The paths configuration in tsconfig.json is not functioning as anticipated

I've been encountering a module not found error while trying to work with jasmine-ts. To troubleshoot, I decided to use tsc and inspect my folder structure:

\src\app\...
\src\tests\...

To address this issue, I created a tsconfig.json at the 'tests' level as shown below:

{
    "compileOnSave": false,
    "compilerOptions": {
        "baseUrl": "../", 
        "paths": {
            "@app/*": [
                "app/*"
            ] 
        }
    }
}

Even after importing a module from the app directory in my '*.test.ts' file, I still receive a module not found error:

Cannot find module '@app/core/data/my-module'

I attempted to run the following command:

tsc --traceResolution test1.test.ts

which produced the following output:

test1.test.ts:2:23 - error TS2307: Cannot find module '@app/core/data/my-module'. 

2 import { Field } from '@app/core/data/my-module'
                         ~~~~~~~~~~~~~~~~~~~~~~~~~~

Answer №1

Have you attempted this method?

In your tsconfig.json file:

{
  "compilerOptions": {
    "baseUrl": "src",
    "paths": {
      "@pages/*": ["app/pages/*"],
      "@environment": ["environments/environment"]
    }
  },
}

When importing:

import { LoginComponent } from '@pages/login/login.component';

import { environment } from '@environment';

This solution has been successful for me.

Answer №2

Consider

"baseUrl": "src"

as an alternative to

"baseUrl": "../",  

within your tsconfig.json file
