OpenAPI Codegen for TypeScript-friendly MSW testing

Provides an adapter layer method for @darkpatternsdigital/openapi-codegen-typescript to integrate with msw.

npm i @darkpatternsdigital/openapi-codegen-typescript
npm i -D @darkpatternsdigital/openapi-codegen-typescript-msw

You must also have the .NET 8.0 runtime installed on your machine.

This will provide a corresponding bin to generate the typescript files. (See the @darkpatternsdigital/openapi-codegen-typescript package for command line usage details.)

openapi-codegen-typescript api.yaml api-generated/ -c

You can then create a mock MSW service to handle specific requests:

import { setupServer } from 'msw/node';
import { toMswHandler } from '@darkpatternsdigital/openapi-codegen-typescript-msw';
import operations from './api-generated/operations';

const baseDomain = 'http://localhost/';
const findPets = toMswHandler(operations.findPets, { baseDomain });
const server = setupServer(
    findPets(
        { params: { tags: ['dog','cat'], limit: 10 } },
        { statusCode: 200, data: [{ name: 'Fido', tag: 'dog', id: 1234 }], mimeType: 'application/json' }
    )
);

This API will use the type safety from OpenAPI along with msw.
