I need to dribble out JSON output a few times second, each looking like {stuff}. How should I do it:
[
{stuff},
{stuff},
...
]
or:
{stuff}
{stuff}
{stuff}
...
[
{stuff},
{stuff},
...
]
or:
{stuff}
{stuff}
{stuff}
...
In other words, a single item that if redirected to a file, would parse as JSON, even though it's meant to be read live. Or as a series of independent JSON objects?
Thanks the twitters! My answer is #2. I changed the option in the code to say "--ndjson-status" to communicate what's going on. Here are the two references people pointed me to:
jsonlines.org
ndjson.org
jsonlines.org
ndjson.org
The "correct" answer would be #1, but there's a whole lot of reasons streaming parsing of JSON is hard (#1), and that many tools are instrumented to deal with line-delimited JSON (#2).
