创建一个ng2组件库开发工程

目标

创建一个基于angular2的组件开发工程，在此工程可以实现组件打包，组件演示；

目录结构图

步骤

1、利用angular2-cli脚手架创建一个默认工程；

2、修改package.json如下：

{
  "name": "glory-ui",
  "version": "0.0.7",
  "description": "component lib for Angular2",
  "main": "dist/index.js",
  "typings": "dist/index.d.ts",
  "files": [
    "dist",
    "resources"
  ],
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "e2e": "ng e2e",
    "watch": "tsc --watch",
    "lint": "tslint 'src/**/*.ts'",
    "pretest": "npm run lint",
    "test": "karma start",
    "prebuild": "rimraf dist",
    "build": "tsc",
    "ngc": "ngc -p .",
    "build-aot": "ngc -p tsconfig-aot.json",
    "build-release": "ngc -p tsconfig-release.json",
    "karma:debug": "karma start --auto-watch --no-single-run --browsers Chrome",
    "typedoc": "typedoc",
    "docs": "npm run typedoc -- --options typedoc.json --exclude '**/*.spec.ts' ./src/"
  },
  "devDependencies": {

    "karma-coverage-istanbul-reporter": "^0.2.0",
    "karma-jasmine": "~1.1.0",
    "karma-jasmine-html-reporter": "^0.2.2",
    "karma-mocha-reporter": "^2.0.4",
    "karma-phantomjs-launcher": "^1.0.1",
    "karma-sourcemap-loader": "^0.3.7",
    "karma-webpack": "^1.7.0",
    "protractor": "~5.1.0",

    "ts-node": "~2.0.0",
    "tslint": "~4.5.0",
    "tslint-loader": "^3.4.3",
    "typedoc": "^0.4.4",
    "typescript": "~2.2.0",
    "url-loader": "^0.5.7",
    "webpack": "2.3.1",

    "webpack-md5-hash": "^0.0.5",
    "webpack-merge": "^0.14.1",
    "webpack-stream": "^3.2.0"
  }
}

3、修改tsconfig.json如下：

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "dist",
    "baseUrl": "src",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2016",
      "dom"
    ]
  }
}

4、根目录新建tsconfig-aot.json如下：

{
  "compilerOptions": {
    "outDir": "dist",
    "target": "es5",
    "module": "es2015",
    "baseUrl": "src",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false,
    "suppressImplicitAnyIndexErrors": true,
    "lib": ["dom","es6"]
  },
  "include": [
    "src/app/components/**/*"
  ],
  "angularCompilerOptions": {
   "genDir": "aot",
   "skipMetadataEmit" : false
 }
}

5、根目录下创建gulpfile.js文件，内容如下：

'use strict';

var gulp = require('gulp'),
  concat = require('gulp-concat'),
  uglifycss = require('gulp-uglifycss'),
  rename = require('gulp-rename'),
  del = require('del'),
  flatten = require('gulp-flatten');

gulp.task('build-css', function () {
  gulp.src([
    'src/app/components/common/common.css',
    'src/app/components/**/*.css'
  ])
    .pipe(concat('glory-ui.css'))
    .pipe(gulp.dest('resources'));
});

gulp.task('build-css-prod', function () {
  gulp.src([
    'src/app/components/common/common.css',
    'src/app/components/**/*.css'
  ])
    .pipe(concat('glory-ui.css'))
    .pipe(gulp.dest('resources'))
    .pipe(uglifycss({"uglyComments": true}))
    .pipe(rename('glory-ui.min.css'))
    .pipe(gulp.dest('resources'));
});

gulp.task('images', function () {
  return gulp.src([
    'src/app/components/**/images/*.png',
    'src/app/components/**/images/*.gif',
    'src/app/components/**/images/*.svg',
    'src/assets/components/images/*.png',
    'src/assets/components/images/*.gif',
    'src/assets/components/images/*.svg'
  ])
    .pipe(flatten())
    .pipe(gulp.dest('resources/images'));
});

gulp.task('themes', function () {
  return gulp.src(['src/assets/components/themes/**/*'])
    .pipe(gulp.dest('resources/themes'));
});

//Cleaning previous gulp tasks from project
gulp.task('clean', function () {
  del(['resources']);
});

//Building project with run sequence
gulp.task('build-assets', ['clean', 'build-css-prod', 'images', 'themes']);

6、接下来再重点看下app下面的两个文件夹：

components存放组件相关代码，showcase存放组件演示代码；

7、命令行运行npm install安装全部依赖，到这里结构已经创建完成，可以尽情地写自己的组件了。写完组件可以选择上到到自己的npm帐户下面，提供项目调用
