Cal.com Public API (Enterprise Only)
This will be the new public enterprise-only API
This is the public REST api for cal.com
NextJS + TypeScript
It's a barebones NextJS + TypeScript project leveraging the nextJS API with a pages/api folder.
No react
It doesn't have react or react-dom as a dependency, and will only be used by a redirect as a folder or subdomain on cal.com with maybe a v1 tag like:
api.cal.com/v1
api.cal.com/api/v1
API Endpoint Validation
Zod
The API uses zod
library like our main web repo. It validates that either GET query parameters or POST body content's are valid and up to our spec. It gives appropiate errors when parsing result's with schemas.
Next Validations
Next-Validations Docs Next-Validations Repo We also use this useful helper library that let's us wrap our endpoints in a validate HOC that checks the req against our validation schema built out with zod for either query and / or body's requests.
Testing with Jest + node-mocks-http
We aim to provide a fully tested API for our peace of mind, this is accomplished by using jest + node-mocks-http
Next.config.js
Redirects
Since this will only support an API, we redirect the requests to root to the /api folder. We also added a redirect for future-proofing API versioning when we might need it, without having to resort to dirty hacks like a v1/v2 folders with lots of duplicated code, instead we redirect /api/v*/:rest to /api/:rest?version=*
The priority is the booking-related API routes so people can build their own booking flow, then event type management routes, then availability management routes etc
How to add a new model or endpoint
Basically there's three places of the codebase you need to think about for each feature.
/pages/api/
- This is the most important one, and where your endpoint will live. You will leverage nextjs dynamic routes and expose one file for each endpoint you want to support ideally.
How the codebase is organized.
The example resource -model- and it's endpoints
pages/api/endpoint/
GET pages/api/endpoint/index.ts - Read All of your resource POST pages/api/endpoint/new.ts - Create new resource
pages/api/endpoint/[id]/
GET pages/api/endpoint/[id]/index.ts - Read All of your resource PATCH pages/api/endpoint/[id]/edit.ts - Create new resource DELETE pages/api/endpoint/[id]/delete.ts - Create new resource
/tests/
This is where all your endpoint's tests live, we mock prisma calls. We aim for at least 50% global coverage. Test each of your endpoints.
/tests/endpoint/
/tests/endpoint/resource.index.test.ts - Test for your pages/api/endpoint/index.ts file tests/endpoint/resource.new.test.ts - Create new resource
/tests/endpoint/[id]/
/tests/endpoint/[id]/resource.index.test.ts
- Read All of your resource
/tests/endpoint/[id]/resource.edit.test.ts
- Create new resource
/tests/endpoint/[id]/resource.delete.test.ts
- Create new resource
/lib/validations/yourEndpoint.ts
- This is where our model validations, live, we try to make a 1:1 for db models, and also extract out any re-usable code into the /lib/validations/shared/ sub-folder.
