pnpm 10.0.0 Blocks Lifecycle Scripts by Default
pnpm 10 blocks lifecycle scripts by default to improve security, addressing supply chain attack risks but sparking debate over compatibility and workflow changes.
The has-yarn npm package is a simple utility that checks if a project is using Yarn as its package manager by looking for a 'yarn.lock' file in the project directory. It is useful for tooling and scripts that need to adapt their behavior based on the package manager being used.
Check if Yarn is being used
This feature allows you to check if a project is using Yarn by invoking the hasYarn function. It returns true if a 'yarn.lock' file is found in the project directory, indicating that Yarn is being used.
const hasYarn = require('has-yarn');
if (hasYarn()) {
console.log('The project uses Yarn.');
} else {
console.log('The project does not use Yarn.');
}
yarn-or-npm is a more versatile package that can detect whether Yarn or npm is being used in a project. It can return 'yarn' or 'npm' based on the lock file detected, providing a direct comparison to the singular focus of has-yarn.
