Should i commit node modules

This has many side effects. Switching between branches is slower. More importantly, it increases the amount of code you need to send between servers during your deploy process.

This can really increase deploy times. Deploys are harder! You'll have to npm rebuild on every machine to make sure native modules are compiled correctly. Running "heroku ps" confirms the crash. However, even after reverting, I still get the same error message on deploy, but now the application is running correctly again. Running "heroku ps" tells me the application is running. What's the right way to do this?

And why would I still be getting the error message when I rollback? My guess is the Git repository is in a bad state on the Heroku side. From the documentation of shrinkwrap :. The source listed for the below recommendation has been updated.

For packages you deploy, such as websites and apps, you should use npm shrinkwrap to lock down your full dependency tree:. Use npm to manage dependencies in your dev environment, but not in your deployment scripts.

Or npm might become corrupted; or the maintainers might decide to remove the library that you rely on from their repository; or the version you use might be trimmed out.

This can be mitigated with repository managers like Maven , because you can always use your own local Nexus Sonatype or Artifactory to maintain a mirror with the packages that you use. As far as I understand, such a system doesn't exist for npm. The same goes for client-side library managers like Bower and Jam. If you've committed the files to your own Git repository, then you can update them when you like, and you have the comfort of repeatable builds and the knowledge that your application won't break because of some third-party action.

See the Node. However, the original error looks to be an incompatibility between the versions of npm and Node. It is a good idea to always explicitly set the engines section of your packages.

I believe that npm install should not run in a production environment. There are several things that can go wrong - npm outage, download of newer dependencies shrinkwrap seems to have solved this are two of them. Apart from their big size, commits including them can become distracting. The best solutions would be this: npm install should run in a CI environment that is similar to the production environment.

All tests will run and a zipped release file will be created that will include all dependencies. Both solutions did not make me happy. And shrinkwrap. So it did not take me long to implement this idea in a Node. It will calculate the hash of your package. Explicitly adding a npm version to file package. It may be slower to deploy since it downloads the packages each time , but I couldn't get the packages to compile when they were checked in. Heroku was looking for files that only existed on my local box.

The package. Heroku can then tell npm to install all of those dependencies. The tutorial you linked to contains a section on package. The era of global modules is dead. The original link was this one , but it is now dead. Thanks Flavio for pointing it out. If you have native modules that should be build for specific platform then create a separate repository for each platform. You use a package that gets removed from npm.

If you do only have the package name in the package. If a package is less than 24 hours old, you can easily remove it from npm. If it's older than 24 hours old, then you need to contact them. If you contact support, they will check to see if removing that version of your package would break any other installs. If so, we will not remove it. You develop an enterprise version of your software or a very important software and write in your package. Now the developers of studpid-package rename the method function1 x to function2 x and they make a fault They change the version of their package from 1.

That's a problem because when you call npm install the next time, you will accept version 1. A few kb package. Think about it. This will work because of how NodeJS CommonJS modules system works by moving up to the parent directory, and so on, until the root of the tree is reached. See: Make. Avoiding putting. A pull request or merge if changing the dependencies, is going to have much more files involved in the process.

Tools become slower or even decide to not show the full diff GitHub, for example. Native node modules need to be recompiled if you deploy to a platform different than your development machine common use case: you develop on Mac, deploy on Linux. You need to call npm rebuild , which takes the server out of sync. Tip: there is no need to use the specific version in your package. An npm package might be removed by its author from the npm registry.

It happened with the famous left-pad incident in read more.
