1.angular-cli 之 angular.json 配置表引數說明

簡單建立一個demo專案

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是一個刪除了部分內容的angular.json僅用於講解使用，後面會給出完整json

引數	作用
$schema	關聯了JSON Schema在angular CLI 的執行config.json檔案
version	專案版本
newProjectRoot	這個屬性定義了CLI建立的新的內部應用和庫放置的位置，預設值為'projects'
projects	這個屬性，個人覺得有必要認真講一下。此屬性包含了本專案中所有的子專案的配置資訊。稍後單獨拿這個屬性詳細講解其注意點。
defaultProject	屬性表示該專案的名字

2.projects 下一級屬性名是子專案的名稱

子專案名稱的作用，可以用於ng 命令執行

比如上面的json有一個子專案名字 project-name-test

如果想單獨執行某個子專案時，可以執行

ng serve project-name-test

如果子專案不在projects內，執行 ng serve [project-name] 就會包一個錯

The serve command requires to be run in an Angular project, but a project definition could not be found.

建立一個子專案，可以執行

ng generate application project-name

而且，每建立一個子專案，都會有一個[project-name]-e2e的子專案在projects裡面

3.projects 子專案裡面的屬性說明

屬性	作用
root	指定了子專案檔案的根資料夾，可能是空值
sourceRoot	子專案原始檔目錄位置
projectType	子專案型別，`application` 或`library`
prefix	建立子專案時，用這個屬性來區分當前子專案是`component` 、`directive` 、`lib` ,或其他,當cli建立時會確定
schematics	`Schematics packages` 配置(本人暫時還不知道其具體作用)
architect	此屬性包含了專案的一些命令，比如`build` /`serve` /`test` /`lint` 或者自定義命令`extract-i18n`

以上部分屬性內容參考自Alfred的 angular.json引數詳解
