Database not initializing properly

[AceIsHuman]

Creating a database with and without a web worker causes errors like this.worker_.postMessage is not a function and workerRef.queryManager is not a constructor.

Node v16.17.1
Electron v20.3.0
Vue 2.6.12

Jsstore did previously work on node v14.20.0. Could this be an issue related to Node, and is there any possible workaround while using v16.17.1?

I'm having the same issue.

For me, while working without a web worker via workerInjector it gives workerRef.queryManager is not a constructor issue. The full error print:

jsstore.commonjs2.js?b6ae:359 Uncaught TypeError: workerRef.QueryManager is not a constructor
    at ConnectionHelper.initQueryManager_ (jsstore.commonjs2.js?b6ae:359:1)
    at Object.setup (index.js?94b5:1:160)
    at Connection.addPlugin (jsstore.commonjs2.js?b6ae:820:1)

I can't upgrade the version post 4.3.10 due to this. 4.4.0 and above gives error.

I have a Webpack 4 configurated React app that was perfectly running with JsStore 4.3.9 (4.3.10 also works fine), then decided to upgrade to 4.4.4 but had workerRef.queryManager is not a constructor issue.

When I import "workerInjector" to use JsStore without web worker, I can see that Webpack is doing its job to import the module. Because when I console.log it, I see the printed workerInjector variable.

import workerInjector from 'jsstore/dist/worker_injector';

console.log(workerInjector) -> {setup: ƒ setup(r,e)}

I assume the problem occurred after the changes to the library related to compression or Webpack 5.

Any ideas? @ujjwalguptaofficial

yeah it must be broken after upgrading to webpack5. Will try to reproduce and fix ASAP.

@AceIsHuman @alisabrigok issue has been fixed in v - 4.4.5. Please install and let me know.

The issue got introduced due to webpack upgrade, i have also added some test cases - so that it don't ger reproduced again.

[alisabrigok]

I just installed version 4.4.5 and it fixed my issue. Thanks for the swift replies and fixes @ujjwalguptaofficial

Just updated to 4.4.5 and the issue seems to be fixed for connection.initDb(database) without web worker, using the workerInjector plugin.

I cannot get the database to initialize with a web worker. The following code does not produce an error, it just gets hung up on line 5 at initDb.

// connection.js
1 import { Connection } from 'jsstore'
2 import * as JsStoreWorker from 'jsstore/dist/jsstore.worker.commonjs2.js'
3
4 const connection = new Connection(new Worker(JsStoreWorker.default))
5 const isDbCreated = await connection.initDb(getDatabase())

I have also tried creating a preload script in place of the import on line 2. This produces the same result.

// preload.js
const workerPath = require('file-loader?name=scripts/[name].[hash].js!jsstore/dist/jsstore.worker.js').default

// connection.js
4 const connection = new Connection(new Worker(workerPath))

@AceIsHuman can you please give me something reproducable. I am not able to get from your snippets where things can be wrong.

[AceIsHuman]

I created a repo with the error here. https://github.com/AceIsHuman/jsstore-webworker-issue

[ujjwalguptaofficial]

the worker is not being initialized properly @AceIsHuman , i checked out the repo and i see html code inside jsstore worker.

[AceIsHuman]

Any idea why this might happen? When I go to the actual worker path that is in the console log, the js file does contain the worker script.

[AceIsHuman]

I get the same result when using:

import * as JsStoreWorker from 'jsstore/dist/jsstore.worker.commonjs2.js'
const jsStoreWorker = new Worker(JsStoreWorker.default)
