In most cases, you should not commit this folder into your version controlled repository. As you install more dependencies, the size of this folder will quickly grow. Furthermore, the package-lock. While the package. With your package. Now copy the package. If no lock file is available, it would read from the package. It is usually quicker to install from package-lock. When deploying to production, you may want to skip the development dependencies.
Recall that development dependencies are stored in the devDependencies section of package. The --production flag ignores the devDependencies section during installation.
For now, stick with your development build. So far, you have been installing npm modules for the locator project. This means that the package is available to your user in the wider system, like any other shell command. This ability is useful for the many Node.
To do so, you can use a library like Hexo to create and manage your static website blog. Install the Hexo CLI globally like this:. Note : If you get a permission error trying to install this package globally, your system may require super user privileges to run the command. Try again with sudo npm i hexo-cli -g. So far, you have learned how to install modules with npm. You can install packages to a project locally, either as a production or development dependency.
You can also install packages based on pre-existing package. Now that you can install modules, in the next section you will practice techniques to administer your dependencies. A complete package manager can do a lot more than install modules. In this step, you will:. While these examples will be done in your locator folder, all of these commands can be run globally by appending the -g flag at the end of them, exactly like you did when installing globally.
If you would like to know which modules are installed in a project, it would be easier to use the list or ls command instead of reading the package. To do this, enter:. By default, ls shows the entire dependency tree—the modules your project depends on and the modules that your dependencies depend on.
To only print the modules you installed without their dependencies, enter the following in your shell:. The --depth option allows you to specify what level of the dependency tree you want to see. It is a good practice to keep your npm modules up to date. This improves your likelihood of getting the latest security fixes for a module.
Use the outdated command to check if any modules can be updated:. The Wanted column shows which version satisfies your version requirement in package. The Latest column shows the most recent version of the module that was published. The Location column states where in the dependency tree the package is located. The outdated command has the --depth flag like ls. By default, the depth is 0. It seems that you can update eslint to a more recent version.
Use the update or up command like this:. The npm uninstall command can remove modules from your projects. Removing dependencies from a project is a normal activity in the software development lifecycle. A dependency may not solve the problem as advertised, or may not provide a satisfactory development experience. In these cases, it may better to uninstall the dependency and build your own module. Imagine that axios does not provide the development experience you would have liked for making HTTP requests.
Uninstall axios with the uninstall or un command by entering:. To verify that it was uninstalled, list the dependencies once again:. To see the audit in action, install an outdated version of the request module by running the following:. To get more details, audit your entire project with:. You can see the path of the vulnerability, and sometimes npm offers ways for you to fix it.
You can run the update command as suggested, or you can run the fix subcommand of audit. In your shell, enter:. However, you still have four vulnerabilities in your dependencies. The audit fix command does not always fix every problem. Although a version of a module may have a security vulnerability, if you update it to a version with a different API then it could break code higher up in the dependency tree. You can use the --force parameter to ensure the vulnerabilities are gone, like this:.
In this tutorial, you went through various exercises to demonstrate how Node. In a Node. You also used the npm CLI tool to install, update, and remove modules, in addition to listing the dependency tree for your projects and checking and updating modules that are outdated.
You will also be able to create your own npm modules, and these will in turn will be managed by others via npm commands. As for next steps, experiment with what you learned in this tutorial by installing and testing the variety of packages out there. See what the ecosystem provides to make problem solving easier. For example, you could try out TypeScript , a superset of JavaScript, or turn your website into mobile apps with Cordova.
The Node runtime is commonly used for back-end web development, leveraging its asynchronous capabilities to create networking applications and web servers. Node also is a popular choice for building command line tools. In this series, you will go through exercises to learn the basics of how to code in Node.

Prerequisites To complete this tutorial, you will need: Node. This tutorial uses version To install this on macOS or Ubuntu By having Node. Step 1 — Creating a package. Using the init Command First, set up a project so you can practice managing modules.
In your shell, create a new folder called locator : mkdir locator Then move into the new folder: cd locator Now, initialize the interactive prompt by entering: npm init Note : If your code will use Git for version control, create the Git repository first and then run npm init. You will receive the following output: Output. Next in series: How To Create a Node. About the authors. Stack Abuse. Kick things off with the command auto-install and it should add the dependencies to the package.

I still don't get why npm install can't look at package-lock. Oh good. Do you mind if I add it as an answer then for you to accept? Ok go ahead. Technically your solution doesn't really answer the original question since it looks like auto-install doesn't even need package-lock. Add a comment. Active Oldest Votes.
