npx doesn't run project-installed packages, it uses global downloads The "npm run" is a command for running defined scripts in your package.json The equivalent of "npm run" in yarn is just "yarn", for example: "yarn start"/"yarn dev". What "yarn run" does is allow you to run binaries installed from "dependencies"/"devDependencies". Say that I run the following: yarn install --dev nodemon ts-node typescript I can then run yarn run tsc --init / yarn run nodemon / yarn run ts-node And it will invoke the local "./node_modules" package binaries. This is useful when you want to ensure version-locked, per-project binaries.
