Express 4 : Sync vs. Async When you first start writing Express, error handling is very easy. That’s because with synchronous code, Express wraps your route logic in a hidden try/catch under the hood: app.get(‘/sync-crash’, (req, res) => {throw new Error(“Oops!”); }); When an error is thrown synchronously, Express intercepts it and forwards it directly […]

Most penetration tests work the same way. You hire a company, they bill you for the hours spent by their researchers and you pay up front. Whether or not they find a critical problem, the bill is the same. This model is not designed to detect dangerous vulnerabilities. It is designed to provide a signed […]
What is CommonJS (CJS)? Back in 2009, when Node.js was created to run JavaScript on servers, outside of browsers, the language had a huge flaw: it didn’t have a built-in system for sharing code between files.
