I redesigned my personal website on the flight from Doha back to Toronto. Last year’s design took me a day and used a content management framework called Quartz, while the new design took me only about two hours in codex, and used only Astro as a lightweight framework. I used the plan mode in codex to produce a plan first before implementation. I have to say, codex completely changed how website is to be designed: the old days of manually coding websites are gone.
The new website allows creating a new post with a CLI tool: bun run new -- --title "My New Post", which is codex friendly.
