Pass custom parameters to mutator

[mbwestphal]

In the mutator function I need more information available to transform the data I receive.

Is there a way to pass the definition $ref to the mutator (or something like that)?

I have a similar usecase for both mutators and GET API calls, I need to extend the generated API calls to require a customParam parameter like this:

export const getData = async (
  params?: GetDataParams,
  options?: RequestInit,
  customParam: string,
): Promise<getDataResponse> => {
  return fetchWrapper<Promise<getDataResponse>>(
    getGetUpcomingAuctionsUrl(params),
    {
      ...options,
      method: 'GET',
    },
    customParam
  );
};

Is there anyway to add custom parameters to the generated API functions.

My current orval config is this

 input: './specs/api/openapi.yaml',
    output: {
      mode: 'split',
      schemas: './generated/api/types',
      target: './generated/api/api.ts',
      mock: { type: 'msw', delay: 10, useExamples: false },
      prettier: true,
      client: 'fetch',
      override: {
        mutator: {
          path: './api/fetchWrapper.ts', 
          name: 'fetchWrapper',
        },
      },
    },

We have accomplished this using jscodeshift (GitHub).

You pass all files to your jscodeshift transform (e.g. transform.cjs) using orvals afterAllFilesWrite setting:

import {run} from 'jscodeshift/src/Runner.js';
// snip
afterAllFilesWrite: [paths => run('./transform.cjs', paths, {parser: 'ts'})]

And in your transform.cjs you find the callee ending with Mutator and you add another argument.

It is kind of rough, but it works and it is not too much additional source code.
