That looks like a TypeScript import. What is the actual Node.js code it gets compiled to? Importing like this should work:
const FDBCursor = require("fake-indexeddb/lib/FDBCursor");
from fakeindexeddb.
It gets compiled to this:
"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
const FDBCursor = require("fake-indexeddb/lib/FDBCursor");
from fakeindexeddb.
I'm using following command to compile it:
tsc --skipLibCheck --target es6 --module commonjs --outDir ...
from fakeindexeddb.
Ah crap you're right, I get the same error even with my code! I'll look into this soon, thanks for the bug report.

Cool! Thanks for quick response! :)

You're right, it is related to circular imports. Probably nobody noticed it before because if you import fake-indexeddb first, it's not a problem. And there probably is not a reason to import FDBCursor without importing fake-indexeddb too.
So if you change from:
const FDBCursor = require("fake-indexeddb/lib/FDBCursor");
to:
const indexedDB = require("fake-indexeddb");
const FDBCursor = require("fake-indexeddb/lib/FDBCursor");
it will work. If you really have no use for the indexedDB
variable, you could also do:
require("fake-indexeddb");
const FDBCursor = require("fake-indexeddb/lib/FDBCursor");
I'd still like to fix this, but I'm just posting the workaround in case I don't get around to it for a while.

Thanks! It works this way.
About my use case: i'm writing custom testEnvironment for jest and want to extend this.global with fakeIndexedDB:
require("fake-indexeddb"); // workaround
import FDBCursor = require("fake-indexeddb/lib/FDBCursor");
import FDBCursorWithValue = require("fake-indexeddb/lib/FDBCursorWithValue");
import FDBFactory = require("fake-indexeddb/lib/FDBFactory");
...
export function makeIndexedDBEnv() {
return {
indexedDB: new FDBFactory(), // to not worry about resetting
IDBCursor: FDBCursor,
IDBCursorWithValue: FDBCursorWithValue,
...
}
}
class CustomEnvironment extends NodeEnvironment {
...
async setup() {
await super.setup();
const idbEnv = makeIndexedDBEnv();
Object.assign(this.global, idbEnv);
...
}
}
