问题
Our team at my company has encountered an issue which we can't seem to find the solution to and I was hoping someone here could help us out. We use AWS Amplify in our Angular 10/Ionic 5 project and we do get the following error:
Uncaught ReferenceError: exports is not defined

Here is a snippet from our package.json. I was wondering if this issue has anything to do with webpack or if it is Angular/Typescript/Ionic related.

We have also included (tsconfig.app.json):
"angularCompilerOptions": {
"enableIvy": false,
"fullTemplateTypeCheck": false
},
I have found multiple sources with different problems with AWS Amplify and Ionic/Angular but non of them seem to be the same as your problem.
回答1:
Try:
rm -rf node_modules
rm package-lock.json
npm i
it helped in our case.
回答2:
Got the same issue (Angular 10) and solved it by following a workaround found on the aws-sdk-js GitHub Issue page here.
In short, you have to follow 2 steps below:
Install the node typings with
npm i --save-dev @types/node(I know this is weird since we are on a front-end app but the AWS SDK does require node typings)add
"types": ["node"]in the"compilerOptions"section of yourtsconfig.app.jsonfile.
In my case, tsconfig.app.json file becomes:
{
"extends": "./tsconfig.json",
"compilerOptions": {
"outDir": "./out-tsc/app",
"types": [
"node"
]
},
"files": [
"src/main.ts",
"src/polyfills.ts"
],
"include": [
"src/**/*.ts",
"src/**/*.d.ts"
],
"exclude": [
"src/**/*.spec.ts"
]
}
