1.angular-cli 之 angular.json 配置表参数说明
简单创建一个 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 是一个删除了部分内容的 angular.json 仅用于讲解使用，后面会给出完整 json
参数
作用
$schema
关联了 JSON Schema 在 angular CLI 的执行 config.json 文件
version
项目版本
newProjectRoot
这个属性定义了 CLI 创建的新的内部应用和库放置的位置，默认值为 ’projects’
projects
这个属性，个人觉得有必要认真讲一下。此属性包含了本项目中所有的子项目的配置信息。稍后单独拿这个属性详细讲解其注意点。
defaultProject
属性表示该项目的名字
2.projects 下一级属性名 是子项目的名称
子项目名称的作用，可以用于 ng 命令执行 比如上面的 json 有一个子项目名字 project-name-test
如果想单独运行某个子项目时，可以执行 ng serve project-name-test
如果子项目不在 projects 内，执行 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.
创建一个子项目，可以执行 ng generate application project-name
而且，每创建一个子项目，都会有一个 [project-name]-e2e 的子项目在 projects 里面
3.projects 子项目 里面的 属性 说明
属性
作用
root
指定了子项目文件的根文件夹，可能是空值
sourceRoot
子项目源文件目录位置
projectType
子项目类型，application 或 library
prefix
创建子项目时，用这个属性来区分当前子项目是 component、directive、lib, 或其他, 当 cli 创建时会确定
schematics
Schematics packages 配置 (本人暂时还不知道其具体作用)
architect
此属性包含了项目的一些命令，比如 build/serve/test/lint 或者自定义命令 extract-i18n
以上部分属性内容参考自 Alfred 的 angular.json 参数详解
