Snowpack warning: import.meta is not available

[rmrbytes]

I am placing this warning that showed up only as a matter or record. I have not found any problem in the use of the library under the Snowpack environment (I needed to test my project in another bundle environment because webpack was giving me some problems).

The warning showed up during the build process of Snowpack:

> _snowpack/pkg/@zipjs/zipjs.js: warning: "import.meta" is not available in the configured target environment and will be empty
    4843 │     workerData.worker = new Worker(new URL(workerData.scripts[0], import.meta.url));
         ╵                                                                   ~~~~~~~~~~~

Thanks

Thank you for the information. I guess this is the same issue than FredKSchott/snowpack#2513.

The fix would be to set target to es2020 in your config file.

This seems to break in Webpack 4 too

You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

@shadow-light Did you try to install https://www.npmjs.com/package/@open-wc/webpack-import-meta-loader? see #212 (comment)

Thanks for suggestion. I just imported '@zip.js/zip.js/dist/zip' instead to save time.
