## 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](d180f47e16/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
Allow `medusa-oas` CLI to generate API client code from an OAS json file.
## Why
Manually maintaining API clients is time consuming and error prone. We wish to automate the process by using code generation strategies.
We also wish to eliminate direct import from `@medusajs/medusa` in clients which can lead to unwanted side effects like importing unnecessary dependencies.
## How
Fork and customize an OAS code generator library that is TypeScript friendly.
Attempt to match the interface and signature of our current client packages: `@medusajs/medusa-js`, `medusa-react`
Add a new `client` command to the `medusa-oas` CLI as the main interface to interact with the code generation tooling.
## Test
### Prerequisites
* From the root of the monorepo:
* `yarn install`
* `yarn build`
### Case - all in one build
* From the root of the monorepo:
* Run `yarn medusa-oas oas --out-dir ~/tmp/oas --type store`
* Run `yarn medusa-oas client --src-file ~/tmp/oas/store.oas.json --out-dir ~/tmp/client-store --type store`
* Expect `~/tmp/client-store` to contain the following files and directories:
```
core/
hooks/
models/
services/
index.ts
MedusaStore.ts
useMedusaStore.tsx
```
### Case - types only
* From the root of the monorepo:
* Run `yarn medusa-oas oas --out-dir ~/tmp/oas --type store`
* Run `yarn medusa-oas client --src-file ~/tmp/oas/store.oas.json --out-dir ~/tmp/client-types --type store --component types`
* Expect `~/tmp/client-types` to contain the following files and directories:
```
models/
index.ts
```
### Case - client only
* From the root of the monorepo:
* Run `yarn medusa-oas oas --out-dir ~/tmp/oas --type store`
* Run `yarn medusa-oas client --src-file ~/tmp/oas/store.oas.json --out-dir ~/tmp/client-only --type store --component client --types-package @medusajs/client-types`
* Expect `~/tmp/client-only` to contain the following files and directories:
```
core/
services/
index.ts
MedusaStore.ts
```
