I know you can configure Express to output either pretty JSON (app.set("json spaces", 2)) or minified JSON (app.set("json spaces", 0)), but is there a way to override this global setting on a particular response?
For example, if I set json spaces to 0, I could pretty print doing something like:
app.get("/foo", function(req,res) {
res.json({"a":"b"}, 2);
});
Thanks!
Stringify wasn't working for me, for whatever reason. But setting json spaces did work.
app.set('json spaces', 2);
app.get("*", async (request, response) => {
...
response.json(m);
}

Thank you to loganfsmyth for the tip.
.type('application/json') if you're using .json().
A simple way to do it would be to use res.send and format the JSON on your own:
app.get("/foo", function(req,res) {
res.send(JSON.stringify({"a":"b"}, null, 2));
});
MDN has more documentation on JSON.stringify
Thanks for the great answer wjohnsto! Building off of your answer, and digging around in the response.js code, I had to make one modification to get it to work properly:
app.get("/foo", function(req, res) {
res
.set("Content-type", "application/json; charset=utf-8")
.send(JSON.stringify({"a":"b"}, null, 2));
});
I ended up creating a function sendPretty(res, data) for reusability.
