Methods

attachCustomData

attachCustomData(customData: unknown): void

- Defined in packages/yarnpkg-core/sources/Installer.ts:79
Only called if the installer has a custom data key matching one currently stored. Will be called with whatever finalizeInstall returned in its customData field.

Parameters
- customData: unknown
Returns void

attachExternalDependents

attachExternalDependents(locator: Locator, dependentPaths: Array<PortablePath>): Promise<void>

- Defined in packages/yarnpkg-core/sources/Installer.ts:125
Link a package to the location of the external packages that depend on it (only the location is available, since two linkers should be generic enough to not have to make custom integrations).

Will never be called for packages supported by the same linker (they'll be linked through the attachInternalDependencies hook instead).

This function is guaranteed to be called for all packages before the install is finalized.
