Is there a way to remove "TypeError: Expected signal to be an instanceof AbortSignal"?

https://github.com/node-fetch/node-fetch/blob/master/src/request.js?ts=2#L120

This line causing problem

Let’s check out ths isAbortSignal function

When would it happen?

After Webpack bundle my code, code minification would change the name,
object[NAME] === 'AbortSignal' is not true anymore so this error would pop up, The only solution is to turn off code minification There should be a better way than this

Propose (What to do next)

1. Delete this part altogether, don’t check the name
2. Don’t compare with string ‘AbortSignal’ like this object[NAME] === 'AbortSignal', in Ruby we have class.name to get the class name, I am not sure what’s the equivalent in JS

Maybe this StackOverflow question helpful: How to get a JavaScript object’s class?

Thanks

For those using esbuild, an equivalent solution to 1c7’s solution is to set the “keepNames” option to true.

Done, fixed it

Enviroment

• Electron.js 8.0.0
• “vue-cli-plugin-electron-builder”: “^1.4.5”
• “@azure/storage-blob”: “12.1.1”

Solution：

This can still minify code, but, without mangle with the class name and function name

vue.config.js

const TerserPlugin = require('terser-webpack-plugin');
module.exports = {
 pluginOptions: {
  electronBuilder: {
   chainWebpackMainProcess: config => {
    config.plugins.delete('uglify')
    config.plugin('uglify').use(TerserPlugin, [{
     terserOptions: {
      mangle: false,
      sourceMap: true,
      compress: false,
      keep_classnames: true,
      keep_fnames: true,
      output: {
       comments: false,
      },
     }
    }])
    config.optimization.minimize(false);
    console.log(config.toString())
   },
  }
 },
}

Result (This worked)

This is src/background.js file after running npm run electron:build

For comparison (This doesn’t work)

node-fetch would raise error
