chore: add strict npmrc by 43081j · Pull Request #7229 · netlify/build

43081j · 2026-09-15T16:23:42Z

Adds a basic .npmrc which enables:

strict-allow-scripts=true - means scripts which are not in allowScripts will fail npm i rather than only showing a warning
min-release-age=7 - sets a minimum age of 7 days for packages to be installed

📝 Summary

Summary by CodeRabbit

Chores
- Updated package installation safeguards to require dependencies to be published for at least two days, while exempting approved scoped packages.
- Continued enforcing strict allowlisting for package installation scripts, including approved build-related dependencies.
- Updated the required npm version to 11.17.0 or later.
- npm now stops execution when the required version is not met, rather than displaying a warning and continuing.
- Standardized automated build and test environments on npm 11.
- Added installation permissions for approved dependency build scripts in relevant build and test environments.

Walkthrough

The npm configuration now requires packages to be at least two days old and exempts @netlify/* packages. Strict script allowlisting remains enabled. The repository requires npm >=11.17.0 and fails when the requirement is unmet. Package metadata and test fixtures allow specified install scripts. CI workflows install npm 11 before dependency installation.

Full details: Description check

Explanation

The description explains the strict script allowlisting, but it is incomplete and inaccurate. The changes set min-release-age to 2 days, exempt @netlify/* packages, update npm requirements, add allowlists, and install npm 11 in workflows. The description states a 7-day age requirement and does not describe these additional changes.

Resolution

Update the description to match the implemented configuration. State the 2-day min-release-age, the @netlify/* exemption, the allowed packages, the npm version enforcement, and the workflow changes. Add the issue reference and update the checklist if applicable.

Pin the npm version installed by every workflow.

npm install -g npm@11 resolves a moving npm 11 release on every run. This can change dependency installation, tests, benchmarks, and publication behavior without a repository change. Pin one exact tested version that satisfies the repository requirement, such as npm@11.17.0.

@coderabbitai unfortunately we can't use onFail: "error" (yet) because installing node in CI with a cache enabled actually calls npm config ... which will throw before we have chance to bump npm to the chosen one.

tracked in actions/setup-node#1553

coderabbitai · 2026-09-17T12:18:53Z

Tip

For best results, initiate chat on the files or code changes.

@43081j Thanks for the clarification. onFail: "warn" is required while cached actions/setup-node invokes npm config ... before the workflow installs npm 11. I withdraw the concern about using onFail: "error".

Learning: In `netlify/build`, keep `package.json` `devEngines.packageManager.onFail` set to `"warn"` until `actions/setup-node` changes its cache behavior. With caching enabled, `actions/setup-node` runs `npm config ...` before the workflow installs npm 11, so `"error"` causes setup to fail when the runner starts with an unsupported npm version. This is tracked by actions/setup-node#1553.

chore: add strict npmrc

50e7058

Adds a basic `.npmrc` which enables: - `strict-allow-scripts=true` - means scripts which are not in `allowScripts` will fail `npm i` rather than only showing a warning - `min-release-age=7` - sets a minimum age of 7 days for packages to be installed
