There are a number of things you can do to speed up npm:

• Use the latest version of npm: Npm is constantly being updated with new features and performance improvements. Make sure you are using the latest version of npm to get the best possible performance.
• Use a package manager mirror: Npm downloads packages from the default npm registry, which can be slow at times. You can use a package manager mirror to download packages from a faster server. Some popular package manager mirrors include npmjs.eu and npmmirror.镜像站.
• Use the --offline flag: If you are not connected to the internet, you can use the --offline flag to install packages from your local cache. This will be much faster than downloading the packages from the npm registry.
• Use the --no-audit flag: The audit command checks for security vulnerabilities in your installed packages. This can be a slow process. If you are not concerned about security vulnerabilities, you can use the --no-audit flag to skip the audit step.
• Use a different package manager: There are a number of alternative package managers available, such as Yarn and pnpm. These package managers can be faster than npm for certain tasks.

Here are some additional tips for speeding up npm:

• Clean the npm cache: The npm cache can become cluttered over time, which can slow down npm. You can clean the npm cache using the following command:

npm cache clean

• Use a package manager lockfile: A package manager lockfile is a file that specifies the exact versions of all of the packages installed in your project. This can help to speed up npm installs by preventing npm from having to download the latest versions of all of your packages every time you run npm install. To generate a package manager lockfile, you can use the following command:

npm install --package-lock-only

• Use a build tool: A build tool can help to automate the process of installing and building your project’s dependencies. This can help to speed up the development process and reduce the number of times you need to run npm install. Popular build tools include Webpack and Rollup.

I hope this helps!
