You probably use, or at least have heard of,
Here are some commands I run on the reg with npx:
npx okimdone npm install
If you have your volume up, a voice will tell you when the command you entered is done. It's really handy for tasks that take ages but want to come back to after.
npx npm-check # Options -u - Interactive Updates -y - Update everything -s - Skip unused -g - Global
Checks your installed npm packages and gives you info about them. It's great for seeing if you have stuff in your package.json that your aren't actually using in your app.
npx npm-check -su will simply update all of your packages.
Run this from the folder that holds all of your projects. It will list out every node_modules folder from there along with the amount of disc space it is using. You can then go through them and delete the node_modules folders individually by hitting the space bar.
If you are creating components for react, this is really useful.
Generact will duplicate a component you already have made and give it a new name. It will copy the old components file structure and change the component name anywhere it is written inside it.
Just thought this was neat.
If you know of any more npx tools that are super useful, bung em in the comments.
