I have another question (last question). At the moment i am working on a Node.js project and in this I have many console.log() functions. This has worked okay so far but I also want everything that's written to the console to also be written in a log-file. Can someone please help me?
For example:
Console.log('The value of array position [5] is '+ array[5]);
In my real code its a bit more but this should give you an idea.
Thank you hopefully.
Just run the script in your terminal like this...
node script-file.js > log-file.txt
This tells the shell to write the standard output of the command node script-file.js
to your log file instead of the default, which is printing it to the console.
This is called redirection and its very powerful. Say you wanted to write all errors to a separate file...
node script-file.js >log-file.txt 2>error-file.txt
Now all console.log
are written to log-file.txt
and all console.error
are written to error-file.txt
