yarn upgrade

Upgrades packages to their latest version based on the specified range.

yarn upgrade [package | package@tag | package@version | --scope @scope]... [--ignore-engines] [--pattern]

This command updates dependencies to their latest version based on the version range specified in the package.json file. The yarn.lock file will be recreated as well.

Optionally, one or more package names can be specified. When package names are specified, only those packages will be upgraded. When no package names are specified, all dependencies will be upgraded.

[package] : When a specified package is only a name then the latest patching version of this package will be upgraded to.

[package@tag] : When a specified package contains a tag then the specified tag will be upgraded to. Tag names are chosen by project maintainers, typically you use this command to install an experimental or long term support release of an actively developed package. The tag you choose will be the version that appears in your package.json file.

[package@version] : When a specified package contains a version then the specified version will be upgraded to. The package.json dependency reference will also be changed to match this specified version. You can use any SemVer version number or range.

--ignore-engines : This flag can be used to skip the engines check.

Examples:

yarn upgrade
yarn upgrade left-pad
yarn upgrade left-pad@^1.0.0
yarn upgrade left-pad grunt
yarn upgrade @angular

yarn upgrade --pattern <pattern> will upgrade all packages that match the pattern.

Examples:

yarn upgrade --pattern gulp
yarn upgrade left-pad --pattern "gulp|grunt"
yarn upgrade --latest --pattern "gulp-(match|newer)"

yarn upgrade [package]... --latest|-L [--caret | --tilde | --exact] [--pattern]

The upgrade --latest command upgrades packages the same as the upgrade command, but ignores the version range specified in package.json. Instead, the version specified by the latest tag will be used (potentially upgrading the packages across major versions).

The package.json file will be updated to reflect the latest version range. By default, the existing range specifier in package.json will be reused if it is one of: ^, ~, <=, >, or an exact version. Otherwise, it will be changed to a caret (^). One of the flags --caret, --tilde or --exact can be used to explicitly specify a range.

Examples:

yarn upgrade --latest
yarn upgrade left-pad --latest
yarn upgrade left-pad grunt --latest --tilde

yarn upgrade (--scope|-S) @scope [--latest] [--pattern]

--scope @scope : When a scope is specified, only packages that begin with that scope will be upgraded. A scope must begin with ‘@’.

--latest : Ignores the version range specified in package.json. Instead, the version specified by the latest tag will be used (potentially upgrading the packages across major versions).

Examples:

yarn upgrade --scope @angular
yarn upgrade -S @angular
