我为Typescript的Voca.js写了一个非常简单的插件。您可以找到源代码here。
index.ts
import VueVoca from './vue-voca';
export {
VueVoca
};
vue-voca.ts
import vue from 'vue';
export default {
install(Vue: typeof vue) {
Vue.prototype.$voca = require('voca');
}
};
vue.d.ts
import Vue from 'vue';
import vc from 'voca';
declare module 'vue/types/vue' {
export interface Vue {
$voca: vc.VocaStatic;
}
}
要创建npm软件包,请使用以下命令
vue-cli-service build --name vue-voca --entry ./src/index.ts --target lib
和npm pack
。
package.json
{
"name": "vue-voca",
"version": "1.0.0",
"private": false,
"scripts": {
"serve": "vue-cli-service serve ./example/main.ts --open",
"build": "vue-cli-service build --name vue-voca --entry ./src/index.ts --target lib",
"prepublishOnly": "npm run build"
},
"dependencies": {
"@types/voca": "^1.4.0",
"voca": "^1.4.0",
"vue": "^2.6.7"
},
"devDependencies": {
"@vue/cli-plugin-typescript": "^3.4.1",
"@vue/cli-service": "^3.4.1",
"fibers": "^3.1.1",
"sass": "^1.17.2",
"sass-loader": "^7.1.0",
"typescript": "^3.3.3333",
"vue-cli-plugin-component": "^1.10.5",
"vue-template-compiler": "^2.6.7"
},
"files": [
"dist/*.css",
"dist/*.map",
"dist/*.js",
"src/*"
],
"keywords": [
"vue",
"component"
],
"types": "src/vue.d.ts",
"typings": "src/vue.d.ts",
"main": "dist/vue-services.umd.js",
"module": "dist/vue-services.common.js"
}
tsconfig
{
"compilerOptions": {
"target": "es5",
"module": "esnext",
"strict": true,
"jsx": "preserve",
"declaration": true,
"importHelpers": true,
"moduleResolution": "node",
"esModuleInterop": true,
"allowSyntheticDefaultImports": true,
"sourceMap": true,
"baseUrl": ".",
"types": [
"webpack-env"
],
"paths": {
"@/*": [
"src/*"
]
},
"lib": [
"esnext",
"dom",
"dom.iterable",
"scripthost"
]
},
"include": [
"src/**/*.ts",
"src/**/*.tsx",
"src/**/*.vue",
"tests/**/*.ts",
"tests/**/*.tsx"
],
"exclude": [
"node_modules"
]
}
但是在另一个项目中使用npm软件包后,出现了错误。 VueVoca无法识别,并且Typescript无法很好地使用它。
webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:620 [Vue warn]: Error in render: "TypeError: Cannot read property 'swapCase' of undefined"
found in
---> <HelloWorld> at src/components/HelloWorld.vue
<App> at src/App.vue
<Root>
有人可以帮助我用正确的npm
软件包编写正确的插件吗?
答案 0 :(得分:0)
这里的问题是您已经用TypeScript编写了插件。因此,至少有两个类型定义:
index.ts
文件的类型定义现在您的package.json
的{{1}}字段指向types/typings
。对于TypeScript,导入此库时,它将推断模块扩充代码。无法在vue.d.ts
文件中找到它。因此,在您的Vue组件中,index.d.ts
将与TS一起使用,但this.$voca()
作为解决方案,请将import { VueCoca } from 'vue-coca';
字段设置为types
文件。另外,为了简洁起见,将<PATH>/index.d.ts
重命名为vue.d.ts
。然后,该库的调用者应编写自己的 typings文件-* .d.ts 文件,他将在其中导入该文件,例如:
augment.d.ts
或者,您也可以将此扩展文件导入插件的主import 'vue-coca/<PATH>/augment.d';
文件中。通过这种方法,该库的用户将不必单独包含它。
