I have already read How to incorporate TeX into a website? There is a sketch of the way of compiling to PDF from the web page, with limitations.
Are there any easy to use methods of achieving this goal? A few years later there should be some standard tool, however I haven't found it yet...
standard tools, so it is not at all clear what exactly you hope to find. It isn't even clear which answer you are looking at since there are many. If you don't want what is asked for there, what do you want? What is supposed to happen to the PDF? What is it meant to be compiled from? What at all are you trying to do? – cfr Jan 08 '17 at 02:25shouldin what sense? Are you volunteering to provide them? – cfr Jan 08 '17 at 02:48standard methodfor this, because so much will depend on the details of what you are doing, who will have access etc. It is always a trade-off: security vs. user features. Etc. etc. – cfr Jan 08 '17 at 02:56pdflatexon your server and display its output on a webpage (which I gather from your mention of @xport's answer from the other question), there is nothing here specific to TeX/LaTeX: you'd do exactly the kind of things you'd do for running an arbitrary program on your server and displaying its output on the webpage, with similar security considerations and all that. (If you want pdflatex to run inside the browser of the user viewing your webpage, that is another matter: probably texlive.js is state-of-the-art, and it's slow.) – ShreevatsaR Jan 08 '17 at 08:57
