How can I output the json with newlines?

[pmcl77]

Im simply setting up the jsonformatter with:

streamformat = jsonlogger.JsonFormatter("%(asctime)s %(levelname)s %(levelno)s %(module)s %(message)s %(lineno)s ")

It will output the json all in one line. Is there an option to have a "pretty" output somehow like you showed in your example output?

If you want it in a pretty output from stdout, you could run your server and pipe it into jq. In my case I ran something like uvicorn main:app --reload | jq

If you have a mix of json and non-json lines I found the following works:

uvicorn main:app --reload | jq -R -r '. as $line | try fromjson catch $line'

Unfortunately the jq trick didnt seem to work for me, when debugging in cli, stack traces put invalid json on stdout. However setting indent on the constructor seems to work fine:

formatter = jsonlogger.JsonFormatter(json_indent=2)
