Supply Chain Attack Detected in @solana/web3.js Library
A supply chain attack has been detected in versions 1.95.6 and 1.95.7 of the popular @solana/web3.js library.

Advanced tools
The array-series npm package allows you to run an array of asynchronous functions in series, meaning one after the other, where each function waits for the previous one to complete before starting.
Run asynchronous functions in series
This feature allows you to run an array of asynchronous functions in series. Each function in the array takes a callback function as its argument, which it calls when it has completed its task. The next function in the array will not start until the previous one has called its callback.
const series = require('array-series');
const tasks = [
function (done) {
setTimeout(function () {
console.log('Task 1');
done();
}, 1000);
},
function (done) {
setTimeout(function () {
console.log('Task 2');
done();
}, 500);
},
function (done) {
setTimeout(function () {
console.log('Task 3');
done();
}, 100);
}
];
series(tasks, function (err) {
if (err) throw err;
console.log('All tasks completed');
});
The async package provides a wide range of utilities for working with asynchronous JavaScript. It includes methods for running functions in series, parallel, and other control flow patterns. Compared to array-series, async offers more flexibility and additional features such as error handling, queue management, and more.
The run-series package is similar to array-series in that it allows you to run an array of asynchronous functions in series. However, run-series is part of a suite of small modules for asynchronous control flow, which can be used together for more complex workflows.
The promise-series package allows you to run an array of functions that return promises in series. This package is useful if you prefer working with promises instead of callbacks. It provides a similar functionality to array-series but leverages the power of promises for better readability and error handling.
Call an array of asynchronous functions in series
var series = require('array-series')
series([
function (done) {
done()
}
], this, function (err) {
})
fns
is an array of functions to call in series.
The argument signature should be:
function (done) {
done(new Error())
// or
done()
}
That is, each function should only take a done
as an argument.
Each callback should only take an optional Error
as an argument.
Optional context to pass to each fn
.
Basically fn.call(context, done)
.
function (err) {
}
Only argument is an Error
argument.
It will return the first error in the series of functions that returns an error,
and no function after will be called.
