instapack v6.0.0-beta5

instapack

All-in-one web app client project compiler using TypeScript and Sass! :package: :rocket:

Install

npm install -g instapack

If you encounter errors during installation, try:

• Running install as Administrator or using elevated privileges (sudo).

• Or clear the npm cache: npm cache clean --force then: npm install -g instapack --no-optional

• Or downgrade to npm 4 to avoid buggy npm 5: npm install -g npm@4

• Or use Yarn instead: yarn global add instapack

Quick Start Guide

cd E:\VS\MyWebApp
ipack new empty
ipack

Programmable API is also provided if you wish to integrate instapack into your very own build script:

const instapack = require('instapack');

let ipack = new instapack();
ipack.build('all');

Practical guides can be read in books folder.

System Requirements

Currently supported Node.js is the latest version 8 LTS.

When using Visual Studio 2017 (Update 2 or above), install the latest TypeScript SDK for Visual Studio 2017.

When using Visual Studio 2015 (Update 3 or above), install the latest TypeScript SDK for Visual Studio 2015.

If using the latest Visual Studio Code, it should come with the latest TypeScript support out of the box.

Features

• Hyper-opinionated web app client project builder with near-zero configurations. It just works. :sparkling_heart:

• Built-in new project scaffold tool. :gift:

• Rich debugging experience using DevTools: set breakpoints, view variable values, and step into the TypeScript source code directly in the browser! :mag:

Design Goals

• Lower the barrier of entry for developing a modern web app. :angel:

• Introduce structure to the app client source code. :office:

• Improve source code quality and maintainability with type hints and compile-time checks. :eyeglasses:

• Enforce best practices when building apps, which may significantly impact page load time. (e.g. bundling and minification) :airplane:

• Unify team build system across multiple projects, for any frameworks. :fist:

• Blur the boundary between design time and coding time using lightning fast watch + dev compilation mode. :zap:

But... Why?

Recently every hecking framework on this planet :earth_asia: has their own CLI, but only few are able to support TypeScript out of the box. So most people gave up on TypeScript right off the bat... :broken_heart:

instapack is an initiative to develop a command line tool for compiling most apps developed using mainstream JavaScript frameworks, with a :lemon: twist: It can easily build an app written in TypeScript with minimal or no further configurations!

Powered by webpack, instapack effortlessly devours modules written using modern JS standards (ES Harmony, CommonJS, AMD, UMD) and is capable of importing HTML templates out of the box. instapack is battle-tested :hocho: and is designed to cover 99.99% normal use cases when developing a modern web app.

With this powerful tool, you can save time :watch:, save precious SSD space :space_invader:, and save yourself from the pain of manually maintaining project build scripts! :coffee:

How does it work?

Out of the box, these files will be used as the entry points:

• client/js/index.ts, compiled to wwwroot/js/ipack.js

  • Simply include this file in your HTML using <script> at the bottom / before so the browser can render the page while loading the script.

  • Anything you import from node_modules will be split to ipack_modules.js, please include this file in your HTML just before ipack.js

• client/css/index.scss, compiled to wwwroot/css/ipack.css

  • Also include this file in your HTML using <link> on the top / before </head> so the browser can style and render the page as it loads.

  • The Sass language compiler service has been configured to enable @import from node_modules!

  • Spiced with :hot_pepper: PostCSS AutoPrefixer for applying CSS vendor-prefixes automatically!

• Concatenate files listed in package.json. Usually the output file will be included in the HTML before ipack.js. Read more below.

Commands

You may use instapack or ipack or ipk to invoke the command line interface.

new template

Scaffolds a new instapack project into your existing app folder where the command line is invoked. The following templates are available:

• empty when you need a minimal clean slate. Use this template to author new templates!

• vue when you want to develop a web app with Vue.js and Bootstrap 4. (Includes aspnet-validation for ASP.NET MVC client-side validation.)

• react when you want to develop a web app with React and Semantic UI.

• inferno when you want to develop a web app with Inferno and Bootstrap 4.

• angularjs when you need to develop a legacy web app with AngularJS 1.7, jQuery, and Bootstrap 3. (Includes jquery-validation-unobtrusive for ASP.NET MVC client-side validation.)

If no template parameter is provided, vue will be chosen.

build project

Performs compilation against selected project type. Available projects: all, js, css and concat. If no project parameter is provided, all will be chosen.

In addition, build flags are available:

• -w or --watch enables incremental compilation on source code changes.

• -d or --dev disables outputs minification for fast build!

• -u or --uncharted disables source maps. (Slightly improves build speed)

• -a or --analyze generates module size report analysis.html next to the JS build output.

You can combine multiple build flags, for example: ipack -dw = dev + watch mode for massive productivity gainz! :muscle:

clean

Remove files in the output folders.

