This seems like a solved problem but I am unable to find a solution for it.
Basically, I read a JSON file, change a key, and write back the new JSON to the same file. All works, but I loose the JSON formatting.So, instead of:
{
name:'test',
version:'1.0'
}
I get
{name:'test',version:'1.1'}
Is there a way in Node.js to write well formatted JSON to file ?

JSON.stringify
's third parameter defines white-space insertion for pretty-printing. It can be a string or a number (number of spaces). Node can write to your filesystem withfs
. Example:See the JSON.stringify() docs at MDN, Node fs docs
