Research direction

Start with the sql-wasm.js request and the custom webpack configuration shown in the issue, then inspect how the Ionic application serves the sql-wasm.wasm asset. Done means the asset no longer returns 404 and TypeORM can initialize sql.js without the fetching error.

Written by the indexing model from the issue text.

Description

Hello, I'm trying to use sql.js with typeorm in an ionic@6 application, but the following error happens:

zone.js:1523          GET http://localhost:8100/sql-wasm.wasm 404 (Not Found)
Error: both async and sync fetching of the wasm failed
    at Object.Module.onAbort (sql-wasm.js:40:20)
    at I (sql-wasm.js:104:97)
    at lb (sql-wasm.js:105:136)
    at sql-wasm.js:105:408
    at ZoneDelegate.invoke (zone.js:400:1)
    at Object.onInvoke (core.mjs:25488:1)

    at Zone.run (zone.js:160:1)
    at zone.js:1318:1
    at ZoneDelegate.invokeTask (zone.js:434:1)

My custom webpack:

const webpack = require('webpack');
console.log('The custom config is used');
module.exports = {
  plugins: [
    new webpack.ProvidePlugin({
      'window.SQL': 'sql.js/dist/sql-wasm.js'
    }),
    new webpack.NormalModuleReplacementPlugin(/typeorm$/, function (result) {
      result.request = result.request.replace(/typeorm/, "typeorm/browser");
    })
  ],

  resolve: {
    fallback: {
      fs: false,
      net: false,
      tls: false
    }
  }
};

My Ionic Info:

I'm using sql.js@1.3.2 typeorm@0.2.41

Would anyone have a solution?
