One of the really cool, less known and typically forgotten features of NPM and Yarn is the ability to install git repositories directly as part of the package install command.
Whether you are working on a serverside javascript project using NodeJS or a client-side application using any of the build tools such as Webpack, Gulp or even, good old Grunt, you might come to the point where you need to use a private or public GitHub repository as a dependency in your
package.json
.Here, we will be going over how to reference a Github repo as one of the modules in your package.json. We will start with a public repo and then go over how you can set it up using a private repo.
1. Using a Public Repository as a Dependency
The general syntax for installing a package directly from GitHub follows the structure below. You will note that this is the process for installing the package via the command-line.
$ npm@4 -version (stderr) npm@4 not found. Trying with npx. 4.6.1 $ asdfasdfasf zsh: command not found: asfdasdfasdf Currently, zsh, bash (= 4), and fish are supported. You can access these completion scripts using npx -shell-auto-fallback. The command npm view express dependencies shows only direct dependencies, but i can't figure out how to view its complete dependencies tree. – sof Aug 10 '15 at 16:28 8 only works if you have the module installed into a nodemodules folder. Doesn't do you any good if you're trying to resolve a dry run. – worc Oct 12 '18 at 22:02.
Semantic Versioning Npm
To use the GitHub repo as a dependency in your
package.json
, you can use the following syntax below:For public repositories, the syntax listed above works for all

Npm is awesome as a package manager. In particular, it handles sub-dependencies very well: if my package depends on request version 2 and some-other-library, but some-other-library depends on request version 1, the resulting dependency graph looks like.

Love, Marriage & Divorce is a collaborative studio album by American recording artists Toni Braxton and Babyface, released on February 4, 2014, by Motown Records. On Love, Marriage & Divorce, Toni Braxton and Babyface, creative partners going back to the early '90s, rekindle their musical relationship.Both endured broken marriages, and presumably it's those experiences that inform the material here - a succinct collection of 11 songs, eight of which are duets.

2. Using a Private Repository as a Dependency
When it comes to using a private repository as a module in your
package.json
. The syntax and the idea are very similar to the public version, the main change is that a form of authentication is added to the git syntax. Iqiyi mac. There are 2 approaches to achieve this form of authentication, namely using HTTPS and SSH.2.a. Using a HTTPS
The first approach here is to use a special GitHub system user with access to the repository and generate an access token for this user that can be used directly as basic authentication in the HTTPS call.
To do that go to Settings >Developer settings on GitHub. There, you can select the Personal access tokens and click Generate new token. Once you define the scopes for the token you can use this token in
package.json
as follows:Be sure to select the types of access the system user needs. Typically, you would want to give only read access to the system user to limit risk. We will talk more about the downsides to using this approach later.
Once you have successfully added the token to your package.json, You can now delete your
node_modules
and then run npm install
command. This should install the package from the GitHub repo.Set a light 3d studio serial number. The main disadvantage and obvious downside of this approach is that you are required to commit the token, however, as long as it’s for a private repository and you created a special read-only system account for this, you should be ok. There are actually various situations where using the SSH approach we are going to discuss next is not possible to do, an example is when you run NPM install within Docker containers or in environments where you cannot use SSH keys.
2.b. Using SSH
The second approach is very similar to the public option discussed in point #1 above, it just uses SSH for authentication. In this case, the URL to reference does not need any token like in the code sample below.
For this SSH approach to work, you need to be sure you have access to this particular repository and you have generated SSH keys for yourself or the user account that’s going to run this install in Settings >SSH and GPG keys. Follow the guide on GitHub on how to set up SSH keys.
Even though the SSH option is clearly more secure and should be the preferred approach whenever you need to do this. There might be a case where the token works better or is the only option available. Exterminate it activation key.

As a developer I am lazy. I don’t build everything by myselfbecause others have done it already. Vhs to video converter. So, when I come upon a problem someone has already solved and that someoneput that solution into some library, I simply pull that library into my own - I declare a dependency to that library.
This post describes an important caveat when declaring “soft” dependencies using NPM and how to lock these dependenciesto avoid problems.
package.json
In the javascript world, NPM is the de-facto standard package manager which takes care of pulling mydependencies from the web into my own application. Those dependencies are declared in a file called
package.json
and look like this (example from an angular app):Unstable Dependencies
Toast 17 pro torrent mac free. In the
package.json
you can declare a dependency using certain matchers:'4.2.4'
matches exactly version 4.2.4'~4.2.4
matches the latest 4.2.x version'^4.2.4
matches the latest 4.x.x version'latest'
matches the very latest version'>4.2.4'
/'<=4.2.4'
matches the latest version greater than / less or equal to 4.2.4)*
matches any version.
Matchers like
~
and ^
provide a mechanism to declare a dependency to a range of versions instead of a specific version. This can be very dangerous, since the maintainer of your dependency might update to a version that does no longer workwith your application. The next time you build your app, it might fail - and the reasons for that failure will bevery hard to find.Stable Dependencies with package-lock.json
Each time I create a javascript app whose dependencies are managed by NPM, the first thing I’m doing is to remove all matchers in
package.json
and define the exact versions of the dependencies I’m using.Sadly, that alone does not solve the “unstable dependencies” problem. My dependencies can have their own dependencies.And those may have used one of those matchers to match a version range instead of a specific version. Thus, even thoughI declared explicit versions for my direct dependencies, versions of my transitive dependencies might changefrom one build to another.
To lock even the versions of my transitive dependencies to a specific version, NPM has introduced package locks with version 5.
When calling
npm install
, npm automatically generates a file called package-lock.json
which contains alldependencies with the specific versions that were resolved at the time of the call. Future calls of npm run build
will then use those specific versions instead of resolving any version ranges.Simply check-in
package-lock.json
into version control and you will have stable builds.Not Working?
NPM doesn’t generate a
package-lock.json
? Or the versions in package-lock.json
are not honored when callingnpm run build
? Make sure that your NPM version is 5 or above and if it isn’t, call npm install npm@latest
(you may also provide a specific version to npm install
, if you prefer :)).Npm Install
