Those two flags only enable local file access via XHR, you still have to know the exact path to the file and you can't write anything. It would be less tricky and more secure to just handle file i/o with native code.
@feronull @jarek-foksa. Ok thanks for the info. I agree with jarek-foksa it is still a bit tricksy and I would prefer to access the file i/o with native code. What does it means ? Do I need to build my own "file i/o" lib in c to interface with it ? Does it exist somewhere ? Would you have an example ? Many thanks
This is already done in Brackets, you could just copy/paste the code from https://github.com/adobe/brackets-app/blob/master/src/win/ce... and https://github.com/adobe/brackets-app/blob/master/src/win/ce... as it's under MIT license.
With the bridge in place you can access files from JavaScript as follows:
brackets.fs.readFile('path/to/file.txt', 'utf-8', function(file) {
console.log(file);
});
