package.json and package-lock.json are both files used in Node.js projects to manage dependencies, but they serve different purposes and have different roles in the development workflow. Let's explore the differences between these two files:
package.json:
package.json is a mandatory configuration file in Node.js projects. It contains metadata about the project, such as its name, version, description, author, scripts, and more.
One of the key roles of package.json is to list the project's dependencies and devDependencies. These are the external packages and libraries that your project relies on to run and develop properly.
You typically define the required packages along with their versions in the dependencies and devDependencies sections of the package.json file.
package.json is manually maintained by the developer and can be updated when you add, update, or remove dependencies using package managers like npm or yarn.
package-lock.json:
package-lock.json (or yarn.lock if using Yarn) is an automatically generated file that provides a detailed, deterministic lock on the versions of dependencies installed in your project.
It was introduced to address the issue of "dependency hell," where differences in dependency versions between developers' machines could lead to inconsistent behavior.
The purpose of package-lock.json is to ensure that the same dependencies are installed consistently across different environments
package-lock.json is a lockfile that contains information about the dependencies/packages with their exact version numbers (*important) that were installed for a node.js project.
Should you commit your package-lock.json?
Yes, this file should be committed to the source repository so that when developers clone your repoPlease do like share and comment if you like the video please do hit like and if you have any query please write it comment box
