Phantomjs append to file with fs.write

Question

How can I append to a file using fs.write()?

Using fs.write on the same files overwrites the content:

var fs = require(\'fs\');
try {
    fs         


        

Answer 1

Use append mode a instead of [over]write mode w in the fs.write call.

var fs = require('fs');
try {
    fs.write("file.txt", "Hello World", 'a');
    fs.write("file.txt", "Hello World", 'a');
} catch(e) {
    console.log(e);
}

I inferred this based on the python open() C fopen documentation; Glad it worked, other file modes may work but were not tested by me.
