angular2.0 笔记
1.angular-cli 之 angular.json 设置表参数申明
简朴建立一个demo项目
ng new project-demo{
"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
"version": 1,
"newProjectRoot": "projects",
"projects": {
"project-demo": {
"root": "",
"sourceRoot": "src",
"projectType": "application",
"prefix": "app",
"schematics": {},
"architect": {
"build": {},
"serve": {},
"extract-i18n": {},
"test": {},
"lint": {}
}
},
"project-name-test": {
"root": "",
"sourceRoot": "src",
"projectType": "application",
"prefix": "app",
"schematics": {},
"architect": {
"build": {},
"serve": {},
"extract-i18n": {},
"test": {},
"lint": {}
}
}
},
"defaultProject": "project-demo"
}上面的json是一个删除了部份内容的angular.json仅用于解说运用，背面会给出完全json
| 参数 | 作用 |
|---|---|
| $schema | 关联了JSON Schema在angular CLI 的实行config.json文件 |
| version | 项目版本 |
| newProjectRoot | 这个属性定义了CLI建立的新的内部运用和库安排的位置，默认值为’projects’ |
| projects | 这个属性，个人以为有必要仔细讲一下。此属性包含了本项目中一切的子项目标设置信息。稍后零丁拿这个属性细致解说其注重点。 |
| defaultProject | 属性示意该项目标名字 |
2.projects 下一级属性名 是子项目标称号
子项目称号的作用，能够用于ng 敕令实行
比方上面的json有一个子项目名字 project-name-test
假如想零丁运转某个子项目时，能够实行 ng serve project-name-test
假如子项目不在projects内，实行 ng serve [project-name] 就会包一个错
The serve command requires to be run in an Angular project, but a project definition could not be found.
建立一个子项目，能够实行ng generate application project-name
而且，每建立一个子项目，都邑有一个[project-name]-e2e的子项目在projects内里
3.projects 子项目 内里的 属性 申明
| 属性 | 作用 |
|---|---|
| root | 指定了子项目文件的根文件夹，多是空值 |
| sourceRoot | 子项目源文件目次位置 |
| projectType | 子项目范例， application 或 library |
| prefix | 建立子项目时，用这个属性来辨别当前子项目是 component、directive、lib,或其他,当cli建立时会肯定 |
| schematics | Schematics packages 设置(本人临时还不晓得其详细作用) |
| architect | 此属性包含了项目标一些敕令，比方 build/serve/test/lint 或许自定义敕令 extract-i18n |
以上部份属性内容参考自
Alfred的 angular.json参数详解
