Cannot import d3-geo in node with typescript

[sardounis]

It seems I have an issue of importing the library using nodejs 14 and typescript.

I have used @types/d3-geo as well.

Though I am getting the error: An unexpected error occurred Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /Users/antonissardounis/Projects/beat/bhs-cf/functions_new/functions/node_modules/d3-geo/src/index.js\nrequire() of ES modules is not supported.\nrequire() of /Users/antonissardounis/Projects/beat/bhs-cf/functions_new/functions/node_modules/d3-geo/src/index.js from /Users/antonissardounis/Projects/beat/bhs-cf/functions_new/functions/lib/utils/Geo/Geo.js is an ES module file as it is a .js file whose nearest parent package.json contains \"type\": \"module\" which defines all .js files in that package scope as ES modules.\nInstead rename index.js to end in .cjs, change the requiring code to use import(), or remove \"type\": \"module\" from /Users/antonissardounis/Projects/beat/bhs-cf/functions_new/functions/node_modules/d3-geo/package.json.\n\n at new NodeError (internal/errors.js:322:7)\n at Object.Module._extensions..js (internal/modules/cjs/loader.js:1102:13)\n at Module.load (internal/modules/cjs/loader.js:950:32)\n at Function.Module._load (internal/modules/cjs/loader.js:790:12)\n at Module.require (internal/modules/cjs/loader.js:974:19)\n at require (internal/modules/cjs/helpers.js:101:18)\n at /Users/antonissardounis/Projects/beat/bhs-cf/functions_new/functions/lib/utils/Geo/Geo.js:33:75\n at processTicksAndRejections (internal/process/task_queues.js:95:5)\n at async Geo.init (/Users/antonissardounis/Projects/beat/bhs-cf/functions_new/functions/lib/utils/Geo/Geo.js:33:27)\n at async Geo.AreCoordinatesInsideGeofence (/Users/antonissardounis/Projects/beat/bhs-cf/functions_new/functions/lib/utils/Geo/Geo.js:39:9) {\n code: 'ERR_REQUIRE_ESM'\n}"}

it seems there is an open issue at stack overflow as well: link

any updates on this?

[bennoinbeta]

ok my mistake.. I didn't import it as namespace :)

// index.ts
import * as d3Geo from 'd3-geo'

// compiled index.js
const d3Geo = require('d3-geo')

[bennoinbeta]

ok the esmodule import via import * as d3Geo from 'd3-geo' only works with 2.0.2 but not with the latest one 3.1.0 :/

this works for me:

d3Geo = await import("d3-geo");

[bennoinbeta]

yeah but dynamic imports aren't that nice.. so I'll stick to the 2.x.x for now :)
