SDEJS

A Template fork from ejs and then modify to fit with seedit

Installation

$ npm install sdejs

Features

see ejs version 0.8

Example

Try out a live example now

Usage

sdejs.compile(str, options);
// => Function

sdejs.render(str, options);
// => str

Options

• cache Compiled functions are cached, requires filename
• filename Used by cache to key caches
• scope Function execution context
• debug Output generated function body
• compileDebug When false no debug instrumentation is compiled
• client Returns standalone compiled function
• open Open tag, defaulting to "<%"
• close Closing tag, defaulting to "%>"
• blockpath The block files absolute path,must config it

• •             All others are template-local variables

Includes

Includes are relative to the template with the include statement, for example if you have "./views/users.ejs" and "./views/user/show.ejs" you would use <% include user/show %>. The included file(s) are literally included into the template, no IO is performed after compilation, thus local variables are available to these included templates.

<ul>
  <% users.forEach(function(user){ %>
    <% include user/show %>
  <% }) %>
</ul>

Custom delimiters

Custom delimiters can also be applied globally:

var sdejs = require('sdejs');
ejs.open = '{{';
ejs.close = '}}';

Which would make the following a valid template:

<h1>{{= title }}</h1>

Filters

EJS conditionally supports the concept of "filters". A "filter chain" is a designer friendly api for manipulating data, without writing JavaScript.

Filters can be applied by supplying the : modifier, so for example if we wish to take the array [{ name: 'tj' }, { name: 'mape' }, { name: 'guillermo' }] and output a list of names we can do this simply with filters:

Template:

<p><%=: users | map:'name' | join %></p>

Output:

<p>Tj, Mape, Guillermo</p>

Render call:

sdejs.render(str, {
    users: [
      { name: 'tj' },
      { name: 'mape' },
      { name: 'guillermo' }
    ]
});

Or perhaps capitalize the first user's name for display:

<p><%=: users | first | capitalize %></p>

Filter list

Currently these filters are available:

• first
• last
• capitalize
• downcase
• upcase
• sort
• sort_by:'prop'
• size
• length
• plus:n
• minus:n
• times:n
• divided_by:n
• join:'val'
• truncate:n
• truncate_words:n
• replace:pattern,substitution
• prepend:val
• append:val
• map:'prop'
• reverse
• get:'prop'

Adding filters

To add a filter simply add a method to the .filters object:

ejs.filters.last = function(obj) {
  return obj[obj.length - 1];
};

Layouts

Currently EJS has no notion of blocks, only compile-time includes, however you may still utilize this feature to implement "layouts" by simply including a header and footer like so:

<% include head %>
<h1>Title</h1>
<p>My page</p>
<% include foot %>
