Can I convert a remote docx (on s3) to PDF?

[shaharsol]

Not sure what the syntax would be.

I try

    const signedUrl = await this.getSignedURL(bucket, docxKey);
    console.log('signed url: ', signedUrl);
    const toPDF = pipe(
      gotenberg('http://localhost:8008'),
      convert,
      url,
      office,
      set(filename('result.pdf')),
      please
    )

    const pdfStream = await toPDF(signedUrl);

and I always get 404 from Gotenberg as if it wasn't able to fetch the signed url tough it is accessible from curl or browser.

I think, Gotenberg doesn't support this, unfortunately :( You can ask for feature here, but for now, as I see, remote URL is considered HTML.

URL conversions work the same as HTML conversions.

For now, I guess, the only way is to download document and send it to Gotenberg as a file.

(You don't have to save document to the filesystem, if you don't want to — you can use Buffer or ReadableStream)

BTW to clarify, why you get 404:

Functions like convert, url, office, aside from setting conversion type, appends URL parts to the base Gotenberg URL, so in case of

const toPDF = pipe(
  gotenberg('http://localhost:8008'),
  convert,
  url,
  office,
  set(filename('result.pdf')),
  please
)

you get URL

http://localhost:8008/convert/url/office

and this is not a valid Gotenberg endpoint, of course.

Not sure, should I handle such cases in my client somehow, or not... I'll think on it

I've added few lines to README file, with example of streaming downloaded file to Gotenberg, without saving it to the disk.

// you can create this function as a static class field or module local variable,
// there is no need to create it anew for each conversion
const toPDF = pipe(
  gotenberg('http://localhost:8008'),
  convert,
  office,
  please
)

// --- 8< ---

const signedUrl = await this.getSignedURL(bucket, docxKey)

// I assume s3 uses HTTPS:
// import https from 'https'
https.get(signedUrl, async (document) => {
  const pdfStream = await toPDF({ 'document.docx': document })
  // ...
})

I'll leave this issue open for a while, though, because I want to think about handling issues, when you specify multiple conversion types (which is incorrect and should throw an exception).

Published new version 0.6.1

It will throw error

Cannot set "Office" conversion, already set to "Url"

For your op code
