how to read a pdf file using nodejs ?
I have two issues:
1)I have a pdf file and i just want to read it and and display the contents in the browser.
2)Read and display the content of a specific page of file
If you want node to display a PDF file to a browser, you can simply have node send the PDF file upon HTTP request: res.sendFile('./example/file.pdf');
This previously answered question has more options and further details for sending PDF to the browser.
If you are trying to read (parse) the contents of the PDF, you can use pdf2json to figure out what part of the PDF file you want to display.

After making and downloading pdf files using package pdfMaker. I need to get the pdf file just downloadedInorder to send as email attachment.
Is there any mechanism to do so?
I used the antDesign file upload component in one form. After the file is fully uploaded, I save the file information in the model I want to send to the server (the output of the file upload component is attached). Now my question is how should I save the file on the server with this information? Files are sent in different formats (png, jpg, pdf, ...) and I am looking for a solution to store these files on the server.
You should use originFileObj, get it and then append it to FormData, and afterward send it by using axios or fetch. There is an example in the antd documentation about it
We have some code which downloads a PDF file from Google Drive using the Drive API, after that we use the file to build a new envelope and send it to the customer.
Using the same file, some of these requests work, and some come back with an error "PDF_VALIDATION_FAILED".
I have the log(file) file which contains the base64 of the file and the request information, using an external tool to convert the base64 to PDF it seems to be valid and also I tried to open the file using Adobe acrobat and the document appears fine.
Is there any documentation on what makes a pdf invalid?
Thanks in Advance
If you can upload the file to a DocuSign envelope using the DocuSign web app, but it doesn't work when you use the API:
If the file type is not pdf then include the file extension in the name attribute. Eg contract.docx. The fileExtension attribute is somethimes not used by the platform.
You have a problem with your Base64 encoding method. Modify one of the DocuSign code examples to send your file and it will work.
I would like to know if there is an JavaScript API for Excel to tell the size of an Excel file.
Could anyone help?
No. The browser (including JavaScript) don't access files on the clients computer i.e. Excel file. Upload the file to the back-end, and allow the server to analyse the file, and send result back to client/browser (JavaScript)

what i have to do change if i want to download a file (.csv or .xlsx) from an url ?
You have to change nothing. The code behind the link works for all sorts of files. I just named the method "getImage...()" because the topic of original question was about downloading images.
