QUESTION
I found this code which, you select a pdf file in an input, and it returns the number of pages it has. It turns out that with this way of reading pdfs is the only one I have found that reads absolutely all pdfs correctly.
What I am trying to do is to isolate the code that reads the pdf file, so that I can pass it the path to the file instead of using the input. It is to then read all the files in a folder and display the total number of pages.
But I can't figure out where exactly I would have to pass the path to the pdf file.
...ANSWER
Answered 2022-Apr-14 at 20:32You can't.
Browsers don't let you access local paths on a user's computer for security reasons.
The browser doesn't get to know that the pdf is at /home/USERNAME/confidentialdocs/file.pdf, it just gets a data blob with a given filename.
QUESTION
it.only('test', async() => {
const lol = pdfjs.getDocument({data: data, password: "123"})
lol.promise.then((ex) => { return ex }).catch((err) => {
console.log(err)
throw err;
});
});
ANSWER
Answered 2022-Apr-03 at 09:49Just add await before the promise expression. You don't even need those then and catch.

QUESTION
Google Chrome allows you to preview local PDF files in the browser like pictured below:
I am working on an extension that takes whatever PDF is in the browser preview and opens it in my custom editor/markup tool.
I have been successful in loading PDFs from remote URLs because I can just send the remote URL to my server, download it there, and open the PDF in my app using PDFjs.
How can I accomplish the same functionality for local PDF files?
I have looked into possibly using javascript to create a File object from local PDF files but Chrome doesn't allow access to the local file system.
I am hoping to accomplish this functionality by the user just clicking my extension icon, similar to the popular extension, Kami.

QUESTION
I have been using ng2-pdfjs-viewer in Angular components. However, I need the div element to occupy space in DOM only if a condition is met. So I used *ngIf for the div. However, when I use ngIf the page breaks. In console it does not show any error in main window. In console sidebar there is a notification of 4 errors in vendor.js. However, the errors can not be seen.
component.html: the part which uses ng2-pdfjs-viewer
...ANSWER
Answered 2022-Jan-24 at 13:44Not knowing the contents of pdfViewerAutoLoadCE.pdfSrc || pdfViewerAutoLoadJD.pdfSrc nor seeing the effects of "page broken" it is hard to know for sure whats the problem. But what if you wrap your pdf viewer in ng-container with someCondition upon which the pdf would be shown or not?
If necessary please adjust the ng-container to depth where only pdf-viewer is affected so that your top level div's stay in the template. That should help to keep your page intact.
