Finding the right node package
Since there are so many packages we have a problem of plenty. For any given scenario we have multiple packages and it becomes difficult to identify the right fit for your use case. I generally look up github repos of popular projects to finalise which package to use. This may not scale up always and need more work.
So I have stuck to using http://npms.io/ for now. It has better search features and also has rating of various packages based on different parameters. You can read the rating logic on https://npms.io/about
For example if you want to use
twitter api packages you can search for the same which gives you an output like
Do let me know if there is a curated list of node packages or some help groups which help us identify the right packages.
Using additional features of npm
If you are a node developer I am pretty sure that you have already used npm and you are comfortable with the popular commands
npm init and
npm install So let us look at a few other handy commands and features.
Since there are more than 7,00,000 packages in node I wanted to make sure that there was a simple way to keep track of my favourite packages. There seems to be a way but not very user friendly.
Create an account on https://www.npmjs.com/
From the interface I didn’t find any option to start my favorite packages. For now looks like we will have to make do with
Login on command line with your credentials.
One you hit the command enter your credentials. Currently it asks for email id which is public. I think npm figures out a way to mask the user email ids. I am not comfortable sharing my email id.
Once you are logged in, you can checkout if it was successful using the
Starring a package
npm star axios
If you want a list of packages you have starred then you can use
The command gives you the output like show in the above image.
Most of the packages in npm have dependencies on other libraries and that is a good thing. It means that packages are modular. For example if you are using axios(https://www.npmjs.com/package/axios) package you can checkout https://www.npmjs.com/package/axios?activeTab=dependencies see the packages axio is using. If you want to see different packages that are using axios you can checkout https://www.npmjs.com/package/axios?activeTab=dependents
If you want the complete dependency list you can use
npm list which gives a tree output like below.
Most of the times this is overwhelming and the first level packages should be a good enough check.
npm list --depth=0 2>/dev/null
If you use the above command you will get the list of first level packages in your project.
To go global or not
As a rule of thumb I have tried to reduce the number of packages I install globally. It always makes sense to install the packages locally as long as they are related to the project. I only consider installing a package globally if its utility is beyond the project or has nothing to do with the project. You can run the following command to see your list of globally installed packages.
npm list -g --depth=0 2>/dev/null
In my case the output is
As you can see from the list most of the packages are general purpose and have got nothing to do with individual projects. I am not sure why I installed jshint globally. My atom editor is setup with jshint and I think that should be sufficient. I will spend some time over the weekend to see why I did that.
In latest npm versions if there are any security concerns they get displayed when you run
npm install command. But if you want to do an audit of your existing packages run
This command gives you details of vulnerabilities in the package. It gives you details of the path so that you can judge the potential damage if any. If you want more details you can checkout the node security advisory.
You can run a command like
npm update fsevents?—?depth 3 to fix the individual vulnerabilities as suggested or you can run
npm audit fix to fix all the vulnerabilities at once like I did.
