问题
I have been following this guide https://www.apollographql.com/docs/angular/recipes/webpack/ but I am getting this error when I execute ng serve:
ERROR in ./src/app/shared/queries.graphql 1:6
Module parse failed: Unexpected token (1:6)
You may need anappropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
query supplierByName($value: String) { | Supplier(filter: { name: $value }) { | name
Also, when I execute ng build everything is built without any errors.
Basicly what I am trying to do is to load queries from .graphql files directly into my typescript files. See this question I posted related to this.
If there is some info I have forgotten to add please let me know and I will update the question.
this is my angular.json file:

this is my custom-webpack.config.js (in same dir as angular.json):

const path = require('path');
const webpack = require('webpack'); //to access built-in plugins
module.exports = {

test: /\.scss$/,

plugins: () => [ require('postcss-short')() ]
}
},
{
test: /\.(graphql|gql)$/,
exclude: /node_modules/,
loader: 'graphql-tag/loader'
}
]
},
plugins: [
new WebpackNotifierPlugin({
alwaysNotify: true,
title: 'App Name',
contentImage: path.join(__dirname, 'image.png')
})
]
};

query supplierByName($value: String) {
Supplier(filter: { name: $value }) {

回答1:
I found the problem. It was in my angular.json file.
I had only changed the "build" part to use the new builder (@angular-builders/custom-webpack:browser).
The "serve" part also needed a different builder (@angular-builders/custom-webpack:dev-server).
My final angular.json file that is now working:
