Issue
When I updated Angular from 7 to Angular 8, getting error for lazy loading modules
I have tried the options, which are there in the angular upgradation guide
Made the below changes:
Before
loadChildren: '../feature/path/sample-
tage.module#SameTagModule'
After
loadChildren: () => import('../feature/path/sample-
tags.module').then(m => m.CreateLinksModule)
error TS1323: Dynamic import is only supported when '--module' flag is 'commonjs' or 'esNext'.
Solution
You are using dynamic import so you have to change your tsconfig.json like this to target your code to esnext
module
{
"compileOnSave": false,
"compilerOptions": {
"baseUrl": "./",
"outDir": "./dist/out-tsc",
"sourceMap": true,
"declaration": false,
"module": "esnext", // add this line
"moduleResolution": "node",
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"importHelpers": true,
"target": "es2015",
"typeRoots": [
"node_modules/@types"
],
"lib": [
"es2018",
"dom"
]
}
}
Also make sure to check tsconfig.app.json dont have module and target config something like this
{
"extends": "./tsconfig.json",
"compilerOptions": {
"outDir": "./out-tsc/app",
"types": []
},
"include": [
"src/**/*.ts"
],
"exclude": [
"src/test.ts",
"src/**/*.spec.ts"
]
}
