Deploying Git-Based npm Dependencies on Heroku

Other Questions NPM

Deploying my Node.js app with a Git-sourced dependency using npm on Heroku fails. Below is my module configuration:

{
  "project": "demo-app",
  "version": "1.0.0",
  "libs": {
    "utilModule": "git://github.com/anotheruser/new-lib.git#main"
  }
}

Any suggestions?

hey, i had similiar probs. using a commit-id instead of a branch fixed things for me. heroku sometimes caches old deps so double-check your git ref details. try ssh keys if permission errors come up.

Deploying a node app with a git-based npm dependency on Heroku can sometimes be unstable when using a branch reference. In my recent experience, switching to referencing a specific commit rather than a branch made the process significantly more reliable. This method locks down the dependency to a tested version, eliminating the unpredictability of branch updates. Additionally, I found that when I cleaned the build cache on Heroku before each deployment, it prevented potential conflicts from previous builds. This procedure helped maintain a consistent build environment, ultimately leading to smoother deployments.

In my experience, deploying Git-based npm dependencies to Heroku can be tricky. I encountered similar issues where specifying a branch led to intermittent failures during the build process. The solution that eventually worked for me was to include a commit hash in the dependency reference. This practice enforces a specific version and prevents potential issues with branch updates. It is also critical to ensure that the repository is public and does not require additional authentication. Verifying that the structure of the dependency repository complies with npm standards also helped resolve my deployment challenges.

I encountered similar deployment challenges and found that configuring the dependency in package-lock.json often resolves the issue. By ensuring the lock file carries the exact commit hash, Heroku reliably retrieves the intended version without ambiguity from branch updates. It is also beneficial to verify that npm is using an HTTPS URL instead of the git protocol, as network restrictions can sometimes impact access. In my case, this combination of adjustments led to a smoother deployment process on Heroku, providing more confidence in using Git-based dependencies.
