HTTP ​

HTTP crash course is great overview.

Caddy is amazing for self hosting servers. HTTPie, HTTP Toolkit, Hurl & xh are useful. HTTP Docs has nice overview.

Status code summary (as cats) is fun summary.

1xx: hold on
2xx: here you go
3xx: go away
4xx: you fucked up
5xx: I fucked up

kawipiko is neat static HTTP server. Svix is nice for webhooks.

Notes ​

• HTTP return codes cheat sheet: 1** Hold on 2** Here you go 3** Go away 4** You fucked up 5** I fucked up
• jo | curl --json | jq is great.
• Best HTTP API is one that provides me a client in the language I am using
