Checking if writeFileSync successfully wrote the file
javascript, node.js
Solution
According to node.js source-code `fs.writeFileSync` doesn't return anything.
It throws an `Error` object if something goes wrong. So you should write `fs.writeFileSync(file, content, 'utf8');` within a `try-catch` block.
Problem
I have a simple route defined with `express.js`: ``` exports.save = function (request, response) { var file = request.body.file; var content = request.body.content; var saved = false; if (fs.existsSync( file )) { saved = fs.writeFileSync(file, content, 'utf8'); } console.log( saved ); // undefined or false, never true response.send(saved ? 200 : 500, saved ? 'saved' : 'error'); // 500, error }; ``` Is `if (typeof saved === 'undefined') saved = true;` the only option? Feels hacky.
