How to save the output of a console log object to a file

Question

I tried using JSON stringify object   but it doesn t go down on the whole structure and hierarchy   On the other hand console log object  does that but I cannot save it    In the console log output I can expand one by one all the children and select and copy paste but the structure is to big for that

There is another open-source tool that allows you to save all console.log output in a file on your server - JS LogFlush (plug!).

JS LogFlush is an integrated JavaScript logging solution which include:

cross-browser UI-less replacement of console.log - on client side.

log storage system - on server side.

This is really late to the party  but maybe it will help someone  My solution seems similar to what the OP described as problematic  but maybe it s a feature that Chrome offers now  but not then  I tried right-clicking and saving the  log file after the object was written to the console  but all that gave me was a text file with this      console js 230 Done   Array 50000  0     9999  10000     19999  20000       29999  30000     39999  40000     49999 length  50000  proto    Array 0    which was of no use to anyone   What I ended up doing was finding the console log data  in the code  dropped a breakpoint on it and then typed JSON Stringify data  in the console which displayed the entire object as a JSON string and the Chrome console actually gives you a button to copy it  Then paste into a text editor and there s your JSON

You can use the Chrome DevTools Utilities API copy   command for copying the string representation of the specified object to the clipboard   If you have lots of objects then you can actually JSON stringify   all your objects and keep on appending them to a string  Now use copy   method to copy the complete string to clipboard

There is an open-source javascript plugin that does just that - debugout js  Debugout js records and save console logs so your application can access them  Full disclosure  I wrote it  It formats different types appropriately  can handle nested objects and arrays  and can optionally put a timestamp next to each log  It also toggles live-logging in one place
