Creating your own command line interface(CLI) in Node.js and being able to use it from anywhere in the system provides agility and efficiency to your workflow. Learn the key steps to transform your CLI into a binary and easily install it on your machine using npm.
How to define the binary in the package.json file?
Essentially, the first thing is to edit your package.json file. Here, after the existing scripts section, you will add a new section called bin. This section will explicitly specify the name of the command and the file it will execute when invoked.
Be sure to follow these steps:
- Add the bin section.
- Choose a simple, clear name for your command, such as
platzi-assistant. - Point the command to the file to be executed, for example
ai-assistant. - Be sure to copy and paste exactly the name of the file to avoid errors.
Your package.json file should look similar to this:
{ "bin": { "platzi-assistant": "ai-assistant" }}How to install and use your CLI locally with npm link?
Once you have configured your package.json file, you are ready to install your CLI locally, for which you will use the npm link command.
Follow these simple steps:
- Make sure you are in the directory that contains your
package.jsonfile. - Run in your terminal:
npm linkAfter running this command, you will be able to use platzi-assistant from anywhere in your terminal without needing to be in a specific directory.
Don't forget that if your CLI requires an API key, such as the one mentioned for Gemini, you must make sure to set it before use.
Why publish your CLI in npm and how to do it?
Publishing your CLI package in npm allows you to use it globally or run it easily with npx without prior installations. You can install globally published packages by:
npm install -g package-nameOr run them temporarily without installation using the npx command:
npx package-nameExploring npm publishing can take the usability of your creations to another level. Consider checking out the specialized npm publishing course Platzi has available if you want to delve deeper into these topics.
