To create an npm library, follow these concise steps:
1. **Install Node.js and npm**: Ensure you have Node.js installed, which includes npm.
2. **Create a New Directory**: Make a folder for your library (e.g., `my-library`).
3. **Initialize the Package**:
– Run `npm init -y` to create a package.json without inputs.
– Add necessary scripts like `”start”` or `”test”` in package.json.
4. **Write Your Library Code**: Create a main file (e.g., `index.js`) to export functions.
5. **Install Dependencies**:
– Use `npm install` for any required packages.
– Include testing frameworks like Jest for functionality tests.
6. **Test the Library**: Write test cases in `index.test.js` and run them using `npm test`.
7. **Publish to npm**:
– Get an npm token from [npm’s website](https://www.npmjs.org/).
– Run `npm publish` in your library directory to make it public.
8. **Use the Library**:
– Install it in other projects with `npm install my-library`.
– Import and use functions from the library using `import myLibrary from ‘my-library’;`.
9. **Manage Updates**: Use semantic versioning for releases (e.g., 1.0.0, 1.1.0) and update packages via npm commands.
10. **Ensure Security**: Use tools like ESLint or audit with `npm audit` to check vulnerabilities.
By following these steps, you can create, test, and share your own npm library efficiently.
