See original GitHub issueDescribe the bug
I’m trying to use lodash-es
like this:
import { debounce } from 'lodash-es'
//...debounce using it
but I’m getting the below error.
Logs
1:37:22 AM [vite] Error when evaluating SSR module /src/routes/players/_cmp/SearchBar.svelte:
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: C:\kit\node_modules\lodash-es\lodash.js
require() of ES modules is not supported.
require() of C:\kit\node_modules\lodash-es\lodash.js from C:\kit\node_modules\vite\dist\node\chunks\dep-e9a16784.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.
Instead rename lodash.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from C:\kit\node_modules\lodash-es\package.json.

Wow. All this is scary!
For now I’m using
import debounce from 'lodash/debounce.js'
instead ofimport { debounce } from 'lodash-es'
.@frederikhors I’ve had issues with
lodash-es
and have worked around the issue by sticking with version4.17.15
instead of the latest4.17.21
in the interim. I believe esm compatibility is a known issue with lodash.I’ve also had issues with
d3-format
and have stayed on2.0.0
instead of3.0.0
