61a932f8f5 feat: OAuth2 controller api v2 + refactor oAuth Trpc handlers (#25989)
* feat(api-v2): add OAuth2 controller skeleton for auth module

- Add new OAuth2 module under /auth with controller, service, repository, and DTOs
- Implement skeleton endpoints:
  - GET /v2/auth/oauth2/clients/:clientId - Get OAuth client info
  - POST /v2/auth/oauth2/clients/:clientId/authorize - Generate authorization code
  - POST /v2/auth/oauth2/clients/:clientId/exchange - Exchange code for tokens
  - POST /v2/auth/oauth2/clients/:clientId/refresh - Refresh access token
- Create input DTOs for authorize, exchange, and refresh operations
- Create output DTOs for client info, authorization code, and tokens
- Register OAuth2Module in endpoints.module.ts

* chore: add missing functions to platform libraries

* feat(api-v2): integrate OAuthService from platform-libraries into OAuth2 controller

- Add OAuthService export to platform-libraries
- Refactor OAuth2Service to use OAuthService.validateClient() and OAuthService.verifyPKCE()
- Remove duplicate local implementations of validateClient and verifyPKCE methods

Co-Authored-By: morgan@cal.com <morgan@cal.com>

* feat(api-v2): use local validateClient and verifyPKCE implementations

- Reimplement validateClient and verifyPKCE methods locally in OAuth2Service
- Use verifyCodeChallenge and generateSecret from platform-libraries directly

* refactor(api-v2): separate repositories for OAuth2, access codes, and teams

- Create AccessCodeRepository for access code Prisma operations
- Add findTeamBySlugWithAdminRole method to TeamsRepository

* refactor: error handling

* refactor: error handling

* refactor: error handling

* remove console log

* provide redirectUri in generateAuthCodeHandler

* provide redirectUri in authorize view

* refactor: replace HttpError with ErrorWithCode in OAuth files

- Update OAuthService to use ErrorWithCode instead of HttpError
- Update mapErrorToOAuthError to check ErrorCode instead of status codes
- Update token/route.ts and refreshToken/route.ts to use ErrorWithCode
- Add ErrorWithCode export to platform-libraries
- Use getHttpStatusCode to map ErrorCode to HTTP status codes

Co-Authored-By: morgan@cal.com <morgan@cal.com>

* fix: update generateAuthCode handler to use ErrorWithCode instead of HttpError

The handler was still checking for HttpError in its catch block, but OAuthService
now throws ErrorWithCode. This caused the error messages to be lost and replaced
with 'server_error' instead of the specific error messages.

Co-Authored-By: morgan@cal.com <morgan@cal.com>

* fix: update OAuth2 controller to use ErrorWithCode instead of HttpError

The controller was still checking for HttpError in its catch blocks, but OAuthService
now throws ErrorWithCode. This caused all errors to return 500 Internal Server Error
instead of the correct HTTP status codes (400, 401, 404).

Also added getHttpStatusCode export to platform-libraries.

Description

Cal.com is using the Nest framework TypeScript starter repository.

Installation

$ yarn install

Prisma setup

$ yarn prisma generate

Env setup

Copy .env.example to .env and fill values.

Add license Key to Deployment table in DB

id, logo, theme, licenseKey, agreedLicenseAt:- 1, null, null, '00000000-0000-0000-0000-000000000000', '2023-05-15 21:39:47.611'

Replace with your actual license key.

your CALCOM_LICENSE_KEY env var need to contain the same value

.env CALCOM_LICENSE_KEY=00000000-0000-0000-0000-000000000000

Running the app

Development

$ yarn run start

OR if you don't want to use docker, you can run following command.

$ yarn dev:no-docker

Additionally you can run following command(in different terminal) to ensure that any change in any of the dependencies is rebuilt and detected. It watches platform-libraries, platform-constants, platform-enums, platform-utils, platform-types.

$ yarn run dev:build:watch

If you are making changes in packages/platform/libraries, you should run the following command too that would connect your local packages/platform/libraries to the api/v2

$ yarn local

watch mode

$ yarn run start:dev

production mode

$ yarn run start:prod





## Test

```bash
# unit tests
$ yarn run test

# e2e tests
$ yarn run test:e2e

# e2e tests in watch mode
$ yarn test:e2e:watch 

# run specific e2e test file in watch mode
$ yarn test:e2e:watch --testPathPattern=filePath

# test coverage
$ yarn run test:cov

Conventions

Guards

  1. In case a guard would return "false" for "canActivate" instead throw ForbiddenException with an error message containing guard name and the error.
  2. In case a guard would return "false" for "canActivate" DO NOT cache the result in redis, because we don't want that someone is forbidden, updates whatever was the problem, and then has to wait for cache to expire. We only cache in redis guard results where "canAccess" is "true".
  3. If you use ApiAuthGuard but want that only specific auth method is allowed, for example, api key, then you also need to add @ApiAuthGuardOnlyAllow(["API_KEY"]) under the @UseGuards(ApiAuthGuard). Shortly, use ApiAuthGuardOnlyAllow to specify which auth methods are allowed by ApiAuthGuard. If ApiAuthGuardOnlyAllow is not used or nothing is passed to it or empty array it means that all auth methods are allowed.
