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 🙏

Readme

ng-loader

ng-loader is a loader for Webpack that can transform *.ng files into AngularJs Components.

Note: [email protected] had a different purpose than version 2.*, it was currently migrated to ng-module-loader.

What is Webpack?

webpack is a tool to build JavaScript modules in your application. To start using webpack from its cli or api, follow the Installation instructions. webpack simplifies your workflow by quickly constructing a dependency graph of your application and bundling them in the right order. webpack can be configured to customise optimisations to your code, to split vendor/css/js code for production, run a development server that hot-reloads your code without page refresh and many such cool features. Learn more about why you should use webpack.

Understanding Loaders

Loaders are transformations that are applied on a resource file of your application. They are functions (running in Node.js) that take the source of a resource file as the parameter and return the new source. Learn more about loaders.

Install

npm install --save-dev ng-loader 

Usage

Use the loader either via your Webpack config.

Via webpack config (recommended)

module.exports = {
  module: {
    rules: [
      {
        test: /\.ng$/,
        use: [ 'ng-loader' ]
      }
    ]
  }
}

Passing parameters:

	{
        test: /\.ng$/, 
        use: ['ng-loader?map=false']
    }

Angular Component

In AngularJS, a Component is a special kind of directive that uses a simpler configuration which is suitable for a component-based application structure.

This makes it easier to write an app in a way that's similar to using Web Components or using the new Angular's style of application architecture.

Advantages of Components:

  • simpler configuration than plain directives
  • promote sane defaults and best practices
  • optimized for component-based architecture
  • writing component directives will make it easier to upgrade to Angular

You can see the full documentation here.

The *.ng file

A *.ng file is a custom file format that uses HTML-like syntax to describe a angular component. Each *.ng file consists of three types of top-level language blocks: <template>, <script> and <style>:

<!-- ./src/components/my-component.ng -->
<template>
    <h1 class="ui header">
        {{ $ctrl.description }}
    </h1>
</template>

<script>
    export default {
        controller(){
            this.description = 'A AngularJs Component!'
        }
    }
</script>

<style lang="sass">
    @import '~semantic-ui';
</style>

ng-loader will parse the file, extract each language block, pipe them through other loaders if necessary, and finally assemble them back into a CommonJS module whose module.exports is a AngularJs Component options object.

Language Blocks

<template>

  • Default language: html.

  • Each *.ng file can contain at most one <template> block at a time.

  • Contents will be extracted as a string and used as the template option for the compiled AngularJs Component.

<script>

  • Default language: js (ES2015 is supported automatically if babel-loader or buble-loader is detected).

  • Each *.ng file can contain at most one <script> block at a time.

  • The script is executed in a CommonJS like environment (just like a normal .js module bundled via Webpack), which means you can require() other dependencies. And with ES2015 support, you can also use the import and export syntax.

    // tag script inside ng file ./src/components/my-component.ng
    exports default {
        controller () {
            this.description = 'A AngularJs Component';
        }
    };

Registering your component:

import * as angular from 'angular';

import myComponent from './components/my-component.ng';

angular.module('app', []).component('myComponent', myComponent);

You can also return an array with the component data. The first item represents the component name and the second component options.

    // tag script inside ng file ./src/components/my-component.ng
    exports default ['myComponent', {
        controller: () => {
            this.description = 'AngularJs';
        }
    }];

and register as follows

import * as angular from 'angular';

import myComponent from './components/my-component.ng';

angular.module('app', []).component.apply(this, myComponent);

// ES2015
// .component(...myComponent)

<style>

  • Default Language: css;
  • Multiple <style> tags are supported in a single *.ng file;
  • By default, contents will be extracted and dynamically inserted into the document's <head> as an actual <style> tag using style-loader;

The component

<my-component></my-component>

Hot Reload

This feature is provided by ng-hot-reload-api

Syntax Highlighting

You can treat *.ng files as HTML in your editor.
