yarn up

This command upgrades the packages matching the list of specified patterns to their latest available version across the whole project (regardless of whether they’re part of dependencies or devDependencies - peerDependencies won’t be affected). This is a project-wide command: all workspaces will be upgraded in the process.

If -R,--recursive is set the command will change behavior and no other switch will be allowed. When operating under this mode yarn up will force all ranges matching the selected packages to be resolved again (often to the highest available versions) before being stored in the lockfile. It however won’t touch your manifests anymore, so depending on your needs you might want to run both yarn up and yarn up -R to cover all bases.

If -i,--interactive is set (or if the preferInteractive settings is toggled on) the command will offer various choices, depending on the detected upgrade paths. Some upgrades require this flag in order to resolve ambiguities.

The, -C,—caret, -E,—exact and -T,—tilde options have the same meaning as in the add command (they change the modifier used when the range is missing or a tag, and are ignored when the range is explicitly set).

If the —mode= option is set, Yarn will change which artifacts are generated. The modes currently supported are:

• skip-build will not run the build scripts at all. Note that this is different from setting enableScripts to false because the latter will disable build scripts, and thus affect the content of the artifacts generated on disk, whereas the former will just disable the build step but not the scripts themselves, which just won’t run.

• update-lockfile will skip the link step altogether, and only fetch packages that are missing from the lockfile (or that have no associated checksums). This mode is typically used by tools like Renovate or Dependabot to keep a lockfile up-to-date without incurring the full install cost.

Generally you can see yarn up as a counterpart to what was yarn upgrade --latest in Yarn 1 (ie it ignores the ranges previously listed in your project’s manifests), but unlike yarn upgrade which only upgraded dependencies in the current workspace, yarn up will upgrade all workspaces at the same time.

This command accepts glob patterns as arguments (if valid Descriptors and supported by micromatch). Make sure to escape the patterns, to prevent your own shell from trying to expand them.

Note: The ranges have to be static, only the package scopes and names can contain glob patterns.

Options

Option	Description
--fixed	Store dependency tags as-is instead of resolving them
--exact	Don’t use any semver modifier on the resolved range
--tilde	Use the ~ semver modifier on the resolved range
--caret	Use the ^ semver modifier on the resolved range
--mode	Change what artifacts this install will generate
