调研方向
Start with the Webpack configuration and the require('sql.js') call, then inspect where initSqlJs fails before locateFile runs. Reproduce the error in the Electron renderer and compare the bundled module/export behavior; done means determining whether the configuration or sql.js causes the error and documenting a verified resolution.

描述
I'm trying to get Sql.js working with TypeORM inside Electron as part of the renderer but I'm running into an error I don't know how to handle. I'm getting the error: TypeError: Cannot set property 'exports' of undefined. I'm not sure if this is a configuration issue on my end or if there's some sort of bug. It seems like the error happens somewhere in initSqlJs before it gets to locating the wasm binary.
My setup is as follows:
WebPack Config
module.exports = {
entry: {main: './main.ts'},
output: {/*Removed for brevity*/},
target: 'electron-renderer',
module: {/*Removed for brevity*/},
plugins: [
/*Other plugins removed for brevity*/
new Webpack.NormalModuleReplacementPlugin(/typeorm$/, function (result) {
result.request = result.request.replace(/typeorm/, "typeorm/browser");
}),
new Webpack.ProvidePlugin({
'window.SQL': 'sql.js/dist/sql-wasm.js'
}),
new CopyPlguin({
patterns: [
{from: './node_modules/sql.js/dist/sql-wasm.wasm'}
]
})
]
}
Main Code
const initSqlJs = require('sql.js');
const SQL = await initSqlJs({
locateFile: (file: any) => {
console.log(file); //This line is never printed
return `https://cdnjs.cloudflare.com/ajax/libs/sql.js/1.1.0/dist/${file}`}
});
var db = new SQL.Database();
