If you’re a developer, chances are you’ve used NPM to install packages for your projects. But have you ever wondered what else NPM can do? In this article, we’ll explore some of the lesser-known features of NPM that will help streamline your workflow and boost productivity.
Get rid of the command line in your workflow.
The command line is a powerful tool for developers, but it’s not the best fit for every workflow. If you’re just getting started with Node.js or building an app from scratch, it can be helpful to use a code editor that has built-in terminal support so you don’t need to switch back and forth between applications.
If your code editor doesn’t have built-in terminal support yet, don’t worry! There are plenty of plugins available on npm (the package manager used by NodeJS) that add this functionality quickly and easily–whether it’s through integrated terminals or by adding custom commands right into your text editor of choice.
Use package-lock.json to keep track of outdated dependencies.
The package-lock.json file is a JSON object that describes a package. It’s used to keep track of outdated dependencies, and can be created with npm install. The file name is usually in the root directory of your project, but it doesn’t have to be there–it just has to be somewhere in your project directory tree (or any directory).
If you have multiple projects using the same version of an npm module, then create one package-lock.json for all those projects by running this command:
npm install –save –only=dev@latest -g
Then run `npm cache clean` before making changes so that all changes will be reflected in both packages!
Install packages on a per-project basis.
Npm is a powerful tool that can be used to install packages on a per-project basis. This means you don’t have to install the same package for every project, which saves time and effort. For example, if you are using MomentJS in one project and MomentJS isn’t needed in another project, then there’s no need to install it again.
There are four different ways in which you can use npm:
- npm install –save-dev – Installs dependencies
- npm install –save – Installs dependencies and saves them as devDependencies in package.json file (default behavior)
Run npm init from inside a folder to create an empty package.json file
The npm init command is a command-line tool that helps you create a package.json file. It asks you questions and fills in the answers into a package.json file.
You can run npm init from any folder, but it’s best to do so in an empty directory that will be your project folder (it does not have to be called `package`). For example:
npm init
Create a custom/global ignore file for .gitignore
If you’re working with a team, it’s likely that everyone will have their own .gitignore file in their project. The problem is that when you pull down someone else’s project or clone it, their .gitignore files will be added to your local copy. This can make things confusing if you’ve already created one for yourself and don’t want them overwritten by the global ignore file from another user on your team. To get around this issue, create a custom global ignore file at the root level of your project directory:
- Create a new file called “.global-ignores” (with no extension). This will become your custom global ignore file which will override any other ones in existence as long as they are not named “.global-ignores”.
