`microbundle-crl` uses old version of TS incompatible with template literal types

What happens and why it is wrong

I am using microbundle-crl for compiling my React TypeScript Project, compiling the code fails when I am using TypeScript Template Types like export type SpaceThemeProps = `$${keyof typeof theme['space']}` | (string & {})

Error

I get the following error when I run microbundle-crl --no-compress --format modern,cjs - semantic error TS2305: Module '"../../../../stitches.config"' has no exported member 'SpaceThemeProps'.

WorkAround

• I added the following in my package.json -

  "resolutions": {
      "**/typescript": "^4.1.5",
      "**/@typescript-eslint/eslint-plugin": "^4.15.1",
      "**/@typescript-eslint/parser": "^4.15.1"
    }
  

• Then I ran the following yarn add --dev typescript@latest @typescript-eslint/eslint-plugin@latest @typescript-eslint/parser@latest

And my build worked.

This is an issue with microbundle-crl, which has not been updated in ~2 years, not this plugin.

microbundle-crl uses an old version of this plugin under-the-hood, but this plugin does not specify a TS version, TS is listed as a peerDep. microbundle-crl, on the other hand, does specify an old TS version, specifically TS v3, before TS v4.

Closing as this is out-of-scope for this plugin and is a downstream issue in microbundle-crl, not here.
