As many here I stumbled across converting .docx to .pdf. The only reasonable solution out there seems to be Gotenberg which is a Docker-powered stateless API and Gotenberg js client which allows to interact with Gotenberg much easier through JS interface.
To use JS client we need to define Gotenberg's Docker-powered address:
import { pipe, gotenberg, convert, html, please } from 'gotenberg-js-client'
const toPDF = pipe(
gotenberg('http://localhost:3000'), <--- here
convert,
html,
please
)
I'm no wizard of JS nor client-side nor backend so I want to ask you guys: how (if possible) I could implement it using Google Cloud solutions?
Now I'm using Firebase Cloud Functions to generate .docx (the same I do on the client-side) and I want to be able to convert them to .pdf (both client and backend). Is this achievable? Is this scalable?
You can use a Firebase Cloud Functions (which uses an underlying Cloud Function) with the nodejs runtime. But if you are not planning to run a Firebase App I would recommend you to use just a Cloud Function.
You can take a look at this quickstart to get an introduction. After that you can try to deploy your own function specifying yourgotenberg-js-client dependency in the package.json file.
The only thing you need to decide is how will the function access to the file. I recommend to store the pdf files in a Cloud Storage bucket and use the nodejs Cloud Storage client library to access them from within your Cloud Function.
