The reason for this error is because Nuxt edge uses webpack 4 & the newer version of vue-loader. vue-loader changed how it handles components & Nuxt adjusted their webpack config accordingly. You can see the webpack config changes here.

Because of this the object reference here doesn't exist in Nuxt edge.

To fix it you must adjust the Typescript module ~/modules/typescript.js. So it would look something like so:

module.exports = function () {
  // Add .ts & .tsx extension to Nuxt
  this.nuxt.options.extensions.push('ts', 'tsx')

  // Extend webpack build
  this.extendBuild(config => {
    // Add TypeScript
      test: /\.tsx?$/,
      loader: 'ts-loader',
      options: { appendTsSuffixTo: [/\.vue$/] }

    // Add .ts extension in webpack resolve
    if (! config.resolve.extensions.includes('.ts')) {

    // Add .tsx extension in webpack resolve
    if (! config.resolve.extensions.includes('.tsx')) {

You'll also have to update ts-loader to version 4.x since version 3.x only support webpack 2 | 3.

After making those changes Nuxt edge should run without any issues.

Just wanted to create same bug report! To make it work I just checked whether the object exists and if not - create a new one before pushing 'ts' extension into it.

if (rule.loader === 'vue-loader') {
          if(!rule.options.loaders)rule.options.loaders = {}
        rule.options.loaders.ts = tsLoader

but I guess @haleksandre provided a better solution, I'm only curious about this part of the config:

// Add TypeScript
      test: /\.tsx?$/,

why are we only testing for .tsx and not for .ts also?

@AndrewBogdanovTSS It is testing for both. ? in regex means zero or one of whatever is before, in this case x. So the test will match .ts as well as .tsx.

If you don't plan on using .tsx you can remove x? from the test regex.

I can confirm this works :). Great thanks @haleksandre.
