The recent changes to publish
@php-wasm/node
as ESM broke the.wasm
files paths in the published package. Specifically,__dirname + '/php_8_0.wasm'
became/home/runner/work/wordpress-playground/wordpress-playground/node_modules/@php-wasm/node/php_8_0.wasm
which is undesirable.This PR polyfills the
__dirname
variable with ESM-compliant alternatives in the ESM version of the@php-wasm/node
package.Testing instructions
npm run build
@php-wasm/node
package has the correct.wasm
files paths.
