Use npm run -silent to reduce logs and to prevent the script from throwing an error. On failure, all logs are included in this file. The path to this file is provided at the end of the error message. Both can be useful for googling the error.Īnd if we need more information, we can always access the complete log file. When a script throws an error, we get a few other details, such as the error number errno and the code. To define an NPM script, all you need to do is set its name and write the script in the script property in your package.json file:Įnter fullscreen mode Exit fullscreen mode
You can also use these scripts in your CI/CD pipeline to simplify tasks like build and generate test reports. Their goal is to provide a simple way to execute repetitive tasks, like: NPM Scripts are a set of built-in and custom scripts defined in the package.json file. In this article, I'll share my research about how to take full advantage of NPM scripts.
That's when I decided to learn everything I could about NPM scripts and write this article. I've been using NPM Scripts for years, but I wanted to pass a parameter to a script a few weeks ago and realized I didn't know how to do that. But do you know all you can do with NPM Scripts? Is there another way to find if the installation is global? Or detect the usage of the -prefix option maybe?Ī few years ago, globalness was detected using ('global'), but it was changed in this commit that I don't understand.You may have come across the scripts property in the package.json file and even write some scripts yourself. prefix installationĪs a result, the installation is considered global on windows and not on linux. On windows, I cannot find a way to differentiate a -global installation from an installation with a -prefix, while it's easy on linux because the globalDir is defined differently. globalDir, '.' )Įspecially this part: this.where = path.resolve(npm.globalDir, '.') I develop using Vagrant on OS X or Linux.I don't use a proxy, but have limited or unreliable internet access.I use a proxy when downloading Git repos.I use a proxy to connect to the npm registry.test/package.json (should not have dependencies even though there is -save option passed) test/node_modules | grep lodash (should be there) How can the CLI team reproduce the problem? I guess the -prefix option is not applied to the -save option or something. command (plugin is removed from node modules but not from package.json). This happens only on windows machines (on mac and on linux it runs fine). The package installs, but it's NOT saved as a dependency in the package.json. Npm install -prefix path\to\package.json -save
