A tool that handles compressing, bundling, and unpacking production node_modules dependencies that you want to store in source control
Produndle is a project that brings pac back to life (and support modern versions of Node.js. To achieve the fastest deployments possible, the production node_modules/ (not devDependencies or any of that optional stuff) can be compressed by running produndle pack and stored in source control. Then, when deployment time comes all you have to do is uncompress or run produndle unpack. This works well when you also run node-prune on your node_modules/ folder, before compressing your production dependencies. We even take it a step further in some cases and create global shared configurations for libraries like ESLint and Prettier that dynamically load their plugins into node_modules/ by downloading compressed plugins from source control without having to run npm install. We fuss about the performance of our node_modules/ installation time because it is often a bottleneck.
If you are simply including this library in your project, all you need is a recent version of Node.js. Node.js >14.18.0 is sometimes required and is the only version range we actively support. Albeit, it is highly probable that lower versions will work as well depending on the requirements that this project imports.
The following versions of Node.js and Python are required for development:
Other versions may work, but only the above versions are supported. Most development dependencies are installed automatically by our Taskfile.yml set-up (even Node.js and Python). Run bash start.sh to install Bodega (an improved fork of go-task) and run the initialization sequence. The taskfiles will automatically install dependencies as they are needed, based on what development tasks you are running. For more information, check out the CONTRIBUTING.md or simply run:
npm run helpnpm run help will ensure Bodega is installed and then open an interactive dialog where you can explore and learn about various developer commands.
After ensuring your node_modules/ folder only contains the files you want in your compressed, production packages, simply run:
produndle packThis will create compressed .tgz files for each of the packages in the node_modules/ folder. You can then save these in source control or wherever you like. The compressed files will be stored in the .modules/ folder.
When you are ready to deploy your compressed packages, perhaps after freshly cloning your repository, just run:
produndle unpackBefore compressing your production node_modules/, you might want to take a couple steps to ensure that only what is needed is present in the node_modules/ folder.
Start off by clearing your node_modules/ folder:
rm -rf node_modulesThen, install only the dependencies by running:
npm install --only=prodNext, ensure node-prune is installed and use it to remove unnecessary files from the node_modules/ folder by running:
node-pruneAt this point, you should check the size of the node_modules/ folder and ensure that it is a modest size. If it is not and you still want to keep your production node_modules/ in your source control repository, then you might want to consider wiping the history of the .modules/ folder periodically. You can follow the instructions here, replacing rm -rf node_modules with rm -rf .modules.
The node_modules/ folder can get pretty big, pretty quickly, so you might want to consider saving your .modules to an S3 bucket. You can get really fancy with it and actually bind the .modules folder in your project to an S3 Fuse mount using software like goofys. If you are interested, check out our free Ansible role for goofys.
You can get even fancier with it by doing things like dynamically loading your node_modules/. Sometimes you might have a library that only needs a dependency sometimes. In that case, you can download the compressed .tgz wherever it is stored and load it on-demand. You can load a single module by running a command similar to this one:
produndle unpack eslintFor the above snippet to work, you would have to have the compressed eslint.tgz file stored in .modules/eslint.tgz.
For even more performance, consider using pnpm. Although we use pnpm normally, we actually use npm for building the node_modules/ folder that Produndle compresses. You can get a better idea of how we implement Produndle by checking out this Taskfile.yml which is powered by our custom task-runner called Bodega.

Sponsorship
Dear Awesome Person,
I create open source projects out of love. Although I have a job, shelter, and as much fast food as I can handle, it would still be pretty cool to be appreciated by the community for something I have spent a lot of time and money on. Please consider sponsoring me! Who knows? Maybe I will be able to quit my job and publish open source full time.
Sincerely,
Brian Zalewski