Configuration

instapack puts configuration inside package.json to reduce project files clutter. For example, this is the included package.json with vue template:

{
  "name": "aspnet",
  "version": "1.0.0",
  "private": true,
  "instapack": {
    "output": "wwwroot",
    "concat": {
      "vendor": [
        "es6-promise/dist/es6-promise.auto",
        "bootstrap.native/dist/polyfill",
        "bootstrap.native/dist/bootstrap-native-v4"
      ]
    },
    "alias": {
      "vue": "vue/dist/vue.common"
    }
  },
  "dependencies": {
    "@types/requirejs": "^2.1.31",
    "aspnet-validation": "^0.0.4",
    "axios": "^0.18.0",
    "bootstrap": "4.0.0",
    "bootstrap.native": "^2.0.21",
    "es6-promise": "^4.2.4",
    "font-awesome": "^4.7.0",
    "linq": "^3.0.9",
    "moment": "^2.20.1",
    "noty": "^3.2.0-beta",
    "tslib": "^1.9.0",
    "vex-js": "^4.0.1",
    "vue": "^2.5.13",
    "vue-class-component": "^6.2.0"
  }
}

• input allows setting the input folder name. By default, it is set to client

• output allows setting the output folder name. By default, it is set to wwwroot

• jsOut allows setting the JS output file name. By default, it is set to ipack.js

• cssOut allows setting the CSS output file name. By default, it is set to ipack.css

• alias allows overriding module import calls from all files, including dependencies. Read more: https://webpack.js.org/configuration/resolve/

  • This was needed because the default Vue.js package main file points to runtime-only build, which does not include the HTML template compiler... To avoid using this, read the template configuration below.

• externals allows rewriting module import calls from all files, including dependencies, to globally exposed objects via window object. Read more: https://webpack.js.org/configuration/externals/

For example:

{
  "instapack": {
    "externals": {
      "jquery": "$"
    }
  }
}

converts this...

import jQuery from 'jquery';

into this...

const jQuery = window["$"];

so CDN can be used! :tada:

<script src="https://unpkg.com/jquery@3.2.1/dist/jquery.js"></script>

• concat allows packing browser libraries to be consumed directly from <script src="..."> rather than as a module.

  • The file names will be resolved node-style (but NOT their contents), which allows concatenating packages downloaded from npm to be bundled, minified, and then placed into the output JS folder.

  • Use concatenation for libraries that cannot be imported / do not need to be imported (for example, jQuery plugins). This hybrid approach allows greater compatibility with older libraries, while enjoying the rich development experience using TypeScript.

  • For consuming the libraries within the TypeScript app code, load them before bundle.js then use the externals module configuration. (You may use CommonJS syntax to import the module; read more below...)

  • Alternatively, reference the library objects directly from the window object (e.g. window['$']).

concat configuration example: (produces vendor.js bundle)

{
  "instapack": {
    "concat": {
      "vendor": [
        "jquery",
        "bootstrap",
        "jquery-validation",
        "jquery-validation-unobtrusive",
        "./client/lib/my-old-jquery-plugin"
      ]
    }
  }
}

Module Systems

• Use ES Harmony module syntax to import and export other .ts / .tsx files in the project or JavaScript modules from node_modules installed via npm or yarn. This technique allows the ease of development using intellisense for modules with type definitions:

  • The module has "typings": "something.d.ts" in its package.json. For example: vue, linq

  • The module has @types installed. For example, react and @types/react

import List from 'linq';

• You may also use CommonJS module syntax to import JavaScript modules from node_modules installed via npm, but you will NOT get intellisense (module will be imported as any data type).

let $ = require('jquery');

• Use CommonJS module syntax to import non-TypeScript modules (files with .js extension). This technique is NOT recommended but allows interoperability between the TypeScript project and older codes written in plain JavaScript:

require('./something');

• Use CommonJS syntax to easily import an HTML template as a simple string (type-hinted). This technique allows working with libraries or frameworks relying on HTML-based templates such as AngularJS, mustache.js, Handlebars.js, Ember.js, and Vue.js. The input file will be minified and then stringified.

let template = require('./mytemplate.html') as string;

• Use CommonJS syntax to import a static JSON file content as a JavaScript module object. This import can be type-hinted for convenience.

let something = require('./something.json') as Something;

• In pursuit of greater app performance, instapack allows Ahead-of-Time (AoT) compilation of HTML templates using Vue.js render syntax. HTML files with special file extension .vue.html will be compiled into an object to be passed into Vue Component decorator as parameters:

import Vue from 'vue';
import Component from 'vue-class-component';
import { render, staticRenderFns } from './MyComponent.vue.html';

@Component({
    render, staticRenderFns
})
export class MyComponent extends Vue {
}

A global TypeScript definition file for *.vue.html module is required for importing a template using ES Module syntax. That file will be created for you when using the vue new project template!

