Angular Template

Angular-Like HTML Template Engine For NodeJS

Why do I need this? By unknown reason, I feel all server-side template engines are somewhat invasive. It looks like an odd language have been invaded HTML space. The only template I feel good about it is AngularJS, but it's all about client-side, not server-side part. If you are a big fan of AngularJS and you want to use AngularJS as a template engine, this node module will do the job.

This template converts the following one time binding expressions on the server-side;

1. inline expression
   e.g. {{ foo }}

2. ht-if attribute
   e.g., <div ht-if="foo">..</div>

3. ht-repeat attribute
   e.g., <li ht-repeat="el in list">..</li>
   e.g., <li ht-repeat="(k,v) in list">..</li>

4. ht-include attribute
   e.g., <div ht-include="'file.html'"></div>

Install

npm install angular-template

Usage

var htmlTemplate = require('angular-template');
htmlTemplate('{{foo}}', {foo:'Hello'}); //Hello

// or
var htmlTemplate = require('angular-template');
var path = "emails/template.html";
var options = {prefix:'ng'}; // so that ng-if, ng-repeat, ng-include would work
htmlTemplate(path, {name:'John'}, options);

Options

prefix: <string>, override default ht prefix with anything, typically ng to reuse angular templates
preprocess: <function>, enables you to modify your template before parsing it as HTML. E.g. You can remove some attributes with RegExp
includeDirs: <array of string>, a list of paths where to look for template
cache: <string>, specify cache key to avoid reading files from disk every time

Converting Angular-Like Expressions

This will convert the angular-like expressions into html.

1. Curly braces expression.

Assuming foo has the value of 123

    Input                                | Output
    -------------------------------------+---------------------------------
    {{foo}}                              | 123

2. ht-if attribute

Assuming foo has value true, and bar has value false

    Input                                | Output
    -------------------------------------+---------------------------------
    <p ht-if="foo">SHOW</p>              | <p>SHOW</p>    
    <p ht-if="bar">NO SHOW</p>           | <p></p>

3. ht-include attribute

Assuming foo.html has the following contents <b>file contents</b>

The input and output would like;

    Input                                | Output
    -------------------------------------+------------------------------------
    <p ht-include="'foo.html'"></p>      | <p>
                                         |   <b>file contents</b>
                                         | </p>

4. ht-repeat attribute

Assuming collection has the vaulue of {a:1, b:2, c:3, d:4, e:5}

    Input                                         | Output
    ----------------------------------------------+------------------------------------
    <ul>                                          | <ul>
       <li ht-repeat="(key, val) in collection">  |   <li> a : 1</li>
         {{key}} : {{val}}                        |   <li> b : 2</li>
       </li>                                      |   <li> c : 3</li>
    </ul>                                         |   <li> d : 4</li>
                                                  |   <li> e : 5</li>
                                                  | </ul>

Assuming collection has the vaulue of [1,2,3,4,5]

    Input                                         | Output
    ----------------------------------------------+------------------------------------
    <ul>                                          | <ul>
       <li ht-repeat="num in collection">         |   <li> 1 </li>
         {{num}}                                  |   <li> 2 </li>
       </li>                                      |   <li> 3 </li>
    </ul>                                         |   <li> 4 </li>
                                                  |   <li> 5 </li>
