Guide to importing a Swagger model barrel file into a Typescript file (Angular)

Our team is currently using Swagger to automatically generate our API models and we are looking for a more convenient way to import them into our project.

Currently, we are importing them like this: tsconfig.ts

"paths": {
  "apimodel/*": ["frontend/swagger-api-definition/model/*"]
}

Example of importing random data-source classes:

import { ExampleDtoQuery } from 'apimodel/exampleDtoQuery ';
import { ExampleUserDtosUserManagerDashboardResponseUserProject } from 'apimodel/exampleUserDtosUserManagerDashboardResponseUserProject ';

Please note that the names used above are randomly generated and should not be judged :)

However, I would like to set up an alias in the tsconfig file and utilize the barrel file generated in the root directory. Something like this: tsconfig.ts

"paths": {
  "@apimodel": ["frontend/swagger-api-definition/index.ts"]
},

Example of importing random data-source classes with the alias:

import { ExampleDtoQuery } from '@apimodel';
import { ExampleUserDtosUserManagerDashboardResponseUserProject } from '@apimodel ';

Unfortunately, when trying this approach, the compiler throws an error message:

Cannot find module '@apimodel'.ts(2307)

Any suggestions on how to resolve this issue?

Answer №1

If you include a * in the path declaration, it instructs the TS compiler to permit imports from anything prefixed with @apimodel/. It is crucial to also specify a baseUrl, or else the TS compiler may struggle to locate the barrel file referenced. To ensure everything functions correctly, consider revising both the paths and baseUrl definitions as follows:

"baseUrl": "./",
"paths": {
  "@apimodel": ["frontend/swagger-api-definition/index.ts"]
},
