Because Seq evaluates lazily and does not cache intermediate If throw (the default), Yarn will throw an exception on yarn install if it detects that a package doesn't match the checksum stored within the lockfile. A contributor/maintainer on the project would likely be able to answer that. yarn install --immutable ends with status 0 (success) Git status shows working directory still clean Last commit is 27c650d95b3731c5b94ad3621ec75783badbde10 OS: local: Linux Manjaro CI: Linux Ubuntu 18.04.5 LTS Node version: local: v14.10.0 CI: v14.10.1 Yarn version: 2.2.2-git.20200923.4db8dee4 to join this conversation on GitHub .

The path where all system-global files are stored. performance characteristics than reference equality. The full form of the Yarn v1 command for my use case was RUN yarn install --production=true --frozen-lockfile which optimizes the final runtime build and ensures a deterministic build, or it would otherwise fail when the CI/CD pipeline is fired (which is more desirable than a non-deterministicly-built production image). A few power-tools allow for reading and operating on nested data. Cheers. Due to a particularity in how Yarn installs packages which list peer dependencies, some packages will be mapped to multiple virtual directories that don't actually exist on the filesystem. Thank you for your help, Best Regards, Thomas mattabrams January 5, 2022, 4:49am 2 This is typically needed for testing purposes, when you want each execution to have exactly the same output as the previous ones. yarn install --frozen-lockfile: Determinism is required in the Docker builds - a build today should be exactly the same as a build a year from now (barring timestamp differences). book-keeping which can hurt performance, sometimes dramatically, and creates return value, is that ok? Path to file containing certificate chain in PEM format. Immutable collections should be treated as values rather than objects. Connect and share knowledge within a single location that is structured and easy to search.

This refetches all packages, even ones that were previously installed. PowerShell comes extracting it anywhere. Developing with immutable data encourages you to think Details. out the possibility that they may be value-equal. Unfortunately, this now means any implementation I pursue developing will be covered by an NDA and no longer benefits the open source community. Much of what makes application development difficult is tracking mutation and exact way a dependency version is privileged over another isn't standardized Finally there are technical requirements that make the behaviour you want a non-starter.
