浏览简体中文文档

• Create Modular Front-End Build System, organize the source by module, using relative path, html/js/css/img/fonts/tpl are in one same folder, like Baidu FIS. Good concept for FE source management / development.
• Concept Introduction: 前端工程之模块化
• Component Oriented Solution, based on gulp. More simple, flexible, expandable and stable. Everyone know gulp can do secondary development.
• Support base64 image in html/CSS
• Support JS/CSS inlnied in html
• Support require('main.css'), require css file in js
• Intergrated with spritesmith, support auto sprite img
• Intergrated with icon-font, support SVG 2 Iconfont.
• Intergrated with usemin，support complex combo/package.
• Supoort FE Tpl embed function， the .tpl file will packaged into js file，support async js loading.
• Intergrated with SCSS|ES6|ReactJS|Vuejs|Babel|Browserify|cssnano|uglify|imagmein and other plugins，One-Stop Solution Service， very Simple and Strong
• High scalability, compatiable with almost gulp plugins, you can use them in gulpman. For example, you can put browser-sync in your gulpman build system
• Intergrated with karma framework，support babel/es6 unit test and coverage result.

##Introduction

• Support Mac、Linux
• No full test under Windows. You can install gulp、gulp-sass manually
• Required Node >= 4.0.0
• *For npm >= 3, after run npm install, please manually install gulp-sass, babel-preset-es2015, babel-preset-react, browserify-css

##Install

• npm install gulpman --save-dev

Note

• If error happened in npm install，such as /usr/local/lib/node_modules permission error, fix this by sudo chown -R "$(whoami)"+Path
• sudo npm install is not recommended
• The imagemin-pngquant module needlibpng-devel，if in Linux, please run yum install libpng-devel at first
• If install failed, check the npm-debug.log to see if there are some ENOMEMerrors

##Config

###0. Support Auto Mode, no Config

• You can skip Config, and directly jump to Usage

###1. Config gulpfile.js:

• require the gulpman in your gulpfile.js，then it will load gm:publish, gm:develop into gulp tasks.
• gulp gm:publish or gulp gm:develop in terminal then it will work

/**
 * Gulpfile.js
 */


var gulp = require('gulp'),
    gman = require('gulpman')

// your other tasks ...
// xxx ...


/**
 * config gulpman ======================
 * Use config API
 * assets path, CDN, URL prefix
 */

gman.config({
    
    // whether use absolute path, default `true` 
    'is_absolute': true,

    // cdn prefix support［string|array|function］arguments
    'cdn_prefix': '', 

    // url prefix, defautl `/static`. This involves the server config ,such as the static path of nginx
    'url_prefix': '/static' 


    /** use spritesmith for css-img sprite
     * Based on Spritesmith: https://github.com/Ensighten/spritesmith
     * Automatecially generate Sprite Image & CSS
     **/
    //'spritesmith': { },
    
    /** usemin config **/
    // 'usemin': {}


    // The COMPONENTS directory
    'components': 'components',

    // For development assets and templates folder, related to Server Config
    'runtime_views': 'views',
    'dist_views': 'views_dist',

    // For production assets and templates folder, related to Server Config
    'runtime_assets': 'assets',
    'dist_assets': 'assets_dist',

    // The js library dir, set as a global module. Also you can set as `bower_components`
    'lib': 'lib', 

    // You can add one customer global directory, so you can require module name directly, like: `require ('xxx')`. The xxx is in this directory
    'global': 'common' 
})

###2. How to config CDN better

• cdn_prefix support String, Array, Function
• if argument is array, the CDN will be an random value
• if argument is function，it would input one argument, mediaFile

'cdn_prefix': function (fileName) {
        
        console.log(fileName)

        var c_list = [
            'http://s0.com', 
            'http://s1.com', 
            'http://s2.com', 
            'http://s3.com',
            'http://s4.com'
        ]
        // You can customized your strategy
        if(hostFile.match(/\.html$/gm)){
            return c_list[0]
        }else {
            return c_list[1]
        }
    },

###3. About is_absolute

• is_absolute is the dist path of source in html. default true. the dist path is like /static/home/main.js

• [*]Need consistent config with Server, like nginx, apache

• If no local server, you can set is_absolute as false, use relative path. Like ../../assets/static/home/main.js

###4. gulpman directory

• Use gulpman to arrange your directory as component，The root component dir can be./components(default). If you have one component named foo, then ./components/foo，all related assets such as html|js|css|fonts|image should be put in foo folder.

• This solution for assets can be high efficiency and easy to maintain.

• gm:develop to start develop mode, the views dir and assets dir can be generated automatically

• gm:publish to publish assets in production env. The views_dist and assets_dist can generated.

###5. What is global directory

• For Browserify packing, the js module in global dir can be directly require or import in es6/js code

• In gulpman.config, the lib和global are global directory. Take an example:

• In components/lib directory, you have one module foo.js，then it is components/lib/foo.js. So when you use foo in your es6 file, you can use it like: import foo from 'foo', no need write as import foo from '../lib/foo'

• similarly, global option can set your dir as global module dir. You can set bower dir as your lib dir.

