I have create a new vue 3 project (using vue-cli) with primevue and typescript. I have tried to add a DataTable component (in HelloWorld.vue file), but got the following error [1].
Project can be checked out at
I also tried to checkout the primevue quickstart project (the ... quickstart) and use the DataTable component and that worked.
Any idea why I get the error? I can see that this is related vue-loader, but I do not know what the problem is and how should be fixed.

Code: Select all

 error  in ./node_modules/primevue/components/datatable/DataTable.vue?vue&type=script&lang=js
Module parse failed: Unexpected token (310:67)
File was processed with these loaders:
 * ./node_modules/cache-loader/dist/cjs.js
 * ./node_modules/vue-loader-v16/dist/index.js
You may need an additional loader to handle the result of these loaders.
|         if (this.reorderableColumns) {
|             let columnOrder = [];
>             this.columns.forEach(col => columnOrder.push(col.props?.columnKey||col.props?.field));
|             this.d_columnOrder = columnOrder;
|         }

 @ ./node_modules/primevue/components/datatable/DataTable.vue?vue&type=script&lang=js 1:0-160 1:0-160 1:161-310 1:161-310
 @ ./node_modules/primevue/components/datatable/DataTable.vue
 @ ./node_modules/primevue/datatable.js

Answering my own question... The issue here was related to the optional chaining operator (that ? from the error) added in typescript 3.7. Issue was fixed by adding babel and the default config file babel.config.js. I still don't know what is the cause of the issue...
So, next time when using primevue with vue 3 make sure to use babel as well.
I guess the post can be closed now. Thanks

Hey, could you please share some more details on how to fix this issue? What do you mean exactly by 'make sure to use babel'? Im new to all this and I am using WebpackEncore and running into the exact same issue. TY.

Edit: I guess I am continuing the same way as the OP by answering my own question :D

I added this to my webpack.config.js file (I am using webpack encore).

.configureBabel(function(babelConfig) {
}, {
includeNodeModules: ['primevue']

You need to install @babel/plugin-proposal-optional-chaining, add it as a plugin, and include the primevue node modules to be parsed by babel.

Hope this helps to anyone that stumbles upon this thread.
