engine

Template engine based on Lo-Dash template, but adds features like the ability to register helpers and more easily set data to be used as context in templates.

Install

Install with npm:

$ npm install --save engine

Usage

var Engine = require('engine');
var engine = new Engine();

engine.helper('upper', function(str) {
  return str.toUpperCase();
});

engine.render('<%= upper(name) %>', {name: 'Brian'});
//=> 'BRIAN'

API

Engine

Create an instance of Engine with the given options.

Params

• options {Object}

Example

var Engine = require('engine');
var engine = new Engine();

// or
var engine = require('engine')();

.helper

Register a template helper.

Params

• prop {String}
• fn {Function}
• returns {Object}: Instance of Engine for chaining

Example

engine.helper('upper', function(str) {
  return str.toUpperCase();
});

engine.render('<%= upper(user) %>', {user: 'doowb'});
//=> 'DOOWB'

.helpers

Register an object of template helpers.

Params

• helpers {Object|Array}: Object or array of helper objects.
• returns {Object}: Instance of Engine for chaining

Example

engine.helpers({
 upper: function(str) {
   return str.toUpperCase();
 },
 lower: function(str) {
   return str.toLowerCase();
 }
});

// Or, just require in `template-helpers`
engine.helpers(require('template-helpers')._);

.data

Add data to be passed to templates as context.

Params

• key {String|Object}: Property key, or an object
• value {any}: If key is a string, this can be any typeof value
• returns {Object}: Engine instance, for chaining

Example

engine.data({first: 'Brian'});
engine.render('<%= last %>, <%= first %>', {last: 'Woodward'});
//=> 'Woodward, Brian'

.compile

Creates a compiled template function that can interpolate data properties in "interpolate" delimiters, HTML-escape interpolated data properties in "escape" delimiters, and execute JavaScript in "evaluate" delimiters. Data properties may be accessed as free variables in the template. If a setting object is provided it takes precedence over engine.settings values.

Params

• str {string}: The template string.
• opts {Object}: The options object.
• escape {RegExp}: The HTML "escape" delimiter.
• evaluate {RegExp}: The "evaluate" delimiter.
• imports {Object}: An object to import into the template as free variables.
• interpolate {RegExp}: The "interpolate" delimiter.
• sourceURL {string}: The sourceURL of the template's compiled source.
• variable {string}: The data object variable name.
• returns {Function}: Returns the compiled template function.

Example

var fn = engine.compile('Hello, <%= user %>!');
//=> [function]

fn({user: 'doowb'});
//=> 'Hello, doowb!'

fn({user: 'halle'});
//=> 'Hello, halle!'

.render

Renders templates with the given data and returns a string.

Params

• str {String}
• data {Object}
• returns {String}

Example

engine.render('<%= user %>', {user: 'doowb'});
//=> 'doowb'
