ESM incompatibility due to round-to (direct dependency)

First of all thank you for providing and esm export but unfortunately it’s not working as expected because round-to (a direct dependency) isn’t an esm module itself.

Error:

SyntaxError: Importing binding name 'default' cannot be resolved by star export entries.

See reproduction here (capsize): https://esm.codes/#aW1wb3J0IGNhcHNpemUgZnJvbSAnaHR0cHM6Ly91bnBrZy5jb20vY2Fwc2l6ZSc7Cgpjb25zdCBzdHlsZXMgPSBjYXBzaXplKHsKICBjYXBIZWlnaHQ6IDE2LAogIGxpbmVHYXA6IDgsCiAgZm9udE1ldHJpY3M6IHsKICAgIGNhcEhlaWdodDogNzAwLAogICAgYXNjZW50OiAxMDU4LAogICAgZGVzY2VudDogLTI5MSwKICAgIGxpbmVHYXA6IDAsCiAgICB1bml0c1BlckVtOiAxMDAwLAogIH0sCn0pOwoKY29uc29sZS5sb2coInN0eWxlczogIiwgc3R5bGVzKTs=

or

import capsize from 'https://unpkg.com/capsize';

const styles = capsize({
  capHeight: 16,
  lineGap: 8,
  fontMetrics: {
    capHeight: 700,
    ascent: 1058,
    descent: -291,
    lineGap: 0,
    unitsPerEm: 1000,
  },
});

console.log("styles: ", styles);

or

import roundTo from 'https://unpkg.com/round-to';

console.log("round: ", roundTo(1.234, 2));

Be careful not to use a cdn like cdn.skypack.dev it will look like it’s working because they magically translate non esm module into esm module on the fly, see here:

or

import roundTo from 'https://cdn.skypack.dev/round-to';

console.log("round: ", roundTo(1.234, 2));

Will be removing the dependency in favour of internalising the function as part of an upcoming PR.
