Manage IO operations in Node.js using direct style (sync code like) without callbacks. It works with generators under the hood.
const asyncFlow = require('asyncflow-gen');
asyncFlow(function* (callback) {
yield fs.writeFile('./test/testFile', 'Hey there!', callback);
const data = yield fs.readFile('./test/testFile', 'utf8', callback);
console.log('data is: ', data);
yield fs.unlink('./test/testFile', callback);
console.log('That is all, folks! Where are the callbacks??');
});
fs.writeFile('./test/testFile', 'Hey there!', err => {
if (err) {
handleErrorFunction(err);
}
fs.readFile('./test/testFile', 'utf8', (err, data) => {
if (err) {
handleErrorFunction(err);
}
console.log('data is: ', data);
fs.unlink('./test/testFile', err => {
if (err) {
handleErrorFunction(err);
}
console.log('That is all, folks! Yes, I do not like this callback cascade.');
});
});
});
