Detailed explanation of using Angular CLI to generate code from blueprints
This article mainly introduces the detailed explanation of using Angular CLI to generate code from a blueprint. Now I share it with you and give it as a reference.
The first article is: "Using angular cli to generate angular5 projects": http://www.jb51.net/article/136621.htm
This article mainly talks about generating Components , Directive, Service, class, interface, enum, etc.
ng generate
The format of this command is ng generate < Blueprint name>
You can also use the --dry-run parameter to list the files to be generated instead of actually generating them.
For example:
ng generate component person, a person.component.ts will be generated.
ng generate service sales-data will generate a sales-data.service.ts.
ng generate class user-model will generate a user-model.ts which contains the UserModel class.
#Components.
ng The command to generate xxx xxx is still a bit long, here angular cli has built-in aliases for commands, for example:
ng generate component person In this command, the generate in
can be replaced by the letter g, and the component in
can be replaced by the letter c Replace.
So these two commands are equal:
ng generate component person ng g c person
You can go here to view component-related commands and aliases:
https://github.com/angular/angular-cli/wiki/generate-component
Possibly commonly used command parameters are:
- ##--flat Indicates whether there is no need to create a folder
- --inline-template (-it) Whether the template should be placed in the ts file
- -- inline-style (-is) Whether the style should be placed in the ts file.
- --spec Whether it is necessary to create a spec file (test file)
- --view-encapsulation (-ve) View Encapsulation strategy (simply understood as the scope strategy of style files).
- --change-detection (-cd) Change detection strategy .
- --prefix Set the prefix of this component
- --dry-run (-d), print out the generated file list , instead of directly generating.
ng generate component person ng generate component person --inline-template --inline-style ng g c person ng g c person -it -is
ng g c person -d
ng g c student -ve Emulated -cd OnPush
ng g d filter-box -d
ng g d filter-box
Look at the directory structure:
ng g d filter-box2 --flat false
##Now you have your own folder.
Commit it.
Service.ng g s order-data -d
可以看到 这个命令会生成flat结构的service.
然后把-d去掉, 真实生成文件:
ng g s order-data
可以从源码管理看到, 只生成了两个文件, 并没有在app.module里面注册:
当然可以在这里写代码把刚才生成的service注册进去.
但是正确的做法是使用 -m 参数来指定需要注册的module:
ng g s order-data2 -m app
这次生成的order-data2 service就会在app.module.ts里面进行注册了.
然后再commit一下.
Model/Interface/Enum/Pipe.
model:
ng g cl models/user
这个命令会创建models文件夹, 然后在里面创建user这个model:
interface:
ng g i models/animal
enum:
ng g e models/gender
commit一下.
Pipe.
ng g p camel-case
除了生成两个文件之外, 这个命令默认也会更新app.module.
Module.
ng g m login
可以看到module默认是自带文件夹的.
然后我试试添加一个component, 目的是要在login module进行声明:
可以看到我要创建的welcome component默认是在app.module里面进行声明的, 这时候如果想要在login module进行声明, 就要使用 -m 参数:
去掉-d执行生成命令后:
上面是我整理给大家的,希望今后会对大家有帮助。
