Package Exports

@yarnpkg/plugin-exec

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@yarnpkg/plugin-exec) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

`@yarnpkg/plugin-exec`

This plugin will instruct Yarn to execute the specified script and use its output as package content.

The script will be invoked with one parameter which is a temporary directory. You're free to do whatever you want inside, but at the end of the execution Yarn will expect a build directory to have been created inside it that will then be compressed into an archive and stored within the cache.

Busting the cache is currently unsupported - you'll need to manually remove the relevant archives from your cache each time you want to update the content of the package. Help welcome!

Install

yarn plugin import @yarnpkg/plugin-exec

Usage

package.json

{
  "dependencies": {
    "pkg": "exec:./gen-pkg.js"
  }
}

gen-pkg.js

const {mkdirSync, writeFileSync} = require(`child_process`);
const generatorPath = process.argv[2];

mkdirSync(`${generatorPath}/build`);

writeFileSync(`${generatorPath}/build/package.json`, JSON.stringify({
  name: `pkg`,
  version: `1.0.0`,
}));

writeFileSync(`${generatorPath}/build/index.js`, `module.exports = ${Date.now()};\n`);
