Dexie.js: Table.where() errors with "Cannot read property 'bound' of undefined"

Question

I'm having some troubles getting where() statements to work in Dexie. My attempts to use where result in the following error:

  console.warn node_modules/dexie/dist/dexie.js:1273
    Unhandled rejection: TypeError: Cannot read property 'bound' of undefined
        at makeIDBKeyRange (node_modules/dexie/src/dbcore/dbcore-indexeddb.ts:112:21)
        at node_modules/dexie/src/dbcore/dbcore-indexeddb.ts:314:31
...

Here's the code that I used:

import Dexie from "dexie";
// @ts-ignore there is not a type for the fake indexeddb
import indexedDB from 'fake-indexeddb';

class TestDatabase extends Dexie {
  constructor() {
    super("test");
    this.version(1).stores({
      data: "id, name"
    });
  }
}

test("dexie", async ()=>{
  Dexie.dependencies.indexedDB = indexedDB;
  const db = new TestDatabase();
  await db.table("data").put({id: "x", name: "xname"});
  const x=await db.table("data").get("x");
  expect (x.name).toEqual("xname");

  const x2=await db.table("data").where("id").equals("x").toArray()
  expect (x2[0].name).toEqual("xname");
})

The test appears to be failing at the call to toArray(). How can I get this test to pass?

Try removing .toArray() it looks like that's for passing a callback. — AJcodez

I think you're missing to set Dexie.dependencies.IDBKeyRange also.

Fake-indexeddb recommends to do the following to integrate fake-indexeddb in node:

const Dexie = require("dexie");
require("fake-indexeddb/auto");

const db = new Dexie("MyDatabase");

See their docs

Thanks @David. The docs landed me to this solution. It runs without error:

import Dexie from "dexie";
// @ts-ignore there is not a type for the fake indexeddb
import indexedDB from 'fake-indexeddb';

class TestDatabase extends Dexie {
    constructor() {
        const IDBKeyRange=require("fake-indexeddb/lib/FDBKeyRange");
        super("test",{
            indexedDB: indexedDB,
            IDBKeyRange: IDBKeyRange,
        });
        this.version(1).stores({
            data: "id, name"
        });
    }
}


test("dexie", async ()=>{
    const db = new TestDatabase();
    await db.table("data").put({id: "x", name: "xname"});
    const x=await db.table("data").get("x");
    expect (x.name).toEqual("xname");

    const x2=await db.table("data").where("id").equals("x").toArray();
    expect (x2[0].name).toEqual("xname");
})

Great. Your solution is less obtrusive than require("fake-indexeddb/auto").
