A utility to fetch or build patched Node binaries used by pkg to generate executables. This repo hosts prebuilt binaries in Releases.

We do not expect this project to have vulnerabilities of its own. Nonetheless, as this project distributes prebuilt Node.js binaries,
Node.js security vulnerabilities affect binaries distributed by this project, as well.
Like most of you, this project does not have access to advance/private disclosures of Node.js security vulnerabilities. We can only closely monitor the public security advisories from the Node.js team. It takes time to build and release a new set of binaries, once a new Node.js version has been released.
It is possible for this project to fall victim to a supply chain attack.
This project deploys multiple defense measures to ensure that the safe binaries are delivered to users:
- Binaries are compiled by Github Actions
- Workflows and build logs are transparent and auditable.
- Artifacts are the source of truth. Even repository/organization administrators can't tamper them.
- Hashes of binaries are hardcoded in source
- Origins of the binaries are documented.
- Changes to the binaries are logged by VCS (Git) and are publicly visible.
pkg-fetchrejects the binary if it does not match the hardcoded hash.
- GPG-signed hashes are available in Releases
- Easy to spot a compromise.
pkg-fetchpackage on npm is strictly permission-controlled
- Only authorized Vercel employees can push new revisions to npm.
Contributing Updates to Patches
Example workflow for applying patches to a new version of Node.js (18.13.0)
- Clone Node.js as a sibling to your current
git clone https://github.com/nodejs/node.git
- Checkout the tag you wish to generate a patch for
git checkout v18.13.0
- Attempt to apply the closest patch (e.g. applying the existing patch for 18.12.1 when trying to generate a new patch for 18.13.0)
git apply ..\pkg-fetch\patches\node.v18.12.1.cpp.patch --reject
- If no rejects, great! you are ready to make your new patch file.
git add -A
git diff --staged --src-prefix=node/ --dst-prefix=node/ > ..\pkg-fetch\patches\node.v18.13.0.cpp.patch
- If rejects exist, resolve them yourself, and ensure all changes are saved, and repeat step 4 to export the patch file
Usually when a patch is rejected, it's because the context around the changes
was refactored slightly since the last patched version. This is not usually
complicated to resolve, but requires a human to interpret the changes since the
pkg was patched against, compared with the version you wish to
create a patch for.
One method is to pull up the diff for the file where the rejects apply for the
changes between the last tag (e.g. v18.12.1 to use the previous example) and the
tag you want a patch for (e.g. v18.13.0 to use the previous example). Alongside
this, have the
.rej file and go through each rejected hunk by hunk and use
your best judgement to determine how it should apply against the new tag.
Save you results, and export the overall git diff with the commands from the example above.
Checking that patches apply cleanly
The expectation is that a patch applies cleanly, with no delta or offsets from the source repo.
When making a change to a patch file, it is possible to apply that patch without building by running
yarn applyPatches --node-range node18
--node-range can be specified to apply patches for the version of
node for which you are updating patches. If unspecified, the latest node version
in patches.json will be used.
Ultimately, the patch should result in fully functional node binary, but the
applyPatches script can be used to quickly iterate just the application of
the patches you are updating without needing to wait for the full build to
Building a Binary Locally
You can use the
yarn start script to build the binary locally, which is helpful
when updating patches to ensure functionality before pushing patch updates for
yarn start --node-range node18 --arch x64 --output dist
