.pnpmfile.cjs
pnpm позволяет подключаться непосредственно к процессу установки с помощью специальных функций (хуков). Хуки могут быть объявлены в файле .pnpmfile.cjs
.
По умолчанию .pnpmfile.cjs
должен быть расположен в том же каталоге, что и лок-файл. Например, в рабочем пространстве (воркспейсе) с общим лок-файлом, .pnpmfile.cjs
должен находиться в корне монорепо.
Хуки
TL;DR
Хук-функция | Process | Uses |
---|---|---|
hooks.readPackage(pkg, context): pkg | Called after pnpm parses the dependency's package manifest | Allows you to mutate a dependency's package.json |
hooks.afterAllResolved(lockfile, context): lockfile | Called after the dependencies have been resolved. | Allows you to mutate the lockfile. |
hooks.readPackage(pkg, context): pkg | Promise<pkg>
Allows you to mutate a dependency's package.json
after parsing and prior to resolution. These mutations are not saved to the filesystem, however, they will affect what gets resolved in the lockfile and therefore what gets installed.
Note that you will need to delete the pnpm-lock.yaml
if you have already resolved the dependency you want to modify.
If you need changes to package.json
saved to the filesystem, you need to use the pnpm patch
command and patch the package.json
file. This might be useful if you want to remove the bin
field of a dependency for instance.
Аргументы
pkg
- The manifest of the package. Either the response from the registry or thepackage.json
content.context
- Context object for the step. Method#log(msg)
allows you to use a debug log for the step.
Использование
Example .pnpmfile.cjs
(changes the dependencies of a dependency):
function readPackage(pkg, context) {
// Override the manifest of foo@1.x after downloading it from the registry
if (pkg.name === 'foo' && pkg.version.startsWith('1.')) {
// Replace bar@x.x.x with bar@2.0.0
pkg.dependencies = {
...pkg.dependencies,
bar: '^2.0.0'
}
context.log('bar@1 => bar@2 in dependencies of foo')
}
// This will change any packages using baz@x.x.x to use baz@1.2.3
if (pkg.dependencies.baz) {
pkg.dependencies.baz = '1.2.3';
}
return pkg
}
module.exports = {
hooks: {
readPackage
}
}
Известные ограничения
Removing the scripts
field from a dependency's manifest via readPackage
will not prevent pnpm from building the dependency. When building a dependency, pnpm reads the package.json
of the package from the package's archive, which is not affected by the hook. In order to ignore a package's build, use the pnpm.neverBuiltDependencies field.
hooks.afterAllResolved(lockfile, context): lockfile | Promise<lockfile>
Позволяет изменять вывод локфайла до его сериализации.
Аргументы
lockfile
- The lockfile resolutions object that is serialized topnpm-lock.yaml
.context
- Context object for the step. Method#log(msg)
allows you to use a debug log for the step.
