Import a module like with require() but from a given path (for ESM)
Import a module like with
require()but from a given path (for ESM)
This library intends to be an almost drop-in replacement of import-from (from which it is forked), exposing the same API and behavior but also supporting ES modules (ESM). Just add await before importFrom/importFrom.silent
The main benefit of using import-from is that it abstracts the need to resolve the path and create a require statement. Its code is really straightforward:
(fromDirectory, moduleId) => createRequire(path.resolve(fromDirectory, "noop.js"))(moduleId);
In the case of import-from-esm, there are a few additional benefits because of the way ESM works:
import.meta.resolve, which is behind an experimental flag (although there's a ponyfill available at wooorm/import-meta-resolve, which import-from-esm uses under-the-hood).require (while the former is still in experimental).import-from-esm re-introduces require's file extension discovery.As you can see, there is quite a bit of complexity that is abstracted behind import-from-esm. The first bullet point issue affected both @semantic-release/commit-analyzer and @semantic-release/release-notes-generator. After spending hours on research to solve the issue, I realized that the work I was doing would benefit others as well, so I decided to create a package out of it.
As a proponent of ESM, I have put a lot of thought into poly-filling require features for import, but finally came to the conclusion that developing a package to facilitate the ecosystem transition to ESM by reducing friction was a good thing.
$ npm install import-from-esm
import importFrom from "import-from-esm";
// there is a file at `./foo/bar.{js,mjs,cjs,json}`
await importFrom("foo", "./bar");
Like require(), throws when the module can't be found.
Returns undefined instead of throwing when the module can't be found.
Type: string
Directory to import from.
Type: string
What you would use in require().
Create a partial using a bound function if you want to import from the same fromDir multiple times:
const importFromFoo = importFrom.bind(null, "foo");
importFromFoo("./bar");
importFromFoo("./baz");
