5、import * as Img from "./path/to/image.png";
在导入时,我们还可以使用as关键字为导入的成员指定别名,这在避免命名冲突或简化代码时非常有用: // 使用别名导入变量import{ myVariableasvariableAlias }from'./myModule';console.log(variableAlias);// 输出:Hello, TypeScript!// 使用别名导入默认导出的类importDefaultClassasMyCustomClassfrom'./myModule';con...
import{locale}from"umi/locale"; 其实它的实现是创建了一个文件,通过webpack.alias将引用指了过去。这个做法非常棒,那么如何为它加上类型支持呢?只要这么配置tsconfig.json: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 {"compilerOptions":{"paths":{"umi/*":["umi","<somePath>"]}}} ...
import { fileURLToPath, URL } from 'node:url' export default defineConfig({ plugins: [ vue(), ], resolve: { alias: { '@': fileURLToPath(new URL('./src', import.meta.url)), }, }, }) 在tsconfig.json中配置: "baseUrl": "./", // 解析非相对模块的基础地址,默认是当前目录 ...
An interface can have multiple merged declarations, but a type alias for an object type literal cannot. interface可以继承(比如用extends),type不可以 interface可以实现有多个合并声明,type不可以 enum作为一种类型是什么意思? 在阅读pixi.js的源码中,发现有将enum作为了一种类型。 enum也可以作为一种类型去...
{ config.resolve.alias.set("image", path.resolve(__dirname, "public")); // 在文档中模拟库包的引入方式 // 例如发布了 algorithms-utils 库包之后, // import greet from 'algorithms-utils/greet.ts' 在 Vuepress 演示文档中等同于 // import greet from '~/src/greet.ts', // 其中 ~ 在这里...
export { Foo as Self } If we are talking about a library, this is something the maintainer needs to support and it's not that self-explanatory. Another option is to create a type alias in the importing file import * as Foo from './Foo.js'; type Foo = Foo.Foo; If our type req...
