API

Linear API is interestingly made. Stripe has nice API docs too. Currently looking into Apiker for releasing my APIs.

Redocusaurus seems nice for API docs. Svix is great for webhooks. tRPC is nice for API access.

Love using Dash and it's Alfred workflow on macOS for searching docs.

Notes

• API should be only sending values it actually has or at least not null but same type values: e.g. items array should never turn null even if empty but rather an empty array.
• APIs should be built around the needs of the consumers, not the providers
• Treat users as "busy" rather than "idiots". Don't underestimate users. Build libraries, not (just) scripts. Teach by example. With this perspective, good API design falls into place: 1. Layered API with good defaults. 2. Short high-currency examples. 3. Paced introduction to more concepts.
