import-local

What is import-local?

The import-local npm package is designed to allow a globally installed package to defer to a locally installed version of itself when it is being run within a project that has that package as a dependency. This is useful for testing local changes to a package without having to publish the package or modify the global version.

What are import-local's main functionalities?

Deferring to local version

This code checks if a local version of the package is available. If it is, it will use the local version and log a message to the console. Otherwise, it will proceed with the global package's code.

if (importLocal(__filename)) {
  console.log('Using local version of this package');
} else {
  // Code for the global package goes here
}

Other packages similar to import-local

resolve-from

The resolve-from package allows you to resolve a module path from a given root directory. It's similar to import-local in that it helps with module resolution, but it doesn't automatically defer to a local version of a package.

require-local

Require-local is another package that allows for requiring modules from a local context. It's similar to import-local but does not provide the automatic deferring mechanism to local versions when a global version is run.

linklocal

Linklocal can link local dependencies for development purposes. It's similar to import-local in that it helps with using local versions of packages, but it works by creating symlinks rather than deferring when a global version is executed.