Release Cadence

Starting version 4.0.0, instapack follows Semantic Versioning.

Bi-weekly releases (usually on 14th and 28th date of each month) will be performed for updating package dependencies. Bug reports will be dealt promptly. These actions will increment the patch version.

New non-breaking features will increment the minor version. Breaking changes will increment the major version.

Occasionally, beta builds will be published (instapack@beta) for showcasing the bleeding edge version of the tool.

Alternatively, you may build directly from the source code repository:

git clone https://github.com/ryanelian/instapack.git
cd instapack
npm link        # symlink global to local package for development
npm run build   # alternatively, `npm install -g typescript` then `tsc`
ipack --version

FAQ

Can I use insert_framework_name_here ?

Yes, absolutely!

You can even use jQuery or plain vanilla JS; don't worry, we're not gonna judge. :smile:

Add the packages required for your project using yarn / npm then start hacking. We'll take care of the outputs.

Also, pull requests are welcomed if you have a great starting templates and books for those projects. We'd love to expand our collections!

What are the breaking changes when upgrading from instapack 4 to 5?

• Our supported Node.js runtime is now the latest version 8 LTS.

  • Node.js 8.3.0 and above ships with Ignition + Turbofan execution pipeline which boost overall compiler performance and shrink memory footprints!

  • Internally, we've moved from Browserify to the more modern webpack module bundler.

• We have a new recommended tsconfig.json. Type: ipack new tsconfig in your project root folder (where the package.json and tsconfig.json is located) to upgrade!

  • It uses a standardized ES2015 module code generation instead of CommonJS

  • It allows Synthetic Default Imports syntax for importing non-ES modules just like a default-exported ES modules!

• We've changed the CSS input file entry point from site.scss to index.scss. Please rename the said file!

• We've changed the default JS and CSS output file names to ipack.js (from bundle.js) and ipack.css (from site.css).

  • Make sure to update your <script src="..."> and <link href="..." /> references in the HTML files!

  • If that action is prohibitive, simply use the new jsOut and cssOut options to emit output file names identical to instapack 4:

{
  "instapack": {
    "jsOut": "bundle.js",
    "cssOut": "site.css",
  }
}

What are the breaking changes when upgrading from instapack 5 to 6?

Modules imported from node_modules will now be extracted automatically to [jsOut]_modules.js:

• For example: ipack_modules.js; this file must be included using <script> tag BEFORE the main app file ipack.js

• This change greatly improves development build speed, because instapack does not need to re-bundle library modules repeatedly!

HTML template compilation mode in package.json (string vs vue) has been removed in favor of special extension .vue.html to:

• Allow a project to have both stringified HTML and pre-compiled Vue.js HTML.

• Simplify instapack, to make it more beginner-friendly by reducing the number of obscure options and templates...

In light of the final version of AngularJS 1.7 LTS, it is recommended for newer projects to use Vue.js / React / Inferno instead.

• Therefore, angular-material template has been removed and angular-bootstrap template has been renamed to angularjs

• jQuery has been re-added into angularjs template to improve compatibility with legacy browsers, especially with Bootstrap 3.

Unfortunately, the enterprise world is not ready for JavaScript running natively in ES2015 and beyond...

The no-longer-maintained UglifyES has been dropped in exchange for the hopefully-more-stable UglifyJS 3. This change imposes stricter build requirements:

• Only es5 build target (set in tsconfig.json) is currently supported. Setting ES2015+ as build target WILL cause build error!

• Attempting to import a non-TypeScript ES2015+ module will fail the build! This downgrade guards the project against ninja browser incompatibilities.

I thought files should not be bundled because of HTTP/2?

Nope.

Also, in IIS, HTTP/2 is only supported when using Windows Server 2016. Many of our customers are still using Windows Server 2012 R2 to date.

Can I change the index.ts / index.scss entry point?

Nope.

Can I change the js / css folder name?

Nope.

My package restore / IDE is slow. Help!

Windows Defender or other anti-virus software appear to slow down package restore and IDEs when opening projects.

For this very reason, it is highly recommended to:

• Add anti-virus exclusion to Yarn installation folder: C:\Program Files (x86)\Yarn. To double check, type: where.exe yarn

• Add anti-virus exclusion to Yarn cache folder: C:\Users\Ryan\AppData\Local\Yarn. To double check, type: yarn cache dir

• Add anti-virus exclusion to NodeJS installation folder: C:\Program Files\nodejs. To double check, type: where.exe node

• Add anti-virus exclusion to Git installation folder: C:\Program Files\Git. To double check, type: where.exe git

• Use very short root folder name for projects, such as D:\VS, to avoid potential problems with Windows system paths over 260 characters long. Then exclude the folder from the anti-virus.
