Introduction to npm-name

The npm-name library is an essential tool for any JavaScript developer looking to check the availability of package names on the official NPM registry. This library simplifies the process of validating package names before publishing them, ensuring your project name is unique and follows NPM guidelines.

Basic Usage

To get started with npm-name, first install the package using npm:

npm install npm-name

Check a Single Name

Use the following code snippet to check the availability of a single package name:

const npmName = require('npm-name');
(async () => {
    console.log(await npmName('unicorn'));
    //=> false
})();

Multiple Name Checks

You can also check multiple names at once by passing an array of names:

const npmName = require('npm-name');
(async () => {
    console.log(await npmName.many(['chalk', 'np', 'abc123']));
    // [{name: 'chalk', available: false}, {name: 'np', available: true }, {name: 'abc123', available: true}]
})();

Name Properties

The package also returns additional information about names, like scope support:

const npmName = require('npm-name');
(async () => {
    const name = await npmName('private-package');
    console.log(name);
    /*
    { 
      name: 'private-package',
      available: true,
      scope: true
    };
    */
})();

App Example Using Introduced APIs

Here’s a small example of a node app that checks for NPM package name availability and stores the results:

const npmName = require('npm-name'); const fs = require('fs');
const packageNames = ['express', 'react', 'vue', 'angular']; const results = [];
(async () => {
    for (const name of packageNames) {
        const availability = await npmName(name);
        results.push(availability);
    }

    fs.writeFileSync('package-name-results.json', JSON.stringify(results, null, 2));
    console.log('Results saved to package-name-results.json');
})();

In this example, we check the availability of several popular package names and save the results to a JSON file.

Using npm-name in your own projects can save you time and prevent potential conflicts, ensuring a smooth development process.

Conclusion

npm-name is a straightforward yet powerful tool for anyone who publishes packages to the NPM registry. By integrating its APIs into your workflow, you can quickly and efficiently verify package names, streamline your publishing process, and avoid naming conflicts.

Happy coding and happy publishing!
