Frequently asked questions
What is a package.json file?
A package.json file is the central manifest for any Node.js or JavaScript project. It stores project metadata, lists external dependencies, and defines command-line scripts to build, run, and test the project.
Do I need Node.js or npm installed to use this tool?
No, this generator runs entirely in your web browser. You can generate, edit, and download a valid configuration file without installing Node.js, npm, or any terminal tools on your computer.
Is the package.json generator free?
Yes, this tool is completely free to use with no account creation or subscription required.
What is the difference between dependencies and devDependencies?
Dependencies are packages required for your application to run in production, such as web frameworks or utility libraries. DevDependencies are packages only needed during local development and testing, such as linters, bundlers, and testing frameworks.
Does this tool store my project information?
No, all input handling and JSON generation take place locally within your browser session. Your project details are not uploaded, stored, or tracked on external servers.
