Research direction

Start with the linked react-sqljs-demo, then inspect src/App.js and the referenced craco.config.js around the sql.js/dist/sql-wasm.wasm import and initSqlJs call. Reproduce the loader and useEffect errors with the reported React version. Done means an existing SQLite database can be loaded and queried offline in the React app without the reported import or WASM errors.

Written by the indexing model from the issue text.

Description

I want to make sqlite db and browser work together offline in reactJS. I am using "react": "^17.0.2",

It seems there is a sqljs, sql-js and sql.js existing at the same time. Why do you use - in the name? To confuse?

I dare to install new version of it and used this demo
https://github.com/sql-js/react-sqljs-demo

And it complains on import string

import sqlWasm from "!!file-loader?name=sql-wasm-[contenthash].wasm!sql.js/dist/sql-wasm.wasm";

src/App.js
Line 6:1: Unexpected '!' in '!!file-loader?name=sql-wasm-[contenthash].wasm!sql.js/dist/sql-wasm.wasm'. Do not use import syntax to configure webpack loaders import/no-webpack-loader-syntax

After I delete !! in it it complains on

  useEffect(async () => {
    // sql.js needs to fetch its wasm file, so we cannot immediately instantiate the database
    // without any configuration, initSqlJs will fetch the wasm files directly from the same path as the js
    // see ../craco.config.js
    try {
      const SQL = await initSqlJs({ locateFile: () => sqlWasm });
      setDb(new SQL.Database());
    } catch (err) {
      setError(err);
    }
  }, []);

put async inside useEffect. I just want to extract some data from SQLite DB offline

Maybe you could provide code to work with existing DB on localhost offline with use of react ?

P.S.
another approach doesn't work for me either even I put wasm file in the root folder
