Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

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

  • 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}
