## What
New `medusa-oas docs` to improve OAS compatibility with for Redocly API documentation viewer and handle deep circular references.
## Why
We wish to share the tooling we have been using to generate our public API documentation.
## How
* Move `/docs-utils/redocly` under `medusa-oas-cli` package.
* Move some of the operations from `oas-github-ci/scripts/build-openapi.js` under the `medusa-oas docs` command.
* Improve DevX when dealing with circular references by outputting precise troubleshooting recommendations in the error message.
* Extract some common operations in utility methods.
## Tests
### Step 1
* Run `yarn install`
* Run `yarn build`
* Run `yarn openapi:generate --dry-run`
* Expect same behaviour as before where OAS is validated and circular references are checked.
### Step 2
* Run `yarn openapi:generate`
* Expect same behaviour as before where API documentation is generated in `/docs`
### Step 3
* Move to the `packages/oas/medusa-oas-cli`
* Run `yarn medusa-oas oas --type store --out-dir ~/tmp/oas` to generate the raw OAS file.
* Run `yarn medusa-oas docs --src-file ~/tmp/oas/store.oas.json --preview`
* Open url from the console output in a browser
* Expect a preview of the API documentation using Redocly.
### Step 4
* Run `yarn medusa-oas docs --src-file ~/tmp/oas/store.oas.json --out-dir ~/tmp/docs/store --clean --split`
* Expect a similiar output as `yarn openapi:generate`
### Step 5
* Run `yarn medusa-oas docs --src-file ~/tmp/oas/store.oas.json --out-dir ~/tmp/docs/store --clean --html`
* Expect `index.html` to have been created.
* Run `npx http-server ~/tmp/docs/store -p 8000`
* Open http://127.0.0.1:8000 in a browser.
* Expect a zero-dependency static rendering of the API documentation using Redocly.
### Step 6
* To emulate an unhandled circular reference, edit [packages/oas/medusa-oas-cli/redocly/redocly-config.yaml](https://github.com/medusajs/medusa/blob/d180f47e1609e74f46f72cdeef6265a654da3e7e/packages/oas/medusa-oas-cli/redocly/redocly-config.yaml#L9-L10) and comment out "Address: - Customer"
* Run `yarn medusa-oas docs --src-file ~/tmp/oas/store.oas.json --dry-run`
* Expect an error message with a hint on how to resolve the issue.
* Create a file `~/tmp/redocly-config.yaml` and paste in the recommendation from the error message.
* Run `yarn medusa-oas docs --src-file ~/tmp/oas/store.oas.json --dry-run --config ~/tmp/redocly-config.yaml`
* Expect Dry run to succeed.
* feat(oas:cli): output better error when no command is provided
* chore(changeset): patch

## What
Introduce a CLI for extracting OAS from the core `medusa` package.
## Why
We need to decouple OAS tooling from documentation tooling in order to allow packages and external systems to leverage our OAS has a dependency.
## How
Introduce a new OAS workspace within packages in order to organize current and future OAS related package. Only 1 OAS package for now.
Introduce a new CLI only package to act as the main gateway for all upcoming OAS tooling. Only 1 command for now.
Update documentation tooling pertaining to OAS to use the CLI instead.
## Test
### Prerequisite
From the monorepo root:
* `yarn install`
* `yarn build`
### Documentation
#### Case - validation only - success
* Run `yarn openapi:generate --dry-run`
* Expect console output `🟢 Valid OAS` but no mention of `🔵 Exported OAS`
#### Case - validation only - invalid
* Introduce a bug by renaming `@schema Cart` to `@schema Kart` in [models/cart.ts](https://github.com/medusajs/medusa/blob/0adb0d9ff96087613b7a634cbc97a7e301b01121/packages/medusa/src/models/cart.ts#L2)
* Run `yarn build` to update `@medusajs/medusa` package with the bug.
* Run `yarn openapi:generate --dry-run`
* Expect console output `🔴 Invalid OAS` with a stack trace of the issue.
#### Case - docs generation
* Run `yarn openapi:generate`
* Expect `docs/api/` directory to contain:
* `admin.oas.json` (raw OAS)
* `store.oas.json` (raw OAS)
* `admin.oas.yaml` (sanitized OAS)
* `store.oas.yaml` (sanitized OAS)
* `admin/` (updated redocly split output)
* `store/` (updated redocly split output)
### CLI
#### Case - crawl additional paths
* From a local medusa server (`medusa-starter-default`), add an `index.ts` file in `src/models/`
* In the `index.ts`, add dummy OAS JSDoc like `/** @schema Foobar */`
* From the root of the monorepo, run `yarn medusa-oas --type store --paths path-to-medusa-server/src`
* Expect a `store.oas.json` to be created at the root of the monorepo.
* The `store.oas.json` should contain an additional `Foobar` entry in `components.schemas`.