• Please make no conficts in your global dir

###6. Support for complex and multi level directory in config

• Such as:

gulpman.config({
    'is_absolute': false,
    'components': 'components/cc',
    'runtime_views': 'runtime_views/rv',
    'dist_views': 'dist_views/dv/dv',

    'dist_assets': 'dist_assets/da',
    'runtime_assets': 'runtime_assets/ra/ra',
})

##Usage

###1. CLI run Task:

# Create components directory and add one demo
# init components dir and a html demo
gulp gm:init


# develop and watch mode，watchings files changes and update files
gulp gm:develop

# Watch one special component
gulp gm:develop -c component_name


# publish assets in production env
gulp gm:publish

# publish command support `-a`和`-v` parameters to set output assets/views path.
gulp gm:publish -v your_views_dist -a your_assets_dist

# clean dist files
gulp gm:clean

# clean dist files, including subfolders
gulp gm:clean-deep

# Generate one developing assets/views files, but not in watching mode
# compile for develop, not watch
gulp gm:compile

###2. Watch one special component in development

• When the project become huge, if we watch all components assets, it will be low efficiency，so we can use gulpman to watch special component to get better performance

• Fox example, if we want watch the home component:

gulp gm:develop -c home

###3. Use React in gulpman

• Install React: npm install react react-dom
• Use React in ES6:

import React from 'react';
import ReactDOM from 'react-dom';

// xxx

###4. Use tpl file in js|es6|jsx

• Support .tpl file, it will be packaged in dist js files.

• Usage: import dialogTpl from './dialog.tpl' or var dialogTpl = require('./dialog.tpl')

###5. Usge base64 img in HTML/CSS

• Just add ?_gm_inline in assets src path in html/css
• The base64 code will be inlined in html/css

#####html

<p class="play"> 
    <img width="480" alt="Karat 克拉" src="./img/testb64.png?_gm_inline" />
</p>

#####CSS/SCSS

.test {
    background: url(./img/testb64.png?_gm_inline) no-repeat;
}

###6. Use inlined CSS/JS in html by querystring

• Like base64, just add ?_gm_inline in url path

<script src="./plugin.js?_gm_inline" type="text/javascript"></script>

<link href="./dialog.css?_gm_inline" rel="stylesheet" type="text/css" >

• The inlined sources will be auto updated when source files changed.

###7. Use Sprite img in css

• Based on spritesmith, you can transport usemin opts in gulpman.config.
• More detail about Spritesmith: https://github.com/Ensighten/spritesmith
• Usage: In scss file, just add ?_gm_sprite to img url

.demo {
    background: url(./img/abc.png?_gm_sprite) no-repeat;
    
    /* other style you can set ...*/
    width: 50px;
    height: 50px;
}

###8. Use Usemin

• You can tranport usemin opts in gulpman.config
• More detail about usemin: https://github.com/zont/gulp-usemin
• Uage: just add usemin build comments in html. Support js|css|inlinejs|inlinecss syntax
• Note: Just write relative path in usemin build comment. Then gulpman can calculate absolute path for assets.
• If you don't write output path, the gulpman will combo one new ouput file name automatically.

<!-- build:css ./home.css -->
<link rel="stylesheet" type="text/css" href="./main.css">
<link rel="stylesheet" type="text/css" href="./fff.css">
<!-- endbuild -->


<!-- build:js ../lib/base_lib.js -->
<script type="text/javascript" src="../lib/jquery.js"></script>
<script type="text/javascript" src="../lib/react.js"></script>
<!-- endbuild -->

###9. Use js tpl template

• Put the .tpl files in your component, and use require or import in ES6, then the tpl files will be packaged in js files.
• All tpl will be convertd to text string into js files.
• Base64 img and CSS/JS Embed are supported in Tpl

• import tpl in es6

    import dialogTpl from './dialog.tpl'

• require

    var dialogTpl = require('./dialog.tpl')

###10. Use iconfont convert svg to fontface

• Convert SVG to icon-font, use @font-face in css
• Run gulp gm:iconfont:install before first running
• Put the svg files in components/iconfonts/source directory, then run gulp gm:iconfont to begin start convert
• The icon-font and css will generated in iconfonts/gmicon folder

###11. Support LAB.js to load async js

• Add LAB.js in your project
• Use LAB API to load js, use relative path
• Example: $LAB.script("../testload/test.js").wait(()=>{console.log('test loaded')})

###12. Require CSS in JS

• Require css files in your es6/js files
• The CSS contents will be packaged into js files, and automatically injected to html when page opend. Using style tag
• Should keep the .css extname
• Example: require('./style.css') or import style from './style.css'

###13. Use karma for Unit Test

• Run gulp gm:karma:install before first running, it will install dependencies and generate karma.conf.js.
• In your one component folder, create one folder named spec, then put your spec es6 files in the spec folder, the file extname must be .es6
• Run gulp gm:karma:start in CLI to start Karma Unit Test, you can view the coverage result in coverage foloder
• Set one special spec folder、browsers and other karma options, you can set them in karma.conf.js
