Using plugin-exec with arguments

[Sharakai]

Background

I've been trying out using plugin-exec in my work project, for more complex non-npm dependencies. To be precise: Git repositories containing schema files which we later generate TypeScript bindings for.

It's working perfectly for cloning the repository, creating a "fake" package.json, and only re-exec'ing the script when the file changes. It's providing a lot of benefit with caching and only running "postinstall" when the dependencies change, etc.

Problem

I have to create a separate script for each git repository I would like to clone rather than being able to re-use a shared script for each exec:-schema dependency.

If I could provide arguments / environment variables to the script, then I could re-use the same script and just initialise it differently for each dependency.

Examples

Current:

Currently, I have something that looks akin to

"devDependencies": {
  "schema-one": "exec:./schema-fetch/schema-one.mjs",
  "schema-two": "exec:./schema-fetch/schema-two.mjs",
}

Where each file is identical aside from some initial variable setup at the top of the file, e.g:

const REPO_URL = "git@github.com:sharakai/schema-one.git";
const VERSION = "0.12.34";

Desired

Syntax is entirely open to ideation.

"devDependencies": {
  "schema-one": "exec:./fetch-schema.mjs -- repo=git@github.com:sharakai/schema-one.git version=0.12.34",
  "schema-two": "exec:./fetch-schema.mjs -- repo=git@github.com:sharakai/schema-two.git version=1.23.4",
}

Notes

I can't use the Git/GitHub protocols as no manifest exists in the repository
