eth new

create files by the [name] and a specified type.

New Options

category	string	new file category
test	boolean	whether append test for controller / service / model

Available category

• default: will create controller, service and model.
• controller: will create a controller.
• service: will create a service.
• model: will create a model, the model depends on mongoose.

create controller / service / model

  eth new user --category default

or

  eth new user -c default

Actually the [name] parameter is a path relative to app/controller / app/service / app/model

In this example, it will create app/controller/user.ts, app/model/user.ts, app/service/user.ts.

create a sub directory controller / service / model

  eth new permission/role --category default

or

  eth new permission/role -c default

It will create app/controller/permission/role.ts, app/model/permission/role.ts, app/service/permission/role.ts.

eth delete

delete files associated with the [name]

  eth delete user

It will delete app/controller/user.ts, app/model/user.ts, app/service/user.ts.

eth rename

Rename Options

name	type	description
newPath	string	new path

rename files associated with the [name]

  eth rename user -n masterUser

or

  eth rename user -newPath masterUser

It will rename app/controller/user.ts, app/model/user.ts, app/service/user.ts to app/controller/masterUser.ts, app/model/masterUser.ts, app/service/masterUser.ts

It will also change the file content!!!

Once user renamed to masterUser, the app/controller/masterUser.ts content is changed.

import { Controller } from 'egg'

/**
 * MasterUser Controller
 *
 * @export
 * @class MasterUserController
 * @extends {Controller}
 */
export default class MasterUserController extends Controller {
}

Customizations

You can setup your own templates.

eth.config.json

create an eth.config.json file under the project root.

name	type	default	description
ext	string	".ts"	file extenision, you can specify ext to ".js" if you use JavaScript to develop egg project
templateDir	string	""	custom template path, relative to the project root
execEts	boolean	true	execute egg-ts-helper after command executed. It will take effect when ext is ".ts"
renameContent	boolean	true	rewrite file content when executing rename command
customData	object	{}	pass custom data to custom template when executing new command

Example

Let's customize a template and inject an author name by setting customData.

eth.config.json

{
  "ext": ".ts",
  "templateDir": "template",
  "execEts": true,
  "renameContent": false,
  "customData": {
    "Author": "Dada"
  }
}

template/comtroller.tpl

import { Controller } from 'egg'

/**
 * <%=pascalCaseName%> Controller
 * 
 * @author <%=Author%>
 * @export
 * @class <%=pascalCaseName%>Controller
 * @extends {Controller}
 */
export default class <%=pascalCaseName%>Controller extends Controller {
}

There are four built in variables: name, pascalCaseName, testName, modelTestRootRelative

execute new command

  eth new user -c default

The content in app/controller/user.ts will like this:

import { Controller } from 'egg'

/**
 * User Controller
 *
 * @author Dada
 * @export
 * @class UserController
 * @extends {Controller}
 */
export default class UserController extends Controller {
}
