I have a 15-20 page text heavy template file, with few data points to load from json file (may be 10-15 data points). When I am doing load testing the generation of pdf is taking around 800ms. Is there some performance tips I can apply to speed up the generation?

Are you doing clean or incremental compilations, i.e. typst compile or typst watch?

typst compile as each time json files will be different

hmm, yeah. then I think there is not much you can do from your side unfortunately.

#

Typst could in theory be a bit faster if it was all one process invocation (less font loading etc.), but there is no way to do that atm.

#

except of course for doing everything in one doc, but that yields problems with heading counters etc.

If I remember correctly, typst watches for jsons, that #read("file.json"), so you can run typst watch, and do something like

cat 1.json > common.json
# wait a bit
mv main.pdf 1.pdf

yeah, maybe you can build something with that.

Ok

#

instead of just sleeping on compilation, you can watch for .pdf change

#

Should there be a background process which needs to constannlty running for typst watch?

#

yes, if you terminate typst, how it will compile? 🙂

#

if you have different json files, how are you read them? manually replacing path for each new compilation? something like sed? using latest typst and sys.inputs?
