PyPI Package Disguised as Instagram Growth Tool Harvests User Credentials
A deceptive PyPI package posing as an Instagram growth tool collects user credentials and sends them to third-party bot services.
The ultimate solution of writing asyncronous code in a beautiful way.
npm install rush
var rush = require('rush');
var fs = require('fs');
rush({
n: 0
data: []
})(function() {
this.n++;
fs.readFile('file1.txt', this(function(data) {
this.data.push(data);
}));
fs.readFile('file2.txt', this(function(data) {
this.data.push(data);
}));
})(function() {
this.n++;
fs.readFile('file3.txt', this(function(data) {
this.data.push(data);
}));
})(function(err) {
if (err) {
// Handle the error.
return;
}
console.log(n); // => 2
// this.data should have 3 items:
// (data of) file1, file2, file3 or file2, file1, file3.
})();
You can use multiple initializers (passing of an object to Rush), but all these objects will be used like as you passed a single merged object at the beginning of the chain.
Don't rely on such behaviour, it will be fixed later.
rush({
x: 2
})(function() {
console.log(x); // Logs 3, but not 2!
})({
x: 3
})(function() {
console.log(x); // Logs 3 as intended.
})(function(err) {
check(!err);
})();
You can use regular blocks instead of initializers, as blocks are executed strictly one after another (if there are no errors in them).
