JS from Scratch #39 | NPM Scripts: How to Automate Routine and Deploy Any GitHub Project
Why do programmers write custom automation commands, how to turn the terminal into a chain of shortcuts, and how to bring a project downloaded from the internet to life in 2 seconds? Taming NPM scripts.
⠀
🔹 IN THIS VIDEO:
We continue our detailed exploration of the Node.js ecosystem and conclude the most important lesson of the previous lesson. You will learn how to program your own process automation within the scripts object and uncover the main secret of developer collaboration on the GitHub platform.
⠀
🔹 THE MAGIC OF THE SCRIPTS OBJECT (KEY-VALUE):
We will analyze the structure of the package.json configuration file and breathe life into an empty script block. Using practical examples, we will create:
Custom createfold shortcut: You will see how to make NPM execute system commands (for example, creating folders with mkdir) directly from the context of your project.
The main start shortcut: We'll set up a command to automatically launch our node index.js application. You'll learn why running the start script doesn't require npm run, but rather the simple npm start command.
⠀
🔹 HOW TO WORK WITH OTHER PEOPLE'S CODE AND DOWNLOADED REPOSITORIES:
We'll conduct a rigorous experiment—we'll completely remove the node_modules folder from our project, causing a "Module not found" error. You'll see how, thanks to the package.json file and its dependencies section, any codebase can be deployed on a computer from scratch with just one command:
npm install
The utility will automatically contact the central repository and download absolutely all the necessary libraries (including our Moment.js) in their current versions. ⠀
