我正在尝试在react+ts项目中使用pdfjs。
import React from "react";
import * as pdfjs from "pdfjs-dist"
export default function EditPdf() {
React.useEffect(()=>{
const doc = pdfjs.getDocument("helloworld.pdf");
doc.promise.then((pdf)=>{
console.log(pdf)
})
},[])
return (
<div>
content
</div>
)
}
我在这里导入它,但出现错误:
Error: No "GlobalWorkerOptions.workerSrc" specified.

在网上,这似乎足够“简单”......我可以做类似的事情:
import pdfjsWorker from "pdfjs-dist/build/pdf.worker.entry";
// ...
pdfjs.GlobalWorkerOptions.workerSrc = pdfjsWorker
但是
pdf.worker.entry
不存在。我在 node_modules 文件夹中搜索,找到了一个类似名称的 pdf.worker.mjs
文件。我尝试使用 import pfdjsWorker from "pdfjs-dist/build/pdf.worker.entry"
导入,但找不到此声明。最后我注意到存在一个 pdfjs.PDFWorker
类型声明,但我不确定如何使用它(没有文档)。
如何在 React+TS 项目中成功导入并使用 pdfjs + Worker?
您可以尝试通过
workerSrc
授予//mozilla.github.io/pdf.js/build/pdf.worker.mjs
。请参考此文档:https://mozilla.github.io/pdf.js/examples/
