[oats-runtime] TS6133: types and RequestContext is declared but its value is never read.

[serbanghita]

Problem:

A openapi.yaml file containing only models (schemas) and no urls, will generate a client.ts file what throws TS6133 in the context of tsconfig.json configured with

     "noUnusedLocals": true,
    "noUnusedParameters": true,  

This will cause builds that are using the generated code to fail at compile time.

How to reproduce:

Create openapi.yaml file with the following contents:

openapi: 3.0.0
info:
  title: A test without urls
  version: 0.0.1
  description: Types for
servers: []
paths: {}

components:
  schemas:
    User:
      type: object
      properties:
        id:
          type: integer
        name:
          type: string

Run generate.js which contains the boilerplate code from README.md:

TS6133: types is declared but its value is never read.
TS6133: RequestContext is declared but its value is never read.

According to microsoft/TypeScript#12913 one solution would be to add // @ts-ignore or // @ts-nocheck (optionally) on top of the generated file.

Immediate solution:

header: ['// @ts-nocheck', '/* tslint:disable variable-name only-arrow-functions*/'].join("\n"),

Programmatic solution:

How about:

1. adding // @ts-expect-error above EndpointsWithContext variable node
2. adding // @ts-expect-error node above const types = generateImport('types', typemodule);
