vscode自定义片段

1、Code -> 首选项 -> 用户片段

 

 

 

2、填入代码片段文件的名称，然后回车

 

 

3、在打开发文件中，写入代码片段的配置，如：

{
    // Place your 全局 snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and 
    // description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope 
    // is left empty or omitted, the snippet gets applied to all languages. The prefix is what is 
    // used to trigger the snippet and the body will be expanded and inserted. Possible variables are: 
    // $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. 
    // Placeholders with the same ids are connected.
    // Example:
    "react_s_page": {
        "scope": "javascript,typescript,javascriptreact,typescriptreact",
        "prefix": "react_s_page",
        "body": [
            "/* 三方库 */",
            "import React from 'react'",
            "import { Link } from 'react-router-dom'",
            "",
            "/* redux 链接组件 */",
            "import concatRedux from '@utils/concatRedux'",
            "",
            "/* 引入 ts 公共 interface定义 */",
            "import {IConnectProps} from '@tsDefine/ICommon'",
            "",
            "/* 引入公共组件 */",
            "import Page from '@components/Page'",
            "",
            "/* 相对路径引入组件 */",
            "",
            "/* 引入样式 */",
            "import './index.scss'",
            "",
            "/* ts定义interface */",
            "interface IProps extends IConnectProps { }",
            "interface IState {}",
            "",
            "/* concatRedux 定下定义变量，避免js 的 @装饰器被 ts 检测然后报错 */",
            "const conncatRedux: Function = concatRedux;",
            "",
            "@conncatRedux('/$1', ['$2'], ['$3'])",
            "export default class Center extends React.Component<IProps, IState> {",
            "    componentDidMond(){",
            "",
            "    }",
            "    render() {",
            "        return (",
            "            <Page title='$4' className='page_$5'>",
            "",
            "            </Page>",
            "        )",
            "    }",
            "}",
        ],
        "description": "react 页面框架"
    }
}

 

4、然后就可以再定义的类型的文件中使用该代码片段，如我在 scope 中定义了 javascript,typescript,javascriptreact,typescriptreact 这四种类型的文件中可以使用 react_s_page 前缀插入该代码片段。
