如何更新 package.json 和 package-lock.json 文件中的所有包？

Question

I have a website and I haven't updated it for about a year. I need to update all the packages in "package.json" and "package-lock.json" and I have no clue how to do it. I would be grateful for any suggestion. The Node version I'm using is 16.15.1 LTS.

You can update packages in package.json with these steps:

1- Navigate to the root directory of your project and ensure it contains a package.json file:

cd /path/to/project

2- In your project root directory, run the update command:

npm update

3-To test the update, run the outdated command. There should not be any output.

npm outdated

And for package-lock.json follow these steps:

1- Delete your package-lock.json file in the root directory of your project,

2- Simply run npm install as in default, it checks if your directory has package-lock.json file otherwise, it will create one for you. (This command will honour the ^ and ~ symbol and update the packages to its latest that is provided by the library author(s)).

Information about ^ and ~:

In package.json , a version can have a ^ in front (eg ^0.12.31), meaning the latest minor release may be safely installed.

Tilde (~) in front (eg, ~0.12.31) means the latest patch release is safe to install.
