Convert worker to ESM (#500) * Convert worker to ESM To use ESM for the worker, I created a package.json file in worker/ with `{ type: "module" }` as its sole content. I then rewrote every import to use ESM syntax. I also tried to set `{ type: "module" }` in the root package.json file to also use ESM in next.config.js. However, this resulted in a weird problem: default imports were now getting imported as objects in this shape: `{ default: <defaultImport> }`. Afaik, this should only be the case if you use "import * as foo from 'bar'" syntax: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import#default_import This is fixed by not using `{ type: "module" }` for some reason. However, then, next.config.js also doesn't support ESM import syntax anymore. The documentation says that if you want to use ESM, you can use next.config.mjs: https://nextjs.org/docs/pages/api-reference/next-config-js But I didn't want to use MJS extension since I don't have any experience with it. For example, not sure if it's good style to mix JS with MJS etc. So I kept the CJS import syntax there. * Ignore worker/ during linting I wasn't able to fix the following errors: /home/runner/work/stacker.news/stacker.news/worker/auction.js:0:0: Parsing error: No Babel config file detected for /home/runner/work/stacker.news/stacker.news/worker/auction.js.
