-text 'football'}}
{{-text 'hockey'}}

The `:`

As you can see the colon punctuation : is sometimes used and sometimes not. It can be confusing at the beginning but hopefully this will save you some time:

The : is only needed for if else-if else and for directives - for everything else you don't need it.

To learn more about the syntax check out ECT.js and CoffeeScript.
