[英]Parcel does not generate type declarations for a TypeScript library
I just started using Parcel and I have this issue, where it is not generating type declarations and emits an empty index.d.ts
file instead.我刚开始使用 Parcel,我遇到了这个问题,它没有生成类型声明,而是发出一个空的
index.d.ts
文件。 Here is my configuration in package.json
:这是我在
package.json
中的配置:
{
// ...
"scripts": {
"prepare": "yarn build",
"check": "tsc --noEmit",
"watch": "parcel watch --no-source-maps --no-cache",
"build": "parcel build --no-source-maps --no-cache"
},
"main": "./lib/index.js",
"source": "./src/index.ts",
"types": "./lib/index.d.ts",
"module": "./lib/esm/index.js",
"devDependencies": {
"@parcel/packager-ts": "^2.0.1",
"@parcel/transformer-typescript-types": "^2.0.1",
"@types/node": "^16.11.9",
"parcel": "^2.0.1",
"typescript": "^4.5.2"
},
// ...
}
And here is a simple example of an type
that I have defined in my code:这是我在代码中定义的
type
的简单示例:
export type Response = {
/**
* The list of added/removed hashes
*/
hashes: string[];
/**
* The list of skipped hashes
*/
skipped: string[];
};
Any ideas why this is happening?任何想法为什么会发生这种情况? Have I configured something incorrectly?
我是否配置错误? I have followed this documentation.
我已遵循此文档。
Thank you.谢谢你。
It looks like your issue is caused by the the "incremental": true
line in your tsconfig.json
's "compilerOptions"
(see here ).看起来您的问题是由
tsconfig.json
的"compilerOptions"
中的"incremental": true
行引起的(请参见此处)。 If you remove this line, parcel should generate .d.ts
files as expected.如果删除此行,parcel 应按预期生成
.d.ts
文件。
(In an ideal world, parcel should be able to handle this case - I filed this bug with parcel to report the problem - it should be an easy fix). (在理想情况下,parcel 应该能够处理这种情况 - 我用 parcel 提交了这个错误以报告问题 - 这应该是一个简单的修复)。
