The Challenge
Hello everyone,
I am currently working with TypeScript 3.0.3 and cypress, and I'm facing an issue while trying to import the react-relay-network-modern module in my component. Despite having the module present in my node_modules folder and also defined in my package.json, I keep getting an error stating that the module doesn't exist. Interestingly, there are no issues when importing relay-runtime and I have successfully integrated relay into my project.
Whenever I attempt a standard import like this:
import * as RelayNetworkModern from 'react-relay-network-modern';
I encounter the following error indicating that the module was not found.
/src/relayEnvironment.ts
[tsl] ERROR in /src/relayEnvironment.ts(8,37)
TS2307: Cannot find module 'react-relay-network-modern'.
Even after setting up aliases both in my tsconfig.json and webpack preprocessor or trying to import subfolders within
react-relay-network-modern/(es|lib|...)Configuration Details
Let me share my configuration files with you:
/cypress/plugins/webpack.config.js
const webpack = require( '@cypress/webpack-preprocessor' );
const path = require('path');
const options = {
watchOptions: {},
webpackOptions: {

modules: [
path.resolve( __dirname, '../../node_modules' ),
path.resolve( __dirname, '../../src' ),
],
alias: {
'react-relay-network-modern': path.resolve( __dirname, '../../node_modules/react-relay-network-modern/es' ),
src: path.resolve( __dirname, '../../src' ),
}
},
module: {

},
},

],
},
],
},
},
};
module.exports = webpack( options );
