v4.6.0 module has no exports about togeojson HOT 10 CLOSED

Bizarre, thanks for pointing this out. Not much has changed in between - might be a rollup regression.

I'm having a lot of trouble replicating this error. Importing directly from the esm file, using webpack… I can't find a setup that has this error. The dist files on npm look normal and mostly unchanged. Can you share anything about your setup or a repro case that'd help me debug? Thanks!

Yeah, here's what my package.json looks like

  }

Running npm install installs @tmcw/[email protected] as expected.
Node is version 17.3.0
NPM is version 8.3.0

Looking in /node_modules/@tmcw/togeojson/dist/togeojson.js the exports are definitely there, but for some reason, it does not like it.

from togeojson.

The relevant code in my handler file is:

import { kml } from '@tmcw/togeojson'

const domParser = new DOMParser()
const parsedKML = domParser.parseFromString(reader.result, 'text/xml')
let geojson = kml(parsedKML, { styles: true })

from togeojson.

I am getting the error too using require:
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: [....\node_modules]()@tmcw\togeojson\dist\togeojson.js
require() of ES modules is not supported.

from togeojson.

I am having the same issues, both with loaders.gl/kml, and @tmcw/togeojson.

togeojson.js is treated as an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which declares all .js files in that package scope as ES modules.
Instead rename togeojson.js to end in .cjs, change the requiring code to use dynamic import() which is available in all CommonJS modules, or change "type": "module" to "type": "commonjs" in /path/to/project/node_modules/@tmcw/togeojson/package.json to treat all .js files as CommonJS (using .mjs for all ES modules instead).

NPM: 8.5.2
NodeJS: v10.19.0

@tmcw/togeojson": "^4.5.0

from togeojson.

Okay, it was the type: "module" field, which opens a real can of worms. Introduced 4.6.1, which renames main to .cjs and adds an export field in package.json to direct users to that. Any luck with that?

I installed the update and things looks good thus far. Will reply back if I find any issues.

👍 Okay, let me know if anyone encounters any other issues.

Looks good, thanks!
