Microbundle: Directory name containing parenthesis causes TypeScript to not parse properly

Created on 6 Jun 2019 · 2Comments · Source: developit/microbundle

package.json:

{
  "name": "microbundle-bug",
  "main": "dist/test.js",
  "module": "dist/test.es.js",
  "types": "dist/test.d.ts",
  "source": "index.ts",
  "devDependencies": {
    "microbundle": "^0.11.0"
  }
}

index.ts:

function hello(name: string): string {
  return 'Hello ' + name;
}

console.log(hello('Daniel'));

Command I'm using:

.\node_modules\.bin\microbundle --format es,cjs --no-compress

In a directory name without parenthesis, it works:

C:\temp\microbundle-bug>.\node_modules\.bin\microbundle --format es,cjs --no-compress
node-resolve: setting options.module is deprecated, please override options.mainFields instead
node-resolve: setting options.jsnext is deprecated, please override options.mainFields instead
node-resolve: setting options.module is deprecated, please override options.mainFields instead
node-resolve: setting options.jsnext is deprecated, please override options.mainFields instead
Build "microbundleBug" to dist:
         93 B: test.js.gz
         68 B: test.js.br
         93 B: test.es.js.gz
         68 B: test.es.js.br

In a directory name WITH paranthesis, it fails to parse the TypeScript:

C:\temp\microbundle-bug (lol)>.\node_modules\.bin\microbundle --format es,cjs --no-compress
node-resolve: setting options.module is deprecated, please override options.mainFields instead
node-resolve: setting options.jsnext is deprecated, please override options.mainFields instead
